Figure 2: A 37-year-old male patient (patient number: 15 in the tables) with DDD and HNP at the L4-5 level. Lateral standing X-rays showing (a) preoperative, (b) early postoperative, and (c, d, e) final follow-up X-rays including standing lateral neutral, extension, and flexion views taken at 50 months after the surgery. Note that there is 1.9 mm reduction of the DH at the final follow-up examination compared to the early postoperative period. The operated level remained stable in extension and flexion views. The patient’s VAS-B, VAS-L, and ODI scores were 1.4, 2, 4.4, respectively, at the final follow-up visit. The patient rated his result as “excellent.”
