2. Introduction Also called as Wrist Joint. An Ellipsoid & Synovial joint . BONES: Formed by proximal row of Carpal bones- Scaphoid, Lunate and Triquetrum and distal end of radius, and articular disk. Carpal bones form a convex surface which attaches to the concave surface of radius and articular disk by tendons.

3. Ligaments- Fours ligaments 1.Palmar Radiocarpal- on palmar(anterior) side of hand -increases stability & it ensures that hand follows forearm during supination. 2.Dorsal Radiocarpal- on dorsum(posterior)side of hand - increases stability & ensures that hand follows forearm during pronation. 3.Ulnar Collateral- Runs from ulna to triquetrum and pisiform - prevents excessive lateral joint displacement. 4.Radial Collateral-Runs from radius to scaphoid and trapezium - prevents excessive lateral joint displacement. Movements - 1.Flexion 2.Extension 3.Adduction 4.Abduction

4. 1.Scaphoid Fracture - direct axial compression or hyperextension of wrist -diagnosed as pain or swelling at the base of thumb -occurs commonly in young males and athletes. Injuries- 2.Lunate Dislocation -Due to fall from a height or and automobile collision -lunate bone get dislocated -swelling, pain and limited motion of wrist and hand.
