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.
近期有报道称软组织扩张器在马蹄内翻足手术中有用。我们报告了对5例患有7处严重马蹄内翻足畸形患者进行该手术的经验。这些患者的主要诊断包括远端关节挛缩症、脑眼面综合征、缺血性挛缩和脊柱裂。我们患者的主要并发症包括缺血、感染和脓毒症，这导致7例马蹄内翻足中有5例的软组织扩张器被提前取出。在两次成功扩张中出现了如部分伤口裂开等轻微并发症。诱发因素可能包括带有内置端口的软组织扩张器、依从性差以及极其紧绷的组织，这些组织限制了可供扩张的皮下空间，从而导致覆盖皮肤的血管供应减少。
