“Sandwich” osteotomy technique on 1st phalanx of the great toe in the surgical cure of the hallux valgus

Abstract

The sandwich operation in the surgical cure of the hallux valgus is an original technique. This evolution sprang from the limitations of the Petersen operation. It consists in a conservative arthroplasty of the 1st phalanx of the great toe combined with the Petersen technique. It allows three spatial modifications of the great toe deformity: a shortening, a rotation and a varisation.
