Lumbar spinal fusion permanently joins two or more vertebrae in the lower back to eliminate painful motion at a damaged segment. The surgeon uses bone graft, screws, and rods to stabilize the spine while the vertebrae fuse into solid bone over 3-6 months. It treats degenerative disc disease, spondylolisthesis, spinal stenosis, and fractures.
Laminectomy (decompression surgery) removes part of the vertebral bone (lamina) to create more space for the spinal cord and nerves. It relieves pressure caused by spinal stenosis — a narrowing of the spinal canal common in patients over 60. The procedure can be performed alone or combined with fusion for stability.
Microdiscectomy is a minimally invasive procedure to remove the portion of a herniated disc pressing on a spinal nerve. Through a 1-inch incision, the surgeon uses a microscope to precisely remove the disc fragment causing sciatica (leg pain, numbness, or weakness). One of the most successful spine surgeries with 85-95% relief of leg symptoms.
Scoliosis surgery corrects abnormal curvature of the spine using rods, screws, and bone graft to straighten and stabilize the spine. In adolescents, posterior spinal fusion is the standard approach for curves exceeding 45-50 degrees. Adult scoliosis surgery addresses pain, progression, and spinal imbalance through decompression and/or fusion.
