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.
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.
Gender: Female. From the case: Colles fracture. x-ray. Radiographs revealed an extra-articular fracture of the distal radius with dorsal displacement. This describes a Colles fracture.
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.
A Colles’ fracture, though at times used imprecisely to refer to all distal radius fractures, is the term for a transverse, dorsally displaced and angulated distal radius fracture about one inch proximal to the wrist.
30 paź 2023 · Colles fracture typically occurs when a person falls and uses a pronated hand and outstretched arm to try to break the fall. In this position, the wrist is usually at 40-90° in dorsiflexion. The pressure from the fall over-extends the hand and breaks the radius just above the wrist.
Pediatric Colles Fracture. Etiology: fall on outstretched hand. Imaging: extra-articular fracture of distal radial metaphyseal region with dorsal angulation and impaction but without the involvement of articular surface, ulnar styloid fracture in up to 50%.
