INTRODUCTION AND IMPORTANCE
Digital nerve lacerations are rationally common, especially following penetrating injuries. The majority of patients suffer from numbness as the main complaint. However, electric shock pain is a rare manifestation of partial nerve injury.
CASE PRESENTATION
A 65-year-old woman with partial digital nerve injury and an electric shock sign due to a 1 cm laceration on the volar side of the proximal phalanx three weeks earlier. The surgical exploration revealed a neuroma-like mass in the digital nerve; however, the continuity of the nerve was grossly intact.
CLINICAL DISCUSSION
Due to the superficiality of digital nerves, penetrating nerve injuries are rationally common in this area. Laceration of the digital nerve could lead to loss of sensation, clumsiness, and even loss of function. Gradually, neuroma formation would add a local pain and electric shock sign to the mentioned symptoms.
CONCLUSION
Electric shock sign is characteristic for partial digital nerve injury with unknown mechanism. It seems the symptoms would be progressive and more complicated with neuroma formation.

引言与重要性
指神经撕裂伤较为常见，尤其是在穿透性损伤之后。大多数患者以麻木为主诉。然而，电击样疼痛是部分神经损伤的一种罕见表现。
病例介绍
一名65岁女性，三周前因近端指骨掌侧1厘米的撕裂伤导致部分指神经损伤并出现电击样体征。手术探查发现指神经中有一个神经瘤样肿块；然而，神经的连续性大体上是完整的。
临床讨论
由于指神经表浅，该区域穿透性神经损伤较为常见。指神经撕裂伤可导致感觉丧失、动作笨拙甚至功能丧失。逐渐地，神经瘤形成会使上述症状增加局部疼痛和电击样体征。
结论
电击样体征是机制不明的部分指神经损伤的特征。症状似乎会随着神经瘤形成而逐渐加重且更加复杂。
