Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This booklet is a report for a case study visit during four day field trip, a group of nine PhD students and their supervisors – all part of the National Research School for Architecture and Planning in the Urban Landscape, APULA – set out to explore what may be considered the outback of Western Europe’s conurbations, the transnational region of Kiruna -Narvik.Both “remote” and “resourceful”, “threatened” and “thriving” (equally relative notions), this region seemed to offer possibilities to reflect upon many of the current tendencies influencing contemporary planning practice and research.

- Background: A successful clinical result is reported in 75% to 85% of impingement patients after arthroscopic subacromial decompression. The result is maintained over time, but few studies have investigated the integrity of the rotator cuff in these patients. Materials and methods: Using ultrasonography, we examined the integrity of the rotator cuff in 70 patients 15 years after arthroscopic subacromial decompression. All patients had an intact rotator cuff at the index procedure. Results: Tendons were still intact in 57 patients (82%), 10 (14%) had partial-thickness tears, and 3 (4%) had full-thickness tears. Discussion: The total number of 18% tears (partial and full thickness) in this study, including patients clinically diagnosed with subacromial impingement at a mean age of 60 years, is unexpectedly low compared with 40% degenerative tears reported in asymptomatic adults of the same age. Conclusion: Arthroscopic subacromial decompression seems to reduce the prevalence of rotator cuff tears in impingement patients. This appears attributable to elimination of extrinsic factors such as mechanical wear and bursitis. The potential effect of surgery on intrinsic cuff degeneration is unknown, but intrinsic factors may explain tears still developing despite decompression.

- Background and purpose Few authors have considered the outcome after acute traumatic rotator cuff tears in previously asymptomatic patients. We investigated whether delay of surgery, age at repair, and the number of cuff tendons involved affect the structural and clinical outcome. Patients and methods 42 patients with pseudoparalysis after trauma and no previous history of shoulder symptoms were included. A full-thickness tear in at least 1 of the rotator cuff tendons was diagnosed in all patients. Mean time to surgery was 38 (6-91) days. Follow-up at a mean of 39 (12-108) months after surgery included ultrasound, plain radiographs, Constant-Murley score, DASH score, and western Ontario rotator cuff (WORC) score. Results At follow-up, 4 patients had a full-thickness tear and 9 had a partial-thickness tear in the repaired shoulder. No correlation between the structural or clinical outcome and the time to repair within 3 months was found. The patients with a tendon defect at follow-up had a statistically significantly lower Constant-Murley score and WORC index in the injured shoulder and were significantly older than those with intact tendons. The outcomes were similar irrespective of the number of tendons repaired. Interpretation A delay of 3 months to repair had no effect on outcome. The patients with cuff defects at follow-up were older and they had a worse clinical outcome. Multi-tendon injury did not generate worse outcomes than single-tendon tears at follow-up.

Treatment of subacromial pain and rotator cuff tears
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Shoulder pain is very common, affecting 14-21 % of the population at some time during their lifetime. The aims of this thesis were to improve the understanding of various aspects concerning the pathogenesis and treatment of subacromial pain and rotator cuff tears. Patients and healthy individuals were examined and compared in five studies:Study I) Seventy patients were retrospectively examined, clinically and with ultrasound, 15 years after arthroscopic subacromial decompression. All patients had an intact rotator cuff at surgery. Ultrasound showed significantly fewer rotator cuff tears compared to the prevalence of asymptomatic tears reported in the literature for the same age group. This indicates that arthroscopic subacromial decompression might protect the rotator cuff.Study II) Forty-two patients were retrospectively examined, clinically and with ultrasound, 39 months (mean) after an acute rotator cuff repair. All patients had pseudoparalysis after trauma, a full thickness tear and no previous history of shoulder symptoms. A delay in surgical treatment of three months and the number of tendons injured did not affect the outcome. Age affected outcome negatively.Study III) Plasma samples from 17 patients with cuff tears and 16 plasma samples from healthy age- and gender-matched controls were collected and analysed regarding the levels of matrix metalloproteinases and their inhibitors, TIMP1-4. Elevated levels of TIMP-1 were found in the patients with cuff tears compared to controls. Higher levels of TIMP-1, TIMP-3 and MMP-9 were found in patients with full-thickness tears compared to patients with partial-thickness tears.Study IV) Ninety-seven patients with longstanding subacromial pain, on the waiting-list for arthroscopic subacromial decompression, were prospectively randomised to specific shoulder exercises or control exercises for three months. Thereafter they were clinically examined and asked if they still wanted surgery. The specific shoulder exercises focusing on eccentric exercise for the rotator cuff and scapula stabilisers were found to be effective in reducing subacromial pain and improving shoulder function, thereby reducing the need for surgery.Study V) All patients including those operated, in Study IV were re-examined after one year using clinical assessment scores. The option of surgery was continuously available up to the one-year follow-up. Ultrasound and radiological examinations performed at inclusion were analysed in relation to the choice of surgery. The positive effects of the specific exercise programme were maintained after one year and significantly fewer patients in this group chose surgery. Surgery was significantly more often chosen by patients who had a low baseline shoulder score, and/or a full thickness rotator cuff tear. All patients showed significant improvement in the clinical scores one year after inclusion or one year after surgery.These results support the concept that subacromial pain has a multifactorial aetiology and that the first line of treatment should be specific shoulder exercises. When conservative treatment fails, an acceptable result can be achieved with arthroscopic subacromial decompression. The rotator cuff status is important to consider when treating and studying these patients.

