Summary

The parametacarpal ulnar flap, a versatile surgical technique, effectively reconstructs hand and finger defects. Its dual vascular supply allows for direct or reverse flow applications in plastic and reconstructive surgery.

Area of Science:

  • Plastic Surgery
  • Hand Surgery
  • Anatomy

Context:

  • Reconstruction of skin loss in the palm and fingers is a common challenge in hand surgery.
  • The parametacarpal ulnar flap offers a potential solution for such defects.

Purpose:

  • To describe the anatomy and surgical technique of the parametacarpal ulnar flap.
  • To evaluate the flap's utility in ten clinical cases of hand reconstruction.

Summary:

  • The parametacarpal ulnar flap is supplied by the distal dorsal branch of the ulnar artery and innervated by the dorsal sensory branch of the ulnar nerve.
  • It can be raised for direct flow to reconstruct palmar defects or reverse flow for defects on the fourth and fifth fingers.
  • Anastomosis with the fifth ulnar collateral artery is a key feature enabling its dual-flow capability.

Impact:

  • Provides a detailed anatomic understanding for precise flap elevation.
  • Demonstrates the flap's versatility and effectiveness in diverse hand reconstruction scenarios.
  • Offers valuable insights into the indications for this flap in clinical practice.
