The dyaphyseal nonunion of forearm bones is a complication that changes the normal interaction between radius and ulna, which may lead to forearm malfunction. We reviewed 14 patients treated by surgical technique included a homologous bone graft in combination with a plate. The mean age was 31 years (range, 18-45 years) at the time of surgery. Minimum follow-up was 2 years (mean, 5 years; range, 2-13 years). There were no intraoperative or postoperative complications. At last follow-up, all forearm bones had remodelled. The mean visual analogue pain scale was 1 (range, 0-4). There was a high success rate regarding forearm alignment and functional results; all patients recovered daily and working activities quickly. This surgical technique in treatment of aseptic forearm nonunion by combining homologous bone graft with a plate led to bone healing, improved forearm function, and a durable outcome with long-term follow-up.
