The ulnar nerve is susceptible to injury because it passes through the ulnar tunnel posteriorly at the elbow, between the medial epicondyle of the humerus and the olecranon of the ulna, and then across the wrist into the hand. Injuries at the elbow may affect the muscles innervated by the ulnar nerve in the forearm and hand, and injuries at the hand affect the intrinsic muscles supplied by this nerve in the hand. Overuse of muscles and tendons of the forearm or sudden trauma to the nerve within the ulnar tunnel at the elbow can cause the damage to the ulnar nerve.
The major symptoms of this injury may include tingling sensation on the ulnar side of the forearm, weakness and numbness on the ulnar side of the hand, and weakness and difficulty in grasping objects.
Dry needling acupuncture is very helpful for this injury. Needles can be applied to the ulnar tunnel area and to affected muscles and tendons on the forearm and hand. Two treatment sessions per week are recommended.
