目的探讨股骨后外侧入路T形钢板固定治疗儿童股骨干下1/3段骨折的临床疗效。方法28例儿童股骨干下1/3段骨折,均采用股骨后外侧入路T形钢板内固定治疗,随访其临床效果。结果术后随访8～26个月,平均16个月。骨折均愈合,其中优25例,良3例。结论股骨后外侧入路T形钢板固定治疗儿童股骨干下1/3段骨折,副损伤小,固定牢固,髋、膝关节功能恢复理想。 Objective To investigate the clinical effect of posterior femoral trochanteric T-plate fixation for the treatment of 1/3 fracture of the femur shaft in children. Methods 28 cases of children under the femoral shaft 1/3 of fractures were treated with T-plate fixation of posterior lateral femoral approach, follow-up of its clinical effect. Results Postoperative follow-up 8 to 26 months, an average of 16 months. Fractures were healed, of which 25 cases excellent, good in 3 cases. Conclusions The posterior femoral trochanteric T-plate fixation for the treatment of 1/3 fractures of the femoral shaft in children has the advantages of small side injury, firm fixation and satisfactory hip and knee joint function recovery.
