Fig.2From: The free flap based on a single proximal perforator of the radial artery: ultrasonography study and clinical applications in reconstruction of soft tissue defects in fingerLocation of the perforator of the radial artery in the proximal forearm. P perforator; Dp the distance from location of the perforator to the elbow crease; DE–W the distance from the elbow crease to the wrist crease. Perforator Location = Dp/DE–W × 100% the relative distance of the perforator location beyond the elbow creaseBack to article page
