![]() Osteoporosis associated with aging increases the risk of these fractures in elderly individuals and also increases the risk in women, who are more commonly affected by osteoporosis. Interestingly, ages 19 to 49 years old make up the least common age group for these injuries. In pediatrics, fractures often occur around the time of puberty due to low bone mineralization. EpidemiologyÄistal radius fractures occur in people of all ages and, more often, in females. Distal radius fracture has a bimodal distribution in young athletes from high-energy injuries, as in sporting activities and motor vehicle accidents, and the elderly from low-energy trauma. As a result of these forces through the wrist, dorsal displacement and comminution occur. Tension on the volar aspect of the wrist causes bending and compressive forces. This condition is also known as a "fall on outstretched hand injury," referred to by the acronym "FOOSH injury." The severity of the injury is usually determined by the position of the wrist when injured as well as the amount of force of the trauma. The Colles fracture is most commonly caused by a fall, landing on an outstretched hand with the wrist in dorsiflexion. The ulnar column ( TFCC + Distal ulna): Stabilizes the DRUJ and forearm rotation. The intermediate column (Lunate fossa): is responsible for load transmission from the carpus to the forearm. It acts as a load-bearing strut for wrist ulnar deviation.It works as a buttress for radial translation of the carpus and holds it to length radially for even load distribution across the scaphoid and lunate fossae.It has the attachment of the brachioradialis tendon, long radiolunate ligament, and radioscaphocapitate ligament, which prevents ulnar translation of the carpus.T he radial column ( radial styloid + scaphoid fossa): The distal radius has three columns radial, intermediate and ulnar columns. It has the following articulations scaphoid ( scaphoid fossa), lunate ( lunate fossa), and distal ulna ( ulnar or sigmoid notch). The distal radius bears 80% of the axial load. These distal radius fractures are often caused by falling on an outstretched hand with the wrist in dorsiflexion, causing tension on the volar aspect of the wrist, causing the fracture to extend dorsally. The term Colles fracture is often used eponymously for distal fractures with dorsal angulation. The Colles fracture is defined as a distal radius fracture with dorsal comminution, dorsal angulation, dorsal displacement, radial shortening, and an associated ulnar styloid fracture. Named after Abraham Colles, who first described a distal radius fracture in 1814 at the Royal College of Surgeons in Dublin, the Colles fracture is one of the most common fractures encountered in orthopedic practice representing 17.5 % (one-sixth) of all adult fractures presenting to the emergency department.
