Elbow

​

The elbow is a hinge joint which consists of two articulations; one between the humerus and ulna (ulnohumeral joint) allowing flexion, and one between the humerus and radius (radiocapitellar joint) allowing rotation of the forearm.

​

Surrounding the bones are a series of ligaments. There is a complex of ligaments on the external (lateral) aspect of the elbow and one on the internal (medial) aspect. These help support and stabilise the elbow during motion and loading.

​

Muscles surround the elbow joint. These both control elbow motion and wrist motion.
