  2. Carpal bones - Wikipedia

    en.wikipedia.org/wiki/Carpal_bones

    In contrast, the distal row is more rigid as its transverse arch moves with the metacarpals. [3] Biomechanically and clinically, the carpal bones are better conceptualized as three longitudinal columns: [4] Radial scaphoid column: scaphoid, trapezium, and trapezoid; Lunate column: lunate and capitate; Ulnar triquetral column: triquetrum and hamate

  3. Capitate bone - Wikipedia

    en.wikipedia.org/wiki/Capitate_bone

    The capitate is the largest carpal bone found within the hand. [2] The capitate is found within the distal row of carpal bones. The capitate lies directly adjacent to the metacarpal of the ring finger on its distal surface, has the hamate on its ulnar surface and trapezoid on its radial surface, and abuts the lunate and scaphoid proximally.

  4. Wrist - Wikipedia

    en.wikipedia.org/wiki/Wrist

    In human anatomy, the wrist is variously defined as (1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; [1] [2] (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus [2] and; (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of ...

  5. Trapezium (bone) - Wikipedia

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

    The trapezium is an irregular-shaped carpal bone found within the hand. The trapezium is found within the distal row of carpal bones, and is directly adjacent to the metacarpal bone of the thumb. On its ulnar surface are found the trapezoid and scaphoid bones. [1]: 708

  6. Palmar radiocarpal ligament - Wikipedia

    en.wikipedia.org/wiki/Palmar_radiocarpal_ligament

    The palmar radiocarpal ligament (anterior ligament, volar radiocarpal ligament) is a broad membranous band, attached above to the distal end of the radius, and passing downward to the scaphoid, lunate, triquetrum and capitate of the carpal bones in the wrist.

  7. Intercarpal joints - Wikipedia

    en.wikipedia.org/wiki/Intercarpal_joints

    Joints of the hand, X-ray. The bones in each carpal row interlock with each other and each row can therefore be considered a single joint. In the proximal row a limited degree of mobility is possible, but the bones of the distal row are connected to each other and to the metacarpal bones by strong ligaments that make this row and the metacarpus a functional entity.

  8. Midcarpal joint - Wikipedia

    en.wikipedia.org/wiki/Midcarpal_joint

    The carpal bones are not interlocked solely by their shapes; rather, they are held together by interosseous ligaments and by volar, dorsal, radial, and ulnar ligaments. The ligaments holding the carpal bones to each other, to the distal radius and ulna , and to the proximal ends of the metacarpals can be described as extrinsic, or capsular, and ...

  9. Lunate bone - Wikipedia

    en.wikipedia.org/wiki/Lunate_bone

    The lunate bone (semilunar bone) is a carpal bone in the human hand. It is distinguished by its deep concavity and crescentic outline. It is situated in the center of the proximal row carpal bones, which lie between the ulna and radius and the hand. The lunate carpal bone is situated between the lateral scaphoid bone and medial triquetral bone.
