Complications occur with total shoulder arthroplasty (TSA), and they can be daunting to diagnose and treat. It is important to review common TSA-related complications and to summarize risk factors along with causes of these complications and how to avoid them. The orthopaedic surgeon should be knowledgeable about how to successfully manage complications to achieve good patient outcomes and the etiologies and management of the painful and stiff shoulder arthroplasty, subscapularis failure after anatomic TSA, instability after reverse shoulder arthroplasty, and acromion stress fractures in the setting of reverse TSA.

Background: Periscapular fractures, specifically acromial and scapular spine fractures, have been identified as one of the leading complications of reverse total shoulder arthroplasty (rTSA). However, very little is known of the etiology of these postoperative fractures, or how variations in humeral designs correlates with the risk of postoperative fracture development. Therefore, the purpose of this study was to analyze the prevalence, timing, and relationship of humeral component design to acromial or scapular spine fractures.

Since the original Grammont design of a reverse shoulder arthroplasty there has been a trend to decrease inclination angle from 155° to 145 or 135°. Furthermore, lateralization on the glenoid side has been advocated. These changes decrease the risk for impingement between humerus and the inferior part of the glenoid (notching).

Case Report: We present a 64year-old woman with previously known cuff arthropathy (2012/53yo). She fell in 2017 (58 years old with minor shoulder disability) before dislocating the shoulder in 2020 (60 years old) with evidence of a medial Levy-type III scapular spine fracture non-union and severe apprehension, unable to anterior elevate her arm more than 90°.
Increased Deltoid and Acromial Stress with Glenoid Lateralization and Onlay Humeral Stem Constructs in Reverse Shoulder Arthroplasty.

Department of Orthopedics and Rehabilitation, The University of Iowa, Iowa City, USA.
Background: Reverse shoulder arthroplasty (RSA) designs include multiple options for glenoid component lateralization, and humeral component lateralization and distalization (inlay/onlay constructs). The influence of combined glenoid lateralization, and humeral distalization on acromial and deltoid stresses is not well understood. The purpose of this study was to evaluate changes in deltoid and acromial stresses with variations in glenoid lateralization, and with inlay versus onlay humeral components in RSA.
