![]() ![]() The ulnar column ( TFCC + Distal ulna): Stabilizes the DRUJ and forearm rotation.Ĭopyright © 2023, StatPearls Publishing LLC. 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. Reflex sympathetic dystrophy, lesion of the n. Open and close reduction techniques produce similar results in treat-ment of Colles fracture. It has the attachment of the brachioradialis tendon, long radiolunate ligament, and radioscaphocapitate ligament, which prevents ulnar translation of the carpus. Flexion fracture of forearm is called as Smith frac-ture or reverse Colles fracture, where distal fragment is angulated volary. 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). 1847 Robert William Smith described the characteristics of Colles fracture in his book A Treatize on Fractures in the Vicinity of Joints and on Certain Forms of Accidents and Congenital Dislocations. 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. Smith Fracture: less common than a Colles Fracture, a Smith fracture break is in the opposite direction, with the broken fragment directed the other way, towards the palm.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. ![]() In this type of fracture, the part of the radius that broke is tilted upwards toward the backside of the hand These are:Ĭolles Fracture: A Colles Fracture will be the direct result of falling straight onto the palm causing a FOOSH injury (Fall On Outstretched Hand). The two most common types of Distal Radius fractures are categorized by the angle of the break. Fractures may be even more severe and cause the bone to break in multiple places and essentially splinter the bone. Fractures that are open, unstable, comminuted, and/or accompanied by neurovascular injury are usually managed surgically. A Broken bone can be displaced or nondisplaced, which will determine if the fracture is stable or unstable. Nondisplaced stable fractures are typically managed with closed reduction and immobilization. A Distal Radius Fracture can present in many forms, and will guide the strategy of treatment that is decided on in order for healing and recovery to take place. While a Broken Wrist can be a break of any of these bones, by far the most common site of break is at the distal radius bone. Colles fracture, by Smith 1847 Smith refined the Colles’ anatomical description with corrections footnotes: ()The situation of the fracture is not so high as Mr. Also, bones of the wrist are considered to be the distal (further away from the body) forearm bones, the radius and ulna. The broken bone in the fracture usually points upward. These include all of the carpal bones, which are the small bones that join the forearm to the rest of the hand and provide the wrist with a good deal of mobility. W.: A Treatise on Fractures in the Vicinity of Joints, Dublin, Hodges and Smith New York, Samuel and William Wood, 1854. When the bone breaks 1 inch from the wrist, it’s called a distal radius break. The Smith fracture was named by Irish surgeon Robert William Smith in 1847, who incidentally. It is also known as a reverse Colles fracture since the more common Colles fracture features a dorsal displacement of the distal fracture fragment. A Broken Wrist is a fracture of any one of the bones that comprise the wrist. A Smith fracture is an eponym for an extraarticular fracture of the distal radius featuring a volar displacement or angulation of the distal fragment. ![]()
