Open Reduction and Internal Fixation in Treatment of Ideberg Ⅲ Glenoid Fracture

Abstract：Objective To explore the surgical treatment of Ideberg type Ⅲ glenoid fractures. Methods The clinical out-comes of 10 cases(one case associated with acromion and lateral clavicle fracture,one with acromion and humeral tuberosity fracture,six with type ⅡA、acromioclavicular joint injury and two with type Ⅲ)of Ideberg type Ⅲ glenoid fractures treated surgically were retrospectively analyzed. The glenoid fractures were open reduced and fixed with metacarpal plates or cannulat-ed screws through an anterior approach . Results 8 patients with Ideberg Ⅲ fractures were followed up with an average of 20. 1 months. The mean Constant score was(91. 9 ± 5)% in compare with that of the contralateral shoulders. The mean UCLA score was(91. 9 ± 5)% points. At the latest visiting,the mean anterior flexion of affected shoulder was(150 ± 21. 4)°,the mean external rotation was(150 ± 21. 4)°and the mean internal rotation were reached to T9 ± 3 respectively. Conclusion Ideberg Ⅲ glenoid fractures can be successfully treated by open reduction and internal fixation through an anterior approach. The glenoid fractures and the injured SCCC should be treated simultaneously.
