Clinical Example: Amputation revision, digital nerves implanted into bone

This patient had a thumb tip avulsive amputation treated elsewhere with a V-Y advancement flap. There was inadequate soft tissue cover, terminal digital neuromas, poor vascularity of the tip, constant aching pain and persistent tenderness. Out of the variety of treatment options, including another try to add more skin to the tip with a flap, the patient chose amputation revision.
