Reconstructive Microsurgery

Background:

Lower extremity reconstruction presents significant challenges due to exposed bone, limited local tissue, and frequent vascular insufficiency.
Traditional free flap reconstructions for distal lower limb defects were often complex and carried risks, especially in patients with comorbidities.

Purpose of the Study:

To evaluate the efficacy of perforator-pedicled propeller flaps for lower extremity reconstruction.
To highlight propeller flaps as a viable alternative to free flaps, offering local tissue restoration without major vessel sacrifice or microanastomosis.

Main Methods:

Utilized perforator-pedicled propeller flaps for reconstruction of lower extremity defects.
Leveraged reliable perforators from the leg's three main source vessels for flap coverage.
Assessed flap suitability for small- to medium-sized defects with consideration of donor-site morbidity.

Main Results:

Perforator-pedicled propeller flaps provide effective like-with-like reconstruction for the lower extremity.
These flaps avoid compromising main limb vessels and underlying muscles, eliminating the need for microanastomosis.
Minimal donor-site morbidity is observed, making them suitable for various defect etiologies.

Conclusions:

Perforator-pedicled propeller flaps are an advantageous reconstructive option for lower extremity defects, especially in the distal leg and foot.
They offer a safe and effective alternative to free flaps, particularly for patients with comorbidities.
Advanced age, diabetes mellitus, and atherosclerotic peripheral vascular disease are relative contraindications.
