Charcot like change in leprosy appears only on foot and ankle but not another joint. We found 3 cases of the destruction all over the tarsus, 23 cases on ankle joint, 8 cases on Chopart joint, 4 cases on Lisfranc joint and 7 cases on subtalar joint of 45 joints in totals.
Charcot like change in tarsal bone and ankle joint may be caused by repeated distorsion. Clinical finding shows lateral instability. The sclerosis and deformity of the tarsal bone and the loose bodies in ankle joint are reviewed roentgenologically, but there is rare the proliferation of bone.
In Chopart joint, Lisfranc joint and subtalar joint, a warm swollen ankle is developed without existing cause, and the stability of foot is good.
There are the destruction of the navicular, cuneiforme and calcaneal bones roentgenologically, and these findings show the feature of the leprous osteous osteomyelitis in early stages.
