LEVEL OF EVIDENCE: THERAPEUTIC STUDY, LEVEL IV SURGICAL TECHNIQUE AND RESULTS OF SHOULDER RESURFACE REPLACEMENT IN THE DEGENERATIVE SHOULDER

Abstract

Introduction: Shoulder surface replacement arthroplasty has been established for several decades as a mean to restore comfort and function of the shoulder for many afflictions that derange the normal anatomy. The surface replacement may offer some advantages over the stemmed prostheses.

Purpose: The purpose of the study was to evaluate the clinical and radiological results of Copeland cementless surface replacement arthroplasty (CSRA) applied in patients with a degenerative arthritis.

Patients and Methods: The study was conducted on 76 patients with degenerative joint disease of the shoulder that were operated on between 1999 and 2006. The patients were prospectively followed up clinically and radiologically for a mean of 26.2 months (range, 9–80 months). There were 41 female and 35 male shoulders. The mean age was 64.4 years (range, 54–86). The mean operative time was 42 minutes (range, 27–62 minutes). The clinical assessment was performed with the Constant score Results: The constant score significantly improved from a mean of 16.32 points preoperatively to 68.72 points postoperatively. The average pain score increased from 0.2 points to 10.2 points. The average ROM score increased from 9.22 points to 24.73 points. The humeral offset increased from 24.2mm to 29.2mm.

Conclusion: The shoulder surface replacement arthroplasty shows good mid-term results in patients with degenerative shoulder disease.
