Changes in the pre- and postoperative NRS (a) and JOA (b) scores. NRS (a) showed a decreasing trend, and JOA (b) showed an increasing trend. The postoperative NRS and JOA scores were significantly improved compared with preoperative values , but the improvements were most obvious within 6 months postoperatively. During 6 months postoperatively, NRS and JOA scores at each follow-up time improved significantly compared with the previous follow-up value (, #, &, $: ). However, after 6 months postoperatively, NRS and JOA scores did not change significantly .
