Typical case. The patient was a 40-year-old woman who was diagnosed with lumbar disc herniation (L4/5), cauda equina syndrome, and L3/4 disc degeneration and underwent L3-5 hybrid surgery with PEEK rods. a shows the lumbar X-ray before the operation. b shows the sagittal-plane MRI image of the lumbar region before the operation.c, d show the MRI images of the L3/4 and L4/5 sections of the lumbar region before the operation, respectively. e shows the lumbar X-ray at the 2-year follow-up. f shows the sagittal MRI image of the lumbar region at the 2-year follow-up. g, h show the MRI images of the L3/4 and L4/5 sections of the lumbar region at the 2-year follow-up, respectively. L3-5 were fixed segments, L3/4 was nonfused segments, the modified Pfirrmann classification of L3/4 was 6 both pre- and postoperatively, and the DHI was 0.28 preoperatively and 0.26 postoperatively. The modified Pfirrmann classification of the upper adjacent segment L2/3 was 2 both pre- and postoperatively, and the DHI was 0.33 preoperatively and 0.35 postoperatively. No significant degeneration was seen
