Chevron osteotomy for hallux valgus.

The chevron osteotomy for realignment of the first metatarsal head in metatarsus primus varus deformity has been utilized at the Mayo Clinic since 1976 on 26 feet (18 patients). Follow-up evaluation disclosed excellent relief of pain, good cosmetic correction, and overall patient satisfaction. Radiographic evaluation demonstrated reduction in the angle between the phalanx and the metatarsal bone of the great toe as well as narrowing of the forefoot with a decreased angle between the first and the second metatarsal bones. The stability of the osteotomy, the technical ease, and the absence of secondary difficulties such as transfer metatarsalgia make this procedure preferable when osteotomy of the distal portion of the first metatarsal bone is used for correction of moderate deformity.
