Anterolisthesis is a spinal condition characterized by the forward displacement of a vertebra in relation to the one beneath it. This slippage typically occurs in the lumbar (lower back) region of the spine, although it can also affect the cervical (neck) area. The condition is often graded on a scale from I to IV, based on the degree of slippage, with Grade I being mild and Grade IV being severe. Common causes of anterolisthesis include age-related degeneration of the spinal discs and joints, trauma or fractures, congenital spine defects, or repetitive stress
on the spine from activities such as heavy lifting or sports.
The symptoms of anterolisthesis can vary depending on the severity and location of the vertebral slippage. In many cases, individuals may experience lower back pain, stiffness, and reduced flexibility. If the displaced vertebra compresses nearby nerves, it can lead to radiating pain, numbness, or weakness in the legs—a condition known as sciatica. In more severe cases, individuals might also have difficulty walking, changes in posture, or issues with bowel and bladder control. Diagnosis typically involves physical examination and imaging studies
such as X-rays, CT scans, or MRI to assess the extent of slippage and nerve involvement.
