A typical case. A 61-year-old man suffered from L4/5 bilateral spinal canal decompression, fusion, and pedicle screw instrumentation fixation. Before operation, VAS (low back pain) was 5; VAS (radicular pain), 8; JOA, 14; and ODI, 57.6. Two years postoperatively, VAS (low back pain) was 1; VAS score (radicular pain), 1; JOA, 26; and ODI, 10.8. a Preoperative lumbar radiography. b Preoperative lumbar MRI indicating severe stenosis of the L4/5 spinal canal. c Three months after operation, lumbar radiography indicating that the bone graft between the right L4/5 transverse process has been absorbed and that between the left L4/5 transverse process is ossifying. d Two years after operation, lumbar radiography indicating that continuous bony bridge has formed between the left L4/5 transverse process
