Many friends often fall in rainy and snowy weather, and in order to prevent injury, they often use their palms to support the ground, resulting in wrist fractures. The distal radius is the junction between cancellous and dense bone and is more fragile than other parts of the bone, so it is easy to fracture once it is subjected to external force, especially in the elderly and children (both bones are more fragile than young adults). Depending on the mechanism of injury, it can be divided into Colles fracture, Smith fracture and Barton fracture. 1, Colles fracture: also known as extension type distal radius fracture, mostly injured when the wrist joint is in dorsal extension position, palm on the ground, forearm rotation forward, accounting for 90.2% of distal radius fractures. After the injury, the fracture is characterized by local pain and swelling, and the wrist joint movement may be impaired, and the typical deformity may appear: a “silver fork” deformity in the lateral view, and a “spear-like” deformity in the frontal view. Sometimes it can be accompanied by lower ulnar radial joint dislocation and ulnar styloid fracture. 2, Smith fracture: also known as flexion-type distal radius fracture or anti-Colles fracture, often caused by the fall of the wrist flexion, hand back injury, accounting for 7.8% of the distal radius fracture, less common. The fracture is often caused by the dorsal aspect of the wrist, which accounts for 7.8% of distal radius fractures. Sometimes it can be combined with lower ulnar radial joint injury, ulnar styloid fracture and triangular fibrocartilage injury. The direction of the fracture is opposite to that of the extension fracture. 3.Barton fracture: also known as distal radius articular surface fracture with wrist dislocation. When the wrist is dorsally extended, the forearm is rotated forward and the palm of the hand is landed, the violence is transmitted through the wrist bone to fracture the dorsal aspect of the radial joint and the wrist joint is displaced dorsally, accounting for about 2% of distal radius fractures; conversely, when the wrist is flexed and the hand is landed dorsally, a fracture of the palmar articular surface of the distal radius and displacement of the wrist bone to the palmar side can occur, which is less common. Most of these fractures present with a “silver fork” deformity similar to Colles’ fracture and the corresponding manifestations. Emergency management: Avoid movement of the affected wrist, keep it in a normal position, and apply ice to reduce swelling. Treatment: either external fixation by manipulation or internal fixation by surgery. Colles fracture for example: for displaced intra-articular fractures, especially in elderly people with osteoporosis, or in cases of vascular or nerve damage.
