Spinal fusion surgery is performed to treat conditions like herniated discs, spinal stenosis, spondylolisthesis, degenerative disc disease, and scoliosis that cause chronic pain, numbness, weakness, or instability. Surgery is considered when conservative treatments fail, and diagnostic imaging like MRI or CT scans confirms significant spinal issues. The procedure fuses two or more vertebrae to stabilize the spine and reduce pain, with success rates generally between 70–90%. Qualified neurosurgeons or orthopedic spine surgeons at reputable hospitals with advanced spine centers ensure the best outcomes. In India, the cost ranges from ₹1,20,000 to ₹8,50,000 depending on the procedure and hospital. Recovery involves hospital stay for a few days, gradual resumption of activities, physical therapy to restore strength and mobility, avoiding heavy lifting, and engaging in low-impact exercises for long-term spinal health.
