Minimally Invasive Lumbar Discectomy Dallas

What is Minimally Invasive Lumbar Discectomy? 

Lumbar discectomy is a spinal surgery that involves the removal of the damaged intervertebral disc(s), specifically the herniated nucleus pulposus, to relieve pressure on the spinal nerves (decompression) in the lumbar (lower back) region, which forms the lower portion of the spine and comprises five vertebrae (L1-L5). A minimally invasive technique is implemented by an experienced spine specialist to perform the surgery, reducing blood loss and damage to surrounding muscles and adjacent nerves compared to traditional open back surgery.

Indications for Minimally Invasive Lumbar Discectomy

This minimally invasive discectomy procedure is a form of minimally invasive spinal surgery that is indicated in cases of severe nerve root compression due to a ruptured disc. Symptoms of nerve impingement include lower back pain or radiating pain into the hips, buttocks, or legs, numbness or tingling sensation, and muscle weakness in the back and lower extremities.

Minimally Invasive Lumbar Discectomy Procedure

• The procedure will be performed with you lying on your stomach under general anesthesia. A small incision, less than 1 inch, is made over your lower back, and your spine doctor gently separates the soft tissues and muscles to access the affected disc, ensuring minimal disruption to surrounding tissues.
• A tubular retractor can be inserted to produce a portal through which your minimally invasive surgeon can perform the minimally invasive surgery with precision.
• Through the tubular retractor, a portion of the lamina, the bony vertebral component that covers the posterior wall of the spinal canal, is carefully removed to expose the compressed area of the spinal cord or nerve roots affected by spinal nerve compression.
• Removal of the lamina releases the source of compression from the herniated disc or bone spurs. The complete procedure is known as decompression. After the surgery is performed, the incision is closed, leaving behind a minimal scar, and this typically results in a shorter hospital stay.

Postoperative Care following Minimally Invasive Discectomy

The post-surgical hospitalization includes the rehabilitation program. If required, your spine specialist may prescribe pain medications or a brace and follow-up physical therapy upon discharge.

The recovery period depends on your body’s healing capacity. The period of your rest or inactivity depends on a few factors, such as the type of surgical procedure and the approach used to access your spine, the size of the incision, the presence of any complications, and whether additional procedures like spinal fusion were performed. Return to work or normal activity depends on the type of work or activity you plan to perform, and most patients are advised to avoid heavy lifting and strenuous activities for several weeks. Usually, 3 to 6 weeks is the ideal time for healing.

Strictly adhere to the postoperative instructions suggested by your spine surgeon to promote healing and reduce the possibility of postoperative complications, including infection and severe pain.

Advantages of Minimally Invasive Lumbar Discectomy Dallas

Some of the benefits of this minimally invasive discectomy procedure include:

• Very small incisions are made, typically less than 1 inch, reducing tissue disruption
• Minimally invasive surgeries can be performed in less time
• Minimal damage to the surrounding structures, including muscles and nerves, is made
• Recovery time is shorter with fewer post-surgical complications
• There is a lower rate of infection
• You will have a greater range of motion with less postoperative pain
