Many patients prioritize the ability to return to sports following shoulder replacement surgeries, including total shoulder arthroplasty (TSA), reverse total shoulder arthroplasty (RTSA), and hemiarthroplasty (HA). While activity levels after hip and knee replacements have been well-established in the literature, studies on this topic in the field of shoulder arthroplasty are relatively limited. A review of the literature regarding athletic activity after shoulder arthroplasty was performed using the PubMed database...

INTRODUCTION: The aim of this study was to investigate the stabilizing influence of the rotator cuff as well as the importance of glenosphere and onlay configuration on the anterior stability of the reverse total shoulder replacement (RTSR). MATERIALS AND METHODS: A reverse total shoulder replacement was implanted into eight human cadaveric shoulders, and biomechanical testing was performed under three conditions: after implantation of the RTSR, after additional dissection of the subscapularis tendon, and after additional dissection of the infraspinatus and teres minor tendon...

As of now few studies have investigated the kinematics of the reverse shoulder arthroplasty (RSA) in patients and none on how this may be affected by glenosphere shape or size. There have been a few biomechanical studies evaluating the RSA. These studies have modelled and estimated that a large amount of movement is available at the glenohumeral articulation, when using a standard glenosphere, with even more movement using an eccentric or large glenosphere. However, the in vivo kinematics of the RSA has not been determined...

BACKGROUND: Total shoulder arthroplasty for end-stage glenohumeral arthritis with severe glenoid bone loss poses a unique challenge for shoulder surgeons. Current surgical solutions are limited and associated with high complication rates. We hypothesized that a custom-made computer-aided design-computer-aided manufacturing (CAD-CAM) total shoulder replacement (TSR; Stanmore Implants Worldwide, Elstree, UK) resembling a total hip prosthesis could offer a reliable alternative for this challenging subset of patients...

Arytenoid cartilage dislocation is not a common complication, but its delayed diagnosis reduces the therapeutic effect of treatment. A male patient underwent reversed total shoulder replacement surgery in the beach chair position under general anesthesia. The patient experienced postoperative hoarseness, and it was revealed that he had right arytenoid dislocation. Voice restoration was accomplished with closed reduction. We discussed changes in patient position during the operation and how they may contribute to the arytenoid dislocation...

BACKGROUND: Associations between socioeconomic position (SEP) and the uptake of primary total shoulder arthroplasty (TSA) is not well understood in the Australian population, thus potentially limiting equitable allocation of healthcare resources. We used the Australian Orthopaedic Association National Joint Replacement Registry (AOA NJRR) to examine whether geographic or socioeconomic variations exist in TSA performed for a diagnosis of osteoarthritis 2007-11 for all Australians aged ≥40 years...

The number of cases with rheumatoid arthritis who requires arthroscopic synovectomy is declining, but it is still a useful procedure in combination with effective pharmacologic disease control. For the destruction of glenohumeral joint, total shoulder arthroplasty is effective for pain relief and functional outcome for patients without rotator cuff impairment. The reverse shoulder arthroplasty has been shown favorable short-term results, but need a careful indication for rheumatoid shoulder with poor bone stock and bone quality...

OBJECTIVES: To evaluate the trajectory of the change in range of motion after reverse shoulder joint replacement during 3-year follow-up among patients with rheumatoid arthritis. METHODS: Retrospective cohort longitudinal study of 76 shoulder replacements performed in a university clinic. The range of shoulder motion was assessed by a physiotherapist using a manual goniometer with 5-degree precision before the surgery and 1, 3, 6, 12, and 36 months postoperatively...

PURPOSE: Glenoid component malposition is associated with poor function and early failure of both anatomic and reverse total shoulder arthroplasty. Glenoid positioning is challenging particularly in the setting of bone loss or deformity. Recently, the use of computer assistance has been shown to reduce implantation error. The aim of this study is to evaluate the accuracy of patient-specific instrumentation in cases of anatomic and reverse shoulder replacement in vivo. METHODS: Twenty patients underwent total shoulder arthroplasty using a computed tomography (CT)-based patient-specific instrumentation (PSI) system, ten anatomic and ten reverse...

