Abstract:
PURPOSE: The purpose of this study is to analyze the treatment results and complications in unstable distal clavicle fractures which were treated with a Hook plate, and, in particular, to compare the functional results before and after removal of the Hook plate. MATERIALS AND METHODS: We examined 20 cases in 20 patients who underwent removal of Hook plates after bony union was obtained in an unstable fracture of the distal clavicle (Neer type II) from March 2009 to December 2012. The average follow-up period after initial surgery was 12 months (8-20 months). Plates were removed at 18 weeks (ranged from 10-36 weeks) after initial fixation. University of California at Los Angeles (UCLA) and Korean Shoulder Scoring System (KSS) scores were used for clinical functional evaluation, and plain radiographs were used for radiological evaluation. RESULTS: In radiological evaluation, bony union was obtained at an average of 11.4 weeks (ranged from 8-14 weeks) in all of the 20 patients. All of the 20 patients showed limited range of motion, mild pain, and discomfort of the shoulder before removal of the Hook plate, and all of the 20 patients showed better results in UCLA and KSS score after removal of the plate, when compared to before removal. Stress fracture as a major complication, was united completely with a 'figure of 8' bandage and deep wound infection was resolved after repeated debridement and antibiotic treatment with satisfactory functional results. CONCLUSION: Hook plate in treatment of unstable fracture of the distal clavicle is considered to be a useful method because rigid fixation can be obtained. However, there are some complications, such as limited range of motion, pain, and discomfort of the shoulder joint, before removal of the Hook plate. Therefore, we think that removal of the Hook plate as soon as possible if bony union is obtained would be desirable.
