Summary
This study redefines the gracilis musculocutaneous flap design by detailing its vascular anatomy. A new transverse flap design ensures consistent inclusion of skin perforators for improved reconstructive surgery outcomes.
Area of Science:
- Anatomy
- Vascular Surgery
- Reconstructive Surgery
Background:
- The gracilis musculocutaneous flap is a common reconstructive tool.
- Understanding its precise vascular supply is crucial for flap design and success.
Observation:
- Latex injection and anatomical dissection of 24 cadaver legs were performed.
- The proximal gracilis pedicle was consistently located 10 +/- 2 cm below the pubic tubercle.
- Both septocutaneous and musculocutaneous perforators were identified originating from the proximal pedicle.
Findings:
- Perforator vessels exhibited a significant transverse orientation.
- These perforators supplied skin areas over the adductor longus and sartorius muscles.
- The vascular territory extended over 5 cm posterior to the gracilis muscle margin.
Implications:
- A novel transverse gracilis musculocutaneous flap design is proposed.
- This design ensures reliable inclusion of vascular perforators within the flap.
- Improved flap viability and reconstructive outcomes are anticipated compared to traditional designs.
