The history and prosthetic difficulties of a patient with an unusual Chopart amputation variant have been presented. Although it is possible for the Chopart amputee to walk with just a shoe and filler, this patient does best with a formal prosthesis. The Chopart amputation, which has been surgically stabilized with Achilles tendon lengthening to prevent equinus contractures, can be fitted successfully with a lightweight circumferential plastic or silicone prosthesis or more traditionally with a solid ankle foot orthosis with filler. This partial foot prosthesis is worn with a sturdy shoe with a rocker and solid ankle cushion heel or a well constructed running shoe. The Chopart amputee with equinus contractures must be fitted with a Chopart clamshell prosthesis or solid ankle patellar tendon bearing orthosis with filler and the above shoe prescription. Recent variants of the partial foot prosthesis including the Imler partial foot prosthesis, the Lange silicone prosthesis, and the ankle corset prosthesis were described.
本文介绍了一名具有特殊Chopart截肢变异患者的病史及假肢适配困难情况。虽然Chopart截肢者仅靠一只鞋和填充物也有可能行走，但该患者使用正式假肢效果最佳。通过跟腱延长术进行手术稳定以防止马蹄足挛缩的Chopart截肢，可成功适配轻质环形塑料或硅胶假肢，或者更传统地适配带有填充物的坚固踝足矫形器。这种部分足假肢需搭配带有摇杆和坚固踝垫后跟的结实鞋子或精心制作的跑鞋使用。患有马蹄足挛缩的Chopart截肢者必须适配Chopart蛤壳式假肢或带有填充物及上述鞋类处方的坚固踝髌腱承重矫形器。文中还描述了部分足假肢的最新变体，包括Imler部分足假肢、Lange硅胶假肢和踝部紧身胸衣式假肢。
