We have performed on arthroscopic reconstruction by reposition of bony fragment for acute anterior glenoid fracture. The purpose of this study was to evaluate the clinical results of this procedure and to compare them with open methods. We treated 10 acute anterior glenoid fractures by arthroscopic reconstruction. (males 9, female 1; mean age 23 years old). The mean follow up period was 20 months. Bony fragment was repositioned and fixed by suture anchor. Clinical results were evaluated according to the Japanese Orthopaedic Association's score (JOA score) and JSS Shoulder Instability Score (JSS-SIS). The translation of bony fragment was evaluated by CTs and 3DCT images. The average postoperative JOA score was 88 points, ranged from 76 to 100 points. The average postoperative JSS-SIS was 91 points, ranged from 82 to 100 points. There was no case that had apprehension, shoulder instability and severe limitation of range of motion in external rotation. The gap between the bony fragment and the glenoid surface was 1.9mm (from 1 to 6mm), but all cases gained a bone union. Clinical results of arthroscopic reconstruction of acute anterior glenoid fracture were satisfactory the same as the open method.
