A cervical laminectomy is a specialized surgical procedure primarily designed to alleviate pressure on the spinal cord in the neck region. But what does this procedure entail, and why is it necessary?
The cervical spine, situated in the neck, is susceptible to a condition known as cervical spinal stenosis. This occurs when there is a narrowing of the spinal canal, causing undue pressure on the spinal cord, leading to pain, muscle weakness, difficulty in walking, and even the loss of bowel or bladder control. One effective way to address this issue is through a cervical laminectomy.
The procedure begins with the patient under general anesthesia. An incision is made down the middle of the back of the neck, granting the surgeon access to the cervical spine. From here, the surgeon removes the lamina, a bony structure of the vertebrae. The primary goal is to create space and relieve the pressure on the spinal cord. This is achieved by removing specific sections of the bone that cover the spinal canal.
While a cervical laminectomy removes the entire lamina, there are variations like the laminotomy where only a portion of the lamina is removed. Both these procedures target the bone or the ligaments compressing the spinal nerve to provide relief.
It’s also worth noting the difference between a cervical laminectomy and a cervical laminoplasty. The latter reshapes the bone rather than removing it. It is another specialized procedure that focuses on relieving spinal cord pressure but takes a different approach.
In some instances, post the cervical laminectomy, the spine’s stability might be compromised. To counter this, the remaining spinal bones are fused back together using titanium metal rods and screws. This ensures stability and integrity of the spine after the procedure.
In essence, a cervical laminectomy is a decompression surgery designed to offer relief from the symptoms of cervical spinal stenosis or related spinal issues. It’s an effective solution especially when the spinal cord is compressed by the ligamentum flavum, a ligament inside the roof of the spinal canal.
