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[1]. The head rotates within the annular ligament to produce supination and pronation.[2]
Function[edit | edit source]
The radius' main functions are to provide supination and pronation of the elbow, and all movements of the wrist.