- Background and aim: Hip fracture is a leading cause of mortality, morbidity, and disability in older people. The aim of thepresent study was to prospectively assess the development of physical performance in patients with hip fracture after surgery.Setting: Prospective, observational study in a Swedish university hospital.Methods: Assessment of 102 consecutive patients(65 females), with a mean age of 82 years (range 35-98) without specific inclusion or exclusion criteria. Seven physical functionswere assessed using the following 4 measuring methods and 3 rating scales at baseline 7 to 10 days after surgery and follow-upafter 4 months (F4): 10-m habitual walking speed (HWS), timed up and go (TUG), 30-second chair stand test (CST), handgripstrength (HGS), Berg balance scale (BBS), functional ambulation category (FAC), and general mobility.Results: The 47% dropoutpatients were significantly older and more often lived alone or in nursing homes and used indoor walking aids. At baseline, themean HWS was 0.4/0.5 (females/males) m/s; TUG 53/30 s; CST 4/5 kg, and HGS 17.4/31.2 kg. The medians of BBS and FAC were20/20 and 4/4, respectively. There were significant mean improvements at F4 for all 4 measured functions, except for HGS inmales but for neither of the rating scales. There was a large heterogeneity in all assessed variables, both at baseline and regardingchange at 4 months. Therefore, the mean/median results are depicted in figures, showing all individual results at baseline and F4,compared to reference values and discussed in relation to degree of improvement.Conclusion: The observed large heteroge-neity at baseline as well as F4 makes it essentially meaningless to report means and median data of functional assessment ofpatients with hip fracture. There is a strong need for individualization in both health analysis and how the treatment programis targeted, carried through, and evaluated over time in patients with hip fracture

- Aim: To identify groups of hip fracture patients at risk of adverse utcome by investigating interactions between previously reported risk factors.Methods: A consecutive sample of 338 hip fracture patients was included at admission to the orthopaedic department and followed up 4 months later. Outcomes measured were mortality, failure to regain pre-injury mobility and failure to return home. Data were collected about previously reported risk factors for adverse outcomes in those respects.Results: The highest risk of death occured in males living in institutions for the elderly before the fracture (48%). Lowest risk of death had patients admitted from their own home, without malignancy and below 80 years of age (1%). The overall risk of failure to regain pre-injury mobility at the 4 month follow up was 30%. In patients walking independently before the fracture and age above 85 years, the risk increased to 88%. In patients walking with devices before the fracture, the risk of being confined to bed or wheelchair increased from 10% to 20% if the patient was confused. Confusion also increased the risk of relocation from their own home to an institution for the elderly from 19% to 53%.Conclusion: The results of the study can help nurses in making realistic discharge plans based on risk analyses, employing more than just age as risk factor. Using this information nurses can meet the patient’s individual needs in an improved way.

Acute local inflammation elicits sprouting of sensory axons in the rat supraspinatus tendon
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Inflammation activates nociceptive nerve endings and can elicit local sprouting of axons. We hypothesized that axon sprouting might be one factor behind the emergence of painful inflammatory conditions in the shoulder. Here we examine the distribution of sensory and sympathetic axons in the rat subacromial space under normal conditions and after local induction of inflammation with carrageenan. Furthermore, we measured the neuropeptide content in the supraspinatus tendon. In normal rats protein gene product 9.5- (POP 9.5-), substance P- (SP-), calcitonin gene related peptide- (CGRP-), neuropeptide Y- (NPY-) and tyrosine hydroxylase- (TH-) like immunoreactive (LI) axon profiles occurred in the subacromial space and around the glenohumeral joint. In the supraspinatus tendon axon profiles were limited to the tendon-muscle junction. After carrageenan injection inflammatory cells invaded the tendon and the subacromial bursa with a maximum at 2-3 weeks. Moreover, the tendon and the bursa showed signs of sprouting of PGP-9.5-, SP- and CGRP-LI axons, but not NPY- and TH-LI axons. The tendon was also invaded by blood vessels. The occurrence of axon profiles had a maximum at 2 weeks after injection and then subsided. Also, these axons were GAP-43-LI indicating collateral sprouting of nociceptive nerve fibres. There was no significant increase in the concentration of the neuropeptides SP and CGRP in the supraspinatus tendon. No inflammatory reaction or sprouting of nerve fibres was seen in saline-injected controls. We conclude that an acute inflammation in the subacromial space of the rat shoulder region can elicit a transient local sprouting of sensory axons in the tendon stroma and associated aberrant blood vessels.

