Bone Block Grafting for Posterior Instability After Anatomical Total Shoulder Arthroplasty: A Case Report.

Abstract

CASE:

A 60-year-old woman with avascular necrosis of the right humeral head underwent anatomical total shoulder arthroplasty (TSA); however, recurrent posterior dislocation occurred 13 months postoperatively. We performed bone block grafting of an autologous iliac crest to the posterior glenoid and posterior capsular plication, after which satisfactory postoperative shoulder function without residual joint instability was achieved.

CONCLUSION:

The presented case had recurrent posterior dislocation after TSA without any abnormal findings in the prosthetic components. Posterior bone block grafting with capsular plication should be considered a viable option for posterior instability after anatomical TSA.
