Metatarsophalangeal fusion for hallux valgus: indications and effect on the first metatarsal ray.

Arthrodesis of metatarsophalangeal joint was performed in 31 cases of severe hallux valgus. With the surgical technique used, which is described in detail, internal fixation and plaster cast immobilization were not necessary. Analysis of the results suggested that the operation is indicated for severe deformities in elderly patients, preferably women. The basic metatarsal deformity was corrected by the procedure.
