[Congenital quintus varus supraductus: surgical procedure].

Quintus varus supraductus is a congenital malformation that associates a hyperextension, a varus and an external rotation of the fifth toe coming over the fourth. The goal of this study is to explain an easy, reproducible and efficient surgical procedure to correct that malformation. Our procedure is only about soft tissues. It comprises a fifth toe extensor tenolysis, a circular capsulotomy and lateral ligament section of the fifth metacarpophalangeal articulation. The glenoid plaque is desinserted only if the peroperative reduction did not seem sufficient. The stabilization is achieved through a cutaneous plasty of modified BUTLER, with a cutaneous lengthening VY plasty. Exceptionally, an axial broaching of the articulation has been done. On about 20 children, aged 4-17 years, operated with this procedure, we have noticed a complete and definitive correction in 19 patients. Only one patient showed an incomplete resurgence, but without any functional disturbance. We did not notice any failure. This procedure seems efficient, and all the more interesting that it is technically easy to perform.
