GRICE SUBTALAR ARTHRODESIS - A LONG-TERM FOLLOW-UP IN POLIOMYELITIS

A retrospective review was done of 19 poliomyelitis feet on which the standard Grice subtalar arthrodesis was performed for correction of valgus feet deformity. The average time of follow-up was 12,1 years. Seventy-nine per cent of the feet had satisfactory results, and all the failures were due to technical errors of graft placement. The calcaneo-first-metatarsal angle on the standing lateral radiograph was found to be the most objective angle and correlated best with the clinical results. The long term effects on the rest of the foot was negligible, with only 3 of the 10 feet, with a follow-up longer than 12 years showing minimal talonavicular arthritis and only 1 ankle developing a ball and socket joint. Ankle valgus was not a significant problem.
