The etiopathogenesis of congenital talipes equinovarus remains mysterious. The authors investigated the role of increased intracompartmental leg pressures as a causal relationship with this deformity by measuring the pressures in 25 children aged between 6 months and 1 year with unilateral talipes equinivarus before surgical release. The deep posterior intracompartmental pressure in the leg with talipes equinovarus was greater than the other compartments, and the deep and superficial posterior intracompartmental pressures were also significantly higher than those of the contralateral normal sides (p < 0.05). There were linear correlations between the posterior intracompartmental pressure of affected legs and the Kite index, tibiocalcaneal angle and talo-first metatarsal angle of the affected legs. Deep posterior intracompartmental pressure is a strong predictor of abnormality in the Kite index. The present study showed a probable causal relationship between increased deep posterior intracompartmental pressure and etiopathogenesis of talipes equinovarus.
先天性马蹄内翻足的病因发病机制仍然不明。作者通过测量25例6个月至1岁单侧马蹄内翻足患儿手术松解前腿部各间隔内的压力，研究腿部间隔内压力升高与该畸形之间的因果关系。患有马蹄内翻足一侧腿部的后深间隔内压力大于其他间隔，后深间隔和后浅间隔内压力也显著高于对侧正常侧（p < 0.05）。患侧腿部后间隔内压力与患侧腿部的凯特定律指数、胫跟角和距第一跖骨角之间存在线性相关性。后深间隔内压力是凯特定律指数异常的有力预测指标。本研究表明后深间隔内压力升高与马蹄内翻足的病因发病机制之间可能存在因果关系。
