  Ulnar nerve - Wikipedia, the free encyclopedia
The ulnar nerve is a nerve that in humans runs down the arm and forearm, and into the hand.
The ulnar nerve comes from the lower cord of the brachial plexus, and runs posterior to the humerus down the arm, going behind the medial epicondyle at the elbow.
Muscles in the hand supplied by the ulnar nerve include the medial two lumbrical muscles, the muscles of the hypothenar eminence (opponens digiti minimi, flexor digiti minimi and abductor digiti minimi), the interossei (palmar and dorsal groups) and the adductor pollicis muscle.

This part of the ulnar nerve is known as the funny bone for two reasons: because of its proximity to the humerus (and the similar word "humorous".) and because of the mild pain and tingling throughout the forearm associated with sudden compression of the nerve at this point.

 Median nerve - Wikipedia, the free encyclopedia
The proximal part of the palm is supplied by a palmar branch,the palmar cutaneous brach of the median nerve which leaves the nerve proximal to the wrist creases.
The muscular branches (rami musculares) are derived from the nerve near the elbow and supply all the superficial muscles on the front of the forearm, except the Flexor carpi ulnaris.
In the palm of the hand the median nerve is covered by the skin and the palmar aponeurosis, and rests on the tendons of the Flexor muscles.

As the nerve exits the flexor carpi ulnaris, it perforates a fascial layer between the flexor digitorum superficialis and the flexor digitorum profundus.
The course of the nerve is palpated in the forearm to the wrist.
Once the nerve has been visualized from about 8 cm proximal to the medial epicondyle to 6 cm distal to the epicondyle, the distal portion of the medial intermuscular septum, the fibroaponeurotic roof of the epicondylar groove, the Osborne ligament, and the fascia of flexor carpi ulnaris are incised, freeing the ulnar nerve.

 Ulnar nerve dysfunction
Ulnar nerve dysfunction involves impaired movement or sensation in the wrist and hand caused by damage to the ulnar nerve.
Ulnar nerve dysfunction is a common form of peripheral neuropathy.
The ulnar nerve is near the surface of the body where it crosses the elbow, so prolonged pressure on the elbow or entrapment of the nerve may cause damage.

 Orthosports - Orthopaedic & Sports Medicine Physicians - Ulnar Nerve Entrapment
The ulnar nerve is an important nerve because it supplies feeling to the little and ring fingers of the hand and activates many of the small muscles in the hand (allowing strong gripping of objects in the hand).
Although the nerve is squashed around the elbow, most symptoms occur in the hand and fingers because the ulnar nerve controls movement and feeling.
You may be sent for nerve conduction studies to confirm the diagnosis or to act as a baseline test to monitor the nerve's recovery.

 Closed Claims: Perioperative Ulnar Nerve Injury
Of 1,541 total anesthesia claims in the database in 1990, 15 percent were for nerve injury with 34 percent of the total nerve injuries being of the ulnar nerve.
Anesthesia-related perioperative ulnar nerve injury is often ascribed to malposition of the elbow with the ulnar nerve being compressed during surgery on a hard surface, or stretched in some fashion.
Further evidence against an all-inclusive malposition nerve compression theory of causation is the fact that eight claims for perioperative ulnar nerve injury were from patients who had spinal, epidural or local anesthesia for lower body surgical procedures.

Based on your history of a possible stretch injury it is more probable to be the site of injury, although with only sensory involvment clinically or by EMG this is less certain as anywhere form the distal sensory brancy in the forearm and higher may have been affected.

 Nerve Compression Syndrome - Detroit, Michigan, Henry Ford
The ulnar nerve starts at the side of the neck and joins three main nerves that travel down the arm to the hand.
After passing through the canal, the ulnar nerve branches out to supply feeling to the little finger and half the ring finger, as well as the small muscles of the hand.
Treatment is avoidance of pressure on the nerve at the elbow and avoidance of extreme elbow flexing.  If there is denervation, surgery to relieve the compression may be necessary.
