Radial tunnel syndrome occurs when the radial nerve is entrapped in the supinator muscles, which are the muscles helping to rotate the forearm. This condition is common with people who play racket sports like tennis and with spin bowlers.
An orthopedic doctor can correctly diagnose radial tunnel syndrome by conducting a thorough physical exam. Images are usually taken to rule out other possible problems.
Stretching, technique modification, physical therapy, and neoprene bracing are common treatment methods. More severe symptoms may require surgery to reduce pressure on the affected nerve.
