title: [Talo-crural migration of a Kuntscher tibial nail: a case report].
abstract: Centromedullary nailing without locking using a Kuntscher nail remains a routine practice in developing countries for the treatment of leg fractures. We observed a distal transplantar migration of this type of nail which had not been removed and report here the etiopathogenic factors involved as well as the clinical evolution. In our patient, transplantar migration was favored by mechanical phenomena related to microtrauma caused by the tip of the nail which eroded bony structures of a limb highly solicited for nearly 16 years.
