Prevalence of lumbar intervertebral disc herniation in Asymptomatic individuals on magnetic resonance imaging: a One year hospital based cross sectional study

Abstract

ABSTRACT BACKGROUND Lumbar intervertebral disc herniation is a common spinal condition often identified incidentally through Magnetic Resonance Imaging (MRI) in asymptomatic individuals. While symptomatic herniations are linked to pain, numbness, or neurological deficits, many individuals show disc abnormalities without any clinical signs. The increasing use of MRI has led to a higher detection rate of these incidental findings, raising concerns about overdiagnosis and overtreatment. Understanding the prevalence of asymptomatic disc herniation is vital to improve clinical decisionmaking, refine diagnostic strategies, and identify risk factors for potential progression to symptomatic conditions. Factors such as age, lifestyle, occupation, and genetic predisposition are believed to influence disc health, making comprehensive studies essential for better management strategies. OBJECTIVE To evaluate the prevalence of lumbar intervertebral disc herniation in asymptomatic individuals aged 20 to 80 years using MRI at a tertiary care hospital.
