Three-dimensional Reconstruction of Magnetic Resonance Images of a Displaced Flexor Hallucis Longus Tendon in Hallux Valgus

Abstract

By using three-dimensional magnetic resonance image reconstruction, lateral displacement of the flexor hallucis longus tendon and sesamoid bones was made clearly visible in a living patient. This finding supports a biomechanical model related to disturbed muscle balance at the first metatarsophalangeal joint, which could play an important role in the pathogenesis of hallux valgus and metatarsus primus varus.
