What Is the Medial Epicondyle?
The medial epicondyle is a bony protrusion that can be felt on the inside part of the elbow. Part of the upper arm bone, or humerus, it occurs at the bottom of the bone where the humerus meets the ulna at the elbow. It is larger and further back on the bone than its counterpart — the lateral epicondyle. The medial epicondyle provides attachment of the ulnar collateral ligament to the pronator teres muscle, near the back of the elbow. When the ulnar nerve that runs along the back of this bone is hit, it is frequently referred to as hitting the funny bone.
