Shoulder arthroplasty in hemophilic arthropathy

BackgroundCurrently there is little information available on shoulder arthroplasty in patients with painful hemophilic arthropathy. The purpose of this study was to report the results of shoulder arthroplasty in a series of patients, many with long-term follow-up.MethodsThe departmental database was queried for shoulder arthroplasties done in patients with painful hemophilic arthropathy from 1977 to 2007. Seven shoulder arthroplasties (6 patients) were followed clinically for an average 13.8 years (range, 33-323 months).ResultsPain relief was achieved in 5 patients (6 shoulders). Average postoperative elevation was 131°. Average postoperative external rotation was 40°. Average postoperative internal rotation was to lumbar 4. Based on the modified Neer score there were 2 excellent, 4 satisfactory, and 1 unsatisfactory results. None of the shoulders required revision or reoperation. One patient developed a transient brachial plexus neuropraxia which resolved.ConclusionThe results of shoulder arthroplasty in hemophiliacs with painful shoulder arthropathy are moderate and require significant preoperative planning and the support of a hematologist.
