Scheuermann Disease, also known as juvenile kyphosis, is a condition that affects the spinal vertebrae in adolescents. It is characterized by excessive curvature of the upper spine, resulting in a rounded, hunched appearance. While "Scheuermann Disease" is a widely used term to describe this condition, there are a few synonyms that can be employed as well. One alternative term is "Scheuermann's Kyphosis", which emphasizes the abnormal kyphotic or forward bending curvature of the upper spine. Another synonym is "adolescent kyphosis", which highlights that this condition primarily affects young individuals during a critical growth period. Both these synonyms are used interchangeably and refer to the same spinal disorder.
