Cross-leg flaps: Case series, review, and proposed classification

Area of Science:

• Reconstructive Surgery
• Plastic Surgery
• Microsurgery

Background:

• Cross-leg (CL) flap procedures have been utilized in reconstructive surgery since 1854.
• These flaps are valuable for addressing various reconstructive challenges, often yielding positive results.

Purpose of the Study:

• To propose a novel classification system for cross-leg flaps based on their blood supply and modifications.
• To evaluate the efficacy of posterior tibial artery perforator CL flaps and superiorly based sural CL flaps in patient management.

Main Methods:

• A retrospective analysis of 10 patients undergoing CL flap procedures.
• Utilization of posterior tibial artery (PTA) perforator CL flap and superiorly based sural CL flap techniques.
• Donor site reconstruction using skin grafts.

Main Results:

• All flaps achieved successful survival and smooth healing, providing stable coverage.
• Skin grafting for donor sites resulted in satisfactory outcomes for patients.
• The study demonstrates the effectiveness of the utilized CL flap techniques.

Conclusions:

• This study introduces a new, simple classification system for CL flaps, consolidating various described types.
• Cross-leg flaps are a reliable reconstructive option for patients with mobility impairments due to injury.
