A 38-year-old man with lumbar disc herniation (LDH) at L4–5 and L5–6. Lateral (A) radiograph showing mild degenerative changes at L4–5 and L5–6. Magnetic resonance images (B and C) showed LDH at L4–5 and L5–6. The patient underwent discectomy and DIAM implantation at L4–5 (white arrow) (D). At 15 years after discectomy at L4–5 and L5–6 and DIAM implantation at L4–5, anteroposterior radiograph (E and H) and computed tomography scans (F and G) show severe degenerative changes at L4–5 and L5–6 and maintenance of DIAM at L4–5 (white arrows)
