The posterior interosseous artery flap, a versatile option for reconstruction, can be used as a direct flow free flap. This refined technique enhances reliability for various defects, particularly when wrist or distal forearm injuries compromise traditional flap use.

Area of Science:

  • Plastic Surgery
  • Anatomy
  • Microsurgery

Background:

  • The posterior interosseous artery (PIA) is crucial for forearm vascularization.
  • The PIA flap is traditionally used as a reverse flow island flap.
  • Limitations exist with reverse flow flaps due to potential injury to distal forearm or wrist vasculature.

Observation:

  • The posterior interosseous artery forms important anastomoses proximally and distally with the anterior interosseous artery.
  • The flap can be reliably perfused via these anastomoses, enabling its use as a reverse flow island flap.
  • Limitations arise when distal forearm or wrist integrity is compromised.

Findings:

  • The study refined the posterior interosseous flap for use as a direct flow free flap, overcoming limitations of the reverse flow island technique.

  • Twenty-three free flaps were successfully used: 13 fasciocutaneous, 6 fasciocutaneous-fascial, and 4 fascial.
  • Thirteen sensory flaps utilized the posterior antebrachial cutaneous nerve, and all flaps successfully covered defects, primarily in the hand.

    • Implications:

    • The direct flow free posterior interosseous flap offers a reliable and versatile option for complex reconstructive challenges.
    • This technique expands reconstructive possibilities, especially for defects in the hand and other extremities.
    • Understanding the vascular anatomy and flap variations is critical for successful application in plastic and reconstructive surgery.