Increased Occurrence of Nerve Fibres and some Neuropeptides in Subacromial Tissue Biopsies from Patients with Impingement Syndrome of the Shoulder
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: The pathophysiology of subacromial inflammation is not fully understood. In the present study we evaluate the presence of sensory and sympathetic nerve fibres and some neuropeptides in biopsies from the supraspinatus tendon and the subacromial bursa of patients with chronic subacromial inflammation as well as of control cases.Methods: The occurrence of nerve fibres was subjectively assessed by immunohistochemistry. The concentration of substance P (SP), calcitonin generelated peptide (CGRP) and neuropeptide Y (NPY) was measured by radioimmunoassay (RIA).Results: In tendon biopsies from patients with an intact or partially ruptured tendon protein gene product 9.5-like immunoreactive (LI), SP-LI and CGRP-LI nerve fibres were abnormally abundant. In patients with a total tendon rupture nerve fibre occurrence was normal. All biopsies from the bursa exhibited an abnormally high occurrence of SP- and CGRP-LI nerve fibres. In all biopsies the tendon and the bursa contained more blood vessels than normal. The vessels were surrounded by NPY- and tyrosine hydroxylase-LI nerve fibres in a subjectively normal pattern. RIA analysis revealed that the concentration of all three neuropeptides was abnormally high in tendon biopsies from patients with an intact or partially ruptured tendon. Tendon biopsies from patients with total tendon rupture showed statistically normal levels. Biopsies from the bursa showed abnormally high levels of SP and CGRP but normal levels of NPY in all patients.Conclusion: We conclude, that the supraspinatus tendon and the subacromial bursa exhibit an increased occurrence of nerve fibres and some neuropeptides in patients with chronic subacromial inflammation.Clinical relevance: Patients with chronic subacromial inflammation have a disabling pain problem. The increased local occurrence of sensory andsympathetic axons in the inflamed tissues as well as the elevated tissue concentration of certain neuropeptides may represent important factors behind that problem.

- The purpose of the study was to evaluate the clinical effect of ketoprofen after arthroscopic subacromial decompression (ASD). The design was randomized, prospective, and double-blind, with a placebo control group. Forty-one consecutive patients with subacromial impingement syndrome, were randomized to treatment with ketoprofen 200 mg once daily or placebo for 6 weeks following ASD. For additional analgesia, patients used paracetamol if necessary. Clinical follow-up was performed at 6 weeks and at 2 years postoperatively. At the 6-week follow-up, the patients treated with ketoprofen had a statistically significant increase in UCLA total score (P < .05), range of movement (P < .05), and satisfaction (P < .05), and they had significantly less pain (P < .05). There was no statistical difference between the ketoprofen and placebo groups regarding strength. Patients receiving ketoprofen had significantly less need for additional analgesia (P < .05). At the 2-year follow-up, there were no differences in the scores between the ketoprofen and placebo group.

Tidskriftsartikel (refereegranskat)abstract
- In the literature operative management of rotator cuff ruptures in the shoulder varies, from tendon repair to debridement of the cuff lesion combined with subacromial decompression. This study was made to evaluate whether patients with intact rotator cuff differed from patients with rotator cuff ruptures regarding functional outcome after arthroscopic subacromial decompression. We performed a clinical review of 39 patients with subacromial impingement who all underwent arthroscopic subacromial decompression; no other surgery was performed. There were 13 patients with intact cuff, 13 patients with partial-thickness supraspinatus ruptures, and 13 patients with full-thickness supraspinatus ruptures <2 cm. Selection was based solely on the status of the supraspinatus tendon. Patients with other pathologic conditions were excluded. Follow-up was performed after 3 and 6 years. The clinical evaluation was performed with the Constant score and the visual analog pain score. The 3- and 6-year follow-up (100% follow-up rate) revealed no significant difference between the groups regarding the Constant scores and the visual analog scale values. Also, no significant difference was seen among the 3 groups in active range of motion or strength, and the patients had no appreciable pain. We conclude that the functional outcome 6 years after arthroscopic subacromial decompression is not obviously related to the preoperative degree of cuff pathology, even if a total rupture of small size is present.

Intermittent versus indwelling urinary catheterisation in hip surgery patients : a randomised controlled trial with cost-effectiveness analysis
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: Hip surgery is associated with a risk for postoperative urinary retention. To avoid urinary retention hip surgery patients undergo urinary catheterisation. Urinary catheterisation, however, is associated with increased risk for urinary tract infection (UTI). Presently, there is limited knowledge whether intermittent or indwelling urinary catheterisation is the preferred choice for short-term bladder drainage in patients undergoing hip surgery.Objectives: The aim of the study was to investigate differences between intermittent and indwelling urinary catheterisation in hip surgery patients in relation to nosocomial UTI and cost-effectiveness.Design: Randomised controlled trial with cost-effectiveness analysis. Setting: The study was carried out at an orthopaedic department at a Swedish university hospital.Method: One hundred seventy hip surgery patients (patients with fractures or with osteoarthritis) were randomly allocated to either intermittent or indwelling urinary catheterisation. Data collection took place at four time points: during stay in hospital, at discharge and at 4 weeks and 4 months after discharge. Results: Eighteen patients contracted nosocomial UTIs, 8 in the intermittent catheterisation group and 10 in the indwelling catheterisation group (p = 0.618). The patients in the intermittent catheterisation group were more often catheterised (p <0.001) and required more bladder scans (p <0.001) but regained normal bladder function sooner than the patients in the indwelling catheterisation group (p <0.001). Fourteen percent of the patients in the intermittent group did not need any catheterisation. Cost-effectiveness was similar between the indwelling and intermittent urinary catheterisation methods.Conclusions: In the perspective of cost-effectiveness both indwelling and intermittent methods could be appropriate in clinical praxis. Both methods have advantages and disadvantages but by not using indwelling catheterisation routinely in this patient group unnecessary catheterisations might be avoided.

