Background: Glenoid fractures of the scapula are rare. With inappropriate treatment, this injury can lead to post-traumatic degenerative joint disease and severe functional impairment. We report the clinical results of treatment of Ideberg typeII-V glenoid fractures of the scapula in our hospital.<BR>Methods: Between June 2005 and June 2011, seven Ideberg typeII-V glenoid fractures of the scapula were treated. There were 1 female and 6 males. The average age was 49.4 years old. There were 2 typeII, 2 typeIII, 1 typeIV, and 2 typeV cases. Indications for the operation included an articular step-off or gap of 5mm or greater, and disruption of superior shoulder suspensory complex(SSSC). The typeIV case was treated conservatively, and the remaining 6 cases were treated operatively. In operation, glenoid fractures and disrupted SSSC were repaired. We evaluated postoperative bone union, range of motion, step-off and gap of articular surface in CT view, and postoperative complications.<BR>Results: All fractures gained bone union. The average range of active elevation, external rotation, and internal rotation were 156.4 degrees, 48.6 degrees, and T10 level, respectively. The average step-off was 1.4mm, and the average gap was 0.8mm. There were no complications.<BR>Conclusion: Clinical results of treatment of Ideberg typeII-V glenoid fractures were satisfactory. In treatment of glenoid fractures, anatomical reduction of the articular surface and reconstruction of SSSC seem to be important.
