Abstract
The purpose of this study was to evaluate the clinical results of arthroscopic decompression for paraglenoid labral cysts. We retrospectively evaluated 4 patients (all males) with paraglenoid labral cysts treated by arthroscopic decompression between July 2006 and April 2008. The average age was 36 years (range 21 to 50 years), and the average follow-up period was 11.3 months (range 6 to 18 months). All of the patients had shoulder pain on the handedness side, and 2 had weakness on external rotation and atrophy of the infraspinatus muscle. Preoperative MRI showed cystic lesions adjacent to the spinoglenoid notches in all patients, for whom capsular release was performed under arthroscopy. The symptoms (shoulder pain and muscle weakness) were relieved after the operation in 3 cases. Postoperative MRI showed disappearance of the cysts, and no recurrences. We suggest that paraglenoid labral cysts can be treated successfully by arthroscopic decompression.
