ObjectiveTo evaluate the technique and effectiveness of dual plates fixation for distal comminuted clavicle fractures. MethodsBetween January 2011 and September 2012, 16 patients with distal comminuted clavicle fractures were treated with dual plates fixation. There were 9 males and 7 females with the mean age of 53.6 years (range, 36-71 years). All the patients had closed fracture, including 10 cases of Craig Ⅱ/type Ⅱ, 5 cases of Craig Ⅱ/type V, and 1 case of Craig Ⅱ/type Ⅱ and Craig Ⅲ, which was caused by traffic accident in 8 cases, by sports in 5 cases, and by falling from height in 3 cases. The average interval from injury to surgery was 48 hours (range, 12-72 hours). The X-ray films were taken during follow-up. The functional recovery of the shoulder joint was assessed using the American Shoulder and Elbow Surgeons (ASES) rating scale score. ResultsAll the patients were followed up 13-17 months (mean, 13.6 months). The X-ray films showed bone union and anatomical reduction in all cases, with the mean time of bone healing of 5.6 months (range, 4-6 months). No complication of implant related fracture, implant failure, malunion, nonunion, or post-traumatic arthritis occurred during follow-up. The mean ASES score was 91 (range, 86-93) at last follow-up. ConclusionDual plates fixation in the treatment of distal comminuted clavicle fractures can obtain a rigid fixation and avoid the interference of acromioclavicular joint and shoulder joint activities, so this technique is a safe and effective method.
