Digital Nerves

Description

Cross section of a finger showing the digital nerves

• Each digit is innervated by four digital nerves, 2 Dorsal (10 and 2 o'clock positions) and 2 Ventral (4 and 8 o'clock positions)
• Run along medial and lateral digits as branches:
  • Hand: median nerve, ulnar nerve
  • Foot: tibial nerve, common peroneal nerve
• All 4 nerves need to be blocked to achieve anesthesia
• Digital vessels run adjacent to the arteries
• Palmer nerve: innervates all of the finger, nail bed except for the dorsum of the finger
• Dorsal nerve: dorsal digit (except nail bed)