Tidskriftsartikel (refereegranskat)abstract
- Background: The pathophysiology of chronic supraspinatus tendinitis is not fully understood. This may be due to the scarcity of experimental studies on this issue.Methods: In search for a system suitable for experimental analysis, the present study describes the relevant gross anatomy of the rat shoulder region (dissection), and examines the fiber composition of relevant suprascapular nerve branches (electron microscopy, selective denervations).Results: The rat shoulder region is similar to the human shoulder in terms of gross anatomy. The average suprascapular nerve (SSC) is derived mainly from the spinal cord segment C5 and contains 3,435 axons, 74% of which are unmyelinated. The supraspinatus branch (SSP) contains 627 fibers. Of the SSP fibers, 52% are myelinated, including 32% motor and 20% sensory axons. Of the C-fibers in the SSP 16% are sympathetic efferents and 32% are sensory. Many of the latter disappear after neonatal capsaicin treatment. The SSC emits a subacromial articular branch (ART), with some 260 axons, about 90% of which are unmyelinated. The myelinated ART fibers are sensory, and of the unmyelinated ones about 24% are sympathetic efferents and 66% are afferents. The latter resist neonatal capsaicin treatment.Conclusions: In view of the anatomy of the supraspinatus muscle, of the subacromial space, and of relevant nerves, the rat shoulder should be appropriate for experimental studies on inflammatory conditions in the subacromial space.

Tidskriftsartikel (refereegranskat)abstract
- A consecutive series of 181 patients with clinical signs of subacromial impingement underwent arthroscopic subacromial decompression (ASD). All patients had the same surgical procedure, and all pathological findings at the arthroscopy were recorded. Ten to 13 years (mean, 11.2) after the procedure, 162 patients (91%) were available for follow-up consisting of clinical examination and the Constant-Murley and DASH scores. The overall mean value of the age correlated Constant score was 77 points. Men had significantly better Constant score than women. The state of the rotator cuff at the index procedure was found to affect the outcome significantly. Patients with isolated full-thickness supraspinatus tears had the best results, followed by those with partial tears, intact cuffs, or large tears involving more than 1 tendon. ASD in the treatment of subacromial impingement yields good long-term results. Small full-thickness supraspinatus tears had the best results, indicating that the ASD might prevent further cuff deterioration and that repair of these lesions may be unnecessary.

Tidskriftsartikel (refereegranskat)abstract
- Sever's injury (apophysitis calcanei) is considered to be the dominant cause of heel pain among children between 8 and 15 years. Treating Sever's injury with insoles is often proposed as a part of a traditional mix of recommendations. Using a custom-molded rigid heel cup with a brim enclosing the heel pad resulted in effective pain relief without reducing the physical activity level in our previous two studies. The purpose of this study was to assess the effect of the heel cup on heel pad thickness and heel peak pressure (n=50). The difference in heel pad thickness and in heel peak pressure using a sports shoe without and with a heel cup was compared. With the heel cup the heel pad thickness improved significantly and the heel peak pressure was significantly reduced. These effects correlated with a significant reduction in pain when using the heel cup in a sports shoe, compared with using a sports shoe without the heel cup. A heel cup, providing an effective heel pad support in the sports shoe, improved the heel pad thickness and reduced heel peak pressure in Sever's injury with corresponding pain relief.

Tidskriftsartikel (refereegranskat)abstract
- Sever's injury (apophysitis calcanei) is considered to be the dominant cause of heel pain among children between 8 and 15 years. The traditional advice is to reduce and modify the level of physical activity. Recommended treatment in general is the same as for adults with Achilles tendon pain. The purpose of the study was to find out if insoles, of two different types, were effective in relieving heel pain in a group of boys (n = 38) attending a Sports Medicine Clinic for heel pain diagnosed as Sever's injury. The type of insole was randomized, and self-assessed pain during physical activity in the treatment phase with insoles was compared with pain in the corresponding pre- and post-treatment phases without insoles. There were no other treatments added and the recommendations were to stay on the same activity level. All patients maintained their high level of physical activity throughout the study period. Significant pain reduction during physical activity when using insoles was found. Application of two different types of insoles without any immobilization, other treatment, or modification of sport activities results in significant pain relief in boys with Sever's injury.

- Sever's injury (apophysitis calcanei) is considered to be the dominant cause of heel pain among children. Common advice is to reduce physical activity. However, our previous study showed that application of insoles reduced pain in Sever's injury without having to reduce physical activity. The purpose of this study was to test which of the two insoles, the heel wedge or the heel cup, provided best pain relief during sport activity in boys with Sever's injury (n = 51). There was a crossover design in the first randomized part of the study. In the second part, the boys, 9-14 years, chose which insole they preferred. There was a reduction in odds score for pain to a fifth (a reduction of 80%) for the cup compared with the wedge (P<0.001). When an active choice was made, the heel cup was preferred by >75% of the boys. All boys maintained their high level of physical activity throughout. At 1-year follow-up, 22 boys still used an insole and 19 of them reported its effect on pain as excellent or good (n = 41).

