Abbiihl, E. Morscher, J. Wilson-MacDonald] Summary: The modified Mayo procedure corrects valgus deformity of the great toe secondary to osteoarthritis in the first metatarsophalangeal joint. Basal osteotomy of the first metatarsal to correct metatarsus primus varus and to maintain correction of the valgus deformity may be performed simultaneously. We retrospectively reviewed the results in 55 of 70 feet treated by this combined procedure. The average duration of follow-up was 4.2 years (range 0.5-6 years) and the average age at operation was 63 years (range 45-80 years). The results were either very good or good in 82%, moderate in 14%, and poor in 4%. Our technique of basal osteotomy of the first metatarsal is a simple and effective procedure to correct metatarsus primus varus and may restore the distal transverse arch. It should be considered as a possible method of treatment when the intermetatarsal angle is greater than 10°. Springer-Verlag, 1992 Abbiihl U.
