Subjects of this study were 45 patients with 56 idiopathic congenital clubfeet (34 boys with 42 feet and 11 girls with 14 feet) who underwent successful conservative treatment. Radiologic examinations were performed at intervals of 3 months. In anteroposterior radiographs of bilateral feet, the period of appearance of the ossification center was observed for the first, second, and third cuneiform and the tarsal navicular. The ossification of the tarsal bones in the congenital clubfeet occurred later than that in the unaffected feet in boys. The difference between the clubfeet and the unaffected feet was particularly statistically significant for the tarsal navicular and the second cuneiform (p < 0.01). The tarsal naviculars, the first cuneiforms, and the second cuneiforms in clubfeet and in unaffected feet started to be ossified significantly earlier in girls than in boys. Ossification occurred out of order in three of 56 clubfeet and three of 34 unaffected feet.
本研究的对象为45例患有56只特发性先天性马蹄内翻足的患者（34名男孩，42只脚；11名女孩，14只脚），他们均接受了成功的保守治疗。每隔3个月进行一次放射学检查。在双侧足部的前后位X线片上，观察第一、第二和第三楔骨以及足舟骨骨化中心的出现时间。先天性马蹄内翻足中跗骨的骨化比男孩未受影响的足部出现得晚。对于足舟骨和第二楔骨，马蹄内翻足与未受影响的足部之间的差异在统计学上尤为显著（p < 0.01）。女孩马蹄内翻足和未受影响的足部的足舟骨、第一楔骨和第二楔骨开始骨化的时间明显早于男孩。56只马蹄内翻足中有3只以及34只未受影响的足部中有3只出现了骨化顺序紊乱的情况。
