Lower extremity reconstruction with the anterolateral thigh flap

Area of Science:

• Plastic Surgery
• Orthopedic Surgery
• Reconstructive Surgery

Background:

• The anterolateral thigh (ALT) flap is recognized for its versatility and suitable location for lower extremity reconstruction.
• Defining its specific role across different anatomical regions is crucial for optimizing its application.

Purpose of the Study:

• To evaluate the surgical and functional outcomes of ALT flap reconstructions in specific lower extremity anatomical regions.
• To delineate the efficacy of the ALT flap based on defect location.

Main Methods:

• Retrospective review of 46 patients undergoing lower extremity reconstruction using ALT flaps (pedicled or free) between July 2002 and December 2010.
• Analysis of defect locations including hip/buttocks, groin, thigh, knee, leg, and foot/ankle.
• Assessment of surgical outcomes, flap survival, and functional recovery.

Main Results:

• Overall flap loss rate was 4% (2/46 patients).
• Recipient site complications occurred in 24% (11/46), with seroma being the most common (11%).
• 83% (38/46) of patients returned to their preoperative functional status.

Conclusions:

• The ALT flap is a highly effective option for lower extremity reconstruction, applicable as both pedicled and free flaps.
• Good surgical and functional outcomes support its use across diverse lower extremity defects.
• Understanding complication patterns, such as seroma in hip/groin defects, aids in patient selection and management.
