Cervical Laminoplasty
This procedure widens the spinal canal by removing the lamina (a bony plate that covers the spinal canal) and then “swinging” the freed flap of bone open thus relieving the pressure on the spinal cord to reduce pain and numbness. The bone flap is then propped open using small wedges or pieces of bone so that the newly enlarged spinal canal will remain in place. Most patients remain in the hospital for a few days following laminoplasty. Activity levels, pain management and care of the incision will be thoroughly discussed with the patient prior to and after the procedure.
Figure: This is a patient with multilevel cervical stenosis and spinal cord compression as demonstrated on the MRI. He underwent a “laminoplasty” to create more space around the spinal cord, thus relieving the pressure off and “unpinching” the spinal cord. The intraoperative radiograph on the right shows the small laminoplasty plates which are holding open the lamina and creating the space around the spinal cord.
