cervical myelopathy

Etiology: - disc herniation - hypertrophy of the ligamentum flavus - ossification of the longitudinal ligament - spinal cord neoplasm - cervical spondylosis - congenital anomaly Clinical manifestations: - patients present with signs & symptoms of cervical spinal cord dysfunction with or without cervical radiculopathy - neck pain, shoulder pain &/or pain in upper limbs may occur - loss of manual dexterity - gait & balance disturbances - increase tone & heaviness in lower extremities - Romberg's sign, Babinski's sign - Lhermitte sign may be present (electric shock sensation with neck flexion) - sensory loss in the hands or feet - arm or hand weakness - fecal or urinary frequency, urinary urgency, or urinary hesitancy - upper-motor-neuron signs [5] Radiology: - magnetic resonance imaging (MRI) of the cervical spine Management: - surgical decompression improves neurologic function in some patients & prevents worsening in others - age is an independent predictor of surgical outcome - adults > 65 years of age do not have as much improvement in functional status after surgery as younger patients, but report similar quality-of-life improvements [3]
