Abstract

Purpose
This study evaluated the surgical outcomes of unstable distal clavicular fractures treated with a 2.4 mm volar distal radius locking plate.
Materials and Methods
From August 2009 to August 2012, 16 patients with distal clavicle fractures underwent surgical treatment. Mean age was 36 years (18-62 years) and mean follow-up period was 12.9 months (6-32 months). Two cases were Neer type I, six cases IIa, three cases IIb, three cases III, and two cases V. For the radiologic assessment, union time and metal failure were evaluated, and coracoidiologic assessment, union time and metal failure were evaluatethe acromioclavicular joint. The clinical results were evaluated by range of motion, postoperative complication, and University of California at Los Angeles (UCLA) score.
Results
Mean time to fracture union was 7.4 weeks (6-14 weeks) in all cases. No statistical difference in coracoid-clavicle distance was observed between immediate post-operation group and contra-lateral group (p=0.6), but an increase of 2.1 mm was observed in the last follow up group compared with the contra-lateral group (p<0.01). The UCLA scoring system showed excellent results in 15 cases and good results in one case. Acromial-clavicle instability occurred in one case so that metal removal and distal clavicle resection were performed.
Conclusion
A 2.4 mm volar distal radius locking plate can provide rigid fixation through several screw fixation in the short distal fragment and lead to satisfactory clinical outcomes in unstable distal clavicular fractures.
Key words: Clavicle, Distal clavicle fracture, 2.4 mm volar distal radius locking plate
