TWO-TAILED TRANSFER OF TIBIALIS POSTERIOR FOR CORRECTION OF DROP-FOOT IN LEPROSY

Abstract

1. The results of thirty-nine operations for correction of drop-foot in thirty-three patients with leprosy are discussed. 2. The procedure used was circumtibial, subcutaneous, two-tailed, tendon-to-tendon transfer of the tibialis posterior to extensor hallucis longus and to extensor digitorum longus and peroneus tertius. The motor slips were inserted into the recipient tendons on the dorsum of the foot. 3. Analysis of the results showed some correlation between the angle of active dorsiflexion and the range ofactive movement ofthe ankle. The angle ofdorsiflexion seemed to determine the range of movement. 4. When contracture of the tendo calcaneus was present, simultaneous lengthening improved the angle of dorsiflexion more than the range of active movement. 5. The causes of failure were sepsis, failure of re-education and unrecognised tightness of the tendo calcaneus. 6. The advantages of the present procedure are mentioned.
