Lumbar Fusion
A lumbar fusion is a surgical procedure used to stabilize the spine by permanently joining two or more vertebrae in the lower back. This is done to eliminate painful motion between them and to treat conditions such as:
Degenerative disc disease
Spondylolisthesis
Spinal instability
Severe disc herniation
Recurrent spinal stenosis
During the procedure, the surgeon removes the damaged disc or tissue between the vertebrae and inserts bone grafts, sometimes along with metal rods, screws, or cages, to help the vertebrae grow together into one solid bone over time.
The goal of lumbar fusion is to reduce pain, improve stability, and prevent further degeneration
Frequently Asked Questions About Lumbar Fusion Surgery
What is lumbar fusion surgery?
Lumbar fusion is a surgical procedure that permanently joins two or more vertebrae in the lower back (lumbar spine) to eliminate painful motion between them. The surgeon removes the damaged disc between the vertebrae, inserts bone graft material to promote bone growth, and typically uses metal screws and rods to hold the vertebrae in place while they fuse together. At Awake Spinal Fusion, Dr. Alok Sharan performs lumbar fusion using minimally invasive techniques under regional anesthesia, meaning patients stay awake during the procedure. This approach avoids the risks of general anesthesia, requires smaller incisions, causes less muscle damage, and enables faster recovery. Lumbar fusion effectively treats conditions including spondylolisthesis, degenerative disc disease, spinal instability, and recurrent disc herniations that have not responded to conservative treatment.
How long does it take to recover from lumbar fusion?
Recovery from lumbar fusion performed with the awake spine technique at Awake Spinal Fusion is significantly faster than traditional approaches. Most patients are discharged the same day or the next morning, compared to two to four days with conventional lumbar fusion. Walking typically begins within hours of surgery. Patients can resume light activities and desk work within two to three weeks. Driving is usually permitted at two to four weeks, depending on pain levels and medication use. Return to more physically demanding activities generally takes six to twelve weeks. Complete bone fusion between the vertebrae requires approximately six to twelve months, during which Dr. Sharan monitors progress through follow-up imaging and clinical examinations. A personalized rehabilitation program including physical therapy exercises helps optimize recovery outcomes.
Can lumbar fusion be done while awake?
Yes. Dr. Alok Sharan is a pioneer of performing lumbar fusion under regional (spinal) anesthesia, allowing patients to remain conscious throughout the procedure. The regional anesthesia completely numbs the lower body from the waist down while the patient remains comfortable and aware. Dr. Sharan has published multiple peer-reviewed studies demonstrating that awake lumbar fusion achieves clinical outcomes equivalent to traditional general anesthesia approaches while offering significant advantages. These advantages include elimination of intubation risks, reduced postoperative nausea and vomiting, decreased opioid requirements, faster return to normal diet, and same-day or next-day discharge. The awake technique also allows the surgeon to communicate with the patient during the procedure, providing an additional safety check for nerve function. This approach is suitable for most patients requiring lumbar fusion surgery.
What conditions require lumbar fusion?
Lumbar fusion may be recommended for several conditions that cause chronic lower back pain or leg symptoms when conservative treatments have failed. The most common indications include spondylolisthesis, where one vertebra slips forward over the one below it; degenerative disc disease, where deteriorated discs cause chronic pain and instability; spinal stenosis with instability, where narrowing of the spinal canal occurs alongside abnormal vertebral movement; recurrent disc herniations, where a disc re-herniates after previous surgical treatment; and spinal fractures that create instability. Lumbar fusion is typically considered after patients have tried non-surgical treatments for at least six to twelve weeks without adequate relief. Dr. Sharan performs a thorough evaluation including physical examination, MRI review, and sometimes diagnostic injections to confirm the pain source before recommending fusion surgery.
What is the success rate of lumbar fusion surgery?
Lumbar fusion surgery has a well-documented success rate of approximately 70 to 90 percent for achieving solid fusion and meaningful pain relief, depending on the specific condition being treated and the surgical technique used. Patients undergoing awake lumbar fusion at Awake Spinal Fusion with Dr. Alok Sharan benefit from the advantages of minimally invasive technique combined with regional anesthesia. Published studies on the awake spine approach demonstrate high patient satisfaction scores, reduced complication rates, and faster functional recovery compared to traditional open fusion under general anesthesia. Success rates are highest for patients with clearly identified pain generators, such as spondylolisthesis or single-level degenerative disc disease. Dr. Sharan uses advanced imaging and diagnostic techniques to identify ideal surgical candidates and optimize outcomes for each patient.
