Micro Discectomy Surgery In India

In a microdiscectomy or microdecompression spine surgery, a small portion of the bone over the nerve root and/or disc material from under the nerve root is removed to relieve neural impingement and provide more room for the nerve to heal.

A microdiscectomy is typically performed for a herniated lumbar disc and is actually more effective for treating leg pain (also known as radiculopathy) than lower back pain.

How Microdiscectomy Surgery Is Performed ?

A microdiscectomy is performed through a small (1 inch to 1 1/2 inch) incision in the midline of the low back.

• First, the back muscles (erector spinae) are lifted off the bony arch (lamina) of the spine. Since these back muscles run vertically, they can be moved out of the way rather than cut.
• The surgeon is then able to enter the spine by removing a membrane over the nerve roots (ligamentum flavum), and uses either operating glasses (loupes) or an operating microscope to visualize the nerve root.
• Often, a small portion of the inside facet joint is removed both to facilitate access to the nerve root and to relieve pressure over the nerve.
• The nerve root is then gently moved to the side and the disc material is removed from under the nerve root.

Importantly, since almost all of the joints, ligaments and muscles are left intact, a microdiscectomy does not change the mechanical structure of the patient’s lower spine (lumbar spine).

Why It Is Done ?

When surgery is used to treat a herniated disc, it is done to decrease pain and allow for more normal movement and function.

Surgery Is Considered An Emergency If You Have Cauda Equina Syndrome. Signs Include : –

• New loss of bowel or bladder control.
• New weakness in the legs (usually both legs).
• New numbness or tingling in the buttocks, genital area, or legs (usually both legs).

Surgery may be considered if tests show that your symptoms are due to a herniated disc and your doctor thinks surgery may help relieve the symptoms.

In Deciding Whether To Have Surgery, You And Your Doctor Will Consider Factors Such As : –

• A history of persistent leg pain, weakness, and limitation of daily activities that has not gotten better with at least 4 weeks of nonsurgical treatment.
• Results of a physical examination that show you have weakness, loss of motion, or abnormal sensation (feeling) that is likely to get better after surgery.
• Diagnostic testing, such as magnetic resonance imaging (MRI), computed tomography (CT), or myelogram, that indicates your herniated disc would respond to surgery.

Risks & complications

Complications are infrequent and usually minor. However, as with any surgery, there are risks, including the possibility of : –

• Nerve root damage leading to a sensation of numbness, tingling or weakness in the legs
• Tears to the protective coating around the nerves and spinal chord
• Re-herniation of the same disc
• Pain that persists or worsens after surgery
• Reaction to the anesthesia

Risks can be reduced by following the surgeon’s instructions before and after surgery.

How Is It Done ?

Microdiscectomy may be performed under a local anesthetic combined with intravenous sedation, which means you would be awake during the surgery. A general anesthetic may also be used. A small incision (about two inches) is made between the bones of the vertebrae on the back. The surgeon will then move the back muscles to the side. A flexible tube containing surgical implements and a high powered telescope is used to perform surgery and guide the doctor as herniated disc tissue and fragments are removed.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_message message_box_color=”pink”]
