我们定义了脚和踝关节相对于中立位置的运动。使用了13个正常的新鲜冷冻的人足标本。将足部置于旋前、旋后、背屈和跖屈的极端位置，并使用磁性跟踪装置同时监测多个骨骼的位置，以确定在各种条件下距小腿、距下、跖骨-舟骨和距舟关节的旋转。在旋前时，大多数旋转发生在跖骨-舟骨水平，其次是舟骨-距骨、距骨-胫骨和跟骨-距骨水平。旋后时，大多数旋转发生在舟骨-距骨水平，其次是跟骨-距骨、距骨-胫骨和跖骨-舟骨水平。背屈时，大多数旋转发生在距骨-胫骨水平，其次是舟骨-距骨、跟骨-距骨和跖骨-舟骨水平。在跖屈时，大多数旋转发生在距骨-胫骨水平，但在舟骨-距骨、跖骨-舟骨和跟骨-距骨水平也有相当大的运动。了解足部和踝关节在不同位置发生的特定关节运动是很重要的，因为关节活动度的测量可以帮助建立诊断，监测临床状况，确定手术治疗的适应症，评估治疗结果，以及跟踪康复进展。
We defined foot and ankle motion with respect to the neutral position. Thirteen normal fresh-frozen specimens of the human foot were used. The foot was placed in the extreme positions of pronation, supination, dorsiflexion, and plantar flexion, and positions of multiple bones were monitored simultaneously with a magnetic tracking device to determine rotation of the talocrural, subtalar, metatarsal-navicular, and talonavicular joints under the various conditions. In pronation, the most rotation occurred at the metatarsal-navicular level, followed by the navicular-talar, talar-tibial, and calcaneal-talar levels. In supination, most rotation occurred at the navicular-talar level, followed by the calcaneal-talar, talar-tibial, and metatarsal-navicular levels. In dorsiflexion, most rotation occurred at the talar-tibial level, followed by the navicular-talar, calcaneal-talar, and metatarsal-navicular levels. In plantar flexion, most rotation occurred at the talar-tibial level, but there was considerable motion at the navicular-talar, metatarsal-navicular, and calcaneal-talar levels. Understanding the specific joint motions that occur with various positions of the foot and ankle is important because measurements of joint mobility may assist in establishing diagnoses, monitoring clinical conditions, determining indications for operative treatment, assessing results of treatment, and following the progress of rehabilitation.
