Final answer:
Scoliosis is characterized by an abnormal lateral curvature in the frontal plane of the spine, with treatments varying based on severity.
Step-by-step explanation:
Scoliosis is a condition characterized by an abnormal, lateral curvature of the spine, often accompanied by a rotation of the vertebrae. This curvature occurs in the frontal plane (also known as a coronal plane), which divides the body into ventral (front) and dorsal (back) sections. Scoliosis is most prevalent among girls and can become more pronounced during periods of rapid growth, such as adolescence. Treatment may range from observation to the use of a back brace or surgery in severe cases.
