The radial tuberosity is a large bony projection on the medial surface of proximal part of the radius, just distal to the neck. The posterior part of the tuberosity, which forms the majority of its surface, is roughened and serves as the attachment point for the tendon of the biceps brachii. The smaller anterior component of the tuberosity is smoother and has a bursa laying against it.
From the inferior margin of the tuberosity, the oblique line of the radius descends diagonally across the radial shaft.
