[Progression towards dislocations of foot bone lesions in leprosy]. / De l'évolution vers la dislocation des lésions osseuses du pied du lépreux.

From a series of 211 tarsal, medio-tarsal and metatarso-phalangeal dislocations, the authors, after having recalled the lesion mechanism, adopted a classification and gave a place to preventive conservative surgery in 52 cases. The early forms can have early limited arthrodesia. The developed lesions present indications of arthrodesia--isolated reconstruction or associated to spongy or cortico-spongy bone grafts. The late forms impose amputation even when the forefoot seems of good bone quality because the metatarsal-phalangial stiffness is the cause for the failure of the Wladimiroff-Mickulicz interventions.
