Ilizarov reconstruction of chronic bilateral calcaneovalgus deformities / 中华创伤杂志(英文版)

ABSTRACT

Calcaneovalgus foot deformities are present in up to 35% of patients with lumbar spina bifida. Resultant heel weight bearing causes complications include those associated with pressure ulcers. Early surgical reconstruction is advocated to prevent deformity progression and rigidity. Several surgical techniques in paediatric populations have been described, but there remains a paucity of literature regarding reconstruction of chronic calcaneovalgus feet in adults. This case report describes our experience using the Ilizarov technique in the reconstruction of an adult presenting with chronic calcaneovalgus feet. This is a 34-year-old lady with myelomeningocoele spina bifida of lumbar level 5 who presented with a history of multiple admissions for cellulitis and infections of bilateral heel pressure sores. Rigid calcaneovalgus deformities of both feet (45° on the right, 40° on the left) were noted on clinical examination and radiological investigations. Reconstruction with an Ilizarov frame allowed for gradual correction of both soft tissue and bone, correcting heel weight bearing ambulation, with the aim of preventing further complications from infected heel ulcers. While the correction of bony deformities is crucial, management of chronically contracted soft tissue must not be overlooked. An Ilizarov frame requires both an experienced surgeon and a motivated patient, but it allows for accurate reconstruction of bony deformities, while allowing management of surrounding chronic soft tissue contractures with good functional outcome.
