[Toe transplantation in congenital malformations of the hand].
Toe transfer is a well established procedure for thumb and finger reconstruction after mutilation. The indications in congenital malformations are a mater of controversy. Out of a personal series of 209 patients, 42 were children presenting a congenital malformation. Thirty six, with 46 transfers were available for review. There is only one failure at the beginning of our experience. The main indication was absence of pinch either due to absence of thumb (like in congenital band syndrome or some extreme cases of ulnar club hand or cleft hand) or absence of long finger (like in symbrachydactyly monodactylous type) or lack of both thumb and finger (like in peromelic type of symbrachydactyly). In this last type, we have been disappointed by the functional result of the distal implantation of two second toes taken from both feet; we have proposed a "stub" operation consisting in a second toe transfer on the anterior aspect of the radial epiphysis to take advantage of the mobility of the wrist and the availability of plenty tendon transfer (in this proximal situation). When planing to "built" an absent pincer, an early age is mandatory for operation (mean 12 months), to ensure a good cortical integration. A less frequent indication is a partial toe transfer with a vascularized epiphysis to provide growth and mobility in some cases of thumb hypoplasia (like in symbrachydactyly or Blauth and Manske type III b). Results are difficult to assess due to the early operation but if the mobility has been disappointing (mean 32 degrees), sensibility (mean 2PD 5 mm) and growth were excellent.
