Spondylolisthesis is a spinal disorder in which one or more vertebrae become displaced toward the front of the body, usually in the lumbar spine (lower back), and commonly following a fracture. Any movement or activity that causes pressure on the vertebrae can cause its onset, such as improper bending or lifting, gymnastics, or high-impact sports. However, spondylolisthesis is generally classified in 5 different types: isthmic (low-grade, from a slip or fracture), degenerative (resulting from arthritis or joint remodeling), traumatic (rare, from acute fracture), pathologic (damage resulting from disease or tumor), and dysplastic (rare, from congenital malformation).
Treatment can be either surgical, or non-invasive. A combination of non-steroidal anti-inflammatory drugs (NSAIDs) and physical therapy can often help manage pain or swelling.
