Effects of Wearing Foot Orthosis With Medial Arch Support on the Fifth Metatarsal Loading and Ankle Inversion Angle in Selected Basketball Tasks

Abstract

Generic use of off-the-shelf foot orthoses with medial arch support causes increased plantar forces and pressures on the fifth metatarsal and may increase the risk for proximal fracture of the fifth metatarsal. Future studies are needed to investigate this risk, acknowledging that the differences noted in our study were small in magnitude and the foot type was not measured.
