Lumbar Disk Herniation: A Clinical Epidemiological and Radiological Evaluation

Abstract

BACKGROUND: A herniated disc in the spine is a condition during which a nucleus pulposus is displaced from intervertebral space. AIM: The study aimed to investigate and observe variation of clinical, epidemiological, and radiological aspects for patients suspected of lumbar herniation based on observed evaluation of CT and MRI imagery. METHODS: This is a cross-sectional study conducted during the periods March 2015 and November 2019. Patients were subjected to MRI and CT based on the emergency or scheduled of diagnose. All MRI scans were obtained with 1.5 tesla MRI machine and for CT had undergone examinations with one of the following equipment: Siemens with 128 slice and Phillips 64 slice. The patients were placed in supine position. RESULTS: Overall 194 symptomatic patients were recruited as a participant in this study, 118 men and 76 women with an average age of 44.9 ±10.4 years. Patients belong to the active age (35–44-years-old and 45–54-years-old) appeared to have the highest percentage of lumbar disk herniation (LDH) 30.9% and 25.8%, respectively. There were a significant association between such as epidemiological data (such as gender, BMI, age groups, and employment status) and presence of LDH, p ˂ 0.05. Acute pain was presented in 69.07% of patients and according to complaint associated with low back pain (LBP), most of them 47.4% appeared with Right Sciatica. MRI is the most diagnostic methods used in evaluation of LDH in 52% of patients, and CT was used in 48% of them. The most common changes were between L2-L3, L3-L4, and L4-L5. Furthermore, the grading findings which corresponding to lumbosacral segment were Grade I and Grade II. Grade V was less common. CONCLUSION: This study involving patients with lumbar disk herniation and associated LBP showed that a combination of clinical features and epidemiological predicted the presence or absence of a significant association. Further research is required to validate these findings in different types of LDH and LBP for other findings and conditions.
