Acquired hallux varus and clinical tolerability.

Abstract

This retrospective study was undertaken to determine the long-term clinical problems, residual disability, and need for further surgery in patients with iatrogenic hallux varus. Between 1975 and 1985, in 16 (19 feet) of 83 patients who underwent foot surgery for hallux valgus or metatarsus primus varus, hallux varus deformity was noted at 1-year follow-up on dorsoplantar roentgenograms obtained with the patients bearing weight. Thirteen of those patients (16 feet) were reexamined at an average of 18.3 years (220 months) after surgery. The average hallux varus deformity in this group was 10.1 degrees. Eleven patients (12 feet) rated their results as excellent. The average hallux metatarsophalangeal interphalangeal score for all patients was 91.5 points. Only those with extreme hallux varus deformity were dissatisfied or required further surgery.