BACKGROUND: Humeral head osteonecrosis treatment varies depending on the stage and symptoms. Successful outcomes for humeral head core decompression for stage I/II disease in chronic steroid-induced (CSI) osteonecrosis have been reported, but fewer data exist for sickle cell disease (SCD) etiology. Resurfacing and hemiarthroplasty or total shoulder arthroplasty (TSA) are common for advanced collapse, with mixed results. METHODS: We evaluate radiographic and functional outcomes after procedures for humeral head atraumatic avascular necrosis (HAAVN), decompression efficacy in CSI and SCD populations, and report outcomes of advanced disease requiring arthroplasty...

Reverse shoulder arthroplasty has become increasingly popular for the treatment of complex shoulder injuries, including proximal humerus fractures and fixed glenohumeral dislocation, in the elderly population. The early to midterm results of reverse shoulder arthroplasty for the treatment of proximal humerus fractures are promising compared with the results of unconstrained humeral head replacement, and patients may have more predictable improvement with less dependence on bone healing and rehabilitation. However, long-term follow-up is needed, and surgeons must be familiar with various complications that are specific to reverse shoulder arthroplasty...

The evolution of reverse shoulder arthroplasty has provided surgeons with new solutions for many complex shoulder problems. A primary goal of orthopaedics is the restoration or re-creation of functional anatomy to reduce pain and improve function, which can be accomplished by either repairing injured structures or replacing them as anatomically as possible. If reconstructible tissue is lacking or not available, which is seen in patients who have complex shoulder conditions such as an irreparable rotator cuff-deficient shoulder, cuff tear arthropathy, or severe glenoid bone loss, substantial problems may arise...

Advances in shoulder replacement surgery have allowed for the successful treatment of various shoulder conditions. As the elderly population increases and the surgical indications for shoulder replacement surgery continue to expand, the number of shoulder replacements performed annually will continue to increase. Accordingly, the number of complications also will be expected to increase. Successful shoulder replacement outcomes require surgeons to have a thorough understanding of the surgical indications, surgical technique, and potential complications of the procedure...

OBJECTIVE: To describe the demographics in a series of shoulder arthroplasty cases operated in a single hospital and by the same surgical team. MATERIAL AND METHODS: 120 shoulder arthroplasties performed between January 2006 and November 2014 were included. The following variables were analyzed: age, gender, baseline diagnosis, type of prosthesis used, comorbid conditions, involved side, occupation, follow-up time, and surgical history. RESULTS: Females accounted for 66% and males 34%; mean age was 66 years and the most frequent diagnosis was arthropathy resulting from rotator cuff tear (30%)...

Shoulder pain is a common problem for general practitioners. The objectives of a shoulder arthroplasty are to improve the articular function and to provide pain relief. Anatomic shoulder arthroplasty is not the treatment of choice if a rotator cuff deficiency is associated with arthritis. In some circumstances (muscle or tendon deficiency) rotator cuff repair is technically impossible. Reverse shoulder arthroplasty (RSA) has opened new opportunities for patients suffering with shoulder conditions such as shoulder pseudoparalysis and revision surgery...

BACKGROUND: Reverse shoulder prostheses are increasingly used in recent years for treatment of glenohumeral arthropathy with deficient rotator cuff. Bone preservation is becoming a major goal in shoulder replacement surgery. Metaphyseal humeral components without a stem were developed to minimize bone resection and preserve bone. This study evaluated the clinical and radiologic outcomes at 2 to 7 years using a novel short metaphyseal reverse total shoulder arthroplasty (rTSA) prosthesis without a diaphyseal stem...

The most common causes of revision surgery after reverse total shoulder arthroplasty (RTSA) are, in decreasing order: prosthetic instability (38%), infection (22%), humeral problems (21%) including loosening, unscrewing and fracture, and, lastly, problems of glenoid loosening (13%). Complications leading to reoperation are often multiple and their association is underestimated. It is not uncommon for patients to be reoperated several times due to the persistence of the same complication, failure to diagnose associated complications, or onset of an additional complication...

BACKGROUND: Traditionally, fewer postoperative sport restrictions are imposed on hemiarthroplasty (HHA) patients on than reverse total shoulder arthroplasty (RTSA) patients. However, functional outcomes have been shown to be superior in RTSA. No direct comparison of RTSA vs HHA has been done on rates of return to sports in patients with glenohumeral arthritis and rotator cuff dysfunction, proximal humeral fractures, or rheumatoid arthritis. METHODS: This is a retrospective review of consecutive RTSA and HHA patients collected from our institution's shoulder arthroplasty registry...
