Spinal fusion

A spinal fusion surgery is designed to stop the motion at a painful vertebral segment, an action which should decrease pain generated from the joint.

There are different approaches to lumbar spinal fusion surgery, and all involve adding bone graft to the spine to set up a biological response that causes the bone graft to grow between the two vertebral elements and create a fusion, thereby stopping the motion at that segment.For patients with the following conditions, if abnormal and excessive motion at a vertebral segment results in severe pain and inability to function, a fusion may be considered: Degenerative disc disease - Spondylolisthesis (isthmic, degenerative or post laminectomy spondylolisthesis) .Other conditions that may be treated by a spinal fusion surgery include a weak or unstable spine (caused by infections or tumors), fractures, scoliosis or deformity. A short animation plan is given at the following pages, to understand the fusion philosophy.
