Description[edit | edit source]
The radius is one of the two bones that make up the forearm, the other being the ulna. It forms the radio-carpel joint at the wrist and the radio-ulnar joint at the elbow. It is in the lateral forearm when in the anatomical position. It is the smaller of the two bones.
Structure[edit | edit source]
Proximal radius[edit | edit source]
The proximal radius consists of the radial head, neck and tuberosity.
The radial head is cylindrical which articulates with the capitellum of the humerus. The head rotates within the orbicular ligament to produce supination and pronation.[1]
Function[edit | edit source]
The radius' main functions are to provide supination and pronation of the elbow, and all movements of the wrist.
