Lumbar fusion surgery, also known as lumbar spinal fusion or spondylodesis, is a major surgical procedure that permanently joins two or more vertebrae in the lower back to eliminate motion between them. At Arthros Center in Patna, Bihar, we specialize in treating severe chronic lower back pain, spinal instability, spondylolisthesis, degenerative disc disease, and spinal deformities that have not responded to conservative treatments. The lumbar spine consists of five vertebrae (L1-L5) in the lower back. When these vertebrae or the discs between them become damaged due to injury, degeneration, or disease, they can cause severe pain, nerve compression, and functional disability. Lumbar fusion eliminates painful motion at the affected segment while maintaining overall spinal stability. Dr. Kumar and his specialized spine surgery team have successfully performed over 280 lumbar fusion procedures with a 92% patient satisfaction rate. Our approach combines modern surgical techniques including minimally invasive methods, advanced imaging guidance, and biologics to promote faster bone healing and optimal outcomes. **When is Lumbar Fusion Surgery Needed?** This surgery is typically recommended when conservative treatments such as physical therapy, medications, epidural injections, and lifestyle modifications have failed to provide adequate relief after 6-12 months. Common conditions requiring lumbar fusion include degenerative disc disease causing chronic mechanical back pain, spondylolisthesis (vertebral slippage) with nerve compression, spinal stenosis with instability, failed previous back surgery (revision fusion), traumatic fractures requiring stabilization, and scoliosis or kyphosis causing progressive deformity. **Types of Lumbar Fusion Techniques** At Arthros Center, we offer multiple fusion approaches tailored to each patient's specific condition: 1. **PLIF (Posterior Lumbar Interbody Fusion)**: Approach from the back with removal of the disc and insertion of bone graft cages between vertebrae. 2. **TLIF (Transforaminal Lumbar Interbody Fusion)**: One-sided approach that preserves more back muscles and ligaments - our most commonly performed technique. 3. **ALIF (Anterior Lumbar Interbody Fusion)**: Approach from the front of the abdomen, ideal for L5-S1 fusion with less muscle damage. 4. **MIS Fusion (Minimally Invasive)**: Uses smaller incisions and specialized retractors for faster recovery - available for select patients. **The Fusion Process** Spinal fusion uses bone graft material (your own bone, donor bone, or synthetic bone substitute) placed between vertebrae. Metal screws, rods, and cages hold the vertebrae in the correct position while the bone graft heals. Over 3-6 months, the bone grows and fuses the vertebrae into a single solid bone, eliminating motion at that segment. **Why Choose Arthros Center for Lumbar Fusion?** Our center offers specialized spine surgery expertise with fellowship-trained surgeons, advanced intraoperative navigation and imaging for precise screw placement, comprehensive pre-operative evaluation including psychological screening, multimodal pain management protocols for better recovery, dedicated spine physical therapy program, and affordable treatment under PMJAY and BSKY schemes. **Success Outcomes** Most patients experience significant pain reduction (60-80% improvement), improved quality of life and functional capacity, successful return to work and daily activities, and solid fusion with stable spine. Success rates are highest when proper patient selection criteria are followed. **Cost and Accessibility** Lumbar fusion surgery in India costs between ₹2,50,000-₹6,00,000 depending on the number of levels fused, technique used (open vs MIS), and implant type. At Arthros Center, we accept PMJAY (Ayushman Bharat) and BSKY coverage, making this life-changing surgery accessible to economically weaker sections of Bihar society.
