Colles fracture11/25/2023 Commonly caused by a fall on to an outstretched hand, signs and symptoms. Since exaggerated volar flexion is a position in which normal function is almost impossible, it is important that the wrist be placed in as nearly a straight line as is consistent with maintenance of the reduction. A Colles fracture is a break in the radius bone of the forearm, just above the wrist. The doctor will take an X-ray of the wrist. The eponym Colles fracture has been used to describe all distal radius fractures, though that name refers specifically to fractures that are angulated. A broken wrist usually causes pain and swelling, and frequently causes a deformity, causing the wrist to look bent. It is frequently necessary that this be done, but in the majority of cases, immobilization may be carried out with the wrist straight or in slight flexion. This fracture was first described by an Irish surgeon and anatomist, Abraham Colles, in 1814 hence the name, 'Colles ' fracture. ![]() The fracture is usually immobilized with the wrist in marked volar flexion, in order to obtain reduction of these deformities. In reducing the fracture, it is extremely important that the posterior displacement and angulation be corrected, so that there will be a full range of motion in volar flexion. Colles fracture is defined as a fracture of the distal third of the radius, in which the fragment moves posteriorly without extending to the articular surface. What is a Colles fracture A Colles fracture is a break of one of the forearm bones (the radius) near the wrist joint. The injury results from a fall on the outstretched hand, and this accounts for the type of deformity produced. ![]() The usual deformity is threefold: posterior displacement, posterior angulation, and radial deviation of the hand at the wrist. (2.54 cm.) of the articular surface of the radius, which may or may not be accompanied by a fracture of the styloid process of the ulna. A true Colles Fracture is a complete fracture of the radius bone of the forearm close to the wrist resulting in an upward (posterior) displacement of the radius and obvious deformity. Colles' fracture is a fracture of the lower end of the radius, within 1 in. Colles Fracture is a complete fracture of the radius bone of the forearm close to the wrist resulting in an upward (posterior) displacement of the radius and obvious deformity.
