Anatomy-Upper Limb

WRIST-JOINT

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.
