目的 分析大龄儿童桡骨颈骨折受伤后对上肢功能影响,评价大龄儿童Salter-Harris Ⅱ型桡骨颈骨折钢板内固定治疗的疗效.方法 对采用T型钢板内固定治疗的16例大龄儿童桡骨颈骨折临床资料进行回顾性分析.16例均为闭合性骨折,合并桡神经损伤1例,伴有肱骨远端骨折3例,合并有肋骨骨折1例,均为Salter-Harris Ⅱ型骨折,均采用切开复位钢板内固定治疗.结果 16例患儿均获得随访,时间9～18个月.X线愈合时间6～9周,平均7.6周;无畸形愈合及不愈合病例,无骨骺损伤,1例出现钢板阻挡旋后障碍,旋前均大于90°,旋后均大于60°,均无桡神经损伤情况,评定结果为优.结论 对于大龄儿童桡骨颈Salter-Harris Ⅱ型骨折进行切开复位钢板内固定治疗的临床效果满意,不仅增强术后骨折稳定性,而且可更早期进行肘关节功能练习,预防功能障碍的发生率.“,”Objective To analyze the influence of radial neck fracture on the upper limb function in older children,and to evaluate the curative effect of plate fixation in the treatment of Salter-Harris Ⅱ type of radial neck fracture.Methods The clinical data of 16 older children with radial neck fractures who treated by T plate internal fixation were retrospectively analyzed.16 cases were closed fractures,merging radial nerve injury in 1 case,3 cases of distal humerus fractures,1 case with rib fractures,fractures were Salter-Harris Ⅱ type,adopt steel plate internal fixa tion.Results 1 6 patients were followed up for 9-1 8 months.X-ray healing time was 6-9 weekson average 7.6 weeks.No malunion and no healing,no case of epiphyseal injuries.1 patient appeared steel block forearm supination.Postoperative patients with forearm pronation were greater than 90° supination were greater than 60 °.No radial nerve injury.Evaluation results were good.Conclusion Clinical treatment effect of open reduction and plate internal fixation in the treatment of older children with Salter-Harris Ⅱ type of radial neck fracture is satisfactory.Surgical treatment not only can enhance the fracture stability,but also can do the elbow joint function exercise to prevent dysfunction much earlier.
