8 paź 2023 · Colles fractures are very common extra-articular fractures of the distal radius that occur as the result of a fall onto an outstretched hand. They consist of a fracture of the distal radial metaphyseal region with dorsal angulation and impaction, but without the involvement of the articular surface.
Une fracture de Colles est une fracture du radius distal nommée d'après Abraham Colles, qui l'a décrite pour la première fois en 1814. Le mécanisme de la blessure est une chute sur la main tendue (blessure FOOSH) et elle est fréquemment observée dans les services d'urgence.
The term Colles fracture is classically used to describe a fracture at the distal end of the radius, at its cortico-cancellous junction. However, the term now tends to be used loosely to describe any fracture of the distal radius, with or without involvement of the ulna, that has dorsal displacement of the fracture fragments.
Age: 13 years. Gender: Male. x-ray. Frontal. Lateral. There is a minimally displaced fracture through the distal left radial metaphyseal region with dorsal angulation of the distal fracture component, keeping with a Colles fracture. Accompanied ulnar styloid fracture is also evident.
31 lip 2023 · 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. The term Colles fracture is often used eponymously for distal fractures with dorsal angulation.
The eponym “Colles’ fracture” has been used to describe all distal radius fractures, though that name refers specifically to fractures that are angulated dorsally. Figure 1: Colles fracture. (From radiopaedia.org http://bit.ly/1P0PjGJ) Structure and Function. The distal radius forms the proximal side of the wrist joint.
Background. Distal radial metaphysis fracture that is dorsally displaced and angulated. Fracture line may extend into radioulnar or radiocarpal joint ("die-punch" fracture) Occurs due to FOOSH. Ulnar styloid fracture is often present and suggests injury to TFCC. Clinical Features. Colle's fracture on physical exam.
