Role of Coronal Plane Malalignment in Hallux Valgus Correction

Coronal malalignment is an important deformity parameter in hallux valgus feet. Approximately 90% of patients with hallux valgus have some degree of metatarsal pronation. In operated hallux valgus, persistent metatarsal pronation is an independent deformity relapse factor. Coronal malalignment can be identified through an anteroposterior (AP) weight-bearing foot radiograph and a weight-bearing forefoot scan. The AP foot view can identify 3 levels of rotation: mild, moderate and severe metatarsal pronation. Regarding the treatment options, some techniques are capable of rotational correction, such as the proximal rotational metatarsal osteotomy, Lapidus, dome osteotomy, and proximal oblique sliding closing wedge.
