Back pain affects approximately 80% of individuals in the United States at some point in their lives. Although most patients with low back pain can be managed non-operatively, lumbar fusion may be used in certain emergent situations or in carefully selected patients with specific anatomical derangements when conservative therapy has failed. In considering surgical intervention, however, patients should receive education concerning alternative treatments, as well as the risks and benefits associated with spinal surgery. Risk factors for nonunion of a lumbar spinal fusion include, but are not limited to: use of tobacco or nicotine in any form, alcoholism, diabetes, osteoporosis, malnutrition, or repeated fusion attempts.
This policy applies to all approaches to lumbar fusion, including minimally invasive approaches, with the exception of Axial (Percutaneous) Interbody Lumbar Fusion which is addressed separately in policy #IV-91.
Osteomyelitis: Bone infection.
Scoliosis: Sideways curve of the spine that makes the spine look more like an "S" or "C" than a straight "I."
Cobb angle: Measurement of the degree of side-to-side spinal curvature, as demonstrated on x-ray. This measure is used to track the progression of scoliosis.
Kyphosis: Forward bending (curving) of the spine which produces a roundback deformity.
Pseudarthrosis: Formation of a false joint at the site where a fractured bone has failed to heal.
Spinal instability: >3mm of translation and/or 10 degrees or more of angulation of one vertebra compared to the adjacent vertebra in a spinal motion segment.
Spinal stenosis: Abnormal narrowing of the spinal canal (central stenosis), lateral recess and/or neural foramina (foraminal stenosis).
Spondylolisthesis: A forward dislocation of one vertebra over the one beneath it, producing pressure on spinal nerves.
Degenerative disc disease: A condition involving the gradual degeneration of the intervertebral discs, also known as spondylosis.
