SUMMARY

1. Synovial joint formed proximally by radius & articular disc of distal radio-ulnar joint; distally by scaphoid, lunate & triquetrum.

2. The TFCC separates the radiocarpal joint from the distal radioulnar joint.

3. The capsule is reinforced by multipleligaments, which are thickening of the capsule.


4. Palmar radiocarpal ligament: strong ligaments running transversely between the radius & lunate.

5. Nerve supply: AIN & PIN.


6. Total movement: flexion 80o & extension 60o. Flexion is produced more at the midcarpal joint; extension is produced more at the wrist joint.
