- BackgroundThe purpose of this study is to determine the prevalence and morbidity of neck pain with or without cervical rhizopathy, upper extremity motor deficit and/or thoracolumbar pain in elderly men.MethodsWe conducted a cross-sectional questionnaire study of 3,000 community-dwelling older men with a mean age of 75.4 +/- 3.2 years (range 69-81) to determine if they had experienced neck pain with or without cervical rhizopathy/upper extremity motor deficit/thoracolumbar pain (yes/no) during the preceding 12 months, and if so, morbidity with the condition (no/minor/moderate/severe).ResultsAmong the participants, 865 (29%) reported they had experienced neck and 1,619 (54%) thoracolumbar pain. Among the men with neck pain, 59% had experienced only neck pain, 17% neck pain and cervical rhizopathy and 24% neck pain, rhizopathy and motor deficit. For men with only neck pain, the morbidity was severe in 13%, for men with neck pain and rhizopathy it was 24%, and for men with pain, rhizopathy and motor deficit it was 46% (p < 0.001). Among the men with neck pain, 23% had experienced only neck pain and no thoracolumbar pain; the remaining 77% had both neck and thoracolumbar pain. The morbidity was severe in 10% of the men with neck pain but no thoracolumbar pain and 30% in men with neck and thoracolumbar pain (p < 0.001).ConclusionNeck pain in elderly men is common but symptoms and morbidity vary. For men who only have neck pain, 1/8 rated their morbidity as severe, while almost half who also had cervical rhizopathy and motor deficit and almost 1/3 of those who also had thoracolumbar pain reported severe morbidity.

- A trend within the orthopedic community is rejection of the belief that "one size fits all." Freddie Fu, among others, strived to individualize the treatment of anterior cruciate ligament (ACL) injuries based on the patient's anatomy. Further, during the last two decades, greater emphasis has been placed on improving the outcomes of ACL reconstruction (ACL-R). Accordingly, anatomic tunnel placement is paramount in preventing graft impingement and restoring knee kinematics. Additionally, identification and management of concomitant knee injuries help to re-establish knee kinematics and prevent lower outcomes and registry studies continue to determine which graft yields the best outcomes. The utilization of registry studies has provided several large-scale epidemiologic studies that have bolstered outcomes data, such as avoiding allografts in pediatric populations and incorporating extra-articular stabilizing procedures in younger athletes to prevent re-rupture. In describing the anatomic and biomechanical understanding of the ACL and the resulting improvements in terms of surgical reconstruction, the purpose of this article is to illustrate how basic science advancements have directly led to improvements in clinical outcomes for ACL-injured patients.

- Background: With aging of the population, the numbers of osteoporotic vertebral fractures with intravertebral cleft have been increasing. However, the details of clinical symptoms of osteoporotic vertebral fractures with intravertebral cleft are poorly understood. The purpose of this study was to evaluate the relationship between clinical symptoms of osteoporotic vertebral fractures with intravertebral cleft and radiographic findings. Methods: Two hundred seventeen patients with single-level osteoporotic vertebral fractures with intravertebral cleft were examined. Clinical symptoms were evaluated using Numerical Rating Scale for back pain and the Oswestry Disability Index for physical disability. The presence of delayed neurologic deficit was also detected. Radiography and computed tomography were used to measure local kyphotic angle and vertebral instability and to detect the presence of posterior wall fracture of the vertebral body. Correlations between clinical symptoms of osteoporotic vertebral fractures with intravertebral cleft and radiographic findings were investigated. Results: Mean Numerical Rating Scale and Oswestry Disability Index were 7.4 and 58.0%, respectively. Delayed neurologic deficit occurred in 41 patients (19%). The mean local kyphotic angle, vertebral instability, and rate of posterior wall fracture of the vertebral body were 19.4 degrees, 7.3 degrees, and 91%, respectively. Numerical Rating Scale and Oswestry Disability Index were statistically correlated with vertebral instability but not with local kyphotic angle and presence of posterior wall fracture. In the patients with delayed neurologic deficit, vertebral instability was significantly higher and posterior wall fractures were significantly more frequent than in the patients without delayed neurologic deficit. Local kyphotic angle was not correlated with delayed neurologic deficit. Conclusions: Vertebral instability is a factor causing symptoms of osteoporotic vertebral fractures with intravertebral cleft. In addition, vertebral instability may be the predominant cause of delayed neurologic deficit. To manage osteoporotic vertebral fractures with intravertebral cleft and delayed neurologic deficit efficiently, it may be important to control vertebral instability of osteoporotic vertebral fractures.

