The extensor digitorum brevis as a muscle island flap

Area of Science:

• Orthopedic Surgery
• Plastic Surgery
• Anatomy

Background:

• Soft-tissue defects in the lower extremity, particularly around the lateral malleolus and ankle, pose reconstructive challenges.
• Local muscle flaps offer a potential solution for coverage, preserving function and minimizing donor site morbidity.

Observation:

• The extensor digitorum brevis muscle's anatomy and vascular supply are suitable for its use as a local muscle island flap.
• Dissection techniques allow for the elevation of this muscle as a pedicled flap.

Findings:

• The extensor digitorum brevis muscle flap was successfully utilized for soft-tissue defect coverage in a patient with a lateral malleolus and ankle wound.
• This demonstrates the flap's efficacy in reconstructing lower extremity defects.

Implications:

• The extensor digitorum brevis muscle flap is a valuable reconstructive option for lateral malleolus and ankle soft-tissue defects.
• This technique may improve outcomes for patients requiring lower extremity wound coverage.
