O2564 LATER RESULTS OF MITCHELL CORRECTIVE METATARSAL OSTEOTOMY IN THE TREATMENT OF HALLUX VALGUS

Abstract

Aims: The aim of the study is to present later results in the treatment of hallux valgus with Mitchell corrective metatarsal osteotomy. Materials and methods: In the period from 1982 to 1991, 238 patients (230 females and 8 males) and 380 foots were operated. The patients were followed from 11 to 20 years. The age of the patients varied from 13 up to 55 years (the median value of around 36 years). Indications for the Mitchell corrective metatarsal osteotomy were, in the þrst place, the angel of hallux valgus bigger then 20 degrease, intermetatarsal angle bigger then 10 degrease, pain due to shoe pressure over the medial side of metatarsophalangeal joint, cosmetics appearance. In this study 130 patients with 230 foots were evaluated (radiological, clinical and subjective evaluation). Results: The angel of hallux valgus was 20 to 52 degrease (mean- 34,5 degres) before operation and was 8 to 36 (mean Ð 16,1 degrease) after operation. Intermetatarsal angle was 10 to 25 (median Ð 15 degrease) before operation and was 7 to 22 degrease (mean Ð 8 degrease) after operation. Shortening of þrst metatarsal bone was 2 to 6 mm (mean Ð 3 mm)Conclusion: The study shows that Mitchell corrective metatarsal osteotomy in treatment of hallux valgus is method of selection in younger patients and with distinctive intermetatarsal angle.
