Ge DH, et al. - In this single-center retrospective cohort study, researchers compared open transforaminal lumbar interbody fusion (O-TLIF) and bilateral minimally invasive surgery (MIS) Wiltse approach TLIF (Wil-TLIF), with respect to perioperative and postoperative outcomes. The patients undergoing a single-level primary posterior lumbar interbody fusion between 2012 and 2017 were examined via chart review. They divided the cases as Open TLIF (traditional midline exposure including lateral exposure of transverse processes) or bilateral paramedian Wiltse TLIF approach. Findings revealed that the lowest estimated blood loss, length of stay, readmission rates, and complications were seen with the minimally invasive paramedian Wiltse approach, however, this approach was associated with longer fluoroscopy times when compared with the traditional open approach.
