- BackgroundThere are increasing demands on health care for both results and quality. Treatment outcome from the patient’s perspective is essential but not often demanded. The aim of the study was to assess Health Related Quality of Life (HRQoL) prior to and one year after an elective orthopedic intervention.MethodsHRQoL was evaluated by the 5-dimensional scale of the EuroQoL (EQ5D) with two additional scales, EQVAS and PainVAS in 676 consecutive patients undergoing 120 different elective orthopedic interventions. Descriptive statistics were used.ResultsResults showed patients treated for arthrosis with total hip and knee replacement had the greatest improvement in HRQoL. Patients that underwent spinal, upper arm and arthroscopic knee surgery showed considerable improvement. All patients experienced pain relief one year after surgery. Changes in the three effect variables EQ5D, EQVAS and PainVAS correlated significantly with each other.ConclusionsThe study provides an overview of patient assessment of HRQoL before and after some of the most common elective orthopedic interventions. Knowledge obtained from patient groups should help improve and individualize care both from a nursing and surgical perspective.

- Objectives: To investigate health-related factors associated with self-rated race performance outcomes among recreational long-distance runners. Design: Panel study. Methods: Data were collected from runners one month before and after a community-level race event including distances from 8 to 42.2 km. The primary outcome measure was self-rated race performance outcome. The explanatory variables represented health complaints suffered during the build-up year, the pre-race month, and the race and among full marathon runners predicted objective performance outcome (mean pace equal to training pace or faster). Multiple logistic regression was used to determine factors associated with the self-rated performance outcome. Results: Two-hundred forty-five runners (29%) provided complete data sets. Seventy-four percent of the runners reached their desired race performance outcome. Achievement of the performance outcome was more likely when having avoided illness during the build-up and pre-race periods (OR = 3.8; 95% CI:1.8-8.0, p amp;lt; 0.001), having avoided per-race injury (OR=3.0; 95% CI:1.2-7.4, p = 0.02) and avoided perrace illness (OR= 4.1; 95% CI:1.3-15, p = 0.020). Having obtained the self-rated performance outcome was also associated with running a shorter distance (OR=3.6; 95% CI: 1.7-8.0,p = 0.001) and being younger than 50 years of age (OR= 2.4; 95% CI:1.1-5.3-8.3, p = 0.03). Having met the predicted objective performance outcome predisposed marathon runners to also obtain the self-rated performance outcome (OR= 4.7, 95% CI: 1.5-16, p amp;lt; 0.01). Conclusions: Having avoided illness during build-up and pre-race was positively associated with self-rated race performance outcome among recreational runners. Adjusting the desired performance outcomes with regard to recent illness and age may help recreational runners to more often achieve their goals and thereby prevent them from leaving the sport.

- Background: During 1978 and 1979, we initiated a prospective multicenter study to evaluate the results of nonoperative treatment of primary anterior shoulder dislocation. In the current report, we present the outcome after twenty-five years.Methods: Two hundred and fifty-five patients (257 shoulders) with an age of twelve to forty years who had a primary anterior shoulder dislocation were managed with immobilization (achieved by tying the arm to the torso with use of a bandage) or without immobilization. All 227 living patients (229 shoulders) completed the follow-up questionnaire, and 214 patients completed the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire.Results: Ninety-nine (43%) of 229 shoulders had not redislocated, and seventeen (7%) redislocated once. Thirty-three recurrent dislocations had become stable over time (14.4%), and eighteen were considered to be still recurrent (7.9%). Sixty-two shoulders (27%) had undergone surgery for the treatment of recurrent instability. Immobilization after the primary dislocation did not change the prognosis. Only two of twenty-four shoulders with a fracture of the greater tuberosity at the time of the primary dislocation redislocated (p < 0.001). When shoulders with a fracture of the greater tuberosity were excluded, forty-four (38%) of 115 shoulders in patients who had been twelve to twenty-five years of age at the time of the original dislocation and sixteen (18%) of ninety shoulders in patients who had been twenty-six to forty years of age had undergone surgical stabilization. At twenty-five years, fourteen (23%) of sixty-two shoulders that had undergone surgical stabilization were in patients who subsequently had a contralateral dislocation, compared with seven (7%) of ninety-nine shoulders in patients in whom the index dislocation had been classified as solitary (p = 0.01). Gender and athletic activity did not appear to affect the redislocation rate; however, women had worse DASH scores than men did (p = 0.006).Conclusions: After twenty-five years, half of the primary anterior shoulder dislocations that had been treated nonoperatively in patients with an age of twelve to twenty-five years had not recurred or had become stable over time.Level of Evidence: Prognostic Level I. See Instructions to Authors for a complete description of levels of evidence.

- The interest for surgery simulator systems with anatomical models generated from authentic patient data is growing as these systems evolve.With access to volumetric patient data, e.g., from a computer tomography scan, haptic and visual feedback can be created directly from this dataset. This opens the door for patient specific simulations. Hip fracture surgery is one area where simulator systems is useful to train new surgeons and plan operations. To simulate the drilling procedure in this type of surgery, a repositioning of the fractured bone into correct position is first needed. This requires a segmentation process in which the bone segments are identified and the position of the dislocated part is determined. The segmentation must be automatic to cope with the large amount of data from the computer tomography scan. This work presents the first steps in the development of a hip fracture surgery simulation with patient specific models. Visual and haptic feedback is generated from the computer tomography data by simulating fluoroscopic images and the drilling process. We also present an automatic segmentation method to identify the fractured bone and determine the dislocation. This segmentation method is based on nonrigid registration with the Morphon method.

