Purpose: To report on the complications of hook-plate fixation for distal clavicle fractures.
Materials and Methods : Eighteen patients who underwent surgery for distal clavicle fracture with a hook-plate from April 2008 to April 2011 were enrolled with a minimum of 4 months follow-up. The reduction was qualified and evaluated according to the radiologic findings. We analyzed the results by UCLA score, Kona’s functional evaluation, and VAS pain score.
Results: By radiologic evaluation, 17 of 18 cases showed anatomical reduction and solid unions. Although satisfactory results were found in the clinical study as shown by the UCLA score, Kona’s functional evaluation, and VAS pain score, complications arose in 7 cases, including osteolysis of the acromion in 2 cases, nonunion in 1 case, periprosthetic fracture in 2 cases, subacromial pain in 1 case, and skin irritation in 1 case. 2 cases of all required reoperation.
Conclusion: To reduce the complications of the hook-plate, a precise surgical technique and the choice of an appropriate size for the hook-plate are needed. We suggest that early removal of the plate is necessary to decrease the risk of subacromial impingement and erosion in hook-plate fixation.
