Area of Science:

  • Plastic Surgery
  • Hand Surgery
  • Microsurgery

Background:

  • Reconstructive surgery for hand defects requires versatile flaps.
  • Existing dorsal hand flaps have limitations in certain defect types.

Observation:

  • A novel flap design was developed from dorsal hand skin.
  • The flap utilizes a pedicle-lengthening principle, transforming a "U"-shaped vascular structure to an "I"-shaped one.
  • Key vascular components include the second dorsal metacarpal artery and dorsal carpal arch.

Findings:

  • The dorsal metacarpal flap was successfully used in six cases for resurfacing defects.
  • Applications included large defects beyond the proximal interphalangeal joint and degloved fingers.
  • The flap demonstrated versatility as an innervated or tenocutaneous flap.

Implications:

  • This flap provides a valuable new option for complex hand reconstruction.
  • It expands the armamentarium for surgeons dealing with dorsal hand and finger injuries.
  • Further studies can explore its full potential in various reconstructive scenarios.