- Internationally adopted children (IAC) with a cleft lip and/or palate (CL/P) tend to arrive with un-operated palates at an age at which their Swedish-born peers have completed their primary palate surgery. Our aim of the present study was to analyze surgical, speech and hearing outcomes of IAC at age 5 and compare with those of a matched group of Swedish-born children. Fifty children with CL/P born in 1994-2005 participated in the study. Twenty-five IAC were matched according to age, sex and cleft type with 25 Swedish-born children. Audio recordings were perceptually analyzed by two experienced, blinded speech-language pathologists. Hearing and speech statuses were evaluated on the same day for all children. Surgical timing and complications as in fistulas and requirement for secondary velopharyngeal (VP) surgery, speech evaluation results, and present hearing status were analyzed for all children of age 5 years. Results showed that primary palatal surgery was delayed by a mean of 21 months in IAC. IAC had a higher prevalence of velopharyngeal impairment that was statistically significant, a higher fistula rate, and experienced more secondary surgery than Swedish-born peers. Hearing loss due to middle ear disease was slightly more common among IAC, whereas the rate of treatment with tympanostomy tubes was similar between the two groups. In conclusion, IAC with CL/P represent a challenge for CL/P teams because of the heterogeneous nature of the patient group and difficulties associated with delayed treatment, and the results show the importance of close follow-up over time.

IL-17 cytokines in bone healing of diabetic Charcot arthropathy patients: a prospective 2 year follow-up study
- 2015
-
Ingår i: Journal of Foot and Ankle Research. - : Springer Science and Business Media LLC. - 1757-1146. ; 8
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Little is currently known of the pathophysiological mechanisms triggering Charcot arthropathy and regulating its recovery although foot trauma has been proposed as a major initiating factor by activation of proinflammatory cytokines leading to increased osteoclastogenic activity and progressive bone destruction. Several members of the IL-17 family of proinflammatory cytokines have been shown to play a key role in the pathogenesis of inflammatory conditions affecting bone and joints but none has previously been studied in Charcot foot patients. The aim of this study was to investigate the role of IL-17A, IL-17E and IL-17F in patients presenting with Charcot foot. Methods: Twenty-six consecutive Charcot patients were monitored during 2 years by repeated foot radiographs, MRI and circulating levels of IL-17A, IL-17E and IL-17F. Analysis of cytokines was done by ultra-sensitive chemiluminescence technique and data were analyzed by one-way repeated measures ANOVA. Neuropathic diabetic patients (n = 20) and healthy subjects (n = 20) served as controls. Results: Plasma IL-17A and IL-17E in weight-bearing Charcot patients at diagnosis were at the level of diabetic controls, whereas IL-17F was significantly lower than diabetic controls. A significant increase in IL-17A and IL-17E reaching a peak 2-4 months after inclusion and start of offloading treatment in Charcot patients was followed by a gradual decrease to the level of diabetic controls at 2 years postinclusion. In contrast, IL-17F increased gradually from inclusion to a level not significantly different from diabetic controls after 2 years. Conclusions: Charcot patients display a significant elevation of all three IL-17 cytokines during the follow-up period relative values at diagnosis and values in control patients supporting a role in the bone repair and remodeling activity during the recovery phase. The rapid increase of IL-17A and IL-17E shortly after initiating off-loading treatment could suggest this to be a response to immobilization and stabilization of the diseased foot.

