A laminoplasty, similar to a laminectomy, is often performed on patients suffering from spinal stenosis in the neck (narrowing of the cervical spinal canal). It is also referred to as an "open-door laminoplasty." A laminoplasty creates more space for the spinal cord and roots. The actual procedure involves cutting a “hinge” into one side of the lamina and swinging it open like a door. It relieves pressure on the spinal cord by increasing the diameter of the spinal canal and room for the spinal cord. The surgery approach is through the back of the neck. This procedure creates excellent spinal canal decompression without the instability that may be created by multiple level cervical laminectomies.
An incision is made on the back of the neck. 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. 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. Small 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.
A laminoplasty is a procedure that reaches the cervical spine from the back of the neck, which is then reconstructed to make more room for the spinal canal.
For patients with painfully restricted spinal canals in their necks, this 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," since the back of the vertebrae is made to swing open like a door.
