A modified subtalar arthrorisis is obtained by implantation of an endoprosthesis manufactured from ultrahigh molecular weight polyethylene. It is fashioned into the shape of a peg and implanted into the dorsal surface of the calcaneus just anterior to the posterior facet of the subtalar joint and fixed with polymethylmethacrylate. The purpose of the implant is to eliminate abnormal pronation, correct heel valgus, and produce an increase of the medial longitudinal arch in the growing child.
通过植入由超高分子量聚乙烯制成的假体来实现改良距下关节固定术。该假体被制作成栓子形状,植入距下关节后关节面正前方的跟骨背侧表面,并用聚甲基丙烯酸甲酯固定。该植入物的目的是消除异常内旋,纠正足跟外翻,并使正在生长的儿童的内侧纵弓增加。
