31 lip 2024 · The radius (plural: radii) is one of the two long bones present in the forearm, located laterally in the supinated anatomical position. It has a smaller proximal end and enlarges to a larger distal end (opposite to the ulna). Gross anatomy. Osteology.
18 kwi 2022 · The radial head is the proximal articular surface of the radius and prone to dislocation in childhood and fracture in adults. It is palpable on the lateral side of the elbow, immediately distal to the lateral epicondyle of the humerus. Gross anatomy. The radial head forms part of the elbow joint.
31 lip 2024 · Distal radial fractures are a heterogeneous group of fractures that occur at the distal radius and are the dominant fracture type at the wrist. These common fractures, representing ~15% of all fractures 7, usually occur when significant force is applied to the distal radial metaphysis.
18 lis 2022 · In this article, we review the relevant anatomy, pathologic conditions, classification, and imaging of common disorders, emphasizing features that influence clinical and preoperative decision making to aid in radiologic interpretation and reporting.
12 sty 2008 · Dorsal-type Barton's is a fracture-dislocation of the dorsal rim of the radius. Dislocation of the radiocarpal joint is the hallmark of Barton's fractures. These are shear type fractures of the distal articular surface of the radius with translation of the distal radial fragment and the carpus.
26 lip 2021 · Radius. Overview. The radius is a long bone in the forearm. It lies laterally and parallel to the ulnar. The long narrow medullary cavity is enclosed in a strong wall of compact bone, which is thickest along the interosseous border and thinnest at the extremities. Surfaces. Volar (anterior) surface. Rough and irregular.
The radius and ulna form an anatomical unit, joined throughout their length by an interosseous ligament and stabilised at the elbow and wrist, thus forming a ring. If there is a fracture of the shaft of one of these bones with visible shortening, there will likely be dislocation at the wrist or elbow of the other.
