The proximal row consisted of the radiale (below the radius), the ulnare (below the ulna), and the pisiform (a small element below the ulna and lateral to the ulnare). The distal row consisted of five elements sitting above the five metatarsals, which are denoted as distal carpals 1–5. The middle row is represented by a single element, the ...
De Quervain syndrome causes pain over the styloid process of the radius. [3] [4] This is due to the passage of the inflamed extensor pollicis brevis tendon and abductor pollicis longus tendon around it. [4] [5] The styloid process of the radius is a useful landmark during arthroscopic resection of the scaphoid bone. [6]
The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus. The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna , narrow in the rest of its extent, which is embraced by the annular ligament .
Lateral supracondylar ridge of the humerus and the orbicular ligament of the radius: Insertion: Distal radius (radial styloid process) Artery: Radial recurrent artery: Nerve: Radial nerve (C5-C8 & T1) Actions: Flexion of elbow, supination and pronation of the radioulnar joint to 90° Identifiers; Latin: musculus brachioradialis: TA98: A04.6.02. ...
The ulna is longer than the radius, but the radius is thicker. 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 ...
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 radioulnar articulation.
Theropod paleopathology is the study of injury and disease in theropod dinosaurs.In 2001, Ralph E. Molnar published a survey of pathologies in theropod dinosaur bone that uncovered pathological features in 21 genera from 10 theropod families.
Temporary hemiepiphysiodesis has also been used to treat deformities around the hips and ankles [1] [2] [3] and in the upper extremity growth plates such as the distal radius growth plate. [4] Temporary hemiepiphysiodesis works through arresting or inhibiting the physeal growth at one hemi-side of the growth plate.
