My Ulnar Collateral Ligament (UCL) is located on the inside (medial side) of my elbow.
Here's a more detailed explanation:
-
Location: The UCL resides on the inner aspect of the elbow joint. Think of it as being on the same side as your pinky finger when your arm is in anatomical position (palm facing forward).
-
Attachment Points: It connects the humerus (the bone in your upper arm) to the ulna (one of the bones in your forearm). Specifically, it spans the medial epicondyle of the humerus to the proximal ulna.
-
Function: The UCL is crucial for elbow stability, particularly against valgus stress (forces that push the forearm outwards relative to the upper arm). It prevents excessive gapping of the elbow joint when throwing or performing other overhead activities.
Therefore, when asked "Where is your UCL?", the accurate answer is on the inside of your elbow.
