Distal radius fractures are common, [3] and are the most common type of fractures that are seen in children. [4] Distal radius fractures represent between 25% and 50% of all broken bones and occur most commonly in young males and older females. [3] [2] A year or two may be required for healing to occur. [1]
A Torus fracture, also known as a buckle fracture is the most common fracture in children. [1] It is a common occurrence following a fall, as the wrist absorbs most of the impact and compresses the bony cortex on one side and remains intact on the other, creating a bulging effect. [ 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]

A Smith's fracture, is a fracture of the distal radius. [1] Although it can also be caused by a direct blow to the dorsal forearm [2] or by a fall with the wrist flexed, the most common mechanism of injury for Smith's fracture occurs in a palmar fall with the wrist joint slightly dorsiflexed. [3] Smith's fractures are less common than Colles ...
- A line perpendicular to the distal articular surface of the lunate bone. It should normally be 30°-60°. [1] Dorsal intercalated segment instability (DISI) is a deformity of the wrist where the lunate bone angulates to the dorsal side of the hand. [2] [3]
De Quervain syndrome causes pain over the styloid process of the radius. [3] [4] This is due to the passage of the inflamed extensor pollicis brevis tendon and abductor pollicis longus tendon around it. [4] [5] The styloid process of the radius is a useful landmark during arthroscopic resection of the scaphoid bone. [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]
