AIM OF THE STUDY: To compare clinical findings with MRI findings and evaluate the role of physical examination in the diagnosis, localization of the level, site, size, and type of lumbosacral disc herniation.
MATERIALS AND METHODS: A prospective study of 104 patients with low back pain and/or sciatica was conducted et al.-Kindy Teaching Hospital between January to December 2022. All Participants were evaluated via history, clinical examination, and MRI. One hundred patients had a disc herniation in the lumbosacral region, which was confirmed by MRI assessment after clinical presentation and physical examination. The data were collected and analyzed by the chi-square test.
RESULTS: Most of the patients (84%) experienced pain in the lower back that radiated to the lower limb or limbs, and nearly half of the patients experienced paresthesia (48%). Sixty-six percent of the patients had a scoliotic list; limitation of lumbar spine movements was common in 96%, and a decrease in the straight leg raising test (SLR) was detected in 98%. Cross SLR "Well test" was positive in 64% of patients. The femoral nerve stretch test was positive in 40% of patients. Sixty-four percent were presented with neurological deficits, 42% with affected L5 nerve roots, 22% with affected S1 nerve roots, and no patients with L4 affected. Twenty-two percent showed a positive SLR test with an angle between 41 and 70°.
CONCLUSION: Proper correlation between clinical and MRI will help determine the lesion's level, horizontal location, herniation type, and herniated disc size in the lumbosacral region and achieve a more accurate diagnosis.
