BACKGROUND: To evaluate the clinical outcome of revision of primary shoulder replacement by using reverse total shoulder arthroplasty (RTSA). METHODS: Seven patients underwent revision RTSA with a mean follow-up of 22.1 months (range, 12 to 54 months). Their mean age at the time of operation was 75.5 years (range, 70 to 80 years). Assessments were performed on the preoperative and postoperative visual analogue scale (VAS) score, muscle strength, range of motion, University of California at Los Angeles (UCLA) score, Constant score, subjective satisfaction and the anteroposterior and axillary views of the glenohumeral joint...

BACKGROUND: Complex proximal humeral fractures may require prosthetic replacement of the humeral head. Surgical options include reverse shoulder arthroplasty (RSA) and shoulder hemiarthroplasty; however, the optimal technique remains controversial. The goal of this study was to compare functional outcomes and revision rates of RSA with hemiarthroplasty in patients with acute proximal humeral fractures. MATERIALS AND METHODS: Between January 1, 1999, and December 31, 2014, there were 218 patients who underwent RSA and 427 who underwent hemiarthroplasty for acute proximal humeral fractures identified through New Zealand Joint Registry records...

Background and purpose - For more than half a century, stemmed hemiarthroplasty (SHA) has been used in the treatment of comminuted and displaced fractures of the proximal humerus. Reverse shoulder arthroplasty (RSA) has been increasingly popular in cases where it is difficult to obtain satisfactory fixation of the tuberosities. We report revision rates and reasons for revision after shoulder arthroplasty for acute fractures of the proximal humerus. Patients and methods - This study was based on a common dataset from the Nordic Arthroplasty Register Association (NARA), which includes data reported to the national shoulder arthroplasty registries in Denmark, Sweden, and Norway...

BACKGROUND: Proximal humeral fractures are common in older patients. The majority are minimally displaced and are associated with good outcomes after nonoperative treatment. Poorer outcomes are associated with displaced, multipart fractures. There is no clear benefit from surgical fracture fixation compared to nonoperative treatment. Replacement of the fractured humeral head with a hemiarthroplasty is another treatment option, but has not been shown to be clearly superior to nonoperative treatment or internal fixation...

PURPOSE: the past decade has seen a considerable increase in the use of research models to study reverse total shoulder arthroplasty (RTSA). Nevertheless, none of these models has been shown to completely reflect real in vivo conditions. METHODS: we performed a systematic review of the literature matching the following key words: "reverse total shoulder arthroplasty" or "reverse total shoulder replacement" or "reverse total shoulder prosthesis" and "research models" or "biomechanical models" or "physical simulators" or "virtual simulators"...

BACKGROUND: Shoulder arthroplasty is an effective procedure for managing patients with shoulder pain secondary to end-stage arthritis. Insurance status has been shown to be a predictor of patient morbidity and mortality. The current study evaluated the effect of patient insurance status on perioperative outcomes after shoulder replacement surgery. METHODS: Data between 2004 and 2011 were obtained from the Nationwide Inpatient Sample. Analysis included patients undergoing shoulder arthroplasty (partial, total, and reverse) procedures determined by International Classification of Disease, 9th Revision procedure codes...

BACKGROUND: Cellular remodeling in rotator cuff muscles following a massive rotator cuff tear is poorly understood. The aim of the current study was to provide histological evidence to elucidate the mode of muscle loss in advanced human rotator cuff disease and to assess tissue-level changes in relation to findings on noninvasive imaging. METHODS: Rotator cuff muscle biopsy samples were taken from the scapular fossae from 23 consecutive patients undergoing reverse total shoulder arthroplasty in order to evaluate muscle composition in severe rotator cuff disease...

Thumb carpometacarpal joint replacement is associated with high rates of loosening and failure. We present our results for an uncemented ceramic-ceramic total joint prosthesis with a reverse ball-and-socket design and bioactive coating. Between 2008 and 2012, 29 prostheses were inserted into 28 patients (mean age 63 years) with advanced osteoarthritis. After a mean period of 33 months (range 9-62), 26 patients (27 implants) were available for follow-up. Six months postoperatively, 50% of the patients had radiological evidence of early loosening...

BACKGROUND: Geriatric traumatology is increasing in importance due to the demographic transition. In cases of fractures close to large joints it is questionable whether primary joint replacement is advantageous compared to joint-preserving internal fixation. OBJECTIVE: The aim of this study was to describe the importance of prosthetic joint replacement in the treatment of geriatric patients suffering from frequent periarticular fractures in comparison to osteosynthetic joint reconstruction and conservative methods...

BACKGROUND: Shoulder pain and loss of function are directly associated with obesity. QUESTIONS/PURPOSES: We hypothesized that significant interactions would exist between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RSA) and obesity status on functional and quality of life (QOL) outcomes over the long term. Clinical and QOL outcomes (American Shoulder and Elbow Surgeons Evaluation form, Shoulder Pain and Disability Index, University of California at Los Angeles Shoulder Rating scale, Medical Outcomes Short Form 12 (SF-12), range of motion (ROM), and strength) were longitudinally compared in patients with low and high body mass index (BMI) after a TSA or a RSA...

INTRODUCTION: The most frequent indications for anatomic shoulder replacement are glenohumeral osteoarthritis and fractures of the humeral head. If anatomic shoulder prostheses fail, reverse total shoulder arthroplasty is often the only remaining treatment option. This study evaluates the influence of indications for primary shoulder arthroplasty on the clinical outcome after conversion to reverse total shoulder arthroplasty. MATERIALS AND METHODS: From 2010 to 2012, 44 failed shoulder arthroplasties were converted to reverse total shoulder arthroplasty...

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...

Carl Chisholm, Peter C Poon
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...
