Sacroiliac joint dysfunction in patients with herniated lumbar disc: A cross-sectional study

Abstract

Objectives:

To determine the relative frequency of sacroiliac joint dysfunction in a sample of patients with image proven lumbar disc herniation.

Methods:

A single group cross-sectional study was conducted in a three year period from 2007 in an outpatient clinic at a university hospital. Overall, 202 patients aged more than or equal to 18 years with image proven herniated lumbar disc and with physical findings suggestive of lumbosacral root irritation were included.

Results:

Overall, 146 (72.3%) participants had sacroiliac joint dysfunction. The dysfunction was significantly more prevalent in females ( $\mathit{p}\mathrm{<}0.001$ , adjusted OR=2.46, 95% CI=1.00 to 6.03), patients with recurrent pain ( $\mathit{p}\mathrm{<}0.005$ , adjusted OR=2.33 with 95% CI=1.10 to 4.89) and patients with positive straight leg raising provocative test ( $\mathit{p}\mathrm{<}0.0001$ , adjusted OR=5.07, 95% CI=2.37 to 10.85). There was no significant relationship between the prevalence of SIJD, and working hours, duration of low back pain, or body mass index.

Conclusions:

Sacroiliac joint dysfunction is a significant pathogenic factor with high possibility of occurrence in low back pain. Thus, regardless of intervertebral disc pathology, sacroiliac joint dysfunction must be considered in clinical decision making.
