A Prospective Study on Incidence and Diagnosis of Lumbar Spondylolisthesis in a Tertiary Care Hospital
Background: Normal inward curvatures are observed in both cervical and lumbar regions of the vertebral column. Because of these lordotic curvatures they help in shock absorption and support the weight of the head. Spondylolisthesis happens when one vertebra slips forward over the vertebra underneath it. This condition for the most part creates in the lumbar area of the vertebral section. It is due to the lumbar spine being exposed to directional pressures while carrying and distributing most of the body weight during activity and at rest. Such a combination of weight bearing and multidirectional movement may cause forward slippage of any random lumbar vertebra over the vertebra beneath it.
Methods: This observational study was conducted on patients presented with low back pain and patients enrolled were clinically and radiologically investigated. Data regarding age, sex and occupation were recorded.
Results: Out of 950 cases presented with Low Back Pain, only 45 cases was reported to have symptomatic spondylolisthesis. It was observed that majority of cases were seen in the age group of 35 to 55 years with higher preponderance among males.
Conclusions: Incidence of symptomatic lumbar spondylolisthesis was high. Sex ratio among presenting cases was observed to be higher in males. Cases were clinically examined and diagnosed radiologically. Most of the cases were managed conservatively. Imaging remains the only tool to facilitate neurosurgery related decision making.
