Scheuermann's disease (, though very often mispronounced as 'Sherman') is a
self-limiting skeletal disorder of childhood. It is also known as
Scheuermann's kyphosis (since it results in
kyphosis),
Calvé disease, and
idiopathic juvenile kyphosis of the spine. It is named after
Holger Werfel Scheuermann. Scheuermann's disease describes a condition where the
vertebrae grow unevenly with respect to the
sagittal plane; that is, the
posterior angle is often greater than the
anterior. This uneven growth results in the signature "wedging" shape of the vertebrae, causing
kyphosis.
