Plantar pressure distribution in hallux valgus feet after a first metatarsal proximal crescentic osteotomy with a lesser metatarsal proximal shortening osteotomy

Plantar pressure distribution after the first metatarsal proximal crescentic osteotomy (FMPCO) with lesser shortening (LMPSO) for hallux valgus metatarsalgia has not been previously described. The pre- (Pre) and postoperative (Post) groups comprised of 18 patients who underwent unilateral FMPCO LMPSO; fifteen healthy volunteers constituted control (C) group. For each 10 regions, peak (Peak-P), maximum force (Max-F), contact time (Con-T), area (Con-A), force-time integral (FTI) were measured. mean Peak-P second head was significantly lower in Post group than Pre Peak-P, Max-F, Con-T, FTI different between C groups. Con-A LMPSO may improve plantar central forefoot comparable to subjects.
