道路交通事故致足弓结构破坏伤残评定

足弓由横弓、内侧纵弓、外侧纵弓组成。足弓测量包括内弓角、外弓角、前弓角、后弓角和跟距角五个角度的测量。《道路交通事故受伤人员伤残评定》（GB18667—2002）标准将足弓结构破坏分为破坏1／3以上和完全破坏两种情形。前者是指足三弓（内侧纵弓、外侧纵弓、横弓）的任一弓结构破坏。后者是指一足三弓结构均有损害。当伤侧内弓角或外弓角测量值超过健侧10％时，提示内侧纵弓或外侧纵弓损坏；当伤侧前弓角或后弓角测量值小于健侧3％时，提示前弓或后弓破坏。在全面了解案情、严格审查送检材料，对被鉴定人进行体格检查和影像学检查后，可以做出最终判定。

The Disability Evalution on the Disorganization of Foot Arch in Traffic Accidents

Foot arch is constitute of transverse arch, medial longitudinal arch and lateral longitudinal arch. Foot arch measurement is composed of the angle of medial longitudinal arch, the angle of lateral longitudinal arch, the angle of anterior arch,the angle of posterior arch and Boehler＇s angle. As the national standard implemented in 2002, the ＂Assessment for Body Impairment of the Injured in Road Traffic Accident＂ difines the disorganization of foot arch as destruction over one third and completely destruction. The former means the destruction of one of the three angles. The later means the destruction of all three angles. It proves the destruction of medial longitudinal arch or lateral longitudinal arch when the angle of medial longitudinal arch or the angle of lateral longitudinal arch exceedes ten percet compared with the uninjured side. Also it proves the destruction of anterior arch or posterior arch when the angle of anterior arch or the angle of posterior arch exceedes three percent compared with the injured side. After getting the case detail and inspecting the materials submitted, the appraiser can reach the final assessment on the basis of physical examination and iconography examination.
