Case Review #5: 46 year old female treated with a Prestige Disc

  1. 1. Case Review:Prestige Artificial Disc at C5/6Robert S Pashman, MDScoliosis and Spinal Deformity Surgerywww.eSpine.com
  2. 2. Patient History46 year old femalePresented with neck pain, and numbness in both hands.C5-6 disc herniation with hard soft disc which on multipleMRIs show a subtle gliosa in the spinal cord, effacementof the spinal cord at this level.The patient has evidence of myeloradiculopathy withbilateral hand numbness, neural foraminal stenosis also.The patient has mild degenerative disc disease at C6-7.
  3. 3. Pre-op X-rays
  4. 4. Flexion/Extension X-rays
  5. 5. Indications for SurgeryThe indications for disk replacement include degeneration at C6-7,which is not symptomatic at this point, with disk herniation at C5-6,although the adjacent segment protective aspects of TDR versusfusion are debatable. The patient is an ideal candidate in that shedoes have subjacent early degeneration, and the use of an artificialdisk replacement might preclude her from having accelerateddegeneration in the subjacent space. Clearly, she needs surgerybecause she has evidence of myeloradiculopathy with pain in theleft arm, numbness which is ongoing, and has gliosis in her cordwith significant narrowing at this level.Massive disc herniation C5-6 with neural foraminal stenosis.Severe cord compression with soft disc causing gliosis.Mild radiculopathy.Several disc degeneration C6-7.Failed conservative therapy.
  6. 6. Surgical Strategy1. Radical discectomy, C5-6, with removal of disc herniation, posterior annulus and posterior longitudinal ligament.2. Subtotal vertebrectomy with one-third vertebrectomy C6 vertebra for removal of massive anterior osteophyte, posterior uncal vertebral osteophytes, superior and inferior in to the foramina.3. Prestige cervical total disc replacement measuring 7 x 16 mm for replacement of herniated disc, C5-6.4. Intraoperative SSEPs.5. Intraoperative fluoro.

  8. 8. Pre-Op/Post-op Comparison The patient’s natural cervical lordosis has been restored. The patient is doing well post- operatively.
