Injury of digital nerve

Last edited: 4/15/2026

Overview

Digital nerve injuries of the hand are traumatic injuries that can occur both to surgeons during surgical procedures and to patients, often resulting from penetrating trauma 1. These injuries can lead to significant functional impairment and require careful management to prevent complications such as infection 1.

Diagnosis

  • Clinical Presentation: Tingling, numbness, pain, and motor deficits in the affected digit 1.
  • Physical Examination: Assess sensory and motor function, including Tinel's sign and nerve palpation 1.
  • Electromyography (EMG) and Nerve Conduction Studies: Useful for grading severity and monitoring recovery 1.
  • Imaging: Not typically required unless to rule out fractures or other structural injuries 1.

    • Management

  • Surgical Repair: Primary repair within 72 hours for optimal outcomes 1.
  • Antibiotics: Prophylactic use to prevent infection, especially in penetrating injuries 1.
  • Wound Care: Proper dressing and monitoring for signs of infection 1.
  • Splinting: Immobilization to protect the nerve during healing 1.
  • Physical Therapy: Gradual rehabilitation to restore function post-repair 1.

    • Special Populations

  • Surgeons: High incidence of penetrating injuries during surgical procedures; emphasize infection prevention 1.

    • Key Recommendations

  • Prompt surgical repair of digital nerve injuries within 72 hours to optimize functional recovery (Evidence: Moderate 1).
  • Implement prophylactic antibiotics in cases of penetrating injuries to reduce infection risk (Evidence: Moderate 1).
  • Regular monitoring with EMG and physical examinations is crucial for assessing recovery and guiding rehabilitation (Evidence: Moderate 1).
