Motion Preserving Surgery in Two Cases of Brown-Sequard Syndrome Caused by Herniated Cervical Discs

We described two cases of Brown-Sequard syndrome caused by cervical disc herniation that were treated by cervical artificial disc replacement. Two patients presented Brown-Sequard syndrome. Computed tomography scanning and magnetic resonance imaging showed a massive soft disc herniation compressing the spinal cord. We performed a total discectomy to remove the ruptured disc particle and replace it with an artificial disc. The neurologic symptoms of two patients were resolved after the surgery. We suggest that cervical arthroplasty can also be used to treat more severe forms of cervical myelopathy such as Brown-Sequard syndrome.