- Correct classification of fractures according to their patterns is critical for developing a treatment plan in orthopaedic surgery. Unfortunately, for proximal humeral fractures (PHF), methods for proper classification have remained a jigsaw puzzle that has not yet been fully solved despite numerous proposed classifications and diagnostic methods. Recently, many studies have suggested that three-dimensional printed models (3DPM) can improve the interobserver agreement on PHF classifications. Moreover, Virtual Reality (VR) has not been properly studied for classification of shoulder injuries. The current study investigates the PHF classification accuracy relative to an expert committee when using either 3DPM or equivalent models displayed in VR among 36 orthopaedic surgery residents from different hospitals. We designed a multicentric randomised controlled trial in which we created two groups: a group exposed to a total of 34 3DPM and another exposed to VR equivalents. Association between classification accuracy and group assignment (VR/3DPM) was assessed using mixed effects logistic regression models. The results showed VR can be considered a non-inferior technology for classifying PHF when compared to 3DPM. Moreover, VR may be preferable when considering possible time and resource savings along with potential uses of VR for presurgical planning in orthopaedics.

- Background Over the next decade, the number of osteoarthritis consultations in health care is expected to increase. Physiotherapists may be considered equally qualified as primary assessors as physicians for patients with knee osteoarthritis. However, economic evaluations of this model of care have not yet been described. To determine whether physiotherapists as primary assessors for patients with suspected knee osteoarthritis in primary care are a cost-effective alternative compared with traditional physician-led care, we conducted a cost-effectiveness analysis alongside a randomized controlled pragmatic trial. Methods Patients were randomized to be assessed and treated by either a physiotherapist or physician first in primary care. A cost-effectiveness analysis compared costs and effects in quality adjusted life years (QALY) for the different care models. Analyses were applied with intention to treat, using complete case dataset, and missing data approaches included last observation carried forward and multiple imputation. Non-parametric bootstrapping was conducted to assess sampling uncertainty, presented with a cost-effectiveness plane and cost-effectiveness acceptability curve. Results 69 patients were randomized to a physiotherapist (n = 35) or physician first (n = 34). There were significantly higher costs for physician visits and radiography in the physician group (p < 0.001 and p = 0.01). Both groups improved their health-related quality of life 1 year after assessment compared with baseline. There were no statistically significant differences in QALYs or total costs between groups. The incremental cost-effectiveness ratio for physiotherapist versus physician was savings of 24,266 euro/lost QALY (societal perspective) and 15,533 euro/lost QALY (health care perspective). There is a 72-80% probability that physiotherapist first for patients with suspected knee osteoarthritis is less costly and differs less than +/- 0.1 in QALY compared to traditional physician-led care. Conclusion These findings suggest that physiotherapist-led care model might reduce health care costs and lead to marginally less QALYs, but confidence intervals were wide and overlapped no difference at all. Health consequences depending on the profession of the first assessor for knee osteoarthritis seem to be comparable for physiotherapists and physicians. Direct access to physiotherapist in primary care seems to lead to fewer physician consultations and radiography. However, larger clinical trials and qualitative studies to evaluate patients' perception of this model of care are needed.

- It is not known how physical exercise affects the risk of different types of fractures, especially in highly active individuals. To investigate this association, we studied a cohort of 118,204 men and 71,757 women who from 1991 to 2009 participated in Vasaloppet, a long-distance cross-country skiing race in Sweden, and 505,194 nonparticipants frequency-matched on sex, age, and county of residence from the Swedish population. Participants ranged from recreational exercisers to world-class skiers. Race participation, distance of race run, number of races participated in, and finishing time were used as proxies for physical exercise. Incident fractures from 1991 to 2010 were obtained from national Swedish registers. Over a median follow-up of 8.9 years, 53,175 fractures of any type, 2929 hip, 3107 proximal humerus, 11,875 lower leg, 11,733 forearm, and 2391 vertebral fractures occurred. In a Cox proportional hazard regression analysis using time-updated exposure and covariate information, participation in the race was associated with an increased risk of any type of fracture (hazard ratio [HR], 1.02; 95% CI, 1.00 to 1.05); forearm fractures had an HR, 1.11 with a 95% CI, 1.06 to 1.15. There was a lower risk of hip (HR, 0.75; 95% CI, 0.67 to 0.83), proximal humerus (HR, 0.90; 95% CI, 0.82 to 0.98), and lower leg fractures (HR, 0.93; 95% CI, 0.89 to 0.97), whereas the HR of vertebral fracture was 0.97 with a 95% CI, 0.88 to 1.07. Among participants, the risk of fracture was similar irrespective of race distance and number of races run. Participants close to the median finishing time had a lower risk of fracture compared with faster and slower participants. In summary, high levels of physical exercise were associated with a slightly higher risk of fractures of any type, including forearm fractures, but a lower risk of hip, proximal humerus, and lower leg fractures.

