  • Abstract
  • Look Inside

 We experienced two cases of cervical myelopathy caused by atlas hypoplasia with idiopathic atlanto-axial subluxation. Case 1 was a female, 50 years of old. She presented herself in our clinic with chief complaints included numbness in limbs and dysbasia. Neurologically, exalted tendon reflex in limbs, subtlety dyskinesia of hand and spastic walking were observed. JOA score was 13 points. Case 2 was a male, 75 years of old. He presented himself in our clinic with a chief complaint of weakness of lower limbs. Subtlety dyskinesia of hand, abasia and dysuria were observed and JOA score was 6 points. Lateral views of plain x-ray film and CT-myelograms of these two cases showed that posterior arch on atlas encroached upon vertebral canal and occipitofrontal diameter of atratic vent was narrow, so we gave them diagnosis of hypoplasia. MRI showed significant stenosis, and T2-weighted image showed gross focal constriction of in pulpa. Posterior fixation of C0-2-3 was needed for C1 laminectomy because of cervical myelopathy with idiopathic atlanto-axial subluxation.
