8字钢板法治疗儿童下肢成角畸形

Correction of angular deformities of the leg in children by 8-plate

[目的]下肢膝内外翻是儿童常见的疾病，临床上可引起膝痛、髌骨与股骨不稳定、步态异常和奔跑困难，这篇文章目的是探讨8字钢板法治疗儿童膝内外翻的临床效果。[方法]34例病人用8字钢板骨骺生长控制法治疗儿童下肢成角畸形。[结果]总结34例病人65膝，其中男16例，女18例；年龄18个月～17岁。通过比较得知股骨胫骨角（femoral tibial angle，FTA）及力线轴与膝关节中心线距离均得到改善，术后随访6～18个月无骨骺损伤。[结论]总结认为膝关节畸形可引起膝前痛及步态问题，8字钢板法安全、有效，操作简单，比截骨矫治风险低、病人痛苦小。

[ Objective] The genu varum and vulgum are common diseases in children, it may cause anterior knee pain, patellofemoral instability, abnormal gait and difficulty running. The purpose of the study is to evaluate and discuss what we consider to be an ideal treatment protocol using method of 8-plate. [ Method] A series of 34 children with angular deformities have been treated by 8-plate epiphyseal reversible method of growth alteration. [ Result ] We received 34 patients （ 65 knees ） , there were 16 boys and 18 girls, age was from 19 months to17 years. Clinical evaluation included measurement of the anatomic femoral tibia] angle （ZrA） and distance between mechanical axis and the knee central. [ Conclusion] C, enu deformity may cause anterior knee pain and gain problems, 8-plate is safe and effective, with no premature physeal closures in our series followed up in 6 - 18 months. The procedure, which is well tolerated, simple, obviates the need for corrective femoral or tibial osteotomie, with lower risk.
