Abstract
This literature review examines the relative placement of the interbody cage with respect to the unilateral screw construct to address the need for bilateral screw placement versus unilateral screw placement. Transforaminal lumbar interbody fusion (TLIF) has become a widely used technique for correcting lumbar intervertebral pathologies. This review addresses the necessity for further study on the effects of the relative position of intervertebral cage placement on the outcome of lumbar spine surgery after TLIF with unilateral pedicle screw fixation. Previous studies have addressed various factors, including posterior screw fixation, cage size, cage shape, and number of levels fused, that impact the biomechanics of the lumbar spine following TLIF. A simple survey of the literature was conducted. A search of the English literature was conducted using the keywords 'TLIF,' 'transforaminal lumbar interbody fusion,' 'graft placement,' 'graft position,' 'cage position,' 'cage placement,' 'unilateral pedicle screw,' 'unilateral TLIF cage placement,' 'lumbar biomechanics,' 'lumbar stability,' 'lumbar fusion,' and 'lumbar intervertebral cage' with various combinations of the operators 'AND' and 'OR' and no date restrictions.
