BACKGROUND The complications of reversed total shoulder arthroplasty (RTSA) requiring an additional intervention, their treatment options and outcome are poorly known. It was therefore the purpose of this retrospective study, to identify the reasons for revision of RTSA and to report outcomes. METHODS Four hundred and forty-one performed RTSA implanted between 1999 and 2008 were screened. Six...

Background: Total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RTSA) are effective treatments for glenohumeral arthritis and rotator cuff arthropathy. Purpose: To determine if the use of a post operative closed-suction drain following TSA and RTSA affects hemoglobin levels, clinical outcomes, and complications. Hypothesis: Patients who did not receive a drain will have l...

BACKGROUND Controversy surrounds the role of the sub- scapularis (SSC) in reverse shoulder arthroplasty (rTSA) and the need for repair, if possible, at the conclusion of the procedure. QUESTIONS AND PURPOSE: Some investigators have concluded that an intact SSC is critical for stability; others have found no such correlation. What factors should be part of the decision-making matrix on SSC manag...

Spontaneous avulsion of the deltoid muscle in cuff tear arthropathy is extremely rare and represents a challenge for reconstruction.13,24 In such cases, primary repair combination with reverse total shoulder arthroplasty (RTSA) may be at risk failure, as prosthesis’s success relying on functionally elongated deltoid.7,8 Owing to elongation during RTSA, reconstruction under high tension prone fa...

The real-time scheduling advisor (RTSA) is an entirely userlevel system that an application running on a typical shared, unreserved distributed computing environment can turn to for advice on how to schedule its compute-bound soft real-time tasks. Given a list of hosts, a description of the CPU demands of the task, the deadline, and a confidence level, the RTSA will recommend one of the hosts a...

We report the case of a 70-year-old male with Parkinson's disease (PD) and recurrent traumatic left shoulder dislocations. This case is rare because (1) he had a massive irreparable rotator cuff tear and end-stage arthritis (i.e., rotator cuff-tear arthropathy) of the same shoulder and (2) his shoulder was ultimately reconstructed with a reverse total shoulder arthroplasty (RTSA). His first dis...

UNLABELLED Reversed total shoulder arthroplasty (RTSA) has well known indications and good to excellent results are described in the literature. When the arthroplasty fails however, revision remains a technical challenge with many questions unanswered. To analyse retrospectively and consecutively the indications and results of primary RTSA-revision. All patients that underwent revision RTSA bet...

INTRODUCTION Indications for anatomic (aTSA) and reverse (rTSA) total shoulder arthroplasty are well defined and dependent on the function of the rotator cuff; however, indications for rTSA have gradually extended to complex fractures, revisions, and primary arthritis in very elderly patients. The risk of secondary rupture of a weakened or degenerative rotator cuff is difficult to assess and ca...

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 wer...

Reverse total shoulder arthoplasty (RTSA) is commonly used in patients with cuff tear arthropathy (CTA) to relief pain and to restore active humeral elevation ROM [1]. The reverse prosthetic designs medialise the humeral centre of rotation increasing the Deltoid moment arm and its performance [2]. However, clinical studies have shown that patients with RTSA usually show poor humeral internal/ex...
