title: Biomechanics of hallux valgus and spread foot.
abstract: In this biomechanical study a model is introduced of the force phenomena which seem to dominate in the hallux valgus complex during standing and push-off. The model was verified by measuring the forces under the big toe in three directions with the help of a force plate. It is shown that the force in the musculus flexor hallucis longus is accompanied by unfavorable side effects when the hallux shows a valgus position. On the basis of the biomechanics in this article, arthrodesis of the first metatarsophalangeal joint could be recommended as suitable treatment.