- Background: Long-term results regarding tear progression, arthropathy, and clinical scores of unrepaired rotator cuff tears are largely unknown. This study investigated whether the condition of the glenohumeral joint and rotator cuff had deteriorated at a minimum of 20 years after an acromioplasty without cuff repair and assessed the clinical results. Methods: A retrospective analysis was conducted of a consecutive series of patients treated between 1989 and 1993 with acromioplasty without cuff repair due to subacromial pain and cuff tear. At follow-up results of x-ray, ultrasonography, and clinical scores were recorded. Results: At a mean of 22 years (range, 21-25 years), 69 patients were available for follow-up with Western Ontario Rotator Cuff Index, Constant-Murley (CM) score, x-ray, and ultrasonography. Mean age at operation was 49 years (range, 19-69 years). There were 45 partial-thickness tears (PTT) and 24 full-thickness tears (FTT). Of 23 patients with FTT, 17 (74% with x-ray) had developed cuff tear arthropathy (Hamada amp;gt;= 2) and 20 (87% with ultrasonography) had progressed in tear size. Mean relative CM in patients with FTT and cuff tear arthropathy was 62 (standard deviation [SD], 27), and the mean WORC was 58% (SD, 26%). In the 43 PTT patients, 3 (7% with x-ray) had developed cuff tear arthropathy and 16 (42% with ultrasonography) had tear progression. With PTT at follow-up, the mean relative CM was 101 (SD, 22), and the mean WORC was 81% (SD, 20%). Conclusions: After an acromioplasty, most unrepaired full-thickness tears will, in long-term, increase in size and be accompanied by cuff tear arthropathy changes. Most partial thickness tears remain unchanged; cuff tear arthropathy is rare, and clinical scores generally good. (C) 2016 Journal of Shoulder and Elbow Surgery Board of Trustees.

- BackgroundTreatment options for irreparable cuff tears include synthetic interposition grafts, but whether such grafts can maintain acceptable shoulder function and prevent cuff tear arthropathy in the long-term is unknown.MethodThis was a retrospective case series of 13 consecutive patients treated with a synthetic interposition graft made of Dacron (DuPont, Wilmington, DE, USA). Patients were examined with bilateral ultrasonography, bilateral x-ray imaging, Constant-Murley score, and Western Ontario Rotator Cuff score.ResultsAfter a mean of 18 years (range, 17-20 years), 1 patient had died, and 12 were available for x-ray imaging and 10 also for ultrasonography and clinical scores. Cuff tear arthropathy (Hamada grade ≥2) had developed in 9 of 12 (75%; 95% confidence interval, 43%-95%), including 3 patients operated on with arthroplastyin the follow-up period. The mean absolute Constant-Murley score was 46 (standard deviation, 26), and the mean Western Ontario Rotator Cuff score was 59 (standard deviation, 20). In 7 of 10 patients (70%) with available ultrasonography, the graft was interpreted as not intact. All patients had a contralateral full-thickness tear, and 7 of 12 patients (58 %; 95% confidence interval, 28%-85%) had contralateral cuff tear arthropathy. The number of patients with cuff tear arthropathy was not significantly different between the shoulder repaired with a Dacron graft and the contralateral shoulder (P = .667).ConclusionThese results indicate that a synthetic interposition graft with screw fixation could not prevent cuff tear arthropathy and preserve cuff integrity in a long-term perspective.

