Summary
This study introduces a novel distally based medial gastrocnemius flap for leg reconstruction. Anatomical analysis reveals variable distal pedicle size, impacting flap viability for reconstructive surgery.
Area of Science:
- Plastic surgery
- Microsurgery
- Anatomy
Background:
- Reconstructive surgery often requires versatile flaps for complex tissue defects.
- The medial head of the gastrocnemius muscle is a potential source for reconstructive flaps.
- Previous techniques using the medial gastrocnemius primarily focused on proximal pedicles.
Observation:
- A distally based flap utilizing the medial head of the gastrocnemius, vascularized by a distal pedicle from the posterior tibial artery, is described.
- A literature review indicated this specific distal pedicle flap had not been previously documented.
- Surgical techniques for distal third leg coverage using the medial gastrocnemius exist but differ in vascular supply.
Findings:
- The distal pedicle's caliber is variable, influencing the feasibility of raising the flap.
- Anatomical study of 30 legs showed 9 with pedicles >1 mm, 14 with pedicles <1 mm, and 7 with microscopic pedicles unsuitable for flap elevation.
- One patient successfully underwent reconstruction using this distally based flap technique.
Implications:
- This flap offers a potential new option for reconstructing distal leg defects.
- The variability in distal pedicle size necessitates careful preoperative assessment.
- Further research is warranted to refine patient selection and surgical technique for this flap.
