The Wrist Joint

The Wrist Joint PPT Summary

1. The radiocarpal joint is a biaxial synovial joint connecting the forearm to the hand, involving the radius, scaphoid, lunate, and triquetral bones.
2. Several ligaments, including the palmar and dorsal radiocarpal ligaments and the radial and ulnar collateral ligaments, stabilize the wrist.
3. Flexion, extension, abduction, and adduction are the main movements, with flexion occurring primarily at the midcarpal joint.
4. Fractures such as Colles’ and scaphoid fractures, as well as lunate dislocations, are common wrist injuries, often resulting from falls.
5. The wrist is supplied by branches of the ulnar and radial arteries, with nerve supply from the median, radial, and ulnar nerves.