Rotator Cuff Tears : Short- and long-term aspects on treatment outcome
- 2020

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Rotator cuff tear is a common disorder and there is a lack of knowledge of appropriate treatment and consequences of different treatment modalities. The overall aim of this thesis was to examine short- and long-term results of rotator cuff tear treatment.In Paper I we did a retrospective 21 to 25-year follow-up of a consecutive series of patients with partial and full-thickness rotator cuff tears, treated with acromioplasty without cuff repair. The cuff status had been documented in a specific perioperative protocol in all patients at the index operation. We did x-ray, ultrasonography and clinical scores with Constant score and Western Ontario Rotator Cuff index (WORC) at follow-up. We identified 111 patients with either a partial or a full-thickness tear, but at follow-up 21 were deceased and 11 were too ill from medical conditions unrelated to their shoulder. Out of the remaining 78 eligible patients, 69 were examined (follow-up rate 88 %) and they had a mean age at the index operation of 49 years (range 19-69 years). Forty-five had a partial tear and 24 a full-thickness tear at the index operation. At follow-up, 74% of patients with full-thickness tear had cuff tear arthropathy grade 2 or more according to the arthropathy classification of Hamada (grade 1 to 5) and 87% had developed tear progression (i.e. a larger tear). Corresponding numbers in those with a partial tear was 7 % arthropathy and 42 % tear progression, and the differences between the full-thickness group and the partial tear group was significant for both outcome measures (P<0.001 for both analyses). In those with arthropathy, the mean Constant score was 47 (standard deviation [SD], 23), the mean age and gender-adjusted Constant score 62 (SD, 27) and the mean WORC 58 % (SD, 26). Patients with a partial tear at follow-up had mean Constant score and WORC within the normal range. In multivariable analysis with logistic regression, having a full-thickness tear at the index operation was a risk factor for arthropathy (odds ratio [OR] 37.8; 95% confidence interval [CI], 8.2-175.0) and for tear progression (OR 6.09; 95% CI, 1.41-26.29).In Paper II we examined the contralateral shoulder in the same patients as in paper I and with the same methodology. Sixty-one patients were examined and 38 had had a partial tear at the index operation 21-25 years ago and 23 a full-thickness tear. The overall rate of contralateral full-thickness tears was 50.8 %, which is higher than the 16-35 % rate found in previous studies of newly diagnosed cuff patients. The rate of contralateral full-thickness tear ranged from 13.6 % in patients with a partial tear in the index shoulder at follow-up, to 90 % in patients with a full-thickness tear and arthropathy in the index shoulder. There was a significant correlation regarding conditions between shoulders in the same patient, with a Spearman coefficient of 0.72 for the number of ten-dons with a full-thickness tear, 0.31 for Hamada grade of arthropathy and 0.65 for Constant score. The number of tendons with a full-thickness tear in the index shoulder at follow-up was a risk factor for a contralateral full-thickness tear (OR 3.28; 95% CI, 1.67-6.44) in a multi-variable logistic regression model. We also found that cuff tear arthropathy was significantly more common in patients who had undergone an acromioplasty (P<0.001), a finding which is not confirmatory but may generate a hypothesis.Paper III addressed 17 to 20-year results after operation with a synthetic interposition graft for irreparable cuff tears. We used X-ray, ultrasonography and clinical scores at follow-up. We identified a consecutive series of 13 patients, one of whom was deceased at follow-up. Ten of the remaining 12 participated in a complete follow-up and 2 did only x-ray examination. Nine out of 12 (75 %; 95% CI, 43-95 %) had cuff tear arthropathy Hamada grade 2 or more in the index shoulder at follow-up. The mean Constant score was 46 (SD, 26) and the mean WORC 59 % (SD, 20). Seven out of 12 had contralateral cuff tear arthropathy, and the difference in frequency of arthropathy between shoulders was not statistically significant (P=0.667).In Paper IV we tested whether early repair of small cuff tears, involving mainly supraspinatus, would give a superior clinical result com-pared to physiotherapy without repair in a prospective randomised trial with 12 months follow-up. We used Constant score as the primary out-come, and WORC, EQ-VAS and Numerical Rating Scale for pain (NRS) as secondary outcomes. We also aimed at assessing the rate of tear progression in unrepaired shoulders and the healing rate in repaired shoulders by Magnetic Resonance Imaging (MRI) performed at 12 months. With a high grade of follow-up (100 % for 12 months Constant score and 95 % for 12 months MRI), the repair group had a 12 months median Constant score of 83 (Quartile range [QR], 25) and the conservative group 78 (QR, 22). This between-group difference in medians of 4.5 (95% CI,-5 to 9; P=0.68) was not statistically significant and we did not detect any significant differences in the secondary outcomes at 12 months. The retear rate was 6.5 % in repaired patients and 29 % of unrepaired patients had a tear enlargement >5 mm.The results in this thesis indicate that patients with small, traumatic, full-thickness tears of mainly supraspinatus have no clinical benefit of early surgical repair compared to physiotherapy alone, but in the long-term, patients with full-thickness tears have an increased risk of tear progression, cuff tear arthropathy and low clinical scores. These results are especially important in the treatment decision of repair or not in younger patients. Having a full-thickness tear is also a risk factor for having a contralateral cuff tear, a phenomenon that underlines the importance of endogenous factors in the development of rotator cuff tears. If a cuff tear is not repairable to bone, the addition of a synthetic inter-position graft does not seem to prevent cuff tear arthropathy.

- The purpose of this study was to investigate the incidence and prevalence of injuries among elite weight lifters and power lifters, with a special focus on shoulder injuries and possible injury-provoking exercises. In 1995, a questionnaire was administered to 110 male and female elite lifters to evaluate injuries and training characteristics. A follow-up of the athletes from 1995 was conducted in 2000, and a new 2000 elite group was also queried. In 1995 and again in 2000, the athletes sustained, on average, 2.6 injuries per 1000 hours of activity. Most common in 1995 were low back injuries, with an injury rate of 0.43 per 1000 hours, and shoulder injuries, with a rate of 0.42 per 1000 hours. Shoulder injuries dominated in 2000, with an injury rate of 0.51 per 1000 hours of activity. There was a difference in injury pattern between weight lifters, who mostly sustained low back and knee injuries, and power lifters, in whom shoulder injuries were most common. No correlation was found between shoulder injuries and any specific exercise. Although the total injury rate was the same during the two periods of study, the rate of shoulder injuries had increased.

Carrageenan-induced subacromial bursitis caused changes in the rat's rotator cuff
- 2001

Tidskriftsartikel (refereegranskat)abstract
- This study was designed to investigate the histologic expression of the rat's supra- and infraspinatus tendons in carrageenan-induced subacromial bursitis. Thirty-two rats received subacromial injections with carrageenan (n = 28) or saline (n = 4). The tendons were analysed microscopically after staining with hematoxyline eosin, Van Giesons hematoxyline and immunofluorescent staining of fibronectin and fibrinogen. In the controls (saline × 10) and group A (carrageenan × 5) there were no changes in the tendons. In group B (carrageenan × 10) 3/8 rats showed macrophages between the collagen fibres and an increased staining of fibronectin. In group C (double dosis carrageenan) all rats had signs of fibrocartilaginous metaplasia in the supraspinatus tendon. In eight of these specimens even bony metaplasia was seen. The infraspinatus tendon showed fibrosis but no fibro-cartilaginous metaplasia. The results showed that iatrogenic bursitis after carrageenan subacromial injections was associated with marked changes of the supraspinatus tendon.

