![]() The fracture appears extra-articular and usually proximal to the radioulnar joint. The plain radiographic series often comprises an AP and a lateral view however, it is not uncommon for an oblique view to be included. Plain films usually suffice, although if there is a concern of intra-articular extension, then CT may be beneficial. As such, in clinical practice, the use of the term Colles fracture with an appropriate description of any associated injuries is sufficient in most instances. One of the more popular is the Frykman classification system, although it fails to distinguish between Smith and Colles fractures as it is based on AP radiographs 2,3. Radiographic featuresĪ number of classification systems exist for distal forearm fractures. Most fractures are therefore dorsally angulated and impacted. The proximal row of the carpus (particularly the lunate and scaphoid) transfers energy to the distal radius, both in the dorsal direction and along the long axis of the radius. ![]() Most Colles fractures are secondary to a fall on an outstretched hand (FOOSH) with a pronated forearm in wrist extension (the position one adopts when trying to break a forward fall). during contact sports, skiing, horse riding 1. Younger patients who sustain Colles fractures have usually been involved in high impact trauma or have fallen, e.g. The relationship between Colles fractures and osteoporosis is strong enough that when an older male patient presents with a Colles fracture, he should be investigated for osteoporosis because his risk of a hip fracture is also elevated 1. They are particularly common in patients with osteoporosis, and as such, they are most frequently seen in elderly women. Colles fractures are the most common type of distal radial fracture and are seen in all adult age groups and demographics.
