This compression syndrome of the radial nerve in the region of the elbow can be caused by trauma, ganglia, lipomas, bone tumors or arthritis of the elbow joint.

The radial tunnel syndrome is a compression of the radial nerve at the proximal forearm This compression syndrome of the radial nerve may be caused in the region of the elbow by trauma, ganglia, lipomas, bone tumors or arthritis of the elbow joint. Symptoms and complaints Lancinating pain in the dorsal forearm and lateral aspect of the elbow is the main symptom. It is triggered by the attempt, wrist and fingers to stretch and supinating the forearm. A disturbance of the sensibility is rather unusual because the radial nerve is a motor nerve at this level. This disorder is sometimes mistaken for a tennis elbow (lateral epicondylitis). Is a weakness of the extensor muscles of Erstbefund, this speaks for posterior paralysis of the interosseous nerve. Diagnosis Clinical evaluation Lateral epicondylitis can cause similar pain around the lateral epicondyle, but has no positive Tinel’s sign and tenderness along the radial nerve on. Therapy splinting by splinting the strong and repeated supination and dorsiflexion of the wrist can be avoided, thereby reducing the pressure on the nerve. If a case hand or a weakness of the finger extensors developed or not results of the conservative treatment within 3 months a significant relief, a surgical decompression may be necessary.
