Functional Results of Unstable (Type 2) Distal Clavicle Fractures Treated with Superior Anterior Locking Plate

Background: The treatment of distal clavicle fracture is always a challenge, as it is mostly unstable and has higherrate of delayed union, malunion, non-union and associated acromioclavicular arthritis. So the management of thesefractures remains controversial. The purpose of this study is to evaluate the functional results of Type 2 distal endclavicle fractures treated with superior anterior locking plate.Methods: From June 2011 to August 2015 a retrospective study of12 male patients (mean age of 41.3 years) 11 withunilateral and 1 with bilateral distal clavicle fractures treated with superior anterior locking plate was done. They wereevaluated at regular intervals with mean follow up of 14 months(12-18 months).Those with minimum one year followup were included in our study. All were evaluated for the functioning of the shoulder joint by both Oxford shoulder scoreand Quick DASH scores, rate of bone union, complications and earliest time for return to work.Results: All fractures union seen within 6-8 weeks (mean time: 7.1 weeks).All had good shoulder range of motion. Theaverage oxford shoulder and Quick DASH score were 46.2 and 6.5.There were no major complications in our studyviz. non-union, plate failure, secondary fracture. But one patient had superficial wound infection. All patients returned towork within 3 months of postoperative period.Conclusion: Displaced distal clavicle fractures treated with superior anterior locking plates achieved excellent resultsin terms of bony union with rarely any complications and demonstrate promising results with this novel technique.
