The literature has had some conflicting evidence regarding the effective management of lumbar spondylolisthesis (LS). Herein, we review active and prospective clinical trials to identify the emerging trends for the management of LS. A systematic search was conducted utilizing the NIH Clinical Trials database using the search term “lumbar spondylolisthesis” on February 2, 2022. Currently active and prospective clinical trials for LS were included and analyzed. All statistical analyses were performed on R 4.1.2. We identified 37 clinical trials. Nearly half the trials (n = 18, 48.6%) include novel technologies; 6 (16.2%) are comparing surgical approaches, of which 4 (67%) include decompression alone versus decompression with instrumented fusion; 6 (16.2%) are evaluating perioperative pain management protocols, of which 3 (50%) include bupivacaine or ropivacaine; 3 (8.1%) are evaluating alternative medicines in LS; 2 (5.4%) are observational studies about the natural history of LS; 1 (2.7%) involves surgical infection prophylaxis; and 1 (2.7%) is evaluating AK1320 microspheres. The 18 trials involving novel technologies include 3D-printed titanium cages (n = 3, 16.7%), interbody implants (n = 4, 22.2%), bone graft materials (n = 4, 22.2%), and miscellaneous intraoperative devices (n = 7, 38.9%). The top 3 outcomes measured were Oswestry Disability Index (n = 28, 75.7%), visual analog scale (n = 21, 56.7%), and postoperative radiographs (n = 16, 43.2%). Patient-reported outcome measures (PROMs) were included in 34 (91.9%) trials, while 23 (62.2%) trials included lumbar spine imaging. LS can often require a multifaceted approach. Novel technologies and utilization of PROMs appear to be a significant emerging trend in LS management.
