title: Correction of equinus deformity following midtarsal amputation by tibiotalar arthrodesis: a case report.
abstract: Transtarsal amputation in a 49-year-old man was unacceptible because of associated equinus deformity of the ankle and callus formation on the sole of the foot. The equinus deformity and callus formation were corrected by fusion of the ankle in 10 degrees of dorsiflexion and advancement of the talus and os calcis anteriorly. The operation produces a larger weight-bearing area than Syme's amputation, does not disturb the normal weight-bearing fat pad underneath the os calcis, and preserves the length of the extremity as well as the motion in the subastragalar joint.
