Radius fractures mostly occur at the distal end, which is extremely common, accounting for about 1/10 of normal fractures. It is more common in elderly women, children and young people. The fracture occurs within 2 to 3 cm of the distal end of the radius. It is often accompanied by damage to the radiocarpal joint and the distal radioulnar joint. The radius is one of the two bones of the forearm, divided into one body and two ends. The upper end forms a flat round radial head, with a concave radial head concave on the top of the head, which articulates with the capitellum of the humerus. There is a ring-shaped articular surface around the radial head, which articulates with the radial notch of the ulna. The lower part of the radial head is smooth and narrowed to form the radial neck. There is a large rough protrusion called the radial tuberosity at the inner and lower part of the neck, which is the insertion point of the biceps brachii. The medial edge is sharp, also known as the interosseous ridge, which is opposite to the interosseous ridge of the ulna. The rough surface at the midpoint of the lateral surface is the pronator teres tuberosity. The lower end is particularly enlarged and is approximately cubic. Its distal side is smooth and concave, which is the wrist joint surface, articulating with the proximal carpal bone. The medial surface has an ulnar notch, which articulates with the ulnar head. The lateral surface protrudes downward, called the radial styloid process, which is about 1 to 1.5 cm lower than the ulnar styloid process.
