La double ostéotomie métatarsienne et phalangienne du premier rayon dans le traitement de l’hallux valgus

Numerous surgical techniques have been proposed for the surgical treatment of hallux valgus. Some of them only concern soft tissues; others combine a surgery on the soft tissues with a procedure on the bone structures. The technique we present combines a basimetatarsal valgization by subtractive external osteotomy with a wide metatarsophalangeal freeing. The basimetatarsal osteotomy allows correcting the deformities in the three planes of space. The basiphalangeal osteotomy is not systematic but is proposed in case of severe hallux valgus, superior to 45° or in case of hallomegalia (gigantism of hallux).
