Adult hallux valgus with metatarsus adductus: a case report.

It is difficult to surgically treat a hallux valgus deformity with significant metatarsus adductus, because the space between the first and second metatarsals is too narrow to correct the metatarsus primus varus with a first metatarsal osteotomy. A 55-year-old woman had severe hallux valgus with significant adduction of the second and third metatarsals. A distal soft tissue procedure and a proximal crescent-shaped osteotomy of the first metatarsal combined with corrective osteotomies of the second and third metatarsals were done. The patient's symptoms disappeared, and hallux valgus and adduction of the second and third metatarsals were corrected. To the authors' knowledge, there is no previous description of surgical treatment including correction of metatarsus adductus and hallux valgus for adult hallux valgus with metatarsus adductus.
