One case of disability grade assessment for partial amputation of one foot caused by accidental injury
意外伤致一侧足部分截肢残疾等级评定1例

摘要

本文报告一例因意外伤害导致右足部分截肢的残疾等级评定案例。受害人李某因货梯坠落致右足不全离断，经治疗后遗留右足自第1-5跖骨基底部以远缺失。鉴定过程中，依据《人体损伤致残程度分级》标准，采用附录中足缺失评分示意图进行功能量化评估，其右足功能丧失分值为75分。根据残疾七级条款，手或足功能丧失分值≥60分，最终评定为七级残疾。结合该案例，对足部解剖结构、伤残评定标准中具体条款与量化评分条款的适用关系进行了探讨，指出在损伤无法对应具体定级条款时，量化评估具有重要价值，同时建议未来标准修订时对量化评估方式进一步细化。

Abstract

This case report presents the disability rating assessment of a patient who sustained partial right foot amputation due to accidental injury. The claimant, Mr. Li, suffered an incomplete amputation of the right foot following a fall into a freight elevator. After clinical management, he was left with a residual limb ending distal to the bases of the first through fifth metatarsal bones. During forensic evaluation, the “Classification of Disability Levels Caused by Personal Injury” was applied; specifically, functional impairment was quantified using the foot-loss scoring diagram provided in the standard 's appendix, yielding a functional loss score of 75 points for the right foot. As stipulated under Grade VII disability criteria-“functional loss score ≥60 points for hand or foot”-the patient was formally rated as having a Grade VII disability. Drawing on this case, we discuss the anatomical features of the foot and examine the interpretive relationship between specific grading clauses and quantitative scoring provisions in the disability evaluation standard. We highlight that quantitative functional assessment serves a critical role when injuries do not map directly onto explicit grading clauses, and we recommend that future revisions of the standard further refine and standardize such quantitative methodologies.
