Application of Groin Flap

Introduction: The groin flap, first described by McGregor and Jackson in 1972, is recognized as the first successful free cutaneous flap. This flap is characterized by its long, narrow pedicle based on the superficial circumflex iliac artery (SCIA) and vein, offering a reliable option for various reconstructive procedures. Methods: A comprehensive review of anatomical and clinical literature regarding the groin flap was conducted. Key anatomical features, including the vascular supply, venous drainage, innervation, and potential donor site complications, were analyzed. Surgical techniques for harvesting the flap were also discussed. Results: The groin flap receives arterial supply primarily from the SCIA, and venous drainage by its venae comitantes. The flap’s sensory innervation is provided by the lateral cutaneous nerve of T12, with the potential for motor nerve inclusion if the sartorius muscle is harvested. The groin flap presents a versatile option for reconstructive surgery, particularly for upper extremity defects and lower abdominal repairs. Conclusions: The groin flap is a valuable surgical option in reconstructive surgery, offering consistent vascular supply and versatility in design.
