Modified Spring Plate for Treatment of Unstable Distal Clavicle Fractures

Abstract

Purpose: Unstable distal clavicle fractures should be treated surgically but may be difficult in firm fixation because of small distal fragment. Although a variety of fixation methods have been currently used, none of the methods seem to be firm fixation and little pain. We present a new technique using a spring plate which was modified from one third tubular plate and report the early results. Materials and Methods: Modified spring plate was made from one third tubular plate and the distal hole of the plate was cutting and sharpened by rasp. The sharp edge was bent just like an animal claw (C shape). Between May 2007 and June 2009, a total of six patients with distal clavicle fracture were treated using modified spring plate. A sling was applied in the immediate post operative period for six weeks and exercises were started immediately. Results: Union was achieved in all cases with excellent results without complication (mean Constant score, 96). All patients had returned to ordinary daily activities but mild limitation of abduction (150 o ) by seven weeks after surgery. After six months, the plate was removed. Conclusion: The modified spring plate has provided stable fixation for unstable distal clavicle fixation without disturbance to the acromioclavicular joint, subacromial space, or rotator cuff.
