Microlumbar Discectomy in Thailand

What is Microlumbar Discectomy?
Microlumbar Discectomy is a minimally invasive surgical procedure in which a compressed nerve root in the lower back due to a herniated inter-vertebral disk is decompressed. Decompression of the nerve root relieves the back and leg pain.

How is Microlumbar Discectomy Performed?
A small incision of approximately one inch is made on the patient’s low back, above the compressed nerve root. An operative microscope is used to remove a crescent shaped part of the bone from the spine, which then discloses the compressed nerve root and herniated inter-vertebral disk. Then, the nerve root is decompressed by removing the disc. The disc nucleus that is degenerated is removed with a curette from the central disc space. The incision is then closed with dissolvable sutures.

How to Prepare for the Surgery?

• The patient should inform the doctor about any ailments, medical conditions and medication that the patient may be taking.
• The patient should not smoke for several days before the surgery.
• Two weeks prior to the surgery, the doctor may stop certain medication that the patient may be taking.
• The patient is required to do an MRI or CT scan before a microlumbar discectomy.
