Microdiscectomy

What is a microdiscectomy in the lumbar spine?

A microdiscectomy is a minimally invasive surgical procedure to relieve sciatica and other symptoms caused by a herniated disc pressing on a nerve root in the lower back. Due to age or injury, the outer disc wall may dry out, causing the soft part to bulge, leading to pain, tingling, or weakness, especially down the leg. The surgery to correct the condition involves removing all or a small portion of the disc that is bulging out and compressing the nerve. The minimally invasive procedure is the gold standard to treat most lumbar spine disc herniations. Doctor Andre M. Samuel, orthopedic spine specialist, treats patients in the Clear Lake, Houston, Sugar Land, TX area who may need a minimally invasive microdiscectomy in the lower back.

Why would I need a lumbar microdiscectomy?

A lumbar microdiscectomy may be recommended if the symptoms from a herniated disc have lasted longer than six weeks, impact your ability to perform daily activities or affect your quality of life. Those with chronic sciatica – sharp shooting pain down one leg, could be a candidate for the procedure if non-surgical treatments have offered no relief. Numbness, tingling, or weakness in your legs or feet may also indicate the need for a microdiscectomy. Since a herniated disc can lead to the loss of bowel or bladder control (cauda equina syndrome), Dr. Samuel may recommend surgical intervention to avoid these serious side effects.

How is minimally invasive lumbar microdiscectomy done?

A microdiscectomy is an outpatient procedure performed under general anesthesia. The patient typically goes home the same day. Dr. Samuel makes a small 2cm incision over the affected area of the spine and inserts a small tube between the vertebrae to reach the herniated disc. He will then use tiny surgical instruments to remove the part of the disc causing the pain. The incision is closed with either sutures or staples. Unlike traditional surgery, this method is less invasive and offers a quicker recovery. As with any surgery, there are risks – depending on a patient’s age and general health. Dr. Samuel and his team discuss the risks and benefits with each patient before surgery.

How long does it take to recover from a minimally invasive lumbar microdiscectomy?

The recovery from a minimally invasive lumbar microdiscectomy varies from patient to patient. Typically, pain associated with pressure from a herniated disc stops immediately after surgery, with a full recovery taking about six weeks. Dr. Samuel sends each patient home with instructions to avoid heavy lifting and refrain from exercise for up to four weeks. Physical therapy may also help strengthen your back after the microdiscectomy. A back brace may also help stabilize the back after the procedure.

While pain from the herniated disc goes away quickly, pain from the actual procedure can linger. Over-the-counter medications such as NSAIDs and Tylenol can help ease the pain. The good news? Most patients return to work within a week or so of the surgery.
