OBJECTIVES: In 1972, Neer reported impingement syndrome of the shoulder and the technique of anterior acromioplasty. We report the results of Neer's acromioplasty and arthroscopic decompression for patients with stage II and III impingement syndrome.
MATERIALS and METHODS: In 12 shoulders of 12 impingement syndro m e,10 anterior acromioplasty (Neer) and 2 arthroscopic decompression were performed. Eleven male and one female were involved. The average age was 38 years (range: 24-56). Four shoulders were classified as stage III impingement syndrome. The follow-up period ranged from 3 to 48months (average: 17.3).
RESULTS and DISCUSSION: In 11 patients followed up for 6 months or more, impingement signs were negative at follow-up. All but one who was a semi-professional pitcher, were satisfied with their results. According to the JOA evaluation system of the shoulder, the average score of postoperative improvement was 16 points. No statistical differences were found between stage II impingement syndrome and stage III. Two patients, treated by arthroscopic decompression, seem to have had the advantage of returning to their previous occupations, early.
