What is it?
Cervical laminoplasy is an operation that involves relieving pressure placed on the nerve roots and/or spinal cord by a herniated disc or bone spurs. For patients with painfully restricted spinal canals in their necks, the cervical laminoplasty procedure immediately relieves pressure by creating more space for the spinal cord and roots. The technique is often referred to as an “open door laminoplasty,” because the back of the vertebrae is made to swing open like a door.
What is done during a cervical laminoplasty?
An understanding of what cervical laminoplasty involves will help you to approach your operation and recovery with confidence. The operation is performed with you lying prone (on his/her stomach). An incision is made to the back of the neck and a groove is cut down one side of the cervical vertebrae creating a hinge. The other side of the vertebrae is cut all the way through and the tips of the spinous processes are removed to create room for the bones to pull open like a door.
The back of each vertebrae is bent open like a door on its hinge, taking pressure off the spinal cord and nerve roots and mall wedges made of bone are placed in the opened space of the door. The door of the vertebrae swings shut, and the wedges stop it from closing all the way. The spinal cord and the nerve roots rest comfortably behind the door.