- Background: Studies have shown that specific characteristics of prevalent vertebral fractures are associated with a markedly low bone mineral density. This study evaluates if these characteristics also predict subsequent fractures. Methods: MrOS (Mister Osteoporosis) Sweden is a population-based, prospective observational study that includes 3014 community-living men who are sixty-nine to eighty-one years of age. At baseline, 1453 men underwent lateral thoracic and lumbar spine radiography; radiographs of 1427 men were readable. A radiologist identified and characterized prevalent vertebral fractures. Incident fractures during the next five and ten years were objectively registered with use of radiographs. The annual fracture incidence and relative risk of sustaining new fractures were assessed for men with and without baseline prevalent vertebral fracture. Data are presented as the mean and the 95% confidence interval. Results: There were 215 men (15.1%) with at least one prevalent vertebral fracture. During the five-year follow-up, these men had a relative risk of 3.3 (95% confidence interval, 2.6 to 4.3) of sustaining new fractures. The relative risk of sustaining any fracture was especially high in men with two or more prevalent vertebral fractures at 5.5 (95% confidence interval, 3.7 to 7.8), in men with different types of prevalent vertebral fractures at 5.7 (95% confidence interval, 3.6 to 8.5), in men with prevalent fractures in both the thoracic and lumbar regions at 6.4 (95% confidence interval, 4.5 to 8.8), and in men with prevalent fractures with a degree of vertebral body compression in the three worst quartiles, with the relative risk for the worst quartile at 4.0 (95% confidence interval, 2.6 to 5.9). Conclusions: Older men with a prevalent vertebral fracture have three times increased risk of sustaining new fractures compared with men without a vertebral fracture. Older men with two or more prevalent vertebral fractures, different types of fractures (wedge, biconcave, and/or crush), fractures in both the thoracic and lumbar regions, and a degree of vertebral body compression in the three worst quartiles are at an especially high risk of sustaining new fractures. Older men with prevalent vertebral fractures should be considered for fracture-prevention efforts.

- Introduction: The fixation of small intraarticular bone fragments is clinically challenging and an obvious first orthopaedic indication for an effective bone adhesive. In the present study the feasibility of bonding freshly harvested human trabecular bone with OsStic(R), a novel phosphoserine modified cement, was evaluated using a bone cylinder model pull-out test and compared with a commercial fibrin tissue adhesive. Methods: Femoral heads (n=13) were collected from hip fracture patients undergoing arthroplasty and stored refrigerated overnight in saline medium prior to testing. Cylindrical bone cores with a pre-inserted bone screw, were prepared using a coring tool. Each core was removed and glued back in place with either the bone adhesive (alpha-tricalcium phosphate, phosphoserine and 20% trisodium citrate solution) or the fibrin glue. All glued bones were stored in bone medium at 37 degrees C. Tensile loading, using a universal testing machine (5 kN load cell), was applied to each core/head. For the bone adhesive, bone cores were tested at 2 (n=13) and 24 (n=11) hours. For the fibrin tissue adhesive control group (n=9), bone cores were tested exclusively at 2 hours. The femoral bone quality was evaluated with micro-CT. Results: The ultimate pull-out load for the bone adhesive at 2 hours ranged from 36 to 171 N (mean 94 N, SD 42 N). At 24 hours the pull-out strength was similar, 47 to 198 N (mean 123 N, SD 43 N). The adhesive failure usually occurred through the adhesive layer, however in two samples, at 167 N and 198 N the screw pulled out of the bone core. The fibrin tissue adhesive group reached a peak force of 8 N maximally at 2 hours (range 2.8-8 N, mean 5.4 N, SD 1.6 N). The mean BV/TV for femoral heads was 0.15 and indicates poor bone quality. Conclusion: The bone adhesive successfully glued wet and fatty tissue of osteoporotic human bone cores. The mean ultimate pull-out force of 123 N at 24 hours corresponds to similar to 300 kPa shear stress acting on the bone core. These first ex-vivo results in human bone are a promising step toward potential clinical application in osteochondral fragment fixation. (C) 2022 The Authors. Published by Elsevier Ltd.
