Cervical laminoplasty is a motion-sparing technique used primarily for treating symptomatic spinal cord compression (myelopathy). It provides decompression of the spinal cord and cervical nerve roots by effectively increasing the cross-sectional area of the spinal canal. It is designed to preserve range of motion in the cervical spine and can be utilized for various causes of spinal canal narrowing.
The most commonly used technique is called the “open-door laminoplasty” which involves making a small cut on one side of the back of the spinal canal bones (lamina) and hinging or lifting the bone open. This increases the space available for the spinal cord allowing it to float backward, thus relieving its compression. The laminae that are hinged open are then stabilized in place with tiny plates and screws or sutures.
