The rectus abdominis free flap for lower extremity reconstruction

Area of Science:

• Plastic Surgery
• Microsurgery
• Reconstructive Surgery

Background:

• Traditional methods for lower extremity reconstruction include latissimus dorsi and gracilis muscle flaps.
• These methods may have limitations in certain reconstructive scenarios.

Observation:

• The rectus abdominis muscle flap presents a viable alternative for lower extremity reconstruction.
• This flap possesses a dual blood supply, enhancing its reliability.

Findings:

• The inferior epigastric vascular pedicle of the rectus abdominis flap offers a longer pedicle length and larger vessel diameter.
• These features are advantageous for free-tissue transfer in complex reconstructions.

Implications:

• The free rectus abdominis muscle flap expands reconstructive options for lower extremity defects.
• Understanding its surgical anatomy and technique is crucial for successful application.
