The hallux valgus is one of the most challenging foot and ankle deformities to correct. The current concept is to consider the hallux valgus as a triplane deformity, and the parameters in transverse, sagittal, and frontal planes must be considered. The hallux valgus angle, intermetatarsal angle, tibial sesamoid position, and lateral edge of the first metatarsal head are valuable parameters to evaluate to understand the magnitude of the deformity. Diaphyseal corrections, such as scarf, and proximal interventions, such as crescentic osteotomy and Lapidus arthrodesis, are the most powerful techniques to address triplane deformity, because they are able to correct all misalignments.
拇外翻是最难矫正的足踝畸形之一。当前的观念是将拇外翻视为三平面畸形，必须考虑横切面、矢状面和额状面的参数。拇外翻角、跖间角、胫侧籽骨位置和第一跖骨头外侧缘是评估畸形程度的重要参数。骨干矫正术（如Scarf截骨术）和近端干预术（如新月形截骨术和Lapidus关节融合术）是解决三平面畸形最有效的技术，因为它们能够矫正所有的排列不齐。
