BACKGROUND
The purpose of this study is to report outcomes of transphyseal screw hemi-epiphysiodesis at the medial malleolus for the treatment of valgus ankle deformity.
METHODS
An institutional review board-approved retrospective review was done of 24 patient charts. Lateral distal tibial angle (LDTA) was measured preoperatively and at final follow-up.
RESULTS
The average change in LDTA was 8.3 degrees (SD 4.9 degrees; range 0-19 degrees). The average rate of correction was 0.4 degrees per month (SD 0.3; range 0-1.4).
CONCLUSION
Medial malleolar transphyseal screw hemiepiphysiodesis is a simple, effective, and safe treatment for valgus ankle deformity in skeletally immature children.
LEVEL OF EVIDENCE
Level IV, case series.
背景
本研究的目的是报告经骨骺螺钉半骨骺阻滞术治疗内踝外翻畸形的疗效。
方法
对24例患者的病历进行了机构审查委员会批准的回顾性研究。术前及末次随访时测量胫骨干骺端外侧角（LDTA）。
结果
LDTA的平均变化为8.3度（标准差4.9度；范围0 - 19度）。平均矫正率为每月0.4度（标准差0.3；范围0 - 1.4）。
结论
经骨骺螺钉半骨骺阻滞术是治疗骨骼未成熟儿童内踝外翻畸形的一种简单、有效且安全的方法。
证据级别
IV级，病例系列。
