Tinels sign involves tapping which anatomical groove?

Explanation:
Tinels sign is a percussion test used to detect irritated nerves. At the elbow, you tap over the ulnar nerve where it sits in a groove between the olecranon and the medial epicondyle. If the nerve is irritated, tapping here reproduces tingling or paresthesias along the ulnar distribution down the forearm and into the hand (little finger and the ulnar side of the ring finger), which points to a ulnar neuropathy such as cubital tunnel syndrome. The carpal tunnel at the wrist tests the median nerve, and the supracondylar region is not the typical elbow site for this nerve in question.
