Abstract

PURPOSE
To evaluate the result of distal clavicle fracture treated by Hook plate (LCP clavicle hook plate, Synthes(R), Paoli, Switzerland).
MATERIALS AND METHODS
10 patients with distal clavicle fracture treated by Hook plate from April 2008 to March 2010 were analyzed. The average follow-up period was 10 (range 4 to 26) months. The reduction was qualified and evaluated according to the immediate post-operative, final radiographs. We analyze the result by UCLA score and Kona's functional evaluation.
RESULTS
By radiologic evaluation, all cases showed anatomical reduction and solid union. By Kona's functional evaluation, there are 7 cases with excellent results, 3 cases with good results. The UCLA score was average 33.3 (range 29 to 35) points followed by 6 excellent cases, 4 good cases. As complication, 1 case showed post-operative clavicle shaft fracture and 1 case showed acromial osteolysis on X-rays. We found no complications such as skin irritation, infection, loosening of screws, and plate failure.
CONCLUSION
The Hook plate fixation for distal clavicle fracture is considered effective method for satisfactory reduction and rigid fixation, a lower incidence of nonunion and excellent clinical result.
