Transforaminal Lumbar Interbody Fusion Versus Instrumented Posterolateral Fusion In Degenerative Spondylolisthesis: An attempt to evaluate the superiority of one method over the other.

Spondylolisthesis is a complex and challenging multifactorial condition. Spondylolisthesis is the forwards slippage of one vertebra on another.Degenerative spondylolisthesis differs from spondylolytic spondylolisthesis by the absence of a pars interarticularis defect (spondylolysis), i.e., in Degenerative spondylolisthesis the whole upper vertebra (vertebral body and posterior part of the vertebra including neural arch and processes) slips relative to the lower vertebra.Degenerative changes within the facet joints are partly responsible for allowing forward slip.It is more common in people over age 50, and far more common in individuals older than 65.
