Abstract

Purpose: This multicenter, retrospective study aimed to compare clinical outcomes and complications between locking plate fixation and new coracoclavicular (CC) fixation for patients with unstable distal clavicle fracture.

Methods: We included 142 patients in this TRON study. The mean follow-up was 15.5 (6-31) months. The patients were divided into two groups: the locking plate group (Group L) and CC fixation group (Group C). To adjust for baseline differences between the groups, a propensity score algorithm was used to match two groups in a 1:1 ratio. After matching, we compared operation time and the University of California Los Angeles (UCLA) shoulder score at 3 and 6 months postoperatively and at last follow-up as clinical outcomes and the rate of complications.

Results: After matching, 20 cases from each group remained. Operation time was shorter in Group C (75 [22, 111] vs. 100 [38, 120] min; P = 0.023). At 3 months postoperatively, UCLA score in Group C was better, but no significant differences between the groups were found at 6 months and last follow-up after surgery. The rate of complications was not significantly different between the groups.

Conclusion: CC fixation might be equivalent to locking plate fixation in clinical outcome, and the operation time is shorter than that required for locking plate fixation.
