前肩峰形成術の術後成績の検討

抄録

This is retrospective review of 21 patients who underwent anterior acromioplasty for chronic impingement syndrome. Anterior acromioplasty, described by Neer in 1972, is generally accepted as the procedure of choice for symptomatic subacromial impingement. The shoulders were evaluated postoperatively for pain, ROM muscle strength. Results were graded poor, fair, or good.
The primary diagnosis of shoulder impingement was made by physical examination, positive impingement sign, relief of pain by a subacromial injection of lidocaine, radiographic changes on plain radiographs, arthrography and ultrasonography.
The indication for surgery was lack of pain relief by conservative therapy for two or more months. All of patients had relief of preoperative pain and full or improved motion. Only one patient, who had pseudounion of the postclavicular fracture, was failed because of muscle weakness.
Anterior acromioplasty is a procedure that yields predictably good to excellent results, 95% in this study.
