Abstract：
UNASSIGNED: 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.
METHODS: 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.
UNASSIGNED: 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.
CONCLUSIONS: 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.

摘要：
■数字神经撕裂在理性上很常见，尤其是在穿透性损伤之后。大多数患者以麻木为主要主诉。然而,电击疼痛是部分神经损伤的罕见表现。
方法：一名65岁女性，因三周前在近端指骨的掌侧有1厘米的裂伤，导致部分指神经损伤和电击征。手术探索发现数字神经中有神经瘤样肿块；然而，神经的连续性非常完整。
■由于数字神经的肤浅，穿透性神经损伤在这个领域是合理的常见。指神经裂伤会导致感觉丧失,笨拙，甚至丧失功能。渐渐地,神经瘤的形成会给上述症状增加局部疼痛和电击症状。
结论：电击征是指状神经部分损伤的特征，机制不明。症状似乎是进行性的，并且随着神经瘤的形成而更加复杂。
