Failure of a Reverse Total Shoulder Arthroplasty with a Broken Humeral Stem Tray: A Case Report

INTRODUCTION: The evolution of prosthesis design has increased the frequency of RTSA procedures across various indications. This rise in surgeries has also led to a growing number of associated complications. This case report highlights an unusual occurrence: a mechanical failure of a RTSA at the humeral stem tray. CASE REPORT: A 55-year-old male patient was admitted to our hospital with a sharp pain after 2 years of his initial reverse total shoulder arthroplasty (RTSA) surgery. A broken humeral stem of the RTSA was diagnosed on the plain radiography and the patient underwent a one-stage revision. Further complications have not arisen during his follow-up to date and the patient has a nearly full range of motion. CONCLUSION: Although a humeral stem tray failure is a rarely seen complication for shoulder arthroplasty, surgeons who have used this model prosthesis should be aware that they may encounter such a complication.
