摘要： 目的比较Pilon 骨折患者手术后患侧及健侧动态足底压力的分布情况。方法31 例Pilon 骨折患者于术后1 年，采用平板式足底压力测试系统，测量患侧和健侧足底10 个区域峰值压力及冲量值。结果患侧第1 跖骨底(M1)、足跟外侧底(HL)、足跟内侧底(HM)峰值压力均低于健侧(P<0.05)，第4 跖骨底(M4)及第5 跖骨底(M5)峰值压力则高于健侧(P<0.05)。患侧M1、HL、HM冲量低于健侧(P<0.05)，患侧M5 及足中部底(MID)冲量高于健侧(P<0.05)。结论Pilon 骨折术后患者患侧足跟及前足内侧负重减
少，而前足外侧负重增加，前足外侧、足弓部易发生损伤。

Abstract: Objective To investigate the plantar pressure distribution of the injuried limbs and the healthy side after the operation for Pilon fracture. Methods 31 patients with Pilon fractures were tested with Footscan USB2 system, including the maximum force and impulse of 10 zones of the feet 1 year after surgery. Results Compared with the contralateral feet, the maximum force reduced under the the first metatarsal bone, medial heel, and lateral heel (P<0.05), and it increased under the fourth, and fifth metatarsal bone (P<0.05) of the injured feet. The impulse reduced under the the first metatarsal bone, medial heel, and lateral heel (P<0.05), and increased under the fifth metatarsal bone and midfoot (P<0.05). Conclusion The load decreased on the heel and medial forefoot, and increased on the lateral forefoot of the injured limbs after Pilon fracture, while the lateral forefoot and midfoot tend to be injured.
