Modified Wilson Technique for Treatment of Hallux Valgus

Abstract

Background: Moderate to severe hallux valgus deformity demands correction of the deformity. The purpose of the current study was to evaluate the results and advantages of the modified Wil-son technique for treatment of hallux valgus. Twenty four operations of distal oblique osteotomies on the first metatarsal bone as described by Wilson (1963) with some modifications were per-formed on fifteen patients suffering from hallux valgus, done in the Department of Orthopedic Surgery and Traumatology of El-Minia University Hospital; nine of them were bilateral and six were unilateral. The osteotomy site was fixed by K. wire after displacement of the distal fragment laterally and proximally. A below the knee plaster cast was applied and the patients were encour-aged to bear weight partially after the second post-operative week. The K. wire was removed after 6 weeks and the cast was removed after 10 weeks. Excellent results occurred in 18 out of 24 feet operated (75%), good in 3 feet (12.5%), fair in 2 feet (8.33%) and poor in one case (4.17%). Con-clusions: These modifications added more advantages to Wilson technique as a good procedure for treatment of hallux valgus.
