Correlation between direction of prolapsed intervertebral disc (PIVD) and lumbar vertebral alignment

Abstract

Abstract Low back pain results from a deviation from the spine's neutral position. The lumbar spine experiences the highest mechanical and weight bearing loads due to its close proximity to the centre of gravity in the human body. Low back discomfort is frequently brought on by herniated lumbar discs. Complete disc prolapse can be caused by a number of things, including severe injury, persistent strain, and weak core muscles. The study's objective was to establish a link between direction of a prolapsed intervertebral disc (PIVD) and lumbar vertebral alignment.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 23.0 was used for statistical analysis. The study found that 47% of 102 people aged 46-50 with PIVD were affected, with 68.62% at the L4-5 level and 42.2% at the L5-S1 level, with posterocentral and biforaminal locations being most common. The findings suggest that there was a significant relationship between the direction of prolapsed intervertebral disc (PIVD) and lumbar vertebral alignment.
