A 79-year-old male with prior right L3-4 microdiscectomy presents with persistent right L3 radiculopathy; the condition is due to severe spondylosis at L3-4 with retrolisthesis, disc collapse with modic endplate changes, and severe foraminal stenosis compressing right L3 nerve root. The patient underwent L3-4 interbody arthrodesis with a L50 × W22 × H13-mm 12° lateral lumbar interbody fusion cage. (A) Preop magnetic resonance image showing the aforementioned findings. (B) Preop lateral upright radiograph showing initial SL = 6.6° at L3-4 level and LL = 46.2°. (C–E) Postop lateral upright radiographs obtained after surgery (SL = 12.9°, LL = 46.2°), at the 6-month follow-up (SL = 12.9°, LL = 46.5°), and the last follow-up (SL = 13.2°, LL = 46.5°), respectively.
