Median nerve mononeuropathy in spondylotic cervical myelopathy : double crush syndrome?

We studied the association between spondylotic cervical myelopathy (SCM) and median nerve mononeuropathy (MNM) and examined the validity of the double-crush hypothesis. Sixty consecutive patients with clinically overt spondylotic cervical myelopathy were examined by means of nerve conduction studies...

Description
Summary:We studied the association between spondylotic cervical myelopathy (SCM) and median nerve mononeuropathy (MNM) and examined the validity of the double-crush hypothesis. Sixty consecutive patients with clinically overt spondylotic cervical myelopathy were examined by means of nerve conduction studies, electromyography, and median nerve somatosensory evoked potentials; the frequency of the electrophysiological signs of focal MNM at the wrist was compared with that of a control group comprising 100 sex- and age-matched patients. Electrophysiological signs of MNM were found in 20 myelopathic patients (33%) in comparison with an 11% prevalence in the control group (P
