  2. Radius (bone) - Wikipedia

    en.wikipedia.org/wiki/Radius_(bone)

    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.

    It joins with the scapula above at the shoulder joint (or glenohumeral joint) and with the ulna and radius below at the elbow joint. Notice : When the arm is spun so that the thumb point to the outside of the body, meaning the palm of the hand looks forward then it is said the hand is supinated.

  4. Ulna - Wikipedia

    en.wikipedia.org/wiki/Ulna

    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.

  5. Forearm - Wikipedia

    Midshaft fracture of the radius and ulna. A fracture of the forearm can be classified as to whether it involves only the ulna (ulnar fracture), only the radius (radius fracture), or both radioulnar fracture. For treatment of children with torus fractures of the forearm splinting appears to work better than casting. [7]

  6. Distal radioulnar articulation - Wikipedia

    en.wikipedia.org/wiki/Distal_radioulnar_articulation

    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.

  7. Head of radius - Wikipedia

    en.wikipedia.org/wiki/Head_of_radius

    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.

  8. Radial tuberosity - Wikipedia

    en.wikipedia.org/wiki/Radial_tuberosity

    Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: . a posterior, rough portion, for the insertion of the tendon of the biceps brachii.

  9. Lunate bone - Wikipedia

    en.wikipedia.org/wiki/Lunate_bone

    The proximal surface of the lunate bone is smooth and convex, articulating with the radius. The lateral surface is flat and narrow, with a crescentic facet for articulation with the scaphoid bone. The medial surface possesses a smooth and quadrilateral facet for articulation with the triquetral bone. The palmar surface is rough, as is the ...
