ABSTRACT
Spinal fusion is undertaken for three basic reasons. First, to stabilize the unstable spine; second, to provide long-term correction of spinal deformity; and third, to relieve pain.
Indications 1. Stabilization. The spine may be rendered unstable by trauma, infection, tumour, iatrogenic injury (failed or inappropriately performed surgery), spondylolysis and spondylolisthesis and, to a lesser extent, degenerative disc disease.
