MRCEM Notes

Elbow joint

The elbow is a synovial hinge joint. The joint capsule contains three joints:
  • 1. humeroradial joint between the head of the radius and the capitulum of the humerus
  • 2. humeroulnar joint between the trochlear notch of the ulna and the trochlear of the humerus
  • 3. Proximal radioulnar joint between radial head and radial notch.

The annular ligament allows pronation and supination.
