One of the complications of hallux valgus surgery is shortening of the first metatarsal and this becomes particularly symptomatic in patients with a pre existing short metatarsal (Morton's foot or Greek foot). Initial treatment consists of appropriate insoles which incorporate not only relief of pain due to pressure metatarsalgia under the lesser metatarsal heads but also a Morton type extension under the big toe. Insoles with metatarsal relief are, however, not always well tolerated and surgery becomes necessary. The options are to shorten the lesser metatarsal heads or lengthen the previously shortened first metatarsal. Arthrodesis of the great toe metatarso-phalangeal joint can provide functional length to the first metatarsal. We have achieved good results in lengthening of the first metatarsal and believe that it is a safe option which avoids trauma to the lesser metatarso-phalangeal joints. The technique is presented and depends on whether there is a residual hallux valgus or whether the toe is well aligned. The operation should address the plane of the deformity and reverse the cause of the lengthening. Emphasis should however be placed in not getting the complication in the first instance and the incidence of the problematic short first metatarsal has significantly reduced since the decrease in popularity of the Wilson osteotomy
