Abstract

Introduction Since the introduction of reverse total shoulder arthroplasty (RTSA) in 2004, the total incidence of primary total shoulder arthroplasties in the United States has doubled to over 30 cases per 100,000 persons.1,2 Despite overall complication rates decreasing with the advancement of novel techniques and implant designs, there are rising concerns regarding the frequency of certain complications including glenohumeral instability, rotator cuff tearing, and periprosthetic fracture.3,4 Glenoid fractures are relatively rare, occurring at a rate of 1.4% in one national registry study.19,20 The risk of periprosthetic humeral fracture, however, is of particular concern because of how devastating it can be for patients. Humeral fractures following TSAs can occur perioperatively or postoperatively and can be difficult to manage.5 Although they are rare in occurrence, with a reported incidence between 0.6% to 3%, the rise in expected demand for shoulder replacements will require orthopedists to optimize treatment strategies in an aging population to maintain patient outcomes.3,6,7 As such, this review aims to detail the treatment approaches for periprosthetic humeral shaft fractures following TSA, with hopes of better-informing clinicians on how to counsel patients afflicted by this complication.
