Hallux valgus and bunionette

Abstract

Hallux valgus is associated with multiple factors, such as genetic and anatomical abnormality and other disease entities such as rheumatoid arthritis, pes planus, generalized neuromuscular disease, etc. As for the hallux valgus with incongruent MTP joint, the surgical options according to the severity of the HVA and the IMA of the patient are classified. Although there are three approaches for the lateral soft tissue release, we prefer the single medial incision approach, because of avoidance of dorsal web operation scar, and the wide exposure. According to the severity of the hallux valgus especially by IMA, distal chevron osteotomy, scarf osteotomy, Ludloff osteotomy, proximal chevron osteotomy, and modified Lapidus procedure are the main surgical options that are commonly performed. Bunionette is classified into three types according to the morphologic structures and the surgical options such as lateral osteotomy and various osteotomies are performed.
