Robot-assisted minimally invasive transforaminal lumbar interbody fusion with contralateral facet decortication: a novel technique for posterolateral fusion

In traditional minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF), the primary fusion mass comes from the interbody space. In this case report of a 58-year-old female undergoing a MIS-TLIF for grade 2 spondylolisthesis, the authors demonstrate a novel MIS posterolateral fusion technique using robot-guided facet decortication. This method enhances the fusion surface area in patients with osteopenia or spondylolisthesis and advances robotic spine fusion strategies.
