What type of fracture is a Colles fracture?

A Colles fracture specifically refers to a type of fracture that occurs in the distal radius near the wrist. This injury is typically characterized by a fracture that results from a fall onto an outstretched hand, leading to a dorsal angulation and often shortening of the radius. It is particularly common in older adults, especially post-menopausal women, due to osteoporosis, but it can occur in individuals of all ages.

Understanding the mechanism behind a Colles fracture is essential for effective management and treatment. The typical presentation includes a "dinner fork" or "bayonet" appearance of the wrist, which is a hallmark sign that helps in diagnosing this fracture. By identifying this specific type of fracture, healthcare providers can implement the appropriate treatment measures, which may include immobilization with a cast or sometimes surgical intervention, depending on the severity and complexity of the fracture.
