common peripheral nerve injuries affecting the wrist, hand, fingers and forearm include: • Carpal tunnel syndrome: This syndrome occurs when the nerves passing through the arm’s carpal tunnel (space between ligaments and bone in the forearm) become traumatized by pressure. This is the most commonly diagnosed pinching” nerve condition. • Cubital tunnel syndrome: This condition is caused by increased pressure to the ulnar nerve—positioned right next to the interior elbow funny bone.” The nerve has very little padding to protect it, so it is particularly vulnerable to pressure—for example, from propping the elbow on an armrest. • Radial tunnel syndrome: This condition occurs when the radial nerve—originating at the neck and traveling along the back of the arm to the hand—is pinched. The condition is worsened by repetitive tasks that require you to twist the wrist, as the nerve passes under the muscle used to perform this function. In all three cases, the condition is diagnosed with electromyography or another similar nerve conduction test. Surgery is used to relieve pressure to the compromised nerve only after behavior modification techniques have failed to give the patient relief.
