Description

What is PLIF Spinal Fusion? Posterior Lumbar Interbody Fusion (PLIF) is a spinal fusion surgery performed through a posterior (back) approach to stabilize the lumbar spine and relieve nerve compression. In this procedure, the damaged intervertebral disc is removed and replaced with an interbody cage or bone graft, while pedicle screws and rods are inserted to stabilize the vertebrae. PLIF helps restore disc height, spinal alignment, and stability, while also relieving pressure on compressed spinal nerves. It is commonly used to treat degenerative spine disorders and spinal instability. SEO Keywords: PLIF Surgery, Posterior Lumbar Interbody Fusion, Lumbar Spinal Fusion Surgery, Spine Stabilization Conditions Treated with PLIF Surgery PLIF spinal fusion may be recommended for patients with: • Spondylolisthesis (vertebral slip) • Degenerative disc disease with instability • Severe lumbar disc degeneration • Lumbar canal stenosis with instability • Recurrent lumbar disc herniation The goal of PLIF surgery is to decompress the nerves and stabilize the affected spinal segment. During PLIF surgery: 1. A surgical approach is made through the posterior (back) part of the spine. 2. The damaged intervertebral disc is removed to relieve nerve compression. 3. Interbody cages filled with bone graft are placed into the disc space to restore disc height. 4. Pedicle screws and rods are inserted to stabilize the vertebrae. 5. Real-time fluoroscopic X-ray guidance is used during the procedure to ensure accurate placement of implants. Over time, the bone graft allows the vertebrae to fuse together into a stable spinal segment. Advantages of PLIF Surgery PLIF spinal fusion provides several important benefits: • Effective nerve decompression • Restoration of disc height and spinal alignment • Stabilization of unstable spinal segments • Long-term relief from chronic back and leg pain • Improved spinal stability and function This procedure is widely used to treat degenerative lumbar spine conditions that require stabilization. Role of X-Ray Imaging During PLIF surgery, intra-operative fluoroscopy (real-time X-ray imaging) is used to guide accurate placement of pedicle screws, rods, and interbody cages. Postoperative X-ray radiographs demonstrate the spinal implants and fusion cage positioned between the vertebrae, confirming proper spinal alignment and stabilization. Follow-up imaging helps monitor progression of spinal fusion over time. Recovery After PLIF Surgery Recovery following PLIF surgery involves early mobilization and structured rehabilitation. Typical recovery milestones include: • Mobilization within 24–48 hours after surgery • Gradual return to walking and daily activities • Physiotherapy focused on core strengthening and spinal stability • Return to normal activities over several weeks depending on healing Rehabilitation is essential for maintaining spinal strength and preventing recurrence of symptoms.
