Marked hallux varus may be corrected by a tendon-loop operation around the first phalanx and the second metatarsal. The extensor hallucis longus tendon was utilized in the case described, but a free tendon graft from one of the other extensor tendons could also be used for the same purpose. Osteotomies of all the metatarsals are necessary if there is an associated metatarsus varus of the other toes.
