Lambeau hétéro-digital selon le principe du « doigt banque » prélevé chez un orteil dupliqué pour le traitement d’un flessum cutané d’une clinodactylie associée

INTRODUCTION: The correction of cutaneous deficiency encountered in clinodactyly is an important aspect of its treatment. The use of the skin lining of an adjacent duplicated toe as a > flap may be of interest in providing good quality tissue. CLINICAL CASE: We report the case of a child with complete duplication of the 5th toe associated with clinodactyly. The use of a heterodactyl flap taken from the amputated toe allows the release of a plantar cutaneous flange of the preserved toe. DISCUSSION: The concept of > flap is mainly used in hand surgery in traumatic lesions of the fingers. Its application in the treatment of clinodactyly on the occasion of the regularization of a polydactyly is also interesting because some fingers or toes are intended to be amputated to render a classical anatomy of five-toed foot. It is necessary for the realization of this type of flap on malformative toes to verify the existence of a distinct viable pedicle of the amputated toe, which can be done only intraoperatively. CONCLUSION: The surgery for congenital malformations of the toes requires perfect management of the skin capital. The use of a > toe flap taken from the toe to be amputated is a viable solution for the treatment of a cutaneous flessum encountered in a clinodactyly of the adjacent finger.
