Surgical reconstruction of leprotic foot-drop

We have operated on 25 patients for correction of foot-drop due to leprosy from March 1992 to July 1994. The method used was circumtibial transfer of the tibialis posterior to the tendons of extensor hellucis longus and the extensor digitorum longus in the foot together with lengthening of the Achilles tendon. The results were satisfactory in 20 of these cases as judged by adequate restoration of heel-toe gait and of active dorsiflexion. The follow-up period ranged from 6 months to 2 years. Inadequate post-operative physiotherapy was the reason for unsatisfactory results in five cases.
