In a prospective study, 20 patients were randomly selected for either open acromioplasty according to Neer or for arthroscopic subacromial + decompression (ASD). All suffered from shoulder impingement for which conservative treatment had been unsuccessful. Functional results after two years were assessed. All patients were assessed radiographically to visualize recurrence of subacromial osteophytes. Functional results in the arthroscopic group are good and similar to those after open surgery. Both methods seem to result in adequate subacromial decompression, including bone resection. The arthroscopic method also has in its favor less operating time, earlier restoration of active range of motion, and reduction in time away from work.
在一项前瞻性研究中，随机选择20例患者，分别接受根据Neer法进行的开放性肩峰成形术或关节镜下肩峰下减压术（ASD）。所有患者均患有肩部撞击症，保守治疗均未成功。评估了两年后的功能结果。对所有患者进行影像学评估，以观察肩峰下骨赘的复发情况。关节镜组的功能结果良好，与开放手术后的结果相似。两种方法似乎都能实现充分的肩峰下减压，包括骨切除。关节镜手术方法还具有手术时间短、主动活动范围恢复较早以及减少误工时间等优势。
