There are high reoperation rates, and posterior interbody fusion has not been reported to help. The current study aimed to utilize a nationwide database to investigate outcomes of spinal fusion for spondylolisthesis in young patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>The PearlDiver database was queried for patients &lt;21 years old who had undergone lumbar spinal fusion for spondylolisthesis between 2010 and 2020. Patients were divided into 4 cohorts based on surgical approach: (1) posterior spinal fusion with posterior instrumentation (PSF), (2) posterior spinal fusion with posterior instrumentation plus interbody (PSF+I), (3) anterior spinal fusion without posterior instrumentation (ASF), and (4) anterior spinal fusion plus posterior instrumentation (A+PSF). Patients with &lt;2 years of follow-up were excluded. The primary outcome was reoperation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Of 33,945 patients with spondylolisthesis, 578 (1.7%) underwent lumbar spinal fusion: 236 (40.8%) had PSF, 219 (37.9%) had PSF+I, 66 (11.4%) had ASF, and 57 (9.9%) had A+PSF. The mean age was 16.5 \u00b1 1.1 years, and the mean follow-up was 5.4 \u00b1 2.9 years. A higher percentage of girls underwent surgery compared with boys (2.0% versus 1.4%). Survival analysis using all-cause reoperation as the end point demonstrated an overall 5-year reoperation-free survival rate of 85.5% (95% confidence interval [CI]: 82.5% to 88.6%). The overall reoperation rate within 5 years was significantly different depending on the approach, with A+PSF being the lowest at 7.0% (PSF = 11.9%, PSF+I = 10.5%, and ASF = 31.8%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>This is the largest reported series of spondylolisthesis surgery in young people. The lowest rate of revisions within 5 years was for a combined approach of A+PSF. The 5-year risk of reoperation of 31.8% for a stand-alone ASF appeared to be unacceptably high compared with other approaches, and was over 4 times higher than A+PSF (7.0%). Consistent with previous clinical series, the addition of an interbody fusion to a PSF did not decrease the reoperation rate and did not appear to offer any advantages to a PSF alone.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence:<\/jats:title>\n                    <jats:p>\n                      Therapeutic\n                      <jats:underline>Level III<\/jats:underline>\n                      .
