Figure 1.

Preoperative radiographs of one 58 year-old male suffering from back pain for ten years and neurological intermittent claudication for one year (VAS: 7, JOA: 11, ODI: 58%), demonstrating discogenic back pain and pathological lumbar canal stenosis at L4-5 level (A-G). Microendoscopy-assisted MIS-TLIF accomplished bilateral canal decompression via the right approach, and patient’s symptoms relieved significantly following surgery (VAS:1, JOA:25, ODI:8%) (H-I). Lumbar CT scan demonstrated satisfactory interbody fusion during postoperative follow-up (J-K).
