目的评价切开复位克氏针内固定结合大块植骨治疗失稳性儿童肱骨外髁骨折不愈合的疗效。方法回顾性分析自2010-03—2016-02采用切开复位克氏针内固定结合大块植骨治疗的27例失稳性儿童肱骨外髁骨折不愈合。结果27例获得随访12~60个月,平均18个月。患者肘关节失稳症状消失,肘关节屈伸功能正常或轻度受限,无尺、桡神经损伤表现。骨折愈合时间2~8个月,平均3.5个月。末次随访时27例肘关节HSS评分均达到90分以上,疗效均为优。结论切开复位克氏针内固定结合大块植骨治疗失稳性儿童肱骨外髁骨折不愈合的手术操作难度不大,术后石膏制动并积极有效地进行功能康复锻炼,可以取得满意的治疗效果。
Objective To evaluate the curative effect of open reduction and Kirschner wire internal fixation combined with massive bone graft in the treatment of unstable lateral humeral fractures in children. Methods Retrospective analysis of nonunion of humeral condylar fracture in 27 cases of unstable children treated with open reduction and Kirschner wire fixation combined with bulk bone graft since 2010-03-2016-02. Results 27 cases were followed up for 12 to 60 months with an average of 18 months. Patients with symptoms of elbow instability disappeared, elbow flexion and extension functions were normal or mildly limited, no ulnar, radial nerve injury performance. Fracture healing time 2 to 8 months, an average of 3.5 months. At the last follow-up, 27 patients with elbow joint HSS score reached 90 points or more, the curative effect is excellent. Conclusions Open reduction and Kirschner wire internal fixation combined with large bone graft in the treatment of unstable lateral humeral condyles fracture nonunion surgery operation is not difficult, postoperative gypsum braking and active and effective rehabilitation exercise, you can get satisfactory treatment effect.
