To evaluate the results of arthroscopic repair for Ideberg Ⅰa glenoid fracture with double-pulley technique.

Between March 2014 and March 2017, 10 patients with Ideberg Ⅰa glenoid fracture were managed with double-pulley technique. Radiographs and CT scan were obtained to further evaluate glenoid fracture before operation. Adequacy of reduction and healing of glenoid fracture were assessed by CT postoperatively at follow-up. The visual analog scale (VAS) for pain score and Rowe score for Ideberg Ⅰa glenoid fracture were compared by rank sum test and t test. The postoperative mean range of motion values and postoperative recurrence rate of shoulder dislocation were also investigated.

Bone union was achieved in all the patients. Ten patients were followed up for (21.0±2.1)months. The VAS score improved from 1 (1, 2) preoperatively to 0.5 (0, 1) at the final follow-up, with no significant difference(Z=-1.583, P>0.05). The mean Rowe score improved from(58±16) to (92±6)at last follow-up (t=6.344, P<0.001). No patients experienced postoperative traumatic dislocations. The values of forward elevation were(171±7)°, external rotation(73±6)°, and the patients could touch thoracic vertebrae T10-T7 at the operated side performing internal rotation. There was no difference in range of motion compared with the contralateral limb. No patient had postoperative infection or other problems related to surgery.

Double-pulley technique is a valuable method for the arthroscopic treatment of Ideberg Ⅰa glenoid fracture.
