RESUMO
The first metatarsophalangeal joint arthrodesis is a fusion with optimal alignment of the first metatarsal and first phalanx which conferring indolence, strength and stability. The goal of this study was to evaluate the place of arthrodesis of the first metatarso-phalangeal joint in surgery of the fore foot. This work is based on analysis of records of 35 patients between 1995 and 2006. 39 first metatarsophalangeal joint arthrodesis were practice [3 were bilateral]. They had a follow up of from three to ten years. All patients were called for a complete exploration radiographic and clinical evaluation according to the criteria of KITAOKA. The average age of patients was 54 years. They were 28 women and 7 men. The indications were hallux rigidus in 51% cases and rheumatoid arthritis in 41% cases. The procedures used mostly a stable fixation with a compressive screw. The dorsal flexion recommended is between 20 and 30 [degree sign]. Ankylosis of the ankle or the inter-phalangeal joint was an against-indication for the first metatarsophalangeal joint arthrodesis. The study found a patient subjective satisfaction rate of 92 percent, there was no pain for 89 per cent of cases. It was noted 4 non-fusion cases paradoxically with satisfactory functional result. There was no pain of inter-phalangeal joint in all cases when X-rays showed arthritis in 4 cases. The first metatarsophalangeal joint arthrodesis, provided we respect a few simple principles, restores painless and satisfying function of foot
