Peripheral nerve torsion is a rare cause of peripheral nerve palsy and its etiology is also unknown. It is usually misdiagnosed as compressive neuropathy or radiculopathy of spine though the treatment and clinical result are different from them. Authors present a case of radial nerve torsion. The symptom was same with a posterior interosseous nerve syndrome. However, the lesion is located not at forearm but at arm.
