Radial tunnel syndrome occurs when the nerve is pinched or compressed as it enters the radial tunnel. This creates unwanted pressure on your radial nerve, often causing nagging pain.
The radial nerve travels down the arm and supplies movement to the triceps muscle at the back of the upper arm. It also provides extension to the wrist, and helps in movement and sensation of the wrist and hand.
The radial tunnel is an area below your elbow. Your radial nerve enters this tunnel of muscle and bone and then travels down to your wrist. When your radial nerve is pinched anywhere in your arm, it can cause pain and weakness.
Risk Factors. The most common cause of radial nerve injury is fracture of the humerus. In such cases, nerve damage may be due to the fracture itself or to a healing callus. Other trauma to the arm—such as may occur in a sports accident or as part of a brachial plexus injury—can also damage the radial nerve.
The radial nerve is part of the peripheral nervous system. The peripheral nervous system sends signals from your brain to your arms and fingers, lower limbs, skin and internal organs.
The radial nerve runs down the underside of your arm and controls movement of the triceps muscle, which is located at the back of the upper arm. The radial nerve is responsible for extending the wrist and fingers.
In tennis elbow, the pain starts where the tendon attaches to the lateral epicondyle. In radial tunnel syndrome, the pain is centered about two inches further down the arm, over the spot where the radial nerve goes under the supinator muscle.
To diagnosis radial tunnel syndrome, clinical examination is more important than paraclinic tests such as electrodiagnsic test and imaging studies. The exact site of the pain which can more specified by rule of nine test and weakness of the third finger and wrist extension are valuable physical exams to diagnosis.
This condition occurs when the nerve is inflamed, trapped, or injured by trauma. The most common reason is trapping (entrapment). Trapping puts pressure on the nerve where it passes through a narrow area. Wrist fractures may injure the median nerve directly.

Ulnar nerve dysfunction is a problem with the nerve that travels from the shoulder to the hand, called the ulnar nerve. It helps you move your arm, wrist, and hand.
