Congenital spondylolisthesis is characterized by dysplasia of the facet joint or congenital defect in the pars. Our study highlights the clinical and radiological profile, various treatment options, and outcomes in patients with pediatric congenital lumbar and lumbosacral spondylolisthesis. A retrospective analysis and follow-up of 22 patients were conducted presented with radiological diagnosis of congenital lumbar/lumbosacral spondylolisthesis (2018-2021). Twenty patients (91%) had L5-S1 listhesis and two patients (9%) had L4-L5 listhesis. Six (27.3%) patients had low-grade listhesis (grades 1-2), 16 (72.7%) had high-grade listhesis (grades 3-5). Seventeen (77.3%) had S1, three (13.6%) had L5, and two (9%) had both L4-L5 radiculopathy. All patients had neurogenic claudication. One had an associated spina bifida occulta. Six (27.3%) patients underwent two-level fixation, and 16 (72.7%) underwent three-level fixation. Minimally Invasive Transforaminal Lumbar Interbody Fusion (MIS TLIF) was done in two patients. Revision of at least one screw was done in three patients. After one year of follow-up, all the patients had 75-100% relief in radicular pain and neurogenic claudication. The Oswestry Disability Index (ODI) score in preop for all patients was 41-60% and postoperatively they showed an improvement in ODI score (0-20). The postoperative low back pain score on the Numeric Rating Scale was 0-1 for all patients. Congenital lumbar spondylolisthesis usually presents with high-grade listhesis. Management of such cases is a surgical challenge but posterior decompression resulted in relief of pain in all patients. However, in situ fixation without reduction is also effective in selective cases where attempts to reduce the listhesis result in a decline in intraoperative neuromonitoring parameters.
