Radius

Os radii

The radius is shorter than the ulna but widens distally. The radial head articulates with the capitulum of the humerus and the radial notch of the ulna. The radial tuberosity provides attachment for the biceps brachii tendon. The styloid process is at the distal end.

Funktion

The lateral bone of the forearm that rotates around the ulna during pronation and supination. Articulates with the carpal bones at the wrist, bearing most of the load transmitted to the hand.

Klinische Bedeutung

Distal radius fractures (Colles' fracture) are the most common fractures of the upper extremity. Radial head fractures occur from falls on outstretched hands. The radial artery at the wrist is used for pulse measurement.
