What you will learn

  • Locate the radiocarpal joint within the wrist joint complex.
  • Describe its articular surfaces and their exact bony correspondences.
  • Identify the attachments of the capsule and the palmar, dorsal, and collateral ligaments.
  • Relate its two axes of rotation to the four movements of the hand.

Course outline

  1. Wrist landmarks

    An overall map places the radiocarpal joint among the articulations connecting the forearm and hand.

    6 min

  2. Articular surfaces and correspondences

    The antebrachial surface and carpal condyle meet through precise bony correspondences.

    14 min

  3. Capsule and palmar ligaments

    The capsular sleeve and two palmar ligaments provide anterior support to the radiocarpal joint.

    12 min

  4. Dorsal ligament, collateral ligaments, and synovium

    Dorsal and collateral reinforcements supplement the capsule, whose deep surface is lined by synovium.

    15 min

  5. Axes and movements

    Two axes of rotation pair flexion-extension with abduction-adduction of the hand.
