Spinal decompression involves surgical procedures that relieve pressure on the spinal cord or nerve roots. These techniques address nerve compression, which can cause pain, numbness, or weakness. Understanding the different types of spinal decompression surgery is a helpful step for anyone exploring treatment options. Here is more information about techniques that may help:
Discectomy Technique
A discectomy is a surgical procedure to remove damaged portions of a herniated disc in the spine. Neurosurgeons perform this operation to relieve pressure on nearby nerves, and it helps to treat radiating nerve pain. The primary goal is to address the source of nerve compression while preserving as much of the healthy disc as possible.
When a herniated disc pinches a nerve, it can cause significant discomfort, so the surgeon carefully removes the disc. The procedure may be performed as an open surgery or through minimally invasive techniques. A successful discectomy allows the affected nerve to heal and function properly again.
The specific approach depends on the location and severity of the herniation. Minimally invasive microdiscectomy uses a small incision and special tools, which typically results in a quicker recovery period. After the procedure, physical therapy may be recommended to strengthen back muscles and support long-term spinal health, promoting better recovery.
Corpectomy Technique
A corpectomy involves the removal of a vertebral body along with the adjacent discs to decompress the spinal cord. This spinal decompression procedure is typically reserved for cases where spinal cord compression is caused by multilevel stenosis or bone spurs that are not treatable with less extensive operations. Surgeons access the spine from the front of the body to perform the removal.
Following the removal of the vertebra and discs, the surgeon must stabilize the spine. A bone graft is inserted into the empty space, and metal plates and screws are often used to hold the vertebrae together while they fuse. This fusion process creates a solid, stable column of bone, and it provides strong, durable support.
Laminectomy Procedure
A laminectomy is a surgical procedure that creates space by removing the lamina, which is the back part of a vertebra that covers the spinal canal. This removal enlarges the spinal canal to relieve pressure on the spinal cord or nerves. It is performed to address lumbar spinal stenosis. A laminectomy may be part of a larger surgery to treat a herniated disc, and it can help relieve nerve pressure.
Laminotomy Procedure
A laminotomy is a less invasive procedure because it creates a small opening in the lamina without removing it entirely. The surgeon makes a hole in the lamina just large enough to relieve pressure on a specific nerve root, so the natural bony structure of the spine remains mostly intact. This procedure is suitable for addressing more localized compression and offers several benefits.
- Preserves spinal stability
- Shorter recovery time
- Reduced postoperative pain

Spinal decompression procedures offer a way to relieve pressure on spinal nerves and address the underlying causes of certain types of back and neck pain. The specific technique used will depend on your individual diagnosis and the location of the nerve compression. If you have persistent symptoms, consult a neurosurgeon to find the best course of action for your spinal health.
