Enhanced Recovery after an Innovative Percutaneous Endoscopic Transforaminal Lumbar Interbody Fusion for the Treatment of Lumbar Spinal Stenosis: A Prospective Observational Study

Figure 5

A 65-year-old female patient was diagnosed as lumbar spinal stenosis with degenerative instability and was treated by PE-TLIF. (a, b) Preoperative MRI demonstrated a lumbar spinal stenosis at L4/5. (c, d) A good implantation position was presented through X-ray images taken 7 days after the operation. (e) A standard lumbar fusion was presented via CT scan image at 6 months after the operation. (f, g) X-ray images demonstrated a good implantation position at final follow-up.
