Radial tuberosity

Radial Tuberosity

The Radial Tuberosity is a prominent anatomical feature found on the radius, one of the two large bones of the forearm. It is a bony prominence that serves as the attachment site for the biceps brachii tendon.

Etymology

The term "Radial Tuberosity" is derived from the Latin words "radius" meaning spoke of a wheel, beam, and "tuberositas" meaning lump, bump. The term is used in anatomy to describe a large, rounded protuberance on a bone.

Anatomy

The Radial Tuberosity is located on the medial side of the radius, just below the neck of the radius. It is the point of attachment for the distal biceps tendon. The biceps brachii muscle, which is responsible for the flexion and supination of the forearm, attaches to the radial tuberosity via this tendon.

Clinical Significance

Injuries to the radial tuberosity can occur as a result of trauma, such as a fall on an outstretched hand, or from overuse, such as repetitive lifting or twisting motions. These injuries can lead to pain, swelling, and decreased range of motion in the forearm. Treatment typically involves rest, physical therapy, and in severe cases, surgery.
