How do elbow ligaments work?

ANSWER

Ligaments are bands of tough elastic tissue around your joints. The two main ligaments around the elbow are the ulnar collateral ligament (UCL) and the lateral collateral ligament. Both connect the bone in your upper arm (called the humerus) to the bone on the pinky side of your forearm (you may know it as the ulna).

The ulnar collateral ligament runs along the inside of your elbow. The lateral collateral ligament goes along the outside.

A third ligament, the annular ligament, circles the top of the other bone in your forearm (called the radius). It holds it against the ulna.
