Hooman M. Melamed, MD, Neurosurgery, answeredThe risks of spinal fusion depend on age, overall medical condition of the patient, and the type of surgery. Some of the risks include, but are not limited to, infection, bleeding, nerve/muscle/tendon/ligament damage, paralysis, pain, numbness, deformity, loss or decreased range of motion, bowel/bladder dysfunction, dural tear, revision surgery, pseudoarthrosis, hardware failure, malpositioning of hardware, blindness, heart attack, stroke, blood clots, and death. However, most of the time the benefits of the surgery far out weigh the risks of surgery. My own father had a very successful spinal fusion back surgery and has done extremely well.

As with any surgical intervention there are risks to spinal fusion surgery. Those risks have been thoroughly described by other writers. However, two additional complications can arise. Firstly, pseudoarthrosis can occur which is when there is unsuccessful fusion of the vertebrae. There may be a fibrous union between spinal vertebrae but this is insufficient to limit movement. Secondly, symptoms may recur despite surgery because the success rate is not 100%.
