摘　　要：目的探讨超声检查在先天性马蹄内翻足(CCF)跟腱检查中的应用价值。方法收集33例CCF患儿,按照病变累及范围分为单侧CCF组(18例)和双侧CCF组(15例);选取同期20名健康婴儿作为对照组。行双足跟腱超声检查,测量自然位、背屈位、跖屈位下的跟腱长度(AL),计算3组自然位与背屈位、自然位与跖屈位、背屈位与跖屈位AL的差值,并进行统计学分析。结果超声发现全部CCF患足跟腱形态及AL异常,自然位时跟腱不平直,中部不同程度凹陷,长度较健足短。双侧CCF组患足与对照组健足、单侧CCF组患足与对侧健足自然位时AL及自然位与背屈位、自然位与跖屈位、背屈位与跖屈位AL的差值均有统计学意义(P均<0.05),背屈位、跖屈位时AL的差异无统计学意义(P>0.05)。结论超声可直观显示CCF患儿不同体位下跟腱形态及AL改变,动态观察并评估患足背屈、跖屈活动异常。Objective To assess the value of ultrasonography in screening of achilles tendon in congenital clubfoot （CCF） children. Methods Thirty-three children with CCF were divided into unilateral CCF group （n= 18） and bilateral CCF group （n= 15） according to the range of lesion involving. Twenty healthy children were selected as the control group. Ultrasonography was performed to both feet in all children. The achilles tendon length （AL） at the neutral position, maximal dorsal flexion and maximal planter flexion position were measured, and then the differences of the neutral position vs dorsal flexion, neutral position vs planter flexion and dorsal flexion vs planter flexion AL （AL-difference） were calculated and compared statistically. Results Deformation of achilles tendon and abnormality of AL were detected with ultrasonography in all clubfeet. In all clubfeet, achilles tendon were not straight in neutral position, the middle part of which were flexure in various degrees, and AL were shorter than that of normal feet. Compared with AL at the neutral position and AL-differ- ence at all position with the normal foot in control group and unilateral CCF group, those of clubfeet in bilateral CCF group and unilateral CCF group were all significantly different （all P-C0.05）. Compared with AL at the maximal dorsal flexion and maximal planter flexion position with normal feet, those of clubfeet were not significantly different （all P〉 0.05）. Conclusion Ultrasonography can visualize the shape of achilles tendon and AL at different positions. Dynamic foot ultra sonography is useful for evaluating the mobility of CCF.
