![]() The distal radius fracture is similar to the common fracture called Colles. ![]() This explains the degree of angulation or displacement of the bone’s normal axis when viewed in an X-ray. Meaning a part of the wrist is either at a loss of axial alignment or tilted. It was initially called a Chauffeur’s fracture because when the chauffeur would turn the crank to start the car, the motor often would cause the crank handle to jerk back. Smith’s fracture is a break involving the distal radius, causing volar angulation. This fracture is classified as an articular fracture. ![]() These are often overlooked and not part of the classification system.Ī Chauffeur’s fracture is also known as a radial styloid fracture or a Hutchinson’s fracture. A Barton’s fracture can be described as volar (more common) or dorsal (less common).Ī die punch fracture is a depression fracture of the lunate fossa of the distal radius fracture that occurs with a vertical load through the lunate. This is an intra-articular fracture and is associated with a dislocation of the radio-carpal joint. These types of fractures are caused by falling backward and an outstretched arm.Īnother type of distal radius fracture is a Barton’s fracture. This is also an extra-articular fracture that is volarly displaced. These fractures occur from a fall forward on an outstretched hand.Ī reverse Colles fracture is also known as Smith’s fracture. A Colles fracture is an extra-articular fracture with a dorsal displacement. In this injury, there is a complete fracture of the distal radius (typically the last two centimeters) usually accompanied by damage to the ulnar collateral ligament or the ulnar styloid process. Many fractures are named based on their fracture location, fracture pattern, and type of displacement.Ĭolles fractures are the most common type of distal radius fracture and account for about 90% of distal radius fractures. The Colles fracture, the most common fracture of the wrist, was first described by Abraham Colles in 1814. Similarly, Intra-articular fractures can be displaced or nondisplaced but occur within the joint. Topic Podcast Images Summary Distal radius fractures are the most common orthopaedic injury and generally result from fall on an outstretched hand.
