Purpose: The purpose of this study is to compare the clinical and radiological outcomes of two surgical treatments, transacromial pin fixation and hook plate fixation, for unstable distal clavicle fractures. Materials and Methods: Twenty four patients with Neer type II distal clavicle fractures who underwent surgery with transacromial pin fixation (Group I: 12 patients) and hook plate fixation (Group II: 12 patients) were included. Reduction and union were evaluated using plain radiographs. Functional evaluation was performed according to UCLA score and Constant-Murley score at last follow-up. Results: All 24 cases showed bone union. Complete union took an average of 10 weeks for group I and 11.7 weeks for group II. Average UCLA score was 33 (group I) and 32.8 (group II). Average Constant score was 88.5 (group I) and 88.8 (group II). No significant difference for each variable was observed between the two groups. Conclusion: For the surgical treatment of Neer type II distal clavicle fractures, transacromial pin fixation and hook plate fixation are both useful methods.
