The ulnar nerve starts in the neck, crosses the elbow, and ends in fingers. The elbow’s inside part has a narrow 4-millimeter passageway between the bones and tissue called a cubital tunnel. CTS occurs when the ulnar nerve is injured and becomes inflamed, swollen, and irritated.
Causes The ulnar nerve is relatively superficial at the point of the medial epicondyle. Due to its anatomical position, the ulnar nerve gets stretched during the flexion of the elbow joint. Repetitive elbow flexion and extension cause damage and irritation to the ulnar nerve. It may be caused due to: An increase in pressure on the ulnar nerve due to frequent bending of the elbow, leaning on the elbow or any injury to this area Bone spurs, arthritis, and…
