Overview
Brief Summary
The investigators propose to test the hypotheses that compared with Hook Plate (HP), Locking Plate (LP) reduces the postoperative complications and leads to a better functional recovery after unstable distal clavicle fractures (Neer 2b).
Detailed Description
Controversy exists regarding the optimal treatment for patients with unstable distal clavicular fractures (Neer 2b). The recognized treatment alternatives are Hook plate.Notably, criticisms on this fixation method also appeared and the potential risks of hook migration, loosening, subacromial impingement or rotator cuff injury, and acromial osteolysis were still unsolved. Recently, Herrmann et al.and Largo et al.stabilized the distal clavicle with Locking plate (LP) and these studies offered encouraging support for LP. Because of small sample size (27 patients) and nonrandomization, the convictive power of these researches is not strong enough.
