Clinical, functional and radiographic outcomes of inverted-bearing reverse shoulder arthroplasty at minimum two year follow-up.

ABSTRACT:

Background

Inverted-Bearing Reverse Shoulder Arthroplasty (IB-RSA) is an alternative reverse bearing construct characterized by an ultrahigh molecular weight polyethylene glenosphere combined with a cobalt-chromium metallic humeral liner. This concept was designed both to minimize bearing wear as well as reduce the potential for scapular notching (SN) seen with more traditional-bearing RSA systems. This study reports on clinical outcomes, functional scores, pain scores, and radiographic incidence of SN in a series of IB-RSA at a minimum of two-year follow-up.

Methods

A retrospective study was conducted on patients who underwent an IB-RSA between 2016 and 2019, with a minimum follow-up period of two years. Patients were evaluated clinically for disabilities of the arm, should
