Loss of dorsiflexion is a common problem in cases where an external fixator or Ilizarov assembly is applied. It results in functional impairment of the foot by affecting the swing phase of gait cycle. We devised a simple dynamic dorsiflexion assist splint for prevention, correction of equinus/cavus deformity and maintenance of normal dorsiflexion of foot.
This prospective study used a rubber splint styled in the shape of a catapult, made of discarded car rubber tubes attached to the frame of fixator in 50 patients.
In 17 patients there was varying amount of loss of dorsiflexion at the time of application of splint while in 22 patients it was applied soon after the application of the fixator. In the rest of patients it was applied for cavus deformity. Out of 17 patients 10 had complete recovery of dorsiflexion. 22 patients in whom it was applied at the outset had normal range of movement at ankle. Correction was achieved in all 6 cases of cavus deformity and prevented its occurrence in the rest of 5 cases.
Catapult splint is a low cost foot dorsiflexion assist splint.
当使用外固定器或伊利扎洛夫组件时，背屈丧失是一个常见的问题。它通过影响步态周期的摆动阶段来影响脚的功能。我们设计了一种简单的动态背屈辅助夹板，用于预防、矫正马蹄内翻/外翻畸形和维持脚的正常背屈。
本前瞻性研究使用了一种形状像弹弓的橡胶夹板，由废弃的汽车橡胶管制成，固定器框架上附有这种橡胶管。
在 50 名患者中，有 17 名患者在应用夹板时有不同程度的背屈丧失，有 22 名患者在应用固定器后不久就应用了夹板。其余患者则是为了矫正马蹄内翻足畸形而应用夹板的。在 17 名患者中，有 10 名患者完全恢复了背屈。在一开始就应用夹板的 22 名患者中，踝关节活动范围正常。6 例马蹄内翻足畸形均得到矫正，其余 5 例也预防了畸形的发生。
弹弓夹板是一种低成本的足部背屈辅助夹板。
