The operative duration, blood loss, length of stay, complications, Japanese Orthopaedic Association (JOA) score, visual analogue scale (VAS) score, MacNab classification and imaging data were collected preoperatively, postoperative 1\u2010week, final follow\u2010up and statistically analyzed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The surgery was completed successfully on all patients, and there were no serious complications, such as nerve or spinal cord injury or infection. In the PPEUL and ACDF groups, the operative duration were 56.63\u2009\u00b1\u20091.40 and 65.21\u2009\u00b1\u20092.45\u2009min, the intraoperative blood loss were 51.69\u2009\u00b1\u20093.23 and 50.51\u2009\u00b1\u20095.48\u2009mL, and the hospitalization duration was 5.75\u2009\u00b1\u20091.43 and 6.38\u2009\u00b1\u20092.16\u2009days.

There was no significant difference in intraoperative blood loss between the two groups, but the hospitalization and operative durations in the PPEUL group were significantly shorter than those in the ACDF group (\n                      <jats:italic>P\u2009&lt;<\/jats:italic>\n                      \u00a00.05). The VAS scores at postoperative 1\u2009week and final follow\u2010up were significantly improved compared with those before surgery. The JOA scores at postoperative 1\u2009week and final follow\u2010up were significantly improved compared with those before surgery, but there was no significant difference between the two groups at the last follow\u2010up. The intervertebral disc height of the adjacent segment at the last follow\u2010up was significantly lower in the ACDF group than in the PPEUL group (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.05), but there was no significant difference between the two groups in the intervertebral disc height of the surgical segment (\n                      <jats:italic>P\u2009&gt;<\/jats:italic>\n                      \u00a00.05). The rate of excellent and good results was 90.0% and 87.5%, respectively.
