[An analysis of the anatomical changes of the RA forefoot and the biomechanical consequences after the resection of the metatarsal heads (authors transl)].

Deformities of the forefoot depend on various mechanical factors as well as on the anatomical structure of the foot and the sufficiency of its individual static-dynamics elements. RA affects primarily the small joints and at the some time accelerates the deformative process of the forefoot. Reviewing literature and using his own observations as a basis the author discusses various causes of deformities and conducts an analysis of the biomechanical consequences after the resection of the metatarsal heads.
