Q76.2: Congenital spondylolisthesis

Congenital spondylolisthesis is a rare medical condition present at birth where one of the vertebrae (the bones in the spine) slips forward onto the bone underneath it. This misalignment can occur in any part of the spine, but it is most common in the lower back. This condition might cause moderate to severe back pain, especially after exercise or physical activity, numbness or weakness often spreading to the legs and feet, and difficulties in walking. Some individuals, however, may not experience any symptoms. Congenital spondylolisthesis is caused by abnormal bone formation while the baby is in the womb, resulting in the unusual arrangement of the vertebrae. The pain associated with this condition may increase with age and physical activity. The diagnosis is usually confirmed through a physical examination and imaging tests like X-rays or MRI scans.
