Soft-tissue expander failure in severe equinovarus foot deformity.
Soft-tissue expanders have recently been reported to be useful in clubfoot surgery. We report our experience with this procedure in five patients with seven severe equinovarus foot deformities. The primary diagnoses of these patients included distal arthrogryposis, cerebro-oculo-facial syndrome, ischemic contracture and spina bifida. Our patients' major complications included ischemia, infection, and sepsis, which resulted in premature removal of the soft-tissue expanders in five of seven clubfeet. Minor complications, such as partial wound dehiscence, occurred in the two successful expansions. Predisposing factors may include soft-tissue expanders with self-contained ports, poor compliance, and extremely tight tissues that limit the subcutaneous space available for expansion, with resultant diminution of the vascular supply to the overlying skin.
