Which way are the bones rotated in a clubfoot? This question has long been debated by clubfoot surgeons. Opinions have been based on observations from surgery, radiographs, and autopsies. These methods all have pitfalls and are subject to misinterpretation. We used three-dimensional computer modeling to analyze histologic sections of a newborn clubfoot and a newborn normal foot. Relative to the bimalleolar axis in the axial plane, the normal talus demonstrated 5 degrees of internal rotation of its body and 25 degrees internal rotation of its neck. The clubfoot talus showed 14 degrees of external rotation of its body and 45 degrees of internal rotation of its neck. The calcaneus was externally rotated 5 degrees in the normal foot and internally rotated 22 degrees in the clubfoot.
马蹄内翻足的骨骼是如何旋转的？这个问题长期以来一直是马蹄内翻足外科医生争论的焦点。观点基于手术观察、X光片和尸检。这些方法都有缺陷且容易被误解。我们使用三维计算机建模来分析新生儿马蹄内翻足和新生儿正常足的组织学切片。相对于轴向平面内的双踝轴，正常距骨体部有5度内旋，颈部有25度内旋。马蹄内翻足的距骨体部有14度外旋，颈部有45度内旋。正常足的跟骨外旋5度，马蹄内翻足的跟骨内旋22度。
