The most common cause of the syndrome is a pinched nerve branch (ramus superficialis nervi radialis) at its emerging point of the forearm between the brachioradialis and the extensor carpi radialis muscles. Treatment consists of locating the nerve’s entrapment point and releasing it from the confining area.
The complaints of Wartenberg’s syndrome are similar, if they are limited to pain and do not include numbness, to the appearance of tendovaginits stenosans De Quervain (congestion syndrome of the tendon of the abductor pollicis longus and extensor pollicis brevis). Therefore, some authors will require – even with clear diagnosis of this tendovaginitis- the inspection of the nerve’s exit site a few centimeters away, in order to avoid overlooking a potential additional cause of pain.
The health insurance companies cover the cost of the operation.
