What is pronator syndrome?
Pronator syndrome is a nerve disorder in the elbow and upper arm that causes pain, hand weakness and loss of feeling, often in the thumb and first three fingers. It involves compression of the median nerve in the forearm by muscles or ligament-like tissues. It may greatly decrease athletic performance in sports that require strong hand or wrist action.
How does pronator syndrome occur?
Pressure affects the median nerve at the forearm. It is caused by swollen, inflamed or scarred tissue ligament-like tissue or between muscles of the forearm. A virus may cause inflammation of the nerve.

How is pronator syndrome treated?
Non-operative treatment: Initial treatment consists of rest from the offending activity and medications and ice to help reduce inflammation. Discomfort often improves by shaking your hand or dangling your arm. Stretching and strengthening exercises of the muscles of the forearm and elbow are important. Referral to a physical therapist or an athletic trainer may be necessary for treatment.
Surgery may be necessary to free the pinched nerve. Surgery may be performed on an outpatient basis (you go home the same day), or you may be admitted for overnight stay. Surgery provides almost complete relief in most patients.
What are the complications of treatment?
Possible complications of non-operative treatment include:
Possible complications of operative treatment include:
When can you return to your sport/activity?
