Hallux valgus and metatarsus primus varus treated by bunionectomy and proximal metatarsal osteotomy.

Sixteen feet with hallux valgus and metatarsus primus varus have been treated by excision of the exostosis of the first metatarsal head, advancement of the medial capsule and the abductor hallucis, release of the lateral capsule and adductor tendon, and open-wedge osteotomy at the base of the first metatarsal inserting a bone graft. During a three-year period ther have been no nonunions of the osteotomy, and satisfactory maintenance of the corrections has occurred. This method is preferred over distal metatarsal osteotomy.
