Purpose: Clavicle fractures in the lateral third are associated with more complications. Various methods of internal fixation exist; however, there is no consensus which should be employed. The purpose of this study was to evaluate the outcomes of these various methods in our regional trauma unit. Methods: We performed a retrospective review of patients who underwent internal fixation of a lateral clavicle fracture in our unit between 1 August 2014 and 31 July 2019. Demographic and outcome data were extracted from electronic care records and imaging systems. Results: In total, 44 patients were included, with the following demographics: mean age 26 years, 63.6% male, 65.9% high-energy injury, 68.2% Neer II fracture. The following operations were performed: hook plate fixation (HPF) = 10, locking plate fixation (LPF) = 16, coracoclavicular ligament reconstruction (CCLR) = 12, and LPF + CCLR = 6. Patients having LPF had a significantly larger post-operative coracoclavicular distance (7.6 mm vs 13.5 mm, p < 0.01), and trends towards a lesser decrease in CCD (9.9 mm vs 12.6 mm, p = 0.37) and incomplete ACJ reduction (50.0% vs 89.3%, p = 0.11). There was a significantly higher re-operation rate after HPF (100% vs 23.5%, p < 0.01). There were no differences in time to union or duration of follow-up. Conclusion: In our unit there is no clearly favoured method of internal fixation of lateral clavicle fractures. When LPF is used, there should be consideration of concomitant CCLR. The high rate of re-operation after HPF is concordant with previous research. [ABSTRACT FROM AUTHOR] |
