Transfer metatarsalgia post hallux valgus surgery.

Abstract

Metatarsalgia, pain around the metatarsophalangeal joints, may arise from mechanical causes spontaneously or iatrogenically. Nonunion or malunion of the first metatarsal can transfer weight-bearing forces and overload the lesser metatarsals. Transfer metatarsalgia after failed hallux valgus surgery is troublesome and more prevalent than would be expected. Clinical examination of the patient allows identifying the type of transfer metatarsalgia and pathomechanics involved. This review focuses on transfer metatarsalgia after hallux valgus surgery and provides a basic understanding of the pathomechanics, clinical examination, and image studies. It also addresses the options for both conservative and surgical treatment of this challenging condition.
