About Pronator Syndrome
Pronator syndrome is caused by a compression of the proximal median nerve. This condition is commonly misdiagnosed because it is difficult to detect through testing and most physicians and/or neurologists are not aware of it, nor how to diagnose it.
Pronator syndrome mimics the symptoms of carpal tunnel syndrome and this is why it is often missed or confused. It’s the same nerve compressed, but at a more proximal location. Patients experience a lot of forearm tenderness.
If your physician does EMG/NCV testing and the results are normal, ask them if they tested for pronator syndrome. Some clues on the EMG/NCV test are:
- A normal nerve conduction velocity test with fibrillations in abductor pollicis brevis muscle.
- Fibrillation potentials in non anterior interosseus innervated muscles: palmaris longus, flexor carpi radials or flexor digitorum superficialis muscle.
About the Endoscopic Assisted Pronator Release
The endoscopic assisted pronator release is a minimally-invasive surgical procedure that decompresses the proximal nerve with the aid of an endoscope. Much like the endoscopic carpal tunnel release, this procedure usually requires no stitches. Watch the video below to watch the feed from an endoscope while this surgery is performed.
