Retrospective study of scapular notches in reverse shoulder arthroplasties.
We conducted a retrospective study of 36 patients with reverse shoulder prostheses to assess whether placement of the glenoid component affected development of scapular notches. Minimum follow-up was 2 years. Glenosphere position and its relation to scapular notching was analyzed radiographically. The glenosphere overhung the inferior glenoid rim in 19 cases (52.8%) and was flush with the rim i...
متن کاملInferior glenosphere placement reduces scapular notching in reverse total shoulder arthroplasty.
Scapular notching is a common complication after reverse shoulder arthroplasty and has been associated with poor clinical outcomes. Factors associated with notching include neck shaft angle and glenosphere position. The goal of this study was to evaluate the incidence of notching with an eccentric glenosphere that allows for inferior offset as well as its effect on clinical outcome. The charts ...
متن کاملProsthetic design of reverse shoulder arthroplasty contributes to scapular notching and instability
AIM To evaluate whether implant design, glenoid positioning, and other factors influenced instability and scapular notching in reverse total shoulder arthroplasty. METHODS We retrospectively reviewed records of patients who had undergone reverse total shoulder arthroplasty by the senior author from July 2004 through October 2011 and who had at least 24 mo of follow-up. The 58 patients who met...
متن کاملInfraglenoidal scapular notching in reverse total shoulder replacement: a prospective series of 60 cases and systematic review of the literature
BACKGROUND The impact of infraglenoidal scapular notching in reversed total shoulder arthroplasty (RTSA) is still controversially discussed. Our goal was to evaluate its potential influence on subjective shoulder stability and clinical outcome. We hypothesized that subjective instability and clinical outcome after implantation of RTSA correlates with objective scapular notching. METHODS Sixty...
متن کاملScapular Notching on Kinematic Simulated Range of Motion After Reverse Shoulder Arthroplasty Is Not the Result of Impingement in Adduction
Impingement after reverse shoulder arthroplasty (RSA) is believed to occur from repetitive contact in adduction between the humeral component and the inferior scapular pillar. The primary purpose of this biomechanical study was to confirm the presence of different types of impingement and to examine which daily-life movements are responsible for them. A secondary aim was to provide recommendati...
