(see also: Blair Fusion; Charcot Marie Tooth ; Equinovalgus; Grice Arthrodesis; Kocher approach; Ollier incision; Subtalar Fusion) Discussion results in fusion of subtalar, calcaneocuboid, and talonavicular joints; most effective procedure for fixed hindfoot and forefoot deformities; triple arthrodesis tend to have a high (50%) failure rate in children under 10 years of age; triple arthrodesis … Read more
– See: Triple Arthrodesis: Discussion: – Discussion: – reserved for the most intractable problems and can only be done close to or at the time of skeletal maturity; – when osseous correction of the midfoot is needed, we prefer to maintain the talonavicular, calcaneocuboid, and talocalcaneal joints by using calcaneal and midfoot osteotomies supplemented with … Read more
– PreOp Planning: – knee deformities should be corrected prior to any forefoot fusions; – stability of talus in mortise is necessary for successful arthrodesis; – determine if flexibility of forefoot and hindfoot; – if foot can be reduced to a satisfactory position then an in situ type of arthrodesis may be considered; – if … Read more
