Pied varus équin de l’adulte traité par arthrodèse tibiocalcanéenne: à propos de deux cas (3 pieds)

Inveterate clubfoot (inveterate talipes equinovarus, ITEV) is a vicious attitude of the foot which doesn’t rest on the floor through its normal base of support but weight is thrown to the outer side of the foot and to the foot point. When this vicious attitude persists a long time, it results in severe osteoarticular deformities in adults. Fixed ITEV is a good indication for tibiocalcaneal arthrodesis. In the majority of cases this provides painless and stable plantigrade foot. This study aims to assess the clinical and radiological outcomes of astragalectomy with tibiocalcaneal fusion. This case series involves 2 adult patients undergoing tibiocalcaneal arthrodesis due to severe and annoying equinovarus rearfoot deformity. Outcome was satisfactory with painless and stable plantigrade foot. At 90-day follow-up the patient with bilateral clubfoot had no inequality while the patient with unilateral clubfoot had a shortening of 2 cm compensated by right sole. In the majority of cases with severe and fixed deformities of the ankle and of the ITEV, tibiocalcaneal arthrodesis allows for painless and stable plantigrade foot, without vascular or cutaneous risk.
