The risks and complication profile of reverse total shoulder arthroplasty (RSA) in rheumatoid arthritis (RA) patients has yet to be clearly defined as most studies have small cohorts. Using a large inpatient database, the purpose on our study was to determine the overall demographics, hospitalization characteristics, and early complication rates in rheumatoid patients and compared these to rotator-cuff arthropathy patients without RA undergoing RSA. Utilizing United States Nationwide Inpatient Sample from 2010 to 2013, we evaluated a total of 919 RA RSA and compared them to 8097 patients without RA undergoing RSA...

BACKGROUND: Recent developments in reverse shoulder arthroplasty (RSA) have focused on changes in several design-related parameters, including humeral component design, to allow for easier convertibility. Alterations in humeral inclination and offset on shoulder kinematics may have a relevant influence on postoperative outcome. This study used a virtual computer simulation to evaluate the influence of humeral neck shaft angle and glenoid lateralization on range of motion in onlay design RSA...

BACKGROUND: Pseudoparalysis remains one of the most challenging conditions in shoulder surgery. Long thought of as an unsolvable problem, recent advances in surgical techniques offer potential return of overhead motion in the setting of massive irreparable rotator cuff tears. This article summarizes the available literature including existing definitions and the results of different treatment approaches regarding range of motion, outcome scores, and reversal. METHODS: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of the MEDLINE database, Cochrane database, Physiotherapy Evidence Database, and Google Scholar database was performed for studies that defined a preoperative shoulder group as having pseudoparalysis...

Parkinson's disease (PD) is a progressive neurologic disorder that affects the musculoskeletal system. Currently, the use of reverse shoulder arthroplasty (RSA) for patients with PD has not been adequately studied. The authors sought to determine if RSA provided similar functional outcomes for patients with PD compared with a matched cohort of patients without PD. Between 2004 and 2011, 10 patients with PD (4 men, 6 women) underwent RSA. Patients with PD were matched to patients without PD at a 1:4 ratio based on age (average, 76 years; range, 63-85 years), sex (16 men, 24 women), preoperative diagnosis, and length of follow-up (average, 43 months; range, 24-128 months)...

Synovial chondromatosis affecting the glenohumeral joint is rare. Treatment primarily consists of arthroscopic loose body removal and synovectomy. Shoulder arthroplasty has been mentioned in the literature as a treatment option for patients with coexisting arthritis, although the results have been underreported. The case of an 84-year-old man with long standing synovial chondromatosis of the shoulder resulting in severe degenerative disease is presented. The patient was treated with a reverse total shoulder arthroplasty, loose body removal, and a complete synovectomy...

BACKGROUND: Os acromiale has been reported in up to 15% of the general population. Reverse total shoulder arthroplasty (RTSA) increases deltoid tension, which could potentially lead to excessive stress on a pre-existent os acromiale. The purpose of this study was to determine the outcome and complications of primary RTSA in patients with radiographic evidence of an os acromiale. METHODS: Between 2005 and 2013, 25 shoulders underwent primary RTSA with an associated os acromiale, which was classified preacromion (3), mesoacromion (20), and meta-acromion (2)...

BACKGROUND: Revision shoulder arthroplasty is a technically challenging procedure. It is associated with increased blood loss and operative time, and it frequently necessitates revision implants, augments, and bone-grafting. Shoulder arthroplasty systems with a convertible-platform humeral stem have been developed to reduce the complexity of revision procedures by eliminating the need for humeral component explantation when converting from anatomic shoulder arthroplasty (hemiarthroplasty or total shoulder arthroplasty) to reverse total shoulder arthroplasty (rTSA)...

Humeral hemiarthroplasty, anatomic total shoulder arthroplasty, and reverse total shoulder arthroplasty all rely on a prosthetic articular surface fixed to the proximal humerus. Humeral implant designs have changed considerably as a result of improved understanding of proximal humeral anatomy and prosthetic biomechanics. Fixed, monoblock implants have been superseded by modular implants with variable inclination, offset, version, and stem length. Press-fit designs now commonly have surface coatings that allow bony ingrowth...

A retrospective review was performed of all shoulder arthroplasties with patients grouped on the basis of transfusion protocol time period. Group 1 had transfusions if postoperative hematocrit was <30. Group 2 had transfusions based on symptomatic anemia. Bivariate analysis of transfusion factors and multivariate analysis of significant bivariate factors were performed. Protocol change decreased transfusion rates from 16% (group 1, 153 arthroplasties) to 8% (group 2, 149 arthroplasties). Reverse shoulder arthroplasty (RTSA) transfusion rate decreased dramatically (from 24% to 5%)...

Proximal humerus fractures in the elderly are increasing in frequency as the population ages. The purpose of this study was to investigate surgical and cost trends in the Medicare population. The PearlDiver database was queried using diagnosis codes to identify Medicare recipients with proximal humerus fractures from 2005 to 2012. Surgical trends, demographics, and charge/reimbursement data were analyzed. There were 750,426 proximal humerus fractures in Medicare recipients during the 8-year period. Eighty-five percent of the fractures were treated nonoperatively; however, the percentage of operative vs nonoperative management increased significantly over time for all fractures, isolated fractures, and fracture dislocations...

Alterations have been made over the years to the standard reverse total shoulder arthroplasty (RTSA) prosthetic components in an effort to decrease adverse events; this has led to the advent of a short humeral stem prosthesis. To the authors' knowledge, there are no reports describing the complication of a traumatic periprosthetic Wright and Cofield classification type A fracture with use of a short metaphyseal humeral stem component for RTSA. The authors describe a 49-year-old woman with this pathology who was treated with open reduction and internal fixation using a proximal humerus locking plate, unicortical and bicortical screw fixation, and a cerclage wire construct without the need to violate the shoulder joint or revise components...

PURPOSE: Have the results of shoulder arthroplasty got better over the last two decades? To answer this question, we sought published evidence that the patient-reported outcomes and re-operation rates have improved in reports of more recently performed anatomic (TSA) and reverse (RSA) total shoulder arthroplasties. METHODS: We analyzed the arthroplasty results among studies published from 1990 to 2015, adjusting for the fact that the different publications presented patient groups with different combinations of diagnoses, used various outcome scales, and had different lengths of follow-up...
