Posterior Cervical Laminoplasty is a surgical procedure performed to release pressure over the spinal cord and nerve roots in the cervical spine (neck). A posterior cervical laminoplasty can be beneficial in treating cervical spinal stenosis, cervical herniated disc, cervical radiculopathy, degenerative disc disease, tumor, and infection.
The procedure is performed under general anesthesia and X-ray or fluoroscopic guidance. The lamina is completely cut on one side and partially cut on the other which creates a hinge on one side of the lamina, and a small opening on the other. The tips of the spinous processes, projections of bone which can be felt as you rub your fingers along the back of your spine, are removed to create room for removal of the lamina. This releases the pressure over the spinal cord and the nerves. A wedge, made out of bone or metal, is used to hold the lamina in position during the healing process. An intraoperative X-ray is taken to check the positioning of the wedge.
A cervical collar is recommended to offer stability and support during the healing process. You can begin doing physical therapy as directed by your doctor.
The possible risks associated with posterior cervical laminoplasty surgery may include infection, bleeding, problems with anesthesia, and nerve injury.
