What is the difference between Spondylolisthesis and Spondylolysis?
Though both spondylolisthesis and spondylolysis involve fractures in the spine, they differ in their location and presentation. Spondylolysis refers to a stress fracture that occurs at the pars interarticulares, which are the bony bridges connecting the vertebral bodies in the lumbar and sacral regions. This type of fracture is often caused by repetitive stress on the spine during activities like gymnastics or weightlifting. In contrast, spondylolisthesis refers to a forward slippage of one vertebra onto another, usually due to a defect or fracture in the facet joints or pars interarticulares. This can result in pain, stiffness, and neurological symptoms depending on the severity and location of the slippage. Treatment options for both conditions may include conservative measures like rest, bracing, physical therapy, and pain management, as well as surgical intervention if necessary to stabilize the spine and alleviate symptoms.
