It separates from the main trunk of the ulnar nerve about 5-12 cm proximal to the level of the wrist crease. Ulnar nerve subluxation is a condition where the ulnar nerve slides back and forth from its normal position behind the medial epicondyle (the bony prominence on the inside of the elbow) to in front of it. Positive ulnar variance indicates a longer ulna compared to the radius and a negative ulnar variance indicates a shorter ulna. There is no palpable subluxation at the medial elbow with flexion and extension. Metacarpal Fractures are the most common hand injury and are divided into fractures of the head, neck, or shaft.
