Contributor: Jared Scott, MD

Educational Pearls:

  • Traditional digital block involves dorsal approach on either side of the digit, injecting local anesthetic along each side to numb all four nerves of the digit
  • Newer approach involves a single injection along the palmar surface at MCP joint
  • Recent study further compared a proximal vs distal single palmar (volar) injection with sites at the MCP and PIP joints
  • Injection sites achieved similar anesthesia between groups but PIP injection site had faster time of onset - 2.5 minutes compared to 3.8 minutes
