Radial nerve syndrome is a condition in which the radial nerve becomes compressed in a small passage on the outside (lateral aspect) of the elbow. Its symptoms are very similar to tennis elbow and it can be hard to differentiate between the two conditions. The radial nerve is vulnerable to compression as it passes beneath the supinator muscle. This muscle is responsible for turning the right hand clockwise for example when closing a jar or tightening a screw. Overuse of the supinator muscle can therefore cause compression of the radial nerve. The nerve can also be stretched and irritated by repeated forceful pushing and pulling, gripping, pinching and bending of the wrist.
Symptoms
- The symptoms are similar to those of tennis elbow
- Pain on the outside of the elbow. The pain is typically further towards the wrist (about 4cm away from elbow) than with tennis elbow.
- Weakness of the wrist, especially bending wrist backwards (wrist extension).
- Reduced sensation around outside aspect of the wrist is a rare symptom
- Pain aggravated by
- Bending wrist backwards
- Turning palm upwards (supinating wrist).
- Holding something with stiff wrist or straightend elbow
What you can do
- Rest and avoidance of aggravating activites
- Wrist extension
- Supinating wrist
- Pushing/pulling heavy objects
- Use of adjuncts to take load of elbow
- Wrist strap
- Wrist splint
- Elbow pad
What we can do
- Massage and stretching to reduce tension in the supinator muscle
- Prescription of stretching and strengthening exercises
