A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. [1] Symptoms include pain, bruising, and rapid-onset swelling. [1] The ulna bone may also be broken. [1] In younger people, these fractures typically occur during sports or a motor vehicle collision. [2]

The radial inclination of a distal radius fracture is shown in red in image at right. The angle is measured between: [4] [5] A line drawn between the distal ends of the articular surface of the radius on an AP view of the wrist. A line that is perpendicular to the diaphysis of the radius. Radial inclination is normally 21-25°. [6]
Dorsal rotation injury, such as when a drill binds and rotates the wrist instead of the bit, can also cause traumatic injuries. Injury may also occur from a distraction force applied to the volar forearm or wrist. Finally, tears of the TFCC are frequently found by patients with distal radius fractures. [7]
The hand now has a deformed appearance. The only procedure that can be done is the total wrist fusion, where a plate is inserted on the top of the wrist from the radius to the carpals, effectively freezing all flexion and movement in the wrist. Rotation is still possible as it is controlled by the radius and ulna.
The Galeazzi fracture is a fracture of the distal third of the radius with dislocation of the distal radioulnar joint.It classically involves an isolated fracture of the junction of the distal third and middle third of the radius with associated subluxation or dislocation of the distal radio-ulnar joint; the injury disrupts the forearm axis joint.
However, the term now tends to be used loosely to describe any fracture of the distal radius, with or without involvement of the ulna, that has dorsal displacement of the fracture fragments. Colles himself described it as a fracture that “takes place at about an inch and a half (38mm) above the carpal extremity of the radius” and “the ...
The ulna is longer than the radius, but the radius is thicker. The radius is a long bone, prism-shaped and slightly curved longitudinally. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius ...
