ResumoThe modified Wilson osteotomy for hallux valgus is a double oblique osteotomy through the meta-tarsal shaft. The distal fragment is displaced laterally and plantarward. The lateral displacement corrects the varus position of the met atar sal, while the plantar displacement prevents the distal fragment from tilting dorsally into a metatarsus elevatus deformity that could produce metatarsal-gia. Seventy-four cases of hallux valgus treated by this method were reviewed five years postopera-tively. Sixty-six cases (89%) were graded as satisfactory and eight (11%) as unsatisfactory. Roent-genographic analysis in 61 cases showed the operation had reduced the hallux valgus angle by an average of 15° and the intermetatarsal angle by an average of 4°. The operation shortened the first metatarsal by an average of 5 mm. Although this caused callosities on the forefoot, it did not produce metatarsalgia. The operation is technically uncomplicated and yields a high percentage of satisfactory results.
