Aim: To evaluate the results of arthroscopic resection of the superomedial corner of the scapula, using a new superior portal, in patients with painful snapping scapulæ.

Methods: An analysis was made of 10 patients who had each undergone arthroscopic resection of the superomedial corner of the scapula. The patients were evaluated by questionnaire and clinical examination, and the results assessed by the UCLA rating score.

Results: There were four women and six men with a mean age 26.9 years (range: 16 to 40 years). The average duration of symptoms was 53.2 months (range: 12 to 154 months). Their x-rays and CT scans were normal. The average follow-up period was 11.3 months (range: three to 23 months). There were no post-operative complications. The scapulothoracic crepitus disappeared in two patients, decreased in seven patients, and remained the same in one patient. The mean postoperative visual analog pain scale was 2.7. All felt the procedure to be worthwhile. On the UCLA score there were four excellent, four good and two fair results.

Conclusions: Scapulothoracic arthroscopy using medial and superior portals is a safe procedure. Resection of the superomedial corner of the scapula reliably improved symptoms from the painful snapping scapula.
