Observations of tarsal disintegration in the cases operated for foot-drop.

Fifty cases operated for foot-drop during the years 1971-82 were called for follow-up. Out of fifty, twenty cases were reported to the hospital. Three cases among the twenty were found to have changes of tarsal disintegration. The changes were found more confined to the talo-navicular junction. X-ray changes both in non-weight and weight bearing were studied. Their line drawings (tracings from actual radiograph) are presented. It is concluded that due attention should be given to the pre-operative evaluation, operative procedure used and post-operative management particularly the weight-bearing and proper footwear.
