Trans-foraminal versus posterior lumbar interbody fusion: comparison of surgical morbidity

Abstract Background: Posterior lumbar interbody fusion (PLIF) and trans-foraminal lumbar interbody fusion (TLIF) are both accepted surgical approaches for spinal fusion in spondylolisthesis and degenerative disc disease. The unilateral approach of TLIF may minimize the risk of iatrogenic durotomy and nerve root injury; however, there is no definitive evidence to support either approach. We review our experience with TLIF versus PLIF to compare operative complications. Methods: We retrospectively reviewed 119 consecutive cases of PLIF or TLIF performed for degenerative disc disease or spondylolithesis at a single institution over 5 years and examined the incidences of operative complications and outcomes. Results: PLIF was performed in 76 (63%) patients and TLIF in 43 (37%). Patients were 48±13 years old and presented with mechanical back pain [109 (92%)], radicular pain [95 (80%)], and radicular motor weakness [10 (8%)]. Patients undergoing PLIF and TLIF had similar baseline demographic, clinical,...
