Systematic Review Of Prevalence, Risk Factors, And Management Of Instability Following Reverse Shoulder Arthroplasty, Jeffrey J. Olson, Michael D. Galetta, Rachel E. Keller, Luke S. Oh, Evan A. O'Donnell

Orthopedic Surgery Resident Research

Background

Since its approval for use, reverse shoulder arthroplasty (RSA) has become the primary treatment for cuff tear arthropathy, with indications expanding more recently to include revision fracture, osteoarthritis with significant glenoid bone loss, tumor, and chronic instability. Instability is a well-described postoperative complication, occurring in 1to 31% of relatively small cohorts and case series. Given the relative infrequency of instability, there remains a need for a comprehensive review of instability with a focus on risk factors and management. Our goal of this systematic review is to describe the prevalence, risk factors, and management strategies for instability …

The Modern Use Of The Extended Humeral Head (Cuff Tear Arthropathy) Hemiarthroplasty., Tyler J Smith, Sarav S Shah, Justin W Peterson, Glen Ross

Orthopedic Surgery Resident Research

Today, the treatment of osteoarthritis in the rotator cuff-deficient population is largely dominated by reverse shoulder arthroplasty (RSA). Despite the popularity of and increased familiarity with this procedure, the complication rate of RSA remains significant. An extended humeral head hemiarthroplasty may provide a less invasive alternative for select patients with cuff tear arthropathy (CTA) and preserved glenohumeral active elevation. With the indications for reverse arthroplasty expanding to younger patients, there are concerns about the longevity of this implant, as well as the associated revision burden. In the setting of failed RSA, the bone stock available for glenosphere baseplate fixation can …
