Abstract
Pain following total shoulder arthroplasty or humeral hemiarthroplasty is uncommon. Impingement syndrome can be an infrequent source of pain following shoulder arthroplasty. We retrospectively reviewed six patients with refractory impingement syndrome treated with arthroscopic acromioplasty following either total shoulder arthroplasty (four patients) or humeral hemiarthroplasty (two patients). Chronic impingement syndrome requiring acromioplasty affected 3% of all patients who underwent total shoulder arthroplasty or humeral hemiarthroplasty during the study period. A thorough history, physical examination, and radiographic findings made the clinical diagnosis of impingement syndrome. All six patients had positive impingement signs and a positive impingement test with subacromial lidocaine injection. Preoperative radiographs revealed a type II or III acromion and subacromial outlet narrowing in five of six patients. Other sources of shoulder pain including prosthesis loosening, infection, and rotator cuff tear were ruled out preoperatively by physical examination and radiographic findings, and were confirmed by arthroscopic examination. The results of arthroscopic acromioplasty were a reduction in pain from 7.5 preoperatively to 1.6 postoperatively, on a scale from 0 to 10. Five of six patients were completely satisfied with the results of their arthroscopic surgery. Overall, according to the University of California at Los Angeles end-result score, the results were rated as excellent or good in five patients, and unsatisfactory in one patient. Arthroscopic acromioplasty can be a successful technique for the treatment of chronic impingement syndrome following total shoulder arthroplasty or hemiarthroplasty in appropriate patients.
