Abstract
We evaluated the results of 33 feet in 23 patients who underwent a basilar crescentic osteotomy with a modified McBride procedure with a minimum 24-month follow-up. The average hallux valgus improved from 37.5° to 13.8° and the intermetatarsal 1–2 angle from 14.9° to 4.7°. The angle of declination of the first metatarsal was found to have dorsiflexed an average of 6.2°. Unfortunately, osteotomies secured with staples dorsiflexed to a greater degree. Bilateral foot surgery produced results similar to those with unilateral procedures. Four of our patients developed a hallux varus (range 2–8°); however, none were dissatisfied at the time of evaluation. Although this bunion procedure resulted in more prolonged swelling and pain than a distal osteotomy, it should be considered for more complex deformities to avoid the failure that a distal metatarsal osteotomy might produce given a high 1–2 intermetatarsal angle or a high hallux valgus angle.
