WRIST-JOINT

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 multiple ligaments, which are thickening of the capsule. 
4. Palmar radiocarpal ligament - strong ligaments running transversely b/w radius & lunate. 
5. Nerve supply - AIN & PIN. 
6. Total movement - flexion 80 degrees & extension 60 degrees. Flexion is produced more at the midcarpal joint; extension is produced more at the wrist joint.
