Degenerative spondylolisthesis (DS) is a common pathology where anterior-posterior access can be advantageous. This study aimed to evaluate operative, radiological and functional outcomes of PTP fusion in the management of symptomatic DS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A multi-centre cohort study was conducted, involving 108 consecutive patients who underwent PTP fusion for low-grade (Grade I\u2013II) DS.

The cohort\u2019s average operative time was 115\u00a0minutes, and the psoas retraction time was 14\u00a0minutes. The cohort had an average slip of 5.9\u00a0mm, which was reduced to 0.8\u00a0mm (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001) postoperatively. Statistically significant radiological improvements were observed in lumbar lordosis (\u03945\u00b0), segmental lordosis (\u03944\u00b0), anterior disc height (\u0394 4.2\u00a0mm) and posterior disc height (\u0394 2.1\u00a0mm). No major vascular or visceral complications were encountered. The sustained neurological complication rate was 1.9%, and patients maintained improved functional outcomes through the 1-year follow-up.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>PTP is a safe approach for managing low-grade DS, showing significant postoperative correction of spinal alignment.
