§Radial tunnel syndrome is most often caused by repetitive twisting and torquing of the elbow, especially the repetitive motion of the throwing arm.

Repeated pronation and supination of the elbow, seen often in pitchers, can aggravate the radial nerve.

Eventually scarring or an extra ligament traps the radial nerve in the promimal elbow.
The most common sports in which this injury occurs are tennis, racquetball, golf, baseball, and other throwing sports.
•in radial tunnel syndrome, the motor branch (the part of the nerve that causes the muscles to move) of the radial nerve becomes entrapped.
Symptoms of pain and numbness in the back of the hand and forearm occur with weakness in extending to the wrist and fingers.
The athlete might at fist appear to have tennis elbow, but the injury does not improve with usual treatment.
Further examination reveals neurological deficits in the forearm and back of the hand. X-rays or MRI typically cannot identify the nerve injury or entrapment but can reveal other injuries avulsion.
Electrodiagnostic testing can identify the site of nerve entrapment and confirm the severty of any nerve damage.
Neuromusculoskeletal ultrasound can also identify injuries to the nerve and tendons.
In the short term, alternating ice and heat to the elbow can reduce inflammation and pain.
Anti-inflammatory medication can be prescribed.
Initially, stretching can increase the flexibility of the overlying tendons and improve the symptoms.
For a more severe or chronic problem, the athlets should see a professional, who will prescribe rehab specific to the athlete’s needs and goals.
If conservative treatment fails and pain or neurological symptoms become even more severe, surgery to decompress the nerve might be required.
The throwing athlete can return to action when the pain gas improved to the point at which a full pain-free throwing range of motion is achieved.
Most athletes can achieve this through exercise, stretching, and rehabilitation.
Rehabilitation should be guided by an experienced clinician.
A gradually progressing throwing program can preventreoccurrence of the injury.
If, however, surgery is performed, the athlete is looking at a longer road to recovery.
Some markers such as equal grip strength, wrist extensor strength, and finger extensor strength should be achieved before returning to throwing, golf, or racket sports.
