Radial tuberosity

Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into:

• a posterior, rough portion, for the insertion of the tendon of the biceps brachii.^[1][2][3][4]
• an anterior, smooth portion, on which a bursa is interposed between the tendon and the bone.
