Objective To investigate the efficacy of double plate combined with autogenous bone graft in the treatment of aseptic nonunion of the humeral shaft.Methods From April 2017 to June 2021, 10 cases of humeral diaphyseal nonunion treated with double plate internal fixation combined with autogenous bone graft in Tongji Hospital of Tongji Medical College, Huazhong University of Science & Technology were retrospectively analyzed. There were 7 males and 3 females, aged from 20-68 years, with an average age of 45.1 years. Initial internal fixation included 3.5 mm LCP in 7 cases, 3.5 mm double plate in 2 cases, and intramedullary nail in 1 case. Four cases had internal fixation failure. Weber and Cech nonunion classification: 4 cases were capable of biological reaction and 6 cases were inactive nonunion. Fracture healing was evaluated by X-ray or CT. The main outcome measures were the Mayo Elbow Performance Index and the Constant-Murley score before the operation, 3 months after operation, and at the last follow-up.Results The mean follow-up time was 14 months (range, 10-24 months). All patients healed in an average of 4.7 months without complications. Three months after the operation, the MEPI score was 82.50±10.61, and the Constant-Murley score was 79.60±6.11. At the last follow-up, the MEPI score was 88.50±5.30, and the Constant-Murley score was 86.90±4.12, which were significantly improved compared with preoperative scores.Conclusion Satisfactory results of double plates internal fixation combined with autogenous bone grafting in the treatment of nonunion of the humeral shaft. Double plates fixation can improve the stability of fixation, facilitate early functional exercise and promote fracture healing. |
