Dysplastic LV5  and Lumbosacral Stability

Purpose To study the impact of dysplastic L5 Vertebra on Lumbosacral Stability. Does a dysplastic vertebra a cause of instability at the lumbosacral junction? Methods This was a retrospective cohort study conducted between January 2023 and December 2023. The requisite radiological materials included plain radiographs and MRI scans of the lumbar spine. Two groups of patients were contrasted, those with dysplasia LV5 and those without. Key measurement was the wedge angle, and other measurements were spinopelvic measurements, Pfirman stage of disc degeneration, presence of pars fracture and vertebral slippage. Results Compared to controls, the dysplastic group revealed an increased frequency of sciatica (p = 0.007), disc degeneration, pars fractures and slippage (p < 0.001). There were also differences in lumbar lordosis, sacral slope and pelvic index (p < 0.05). Conclusion Dysplastic LV5 vertebrae significantly impact the stability of the lumbosacral junction, leading to instability. Low back pain is as a result of disc degeneration, spondylolysis, and later facet joint disease.
