Chevron osteotomy: analysis of factors in patients' dissatisfaction.

The results of all Chevron osteotomies for hallux valgus performed at the Mayo Clinic between January 1976 and June 1982 were reviewed at least 1 year after surgery. Of the total 157 patients with 228 operations eligible for inclusion in this study, 154 patients with 225 operations were interviewed. Complete satisfaction was expressed for 79.1% of the procedures, satisfaction with minor reservations for 12.9%, and dissatisfaction for 8%. For the osteotomies producing incomplete satisfaction, further investigation identified failure to achieve correction and technical errors as the most prominent factors. There were no cases of avascular necrosis, osteotomy nonunion, or hallux varus.
