RESUMO
INTRODUCTION: As a consequence of the Swedish model, endoprosthesis registers have become increasingly important worldwide. Due to the increasing number of joint replacements at the shoulder, these are being increasingly included in the register databases - in addition to interventions at the hip and knee joint. In this study, the value of endoprosthesis registers is investigated, using the example of shoulder endoprosthetics and including a comparison with clinical studies. MATERIAL AND METHODS: The annual reports of 32 different endoprosthesis registers with data on hip, knee and/or shoulder arthroplasty were analysed. The number of operations and demographic patient data for all areas of endoprosthetics were examined. In addition, a more detailed consideration of variables such as the primary diagnosis, the cause of the revision, the revision rate depending on risk factors and patient-reported outcome measures (PROM scores) was carried out exclusively for the shoulder joint endoprostheses. Using the example of the inverse shoulder prosthesis, clinical studies were compared to registry data with special regard to the revision rate. RESULTS: A total of 20 endoprosthesis registers could be included, 9 of these collected data on shoulder arthroplasty. The main primary diagnoses were osteoarthritis (40.6%), rotator cuff defect arthropathy (30.2%) and fractures (17.6%). The most commonly used shoulder joint endoprosthesis was the inverse prosthesis (47.3%). The proportion of revision surgeries in total shoulder arthroplasty operations was less than 10% in all registers. In addition to the revision rate, the PROM scores were sometimes used in the registers to evaluate the success of the prosthesis. Compared to registry data, clinical studies showed more heterogeneous data with a significantly higher revision rate of over 10% in long-term follow-up - using the example of the inverse shoulder prosthesis. CONCLUSION: Register data are a valuable source of information in shoulder arthroplasty and can make a significant contribution to the quality assurance of endoprosthetic treatments. Compared to clinical studies, they primarily provide data on durability of different endoprosthesis and give lower revision rates. Clinical studies use PROM scores and clinical and radiological examinations to focus only on individual implants and surgical centres on the one hand and much more on the functional results on the other.

OBJECTIVE: To identify, summarise and critically assess economic evaluation studies on sports injury prevention strategies. DESIGN: Systematic review. DATA SOURCES: PubMed, SportDiscuss. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: The current literature was searched following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Economic analyses published since 2010 were checked for inclusion. The methodological quality of the studies was assessed using the Oxford Level of Evidence for economic and decision analysis; underlying randomised controlled trials (RCTs) were rated according to the Physiotherapy Evidence Database (PEDro) Scale, and risk of bias was assessed using the Revised Cochrane risk-of-bias tool. RESULTS: Ten studies fulfilled the inclusion criteria. The quality assessment revealed limited data quality. For trial-based analysis, underlying RCTs were of good quality and had a low risk of bias. Prevention concepts for general injury reduction showed effectiveness and cost savings. Regarding specific injury types, the analysis of the studies showed that the best data are available for ankle, hamstring and anterior cruciate ligament injuries. Measures using specific training interventions were the predominant form of prevention concepts; studies investigating these concepts showed cost-effectiveness with total cost savings between 24.82 and 462 per athlete. CONCLUSION: Injury prevention strategies that were studied are cost-effective. However, estimates and outcomes vary throughout the included studies, and precluded pooling of existing data. Knowledge about the cost-effectiveness of evaluated prevention measures will help improve the acceptance and application of prevention initiatives.

The aim of this randomized controlled laboratory study was to evaluate the role of standardized protection, rest, ice (cryotherapy), compression and elevation (PRICE) therapy on microvascular blood flow in human skeletal muscle. Quantifiable contrast-enhanced ultrasound was used to analyze intramuscular tissue perfusion (ITP) of the rectus femoris (RF) and vastus intermedius (VI) muscles in 20 healthy athletes who were randomly assigned to PRICE or control groups. Baseline perfusion measurements (resting conditions, T0) were compared with cycling exercise (T1), intervention (PRICE or control, T2) and follow-up at 60 min post-intervention (T3). The 20 min PRICE intervention included rest, cryotherapy (3°C), compression (35 mm Hg) and elevation. After intervention, PRICE demonstrated a decrease of ITP in VI (-47%, pâ¯=â¯0.01) and RF (-50%, pâ¯=â¯0.037) muscles. At T3, an ongoing decreased ITP for the RF (pâ¯=â¯0.003) and no significant changes for the VI were observed. In contrast, the control group showed an increased ITP at T2 and no significant differences at T3. PRICE applied after exercise led to a down-regulation of ITP, and the termination of PRICE does not appear to be associated with a reactive hyperemia for at least 60 min after treatment.

BACKGROUND: Cost analysis studies in medicine were uncommon in the past, but with the rising importance of financial considerations, it has become increasingly important to use available resources most efficiently. PURPOSE: To analyze the current state of cost-effectiveness analyses in shoulder surgery. STUDY DESIGN: Systematic review; Level of evidence, 4. METHODS: A systematic review of the current literature was performed following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. All full economic analyses published since January 1, 2010 and including the terms "cost analysis" and "shoulder" were checked for usability. The methodological quality of the studies was assessed using the Oxford Centre for Evidence-Based Medicine levels of evidence and established health economic criteria (Quality of Health Economic Studies [QHES] instrument). RESULTS: A total of 34 studies fulfilled the inclusion criteria. Compared with older studies, recent studies were of better quality: one level 1 study and eight level 2 studies were included. The mean QHES score was 87 of 100. The thematic focus of most studies (n = 13) was rotator cuff tears, with the main findings as follows: (1) magnetic resonance imaging is a cost-effective imaging strategy, (2) primary (arthroscopic) rotator cuff repair (RCR) with conversion to reverse total shoulder arthroplasty in case of failure is the most cost-effective strategy, (3) the platelet-rich plasma augmentation of RCR seems not to be cost-effective, and (4) the cost-effectiveness of double-row RCR remains unclear. Other studies included shoulder instability (n = 3), glenohumeral osteoarthritis (n = 3), proximal humeral fractures (n = 4), subacromial impingement (n = 4), and other shoulder conditions (n = 7). CONCLUSION: Compared with prior studies, the quality of recently available studies has improved significantly. Current studies could help decision makers to appropriately and adequately allocate resources. The optimal use of financial resources will be of increasing importance to improve medical care for patients. However, further studies are still necessary.
