Introduction:
Reverse total shoulder arthroplasty (RTSA) has revolutionized the treatment landscape for a spectrum of shoulder pathologies, extending its indications from rotator cuff arthropathy to encompass irreparable rotator cuff lesions, fractures, inflammatory arthritis, and tumors. However, the exponential increase in RTSA usage has brought a proportional rise in associated complications, with dislocation being one of the most common early post-operative complications.
Case Report:
This case report details a 65-year-old right-hand dominant male patient presenting with chronic pain and weakness in the right shoulder, diagnosed with advanced glenohumeral arthritis and massive irreparable rotator cuff tears. The patient underwent a Bony Increased- Offset RTSA (BIO-RTSA) procedure, coupled with subscapularis repair. Postoperatively, the patient experienced pain and instability, culminating in an atraumatic anterior dislocation at 4 months. Despite conservative management, recurrent dislocations persisted. Revision surgery was performed with an increase in the linear component size for containment. About 1 year postoperative of the revision surgery, recurrent dislocation reoccurred. Re-revision surgery was performed with secondary pectoralis major (PM) transfer for subscapularis deficiency due to re-tear from recurrent dislocation, and with an increased humeral tray size for better containment. About 1-year and 6-month post-operative to the re-revision surgery, the patient achieved restored stability, improved range of motion, and reported satisfaction with the outcome.
Conclusion:
This case report underscores the challenges of managing recurrent anterior dislocation after RTSA. The successful use of secondary PM transfer highlights its efficacy as a salvage procedure in restoring stability for persistent anterior dislocation after RTSA. Yet, further clinical studies are warranted to establish the role of such interventions in the management for RTSA-associated complications.
