BackgroundThe growing enthusiasm for the use of reverse shoulder arthroplasty (RSA) in the treatment of primary glenohumeral osteoarthritis (GHOA) with an intact rotator cuff is based on data derived from single-center studies with limited generalizability and follow-up. This study compared patient-reported outcomes (PROs) between RSA and total shoulder arthroplasty (TSA) for the treatment of primary GHOA with up to 5-year follow-up and examined temporal trends in the treatment of GHOA between 2012 and 2021.MethodsA retrospective review was performed on patients with primary GHOA undergoing primary arthroplasty surgery from the Surgical Outcomes System global registry between 2012 and 2021. PROs including the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, and visual analog scale (VAS) for pain were compared between RSA and TSA at 1, 2, and 5 years postoperatively.ResultsA total of 4451 patients were included, with 2693 (60.5%) undergoing TSA and 1758 (39.5%) undergoing RSA. Both RSA and TSA provided clinically excellent outcomes at 1 year postoperatively (ASES: 80.8 ± 17.9 vs. 85.9 ± 15.2, respectively; SANE: 74.8 ± 24.7 vs. 79.5 ± 22.9; VAS pain: 1.3 ± 2.0 vs. 1.1 ± 1.7; all P < .05) that were maintained at 2 years (ASES: 81.3 ± 19.3 vs. 87.3 ± 14.9; SANE: 74.8 ± 26.2 vs. 79.7 ± 24.7; VAS pain: 1.3 ± 2.1 vs. 1.0 ± 1.6; all P < .05) and 5 years (ASES: 81.7 ± 16.5 vs. 86.9 ± 15.3; SANE: 71.6 ± 28.5 vs. 78.2 ± 25.9; VAS pain: 1.0 ± 1.7 vs. 1.0 ± 1.7; all P < .05), with statistical significance favoring TSA. After controlling for age and sex, there was an adjusted difference of 4.5 units in the ASES score favoring TSA (P = .005) at 5 years postoperatively but no differences in adjusted SANE (P = .745) and VAS pain (P = .332) scores. The use of RSA for GHOA grew considerably over time, from representing only 17% of all replacements performed for GHOA in 2012 to nearly half (47%) in 2021 (P < .001).ConclusionRSA as a treatment for GHOA with an intact rotator cuff seems to yield PROs that are largely clinically equivalent to TSA extending to 5 years postoperatively. The observed statistical significance favoring TSA appears to be of marginal clinical benefit based on established minimal clinically important differences and may be a result of the large sample size. Further research using more granular clinical data and examining differences in range of motion and complications is warranted as it may change the value analysis. 相似文献

IntroductionThere is an increased demand of telemedicine in the recent century, especially with the outbreak of Covid-19. The aim of this study was to investigate patients' reliability in self-assessing own elbow range of motion following surgery for trauma.MethodsAll patients of age ≥16 years who underwent surgery for elbow trauma at the local trauma unit between March 2015 to Aug 2018 were reviewed retrospectively. Identified cohort was invited to self-assess their elbow range of motion (ROM) using questionnaire with image instruction. They were then followed up with a clinical review for objective measurements by the lead clinician. Independent T-test was used to compare the measurements between patients and clinician. The power of the study was calculated using G1Power software.ResultsThirty-five patients were enrolled in the study with mean age of 41 years. 11 of 35 patients had an associated elbow fracture dislocation associated. Mean patient reported total ROM was 105.7° ± 32.8°, with mean extension of 24.6° ± 18.9° to mean flexion of 130.3° ± 18.2°. Mean objective ROM measured by lead clinician was 112.6° ± 18.3°, with mean extension 22.4° ± 10.9° to mean flexion 135.0° ± 10.8°. No statistical significance was found between self-reported and clinician-based extension (p = 0.36), flexion (p = 0.076), and overall range of motion (p = 0.12).ConclusionPatients can self-assess their elbow range of motion following surgery for trauma accurately. In the midst of increasing demands for telemedicine, we suggest the application of patients' self-reporting outcome in clinical settings. 相似文献

Elbow injuries are common in children and while majority heal very well, some result in deformities of the elbow. Although deformities such as cubitus varus and non-progressive cubitus valgus are considered cosmetic by the paediatric orthopaedic surgeons and intentionally ignored, they are not always benign and can result in functional deficit due to instability, pain, tardy nerve palsies and osteoarthritis later in life. Similarly congenital and developmental conditions that do not cause major functional loss in childhood, become very disabling in adults due to increasing functional demands. Congenital radial head dislocation and radioulnar synostosis fall into this category. In this paper we discuss clinical presentation, treatment options and outcomes of common elbow conditions presenting later in the life. 相似文献

Tendinopathies are common causes of pain around the elbow resulting in significant functional impairment in athletes or the working-age population. Patients complain of a gradual onset pain with or without any specific trauma. Tissue histology shows chronic fibroblast and vascular proliferation, with a disorganized collagen pattern and absence of inflammatory mediators. Currently, numerous treatment options are described, but many of these are only supported by a heterogenous evidence base. Thus, management guidelines are difficult to define. Surgery is mostly indicated in selected cases that have failed non-operative management. This article reviews the pathophysiology and natural history of lateral and medial elbow tendinopathies, as well as distal biceps and triceps tendinopathies, and their current treatment options. 相似文献
