Abstract

Avascular necrosis (AVN) of the first metatarsal head following the chevron procedure for hallux valgus correction, has been reported widely in the literature; however, in practice it is rarely encountered and may be an over reported myth associated with the chevron technique. Although an infrequent complication, the consequences for those who develop post-operative AVN can be severe. This paper presents an overview of the pathogenesis and classification of AVN. It reviews the vascular anatomy of the first metatarsal with reference to the surgical technique of chevron osteotomy with lateral release. Imaging techniques are described and the management of AVN and revision surgery are also discussed.
