![]() ![]() Patient is unable to function at home (e.g.Risk or concern for compartment syndrome.Most can be treated with orthopedic follow up within 1 week There are several popular eponyms used to define fractures of the distal radius.If severe pain with pronation/supination, then sugar tong splint.Intra-articular displacement or step-off > 2mm.Operative fixation is recommended for fractures with post-reduction :.Always target optimal (anatomic) fracture reduction.For example with a fracture with dorsally angulated fragments, establish axial traction, then slightly bending the dorsal fragment even more dorsally while maintain traction, then reverse pressure to reduce the distal fragment volarly and back out to length, all while maintaining traction.Continue to maintain axial traction throughout manuver.Although recreating the injury briefly exaggerates the existing deformity, this maneuver "unlocks" any periosteal sleeve folded into the fracture site (which can be critical in achieving reduction).Recreate, then reverse, mechanism of injury.Axial traction: Manual or finger traps with hanging weights, if available.Consider even if operative management is expected (to reduce pain and swelling).Most angulated and/or displaced distal radius requires closed reduction and placement of a sugar-tong splint.Colles fractures are the most common type of distal radius fracture. Neurovascular compromise from fracture requires emergent reduction and/or orthopedic intervention A Smith’s fracture is a volar displacement fracture where the fragment of the radius that has broken off projects towards the palm side of the hand, while a Colles fracture results in dorsal displacement, causing the bone fragment to bend towards the back of the hand.Open fractures require immediate IV antibiotics and urgent surgical washout.It is also known as a reverse Colles fracture since the more common Colles fracture features a dorsal displacement of the distal fracture fragment. due to tensile stress (Colles and Smith fractures) an the opposite undergoes a. Introduction A Smith fracture is an eponym for an extraarticular fracture of the distal radius featuring a volar displacement or angulation of the distal fragment. It can show the presence of a distal radial fracture with volar angulation, the fracture location (extra-, juxta-, or intra-articular), the degree of angulation, and displacement. The two primary x-ray views of the wrist, a posteroanterior and a lateral. Radial tuberosity – A bony projection, which serves as the place of attachment of the biceps brachii muscle.Displaced, intra-articular distal radius fracture. 1 Diagnosis X-rays AP and the lateral radiograph of the wrist can diagnose the fracture.Neck – A narrow area of bone, which lies between the radial head and radial tuberosity.It is thicker medially, where it takes part in the proximal radioulnar joint. Head of radius – A disk shaped structure, with a concave articulating surface.Important bony landmarks include the head, neck and radial tuberosity: This fracture is often distinguished from the Colles and Smith fractures by the presence of intraarticular radiocarpal joint involvement 8, 9. A triangular fragment of the dorsal or volar margin of the distal radius is sheared off and displaced in a dorsal or volar direction with the carpus. The proximal end of the radius articulates in both the elbow and proximal radioulnar joints. dorsal or volar fracture-dislocation of the wrist. In this article, we shall look at the bony landmarks and osteological features of the radius. Distal radioulnar joint - An articulation between the ulnar notch and the head of the ulna.Wrist joint - An articulation between the distal end of the radius and the carpal bones.A Colles fracture occurs when the broken end of the radius tilts upward. This fracture was first described in 1814 by an Irish surgeon and anatomist, Abraham Colles hence the name Colles fracture. ![]() It is the opposite of a Colles fracture, as the distal fragment is displaced. Cause The most common cause of a distal radius fracture is a fall onto an outstretched arm. One of the most common distal radius fractures is a Colles fracture, in which the broken fragment of the radius tilts upward. Proximal radioulnar joint - An articulation between the radial head, and the radial notch of the ulna. Smiths fracture A fracture caused by falling onto the back of the hand.Elbow joint - Partly formed by an articulation between the head of the radius, and the capitulum of the humerus.The radius pivots around the ulna to produce movement at the proximal and distal radio-ulnar joints. A Smith fracture is an eponym for an extraarticular fracture of the distal radius featuring a volar displacement or angulation of the distal fragment. It lies laterally and parallel to ulna, the second of the forearm bones. The radius is a long bone in the forearm. Fig 1.0 - The anatomical position of the radius. ![]()
