Association Between Trendelenburg Sign and Lumbar MRI Abnormalities

The Trendelenburg sign is a common clinical finding indicating hip abductor dysfunction and altered pelvic stability. The relationship between the Trendelenburg sign, spinopelvic biomechanics, hip muscle strength, and lumbar magnetic resonance imaging (MRI) abnormalities remains insufficiently understood. This study aims to investigate the association between Trendelenburg sign positivity and lumbar MRI findings, including facet arthropathy, ligamentum flavum hypertrophy, multifidus muscle morphology, and psoas muscle characteristics, as well as spinopelvic biomechanical parameters and hip abductor muscle strength.