- BACKGROUND: International middle- and long-distance running competitions attract millions of spectators in association with city races, world championships, and Olympic Games. It is therefore a major concern that ill health and pain, as a result of sports overuse, lead to numerous hours of lost training and decreased performance in competitive runners. Despite its potential for sustenance of performance, approval of mHealth self-report monitoring (mHSM) in this group of athletes has not been investigated.OBJECTIVE: The objective of our study was to explore individual and situational factors associated with the acceptance of long-term mHSM in competitive runners.METHODS: The study used qualitative research methods with the Technology Acceptance Model as the theoretical foundation. The study population included 20 middle- and long-distance runners competing at national and international levels. Two mHSM apps asking for health and training data from track and marathon runners were created on a platform for web survey development (Briteback AB). Data collection for the technology acceptance analysis was performed via personal interviews before and after a 6-week monitoring period. Preuse interviews investigated experience and knowledge of mHealth monitoring and thoughts on benefits and possible side effects. The postuse interviews addressed usability and usefulness, attitudes toward nonfunctional issues, and intentions to adhere to long-term monitoring. In addition, the runners' trustworthiness when providing mHSM data was discussed. The interview data were investigated using a deductive thematic analysis.RESULTS: The mHSM apps were considered technically easy to use. Although the runners read the instructions and entered data effortlessly, some still perceived mHSM as problematic. Concerns were raised about the selection of items for monitoring (eg, recording training load as running distance or time) and about interpretation of concepts (eg, whether subjective well-being should encompass only the running context or daily living on the whole). Usefulness of specific mHSM apps was consequently not appraised on the same bases in different subcategories of runners. Regarding nonfunctional issues, the runners competing at the international level requested detailed control over who in their sports club and national federation should be allowed access to their data; the less competitive runners had no such issues. Notwithstanding, the runners were willing to adhere to long-term mHSM, provided the technology was adjusted to their personal routines and the output was perceived as contributing to running performance.CONCLUSIONS: Adoption of mHSM by competitive runners requires clear definitions of monitoring purpose and populations, repeated in practice tests of monitoring items and terminology, and meticulousness regarding data-sharing routines. Further naturalistic studies of mHSM use in routine sports practice settings are needed with nonfunctional ethical and legal issues included in the evaluation designs.

- The authors have evaluated a trauma simulator based on virtual reality techniques. Ten surgeons and 15 medical students performed distal locking of a femoral nail (A). Furthermore, 10 medical students performed simulated osteosynthesis of a femoral neck fracture (B). Total surgery time (A) (mean value) was shorter for surgeons (108 s) compared with students (157 s) at the first (p = 0.033), second (102 respectively 138 s, p = 0.13) and third (96 respectively 160 s, p = 0.15) operation. Total fluoroscopy time (A) (mean value) was shorter for surgeons compared with students at the first (45 respectively 89s p = 0.001), second (48 respectively 83 s, p = 0.02) and third (50 respectively 107 s, p = 0.10) operation. The positioning of the hip nails (B) improved between the first and last trial. Total surgery and fluoroscopy time were reduced. All participants thought that this and similar simulators should be part of the programme and that this simulator would be helpful if they were about to learn the procedures).

Associations between recreational runners anti-inflammatory drug use, coping strategies, and time loss due to injury and illness during preparations for a marathon event
- 2018
-
Ingår i: Journal of Sports Medicine and Physical Fitness. - : EDIZIONI MINERVA MEDICA. - 0022-4707 .- 1827-1928. ; 58:12, s. 1839-1843

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Due to the dominance of overuse injuries among runners, knowledge of how use of non-steroidal anti-inflammatory drugs (NSAIDs) and behavioral factors contribute to injury events is important. The aim of this study was to explore recreational marathon runners strategies for coping with injury and illness, including use of drugs for control of pain and inflammation, and to investigate whether these strategies were associated with the 1-year prevalence of time-loss injury and illness. METHODS: An online questionnaire was used for data collection in this cross-sectional study. The population consisted of runners who had registered for a marathon (N.=341). Strategies used to understand and manage perceptions of injury and illness were measured with the Brief COPE instrument and the use of NSAIDs was investigated. RESULTS: Complete survey data were provided by 161 runners (47%). 42% reported NSAID use. A notable injury in the past year was reported by 43%, and 19% reported having had a time-loss illness episode. Runners who reported NSAID use in the past year reported significantly fewer time-loss injuries (P=0.003). Time loss due to illness only showed a negative correlation with using emotional support for coping (P=0.010) and a positive correlation with self-blame (P=0.039). CONCLUSIONS: Runners stating NSAID use reported fewer time-loss running injuries than non-NSAID users. Time loss due to illness showed different correlates with NSAID use and coping strategies than time loss due to injury, i.e. no association with drug use, less use of emotional support for coping and more use of self-blame.

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.

Effect of steroid injections on the rotator cuff : An experimental study in rats
- 1999

Tidskriftsartikel (refereegranskat)abstract
- 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.
