Comparison of Hybrid Fixation to Dual Plating for Both-Bone Forearm Fractures in Older Children

When operative stabilization of forearm fractures in older children is necessary, the optimal method of fixation is controversial. This study compared the radiographic and functional outcomes of dual plating to a hybrid fixation construct with elastic intramedullary nailing of the radius and plate fixation of the ulna of forearm fractures in children aged between 10 and 16 years. Nineteen patients were treated using a hybrid fixation construct and 13 patients were treated with dual plating fixation. The 2 groups were compared retrospectively according to perioperative data and patient outcome measures. The hybrid fixation construct group had 19, with a mean age of 13.3 years (range, 10-16 years) and the dual plate group had 13 patients, with a mean age of 12.9 years (range, 10-16 years). Groups were similar for sex, arm injured, and fracture location. Duration of surgery and tourniquet use was significantly shorter in the hybrid fixation construct group. There was no significant difference in either time to union or Price scores for function evaluation between the 2 groups. Complication rates were also similar between groups, with 1 ulna delayed unions, 1 superficial infection at entry of nail in hybrid fixation construct group, and 1 ulna delayed unions in the dual plating group. Hybrid fixation, using open reduction and internal fixation with a plate-and-screw construct on the ulna and closed reduction and elastic intramedullary fixation of the ulna, is an acceptable method for treating both-bone diaphyseal forearm fractures in skeletally immature patients aged 10-16 years.
