A patient was diagnosed preoperatively with degenerative spondylolisthesis and lumbar spinal stenosis at L4-5 level, and underwent minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF). Radiographic images (A,B) and MRI (C) were taken preoperatively. The immediate post-operative lumbar spine lateral view (D) and lumbar antero-posterior view (E) are shown. Cage subsidence (black arrow) and screw halo sign (white arrow) were seen on the last follow-up images (F,G).
