Ulnar Nerve Anatomy Diagram

The ulnar nerve is most commonly damaged at the elbow, particularly in the cubital tunnel, and at the wrist, often within Guyon’s canal. Repetitive movements, such as prolonged elbow bending or wrist pressure during cycling, typing, or gripping tools, can also cause nerve damage in these areas.

The trigger point for ulnar nerve entrapment is commonly located at the cubital tunnel, near the medial epicondyle of the elbow, or within Guyon's canal at the wrist. These areas are vulnerable due to anatomical constrictions that can compress or irritate the nerve.

Symptoms of ulnar nerve injury include numbness or tingling in the ring and little fingers, weakness in hand grip, and difficulty with finger coordination. Prompt evaluation by a healthcare professional is necessary when these symptoms arise to prevent further nerve damage and initiate appropriate treatment.
