AbstractThe purpose of this study was to introduce transradioulnar single Kirschner-wire (K-wire) fixation technique for unstable fractures of both of the distal forearm bones in children and to evaluate the differences in clinical and radiographic results of osteosynthesis between this method and conventional K-wire fixation. Forty-one patients (20 conventional K-wire fixation, 21 transradioulnar single K-wire fixation) were reviewed who underwent a closed or mini-open reduction with K-wire fixation for fractures of both of the distal forearm bones. Their mean age at operation was 10.7 years (range, 8-16 years). Surgical intervention was indicated (1) when in addition to a complete ulnar fracture, the radius showed a 50% of displacement or greater, or 20-degree angulation or greater, (2) when in addition to an incomplete ulnar fracture, the radius was completely displaced, and (3) when reangulation was 15 degrees or greater in any direction at follow-up. The minimum follow-up period was 2 years. Bony union was achieved in both groups at approximately 7 weeks after surgery, and there were no significant differences in the operative time, duration of hospitalization, and duration of external support between the 2 groups. There were no major complications such as nonunion, radioulnar synostosis, premature physeal closure, or redisplacement or reangulation. Transradioulnar single K-wire fixation technique was a relatively simple procedure with comparable outcomes compared with conventional K-wire fixation technique. In addition, physeal injuries could be avoided, and there was no need for passing across the fracture line. Thus, it is suggested that transradioulnar single K-wire fixation technique can be a good alternative method for high-risk fractures of both of the distal forearm bones in children.
