Microdiscectomy and laminectomy are both surgical procedures used to treat conditions that affect the spinal disc, but they have distinct differences in terms of their approach and goals.
Microdiscectomy is a minimally invasive procedure that focuses on removing a portion of the herniated disc that is pressing on the spinal nerve root. This procedure is typically performed through a small incision, using a microscope to guide the surgeon in accurately removing the affected disc material. By targeting the specific source of nerve compression, microdiscectomy aims to relieve pain and improve overall function without compromising the stability of the spine.
On the other hand, laminectomy involves removing a portion of the lamina, which is the bony arch that protects the spinal cord. This procedure is done to create more space within the spinal canal, allowing for decompression of the nerves and relieving pressure on the spinal cord. Laminectomy is often performed in cases of spinal stenosis, where there is a narrowing of the spinal canal due to conditions such as arthritis or bone spurs.
In summary, while both microdiscectomy and laminectomy target spinal conditions, they differ in their specific surgical approach and the goals they aim to achieve. Microdiscectomy focuses on removing the herniated disc material, while laminectomy aims to create more space within the spinal canal to alleviate nerve compression.
Why would a surgeon recommend a laminectomy?
Laminectomy may be done to ease pressure on the spinal nerves, treat a disk problem, or remove a tumor from the spine. One common reason for having a laminectomy is a herniated disk in the spine. A disk may be displaced or damaged because of injury or wear and tear.
Is a laminectomy always done with a discectomy?
Minimally invasive surgeries typically use smaller incisions than those used for open procedures. If laminectomy is being performed as part of surgical treatment for a herniated disk, the surgeon also removes the herniated portion of the disk and any pieces that have broken loose (diskectomy).
Is a laminectomy a major surgery?
This is considered a major surgery and the last resort if conservative methods of treatment doesn’t work.
Is laminectomy and Microdiscectomy the same?
A laminectomy involves the removal of all or part of the vertebral bone (lamina). A microdiscectomy involves the removal of a portion of the intervertebral disc, usually the herniated or protruding portion compressing the traversing spinal nerve root.
