McGregor Pedicled Groin Flap Surgical Technique for Reconstruction of Hand Skin Defects

Abstract

McGregor flap is an axial pattern distant flap, also known as pedicled groin flap. It is a highly reliable flap for large tissue defects of the hand (dorsal or palmar surfaces), the wrist, or the forearm, up to the elbow. Based on its own vascular pedicle, with a constant blood supply, it can be easily transferred with acceptable aesthetic outcomes. Therefore, the McGregor flap remains a flap of choice in the therapeutic arsenal of emergency hand surgery, especially when no other solution can be offered. In the following description, we try to present the anatomical landmarks as well as the different operating steps allowing the safe and easy performance of the aforementioned flap.
