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 degrees.
改良梅奥手术可矫正第一跖趾关节骨关节炎继发的拇趾外翻畸形。可同时进行第一跖骨基底截骨术以矫正第一跖骨内翻并维持拇外翻畸形的矫正。我们回顾性分析了采用该联合手术治疗的70只足中55只足的结果。平均随访时间为4.2年（范围0.5 - 6年），平均手术年龄为63岁（范围45 - 80岁）。结果非常好或好的占82%，中等的占14%，差的占4%。我们的第一跖骨基底截骨技术是一种矫正第一跖骨内翻的简单有效方法，可恢复远端横弓。当跖间角大于10度时，应将其视为一种可能的治疗方法。
