Painful arc syndrome has been recognized as one of the chronic disability of the shoulder. Usually in Japan, however, clinicians have included it in periarthritis of the shoulder. We have performed the Neer's anterior acromioplasty on twenty-three patients who had been resistive to conventional conservative treatment and had severe disability in daily life. An attempt was made to indentify the site of origin of pain by injection of 1% lidocaine and by bursography and arthrography. This time, twenty patients were followed. The tentative plan of evaluation of the shoulder function (by the Jpanese Ortopaedic Association) was used in assesment of the patients over a half year postoperatively. The mean point was 77 preoperatively, and 95 postoperatively. All but one patient were relieved from symptoms and none of patients have weakening of the leverage of the deltoid muscle. Usually, we divided only the coraco-acromial ligament for athletes when the ligament was a main origin of pathology.The procedure was very simple and period of aftertreatment was short. So we considered this procedure to be usuful for the athlete.
