Shoulder arthroplasty in patients with osteoarthritis and dysplastic glenoid morphology.

Abstract

Fifteen shoulders with primary osteoarthritis and dysplastic glenoid morphology underwent shoulder arthroplasty (eleven total shoulder arthroplasties and four hemiarthroplasties). Patients were evaluated at a mean of 37 months after replacement with clinical examination, Constant score, subjective patient opinion, and radiographic examination. One glenoid component was loose, necessitating removal; the remainder of the prostheses were in place at latest follow-up. Significant improvement was observed in Constant score (32 points preoperatively vs 71 points postoperatively) and active mobility (anterior elevation, 89 degrees preoperatively vs 146 degrees postoperatively; external rotation, 7 degrees preoperatively vs 45 degrees postoperatively) after arthroplasty. This study demonstrates that the rare scenario of osteoarthritis coupled with a dysplastic glenoid can be treated successfully with shoulder arthroplasty.
