Scheuermann's disease

Scheuermann's disease (/ˈʃuːərmən/, 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.
