Reduced Length of Stay and Contained Hospital Costs with Cortical Pedicle Screws: A Prospective Cohort Study

BACKGROUND CONTEXT: The use of cortical pedicle screws (CPS) with transforaminal interbody fusion (TLIF) is an alternative to traditional fixation with posterior pedicle screws (PPS) with or without TLIF. Reduced surgical trauma and dissection during CPS may lead to faster patient recovery. Despite higher device cost, CPS+TLIF could be associated with total cost decrease and improved outcomes in treatment of spondylolisthesis with spinal stenosis if improvements exist in the associated length of stay or other inpatient charges.
