Fig. 1

Geometrical model of hallux valgus in the anterior-posterior plane. The model is based on four radiographic parameters: α the preoperative intermetatarsal angle (first and second metatarsal) [degrees], W subcapital width of the first metatarsal [millimeters], E eminence-bunion protrusion from the metatarsal bone shaft [millimeters], L length of the first metatarsal from its base to the head center [millimeters]
