In order to make a diagnosis, nerve conduction studies, computed tomography (CT) scans, and magnetic resonance image (MRIs) are often used. In order to treat ulnar tunnel syndrome, it is necessary to identify the source of the pressure on the nerve. Common causes include incorrect hand position while typing, cysts, scars, or other growths in the wrist. If no growth is involved, treatment may involve a splint, anti-inflammatory medications, and rest of the affected hand. If an abnormal growth is the cause of the pressure, surgical removal will be necessary to remove the pressure on the nerve. Following treatment, it will generally take several months for the injured nerve to heal and re-grow.
