Posterior column dysfunction in cervical spondylotic myelopathy.
Five patients had cervical spondylotic myelopathy (CSM) with severe prorioceptive sensory loss in the upper and lower limbs. Despite an advanced age, each recovered considerable function following cervical laminectomy, in follow-up periods of 10 to 40 months. The role of newer methods of investigation including CT scanning, somatosensory evoked responses and nuclear magnetic resonance is discussed. The cause of the proprioceptive sensory loss in these patients cannot be definitively determined, but various ischemic and compressive lesions are discussed as possible pathogenetic mechanisms.