Tidskriftsartikel (refereegranskat)abstract
- Fifty patients were reviewed after arthroscopic subacromial decompression. Twenty-five had calcific deposits in the rotator cuff visible on x-ray evaluation. Each patient with calcification was matched with a patient without calcification who had a similar state of the rotator cuff, date of surgery, age, and sex. The calcific deposits were left untouched in all cases. No significant difference was found in the postoperative outcome between the patients in the two groups measured by the Constant score. Before surgery 7 (28%) patients had calcifications of < 5 mm, and 18 (72%) patients had calcifications that were > or = 5 mm. At a 2-year follow-up (n = 24) these figures were 20 (83%) and 4 (17%), respectively (p < 0.001). Postoperative x-ray evaluations revealed a disappearance or decrease in size of the calcific deposits in 19 (79%) of the patients. These results provide new information on the course of calcifying tendinitis, which may indicate that we can leave calcific deposits untouched within the rotator cuff when performing arthroscopic subacromial decompression.

- The aim of this study was to evaluate the effects of repeated steroid injections into the subacromial space. Thirty rats were injected either 3 or 5 times with triamcinolone in a dosage equivalent to that given to human beings or 3 or 5 times with saline into the subacromial space. One rat received no injection. The supraspinatus and infraspinatus tendons were evaluated macroscopically and microscopically. Two different staining methods were used on each sample including hematoxylin eosin and Miller's elastin/van Gieson's solution. After 5 steroid injections, we found focal inflammation, necrosis, and fragmentation of collagen bundles in the tendon in 4 of 7 rats. The tendons of the controls showed a normal structure (P < .05). There were no pathologic changes among the rats that were injected with triamcinolone 3 times. These results show that repeated subacromial injections of triamcinolone may cause damage to the rotator cuff of the rat. This finding may indicate cautious use of subacromial steroid injections in human beings.

- This study was designed to investigate human surgical specimens from patients with impingement (n = 16), ruptured supraspinatus tendons (n = 7), frozen shoulder (n = 2) and controls (n = 9) with respect to histological changes and the presence of fibronectin and Matrix metalloprotease-1 (MMP-1). The biopsy of the middle part of the supraspinatus tendons was analyzed microscopically after staining with hematoxyline eosin, Van Giesons hematoxyline and Phospho Tungstic Acid Hematoxyline for visualization of fibrin. Immunofluorescent stainings for fibronectin and MMP-1 were performed. Histology and immunofluorescence were assessed blindly. Necrotic tendinous tissue and fibrin were found only in some specimens from ruptures. The staining for fibronectin was significantly increased among patients with a rupture. MMP-1 was, however, only infrequently found in specimens from patients with impingement and ruptures. Fibrosis and thinning of fascicles seemed to be a more non-specific finding, appearing in control, impingement and rupture specimens. In conclusion, necrotic tendinous tissue, fibrin and fibronectin appear to be signs of tendon degeneration, whereas fibrosis and thinning of fascicles were found also in controls. © 2002 Orthopaedic Research Society.

- Assessing laxity of the shoulder joint in patients who are under anesthesia is a standard procedure before arthroscopy. The aim of this study was to evaluate a novel instrument for quick and reliable intraoperative measurement of glenohumeral translation. Previous testing of various designs has resulted in a device secured by 1 pin in the acromion and 1 pin in the proximal humerus. These pins are interconnected by a sliding ruler that gives translation values in millimeter increments as the laxity tests are performed. Comparison between manual arbitrary approximation of laxity and instrumented translation measurements showed that manual testing is reasonably good for assessment of anterior and posterior translation, without, however, providing values of translation in millimeter increments. The low correlation between manual assessment and instrumented inferior translation measurements indicates that inferior translation is more difficult to approximate manually. The shoulder translation tester was used in 102 patients. The mean values for clinically stable shoulders (n = 58) were 5 mm for anterior translation, 5 mm for posterior translation, and 4 mm for inferior translation. The corresponding values in unstable shoulders were significantly higher than in the stable shoulders, especially in patients with multidirectional instability. We conclude that the shoulder translation tester is easy and quick to use. It provides quantitative values of translation and will thus contribute information for correct diagnosis, therapy, and documentation.

