The radius is a long bone, prism -shaped and slightly curved longitudinally. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone.
Radial tuberosity is visible at upper left of radius.) Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: an anterior, smooth portion, on which a bursa is interposed between the tendon and the bone. Ligaments that support the elbow joint also attach to the radial tuberosity.
The ulna or ulnar bone (pl.: ulnae or ulnas) [3] is a long bone in the forearm stretching from the elbow to the wrist. It is on the same side of the forearm as the little finger, running parallel to the radius, the forearm's other long bone. Longer and thinner than the radius, the ulna is considered to be the smaller long bone of the lower arm.
The carpal bones are the eight small bones that make up the wrist (carpus) that connects the hand to the forearm. The term "carpus" and "carpal" is derived from the Latin carpus and the Greek καρπός (karpós), meaning "wrist". In human anatomy, the main role of the carpal bones is to articulate with the radial and ulnar heads to form a ...
23527. Anatomical terminology. [edit on Wikidata] Lister's tubercle or dorsal tubercle of radius is a bony prominence located at the distal end of the radius. It is palpable on the dorsum of the wrist.
Pain medication, elevation [1] Prognosis. Recovery over 1 to 2 years [1] Frequency. ≈33% of broken bones [2] A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. [1] Symptoms include pain, bruising, and rapid-onset swelling. [1] The ulna bone may also be broken.
The head of the radius has been sawn off and the bone dislodged from the ligament. The proximal radioulnar articulation, also known as the proximal radioulnar joint (PRUJ), is a synovial pivot joint between the circumference of the head of the radius and the ring formed by the radial notch of the ulna and the annular ligament.
35290. Anatomical terminology. [edit on Wikidata] The distal radioulnar articulation[1] (also known as the distal radioulnar joint, [2] or inferior radioulnar joint [1][3]) is a synovial pivot joint between the two bones in the forearm; the radius and ulna. It is one of two joints between the radius and ulna, the other being the proximal ...
