Generally, it may present with swelling, pain, and decreased range of motion in the wrist. However, the displacement of fracture may be difficult to assess without imaging tests. Smith’s fractures often appear as a deformity on the distal forearm. Note : Low-energy fractures result from falling from standing height or less. Requires a mixture of treatments to reconstruct the damaged elements. Extensive damage to the joint surface, distal radius fragmentation, and shaft damage. falling from a height higher than standing height. The carpal bones are dislocated from the distal radius. This happens in falls from a height, affecting the carpal bones (smaller wrists). The hand and wrist bones can be compressed against the flat surface of the distal radius. As the fracture occurs, the bone shears where one end moves in one direction, the other in the opposite way. Either Smith’s or Colles, such a fracture can be caused by a bending where the hand is extended backwards – vice versa. These are all based on the direction and degree of force applied to the radius in the fall: There are five distinct fracture patterns described by D.L. The Fernandes ClassificationĪ distal radius fracture can be classed based on the mechanism of injury that caused the break. In simple terms, Smith’s has the distal radius pointing forward and backwards with Colles. Colles fractures are the most common type of distal radius fragment. It causes the bone fragment to bend towards the back of the hand. Ī Colles fracture, in contrast, results in dorsal displacement. A Smith’s fracture, as explained, concerns a volar displacement. The displacement of fractures is what differentiates the two. It occurs as a curved or angled break at the wrist joint’s articular surface. The least common type that involves a juxta-articular oblique fracture. It occurs on the articular surface of the radial-ulnar joint, such as the joint surface. Also known as Barton fracture – an intra-articular fracture. A common fracture with a transverse break outside the wrist joint. There are three types of Smith’s fracture, categorised as type I, type II, and type III. Except that it occurs from trauma, such as from falling on an outstretched hand or a flexed wrist. 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. Smith’s fracture is a break involving the distal radius, causing volar angulation. But how will you know if your ‘ deformed wrist ’ relates to this? To give you an idea, this guide will walk you through what Smith’s fracture is. Ī radial fracture is a specific kind of broken wrist. It’s the end closest to the hand that is especially susceptible to radial fracture. And the part of it connected to the wrist joint is called the distal radius. In a normal hand, gently make wrist circles or forearm rotations. It’s one of the outer bones that make up the forearm – the other being the ulna – when viewed with the palm facing forward. In anatomy, the radius bone links the hand to the elbow. Wrist pain may vary, but if you see an unusual deformity on your wrist, it could be a sign of Smith’s fracture.
