Fracture of the radius

Radial fractures occur mostly in the distal end and are extremely common, accounting for about one-tenth of the usual fractures. More common in older women, children and young people. Fractures occurred within 2 to 3 cm of the distal radius. Often accompanied by radial wrist and lower ulnar radial joint damage. The radius, one of the forearm's double bones, is divided into one body and two ends. The upper end forms a flat round radial head, and there is a concave radial head recess above the head, which is related to the small head of the humerus. There is a circular articular surface on the periphery of the radial head, which is related to the radial incision of the ulna. The lower part of the radius head is smoothly tapered to the radius neck, and there is a large rough bulge at the inner and lower part of the neck called the radial trochanter, which is the resistance of the biceps brachii. The medial margin is sharp, also known as the interosseous condyle, opposite the interosseous condyle of the ulna. The rough surface at the midpoint of the lateral surface is the pronator muscular trochanter. The lower end is particularly swollen and approximates a cuboid. Its distal side is smooth and concave, and it is the wrist joint surface, which is related to the proximal carpal bone. There is a ulnar notch on the inner side, which is related to 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.