- Purpose: The purpose of this study was 2-fold: to document the accuracy of a new measuring device and to intraoperatively compare the subacromial distance between controls and patients with impingement syndrome before and after arthroscopic subacromial decompression (ASD). Type of Study: Clinical study. Methods: When performing an ASD, it is important that bone resection is adequate. Today the correct subacromial distance after bone resection is only assessed by eye, directly or indirectly. The subacromial distance was measured between the anterolateral corner of the acromion and the supraspinatus tendon in the lateral decubitus position. The device was inserted 2 to 3 cm below the anterolateral acromion. There was no subacromial pathology among the controls (n = 15, mean age, 28 years). In 30 patients with impingement syndrome (average age, 53 years) an ASD was performed. The subacromial distance was measured after bursectomy and then after bone resection. Intraindividual and interindividual assessment was performed. Results: The mean value of the subacromial distance in controls was 16 mm, the 95% confidence limits between 14 and 18 mm. The mean value in the group of patients with impingement syndrome was 8 mm before and 16 mm after the decompression. Due to the pressure within the subacromial space, the subacromial distance increased 1 mm. Intraindividual measurements never varied more than 1 mm (n = 5). The correlation coefficient between the measurements by both authors was 0.99. Conclusions: In this study, we assessed and described the use of a measuring device that enables the surgeon to quantify the subacromial distance before and after bone resection. After bone resection, the mean value of the subacromial distance was well within the control values. The amount of bone resected varied from 5 to 13 mm. This new device enables documentation in clinical work as well as in research.

The Supraspinatus Tendon : Clinical and histopathological aspects
- 2001

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The supraspinatus tendon is an important structure of the rotator cuff. Subacromial impingement is a common reason for shoulder pain. Despite extensive scientific work in this field, the cause of impingement syndrome is still not fully understood. The general aim of the present thesis was to generate new knowledge with respect to pathogenesis and treatment of impingement syndrome. A combination of animal and clinical studies were performed. Different methods were used such as histology, immunohistochemistry, development and assessment of a novel measuring device and clinical and radiological assessment.Thirty rats were injected with triamcinolone or saline into the subacromial bursa. After five corticosteroid injections, we found focal inflammation, degradation and fragmentation of collagen bundles in the supraspinatus tendon, whereas the control specimens were normal (p=0.035).Subacromial bursitis was induced by injections of carrageenan into the subacromial space (n=28). Fibrocartilaginous metaplasia and bony metaplasia were found in the supraspinatus tendon. Even in specimens with no histologic changes of the collagen bundles the staining for fibronectin was significantly increased.The distance between the anterolateral acromion and the supraspinatus tendon was measured in patients with impingement syndrome intraoperatively (n=30) and in controls (instability, n=15). The mean value of the subacromial distance in controls was 16 mm, the 95% mean confidence limits between 14 and 18 mm. The mean value in the group of patients with impingement syndrome was 8 mm before and 16 mm after the decompression.Fifty patients were reviewed after arthroscopic subacromial decompression. Twenty-five showed calcific deposits in the rotator cuff on radiographs preoperatively. In 13 patients the calcific deposits totally disappeared postoperatively. In another six patients the calcifications had decreased in size. Four patients still showed calcifications, which were 5 mm or greater in size. The postoperative results measured by the Constant score were almost identical in the calcific and the non-calcific groups. Tillander 010916 8 Human surgical supraspinatus tendon specimens were studied from patients with impingement (n=16), ruptured supraspinatus tendons (n=7) and controls (n=10). Degradation of tendinous tissue and fibrin were found only in some specimens from ruptures. The difference in fibronectin staining was significant between controls and patients with a rupture (p=0.002). Fibrosis and thinning of fascicles seemed to be a more non-specific finding, appearing in control, impingement and rupture specimens.In conclusion, subacromial corticosteroid injections may cause rupture of the supraspinatus tendon. Metaplasia of the supraspinatus tendon may play a role in the pathogenesis of impingement and rupture of the supraspinatus tendon. The subacromial distance can be measured intraoperatively and was shown to be lower in patients with impingement than in patients with instability. Calcifications disappear or decrease in size after arthroscopic subacromial decompression and do not seem to influence the postoperative outcome in patients with impingement. Degradation of tendon tissue, fibrin and fibronectin appear to be signs of tendon degeneration, whereas fibrosis and thinning of fascicles were found also in controls.

- INTRODUCTION: Pain management in patients with hip fractures is a major challenge for emergency care. The objective of this study was to evaluate whether the supplementation of pre-operative analgesia with low-dose fascia iliaca compartment block (FICB) compared with placebo would improve pain relief in patients with hip fractures.METHODS: A double-blind, randomized, controlled trial was conducted on 127 patients. At hospital admission, a low-dose FICB was administered to patients with hip fractures as a supplement to regular pre-operative analgesia. Patients with and without cognitive impairment were included. The instruments used were a visual analogue scale (VAS), a numerical rating scale and a tool for behavior related pain assessment. The primary endpoint was the change in reported pain on movement from hospital admission to two hours after FICB.RESULTS: The intervention group showed improved pain management by mean VAS score for pain on movement compared with the control group (p = 0.002).CONCLUSIONS: Our results support the use of low-dose FICB as a pain-relieving adjuvant to other analgesics when administered to patients with a hip fracture.

- 33 rheumatoid patients, treated with hemispherical cup resurfacing hemiarthroplasty of the shoulder without medullary fixation (6 bilaterally), were reviewed after mean 4.4 (2-6) years. The median Constant score was 30 (15-79), mean proximal migration of the humerus 5.5 (SD 5.2) mm and mean glenoid erosion 2.6 (SD 1.7) mm. Proximal migration and glenoid erosion did not correlate with shoulder function or pain. Radiographic signs of loosening (changes in cup inclination combined with changes in cup distance above the greater tuberosity) occurred in one quarter of the shoulders. At follow-up, 26 patients were satisfied with the procedure, despite poor shoulder function and radiographic deterioration.
