What are some common spinal disorders?

The selection of herniated discs, scoliosis, spondylolisthesis, and spinal stenosis as common spinal disorders is accurate because these conditions directly affect the spine and its function.

Herniated discs occur when the soft material inside the spinal discs pushes out through a tear in the outer layer, leading to pain and nerve compression. Scoliosis is characterized by an abnormal lateral curvature of the spine, which can affect posture and lead to pain or breathing difficulties in severe cases. Spondylolisthesis involves a condition where one vertebra slips over another, often leading to pain and instability in the spine. Spinal stenosis refers to the narrowing of the spinal canal, which can compress nerves and lead to pain, weakness, or numbness, especially in the legs.

These conditions are prevalent in various populations and can significantly impact mobility and quality of life. In contrast, the other options include disorders that either do not primarily affect the spinal structure or are systemic conditions not limited to spinal issues.
