The lower back endures a lot of wear and tear throughout our lives. One common culprit for pain in this region is a herniated disc. This occurs when the soft inner core of an intervertebral disc, the spongy cushions between your vertebrae, bulges or leaks out through a tear in its tougher exterior. If this protrusion pinches a spinal nerve, it can cause a cascade of pain, numbness, and weakness, often radiating down the leg in a condition called sciatica.

In such cases, a minimally invasive surgical procedure called a micro lumbar discectomy can offer significant relief. Special spine orthopaedic implants are used during the procedure. Let's delve deeper into this surgical approach.

What is Herniated Disc and Nerve Compression?

The lumbar spine refers to the lower five vertebrae in your back. Each vertebra connects to the one above and below through facet joints, with intervertebral discs in between. These discs serve as shock absorbers. Hence, provides flexibility to the spine. The inner core (nucleus pulposus) is a gel-like substance, while the outer shell (annulus fibrosus) is a ring of strong ligaments.

A herniated disc happens when the annulus tears, allowing the nucleus to push through. If this material compresses a spinal nerve root branching out from the spinal cord, it triggers a range of symptoms like:

• A sharp, burning pain (Sciatic pain) radiating down the buttock and leg along the sciatic nerve path

• Weakness or numbness in the leg

• Tingling or pins and needles sensation

• Difficulty walking or standing for extended periods

What if Conservative Measures Fall Short?

Most herniated disc cases can be managed conservatively with a combination of rest, physical therapy, anti-inflammatory medication, and pain relievers. However, if these measures fail to provide relief after a reasonable trial period, or if the neurological symptoms are severe and progressive, a micro lumbar discectomy might be recommended by your doctor.

What is Micro Lumbar Discectomy?

A micro lumbar discectomy is a surgical procedure designed to remove the herniated disc material compressing the nerve. Compared to a traditional open discectomy that uses a larger incision and more extensive muscle dissection, the microdiscectomy boasts several advantages:

Smaller incision: The surgeon makes a small incision, typically 1-2 inches long, minimizing muscle disruption.

Enhanced visualization: A microscope or high-powered loupes magnify the surgical field, allowing for greater precision.

Faster recovery: Due to the minimally invasive nature, patients generally experience shorter hospital stays and quicker return to daily activities.

Reduced blood loss: Smaller incisions translate to less blood loss during surgery.

What is the Procedure of Micro Lumbar Discectomy?

A micro lumbar discectomy is typically performed under general anesthesia. Here's how surgical process may go:

Preparation: The surgical area on your back is prepped and sterilized.

Incision and Access: A small incision is made, and the surgeon carefully separates muscles using special techniques to reach the affected disc space.

Visualizing the Disc: A microscope or loupes is used for magnified visualization of the surgical field.

Removing the Herniation: Using specialized tools, the surgeon removes only the portion of the disc material that's pressing on the nerve. The healthy disc tissue remains intact.

Closure: The surgical site is meticulously closed with sutures or staples.

How Recovery Occur After Surgery?

Following surgery, you'll likely spend a night or two in the hospital for monitoring. Pain medication is administered to manage discomfort. Physical therapy plays a crucial role in recovery, helping to strengthen core muscles and improve spinal flexibility to prevent future issues. Most patients can return to work and normal activities within a few weeks, depending on their occupation and the severity of their pre-operative condition.
