Correlation Between Direction of Prolapsed Intervertebral Disc (PIVD) And Lumbar Vertebral Alignment

Abstract

Abstract Purpose: The purpose of this research was to establish a link between direction of a prolapsed intervertebral disc (PIVD) and lumbar vertebral alignment. Methods: This cross-sectional study included 102 participants with prolapsed intervertebral discs in the lumbar segment and lumbar vertebral mal-alignment of both sexes between the ages of 30 and 50 who had undergone MRI and X-ray for the lumbo-sacral spine. The Numerical Pain Rating Scale (NPRS) was used to assess outcome, MRI scans were used to determine the direction and amount of PIVD, and lumbar spinal alignment was assessed using X-rays in the AP and lateral views. SPSS version 26.0 was used for statistical analysis. Findings: Among the 102 participants, The study found that only 2.94% of 102 participants had Prolapsed Intracranial Disc Disease (PID) at the L1-2 level, with many on multiple levels. Prolapsed intervertebral discs were prevalent in 46.07% of individuals, with scoliosis in 33.33%, exaggerated lumbar lordosis in 4 subjects, and anterolisthesis in 20.59%. The study found a significant correlation between posterocentral and anterolisthesis, biforaminal and flatback, right paracentral and left paracentral prolapse and scoliosis (p<0.0001), with biforaminal direction being particularly significant for anterolisthesis and retrolisthesis (p=0.0050, 0.0014). The lumbosacral angle had a mean value of 31.79, and the mean of pain on rest was 1.99±1.38 and during activity was 5.51±1.66. Conclusion: It concluded that there was a significant relationship between the direction of prolapsed intervertebral disc (PIVD) and lumbar vertebral alignment.
