Anterior Lumbar Interbody Fusion Reduces Thecal Sac Compression in the Setting of Degenerative Spondylolisthesis

Surgical management for central and lateral recess thecal sac compression in the setting of degenerative spondylolisthesis (DS) has traditionally involved a posterior approach to decompression with associated fusion [1,2]. However, the posterior approach to lumbar interbody fusion (PLIF) involves significant disruption of the posterior elements, entrance into the spinal canal, and nerve root retraction, which contribute to epidural scarring and perineural fibrosis that may be associated with delayed recovery and chronic radiculopathy [3,4].
