Three main types of hyperkyphosis and their causes include:

  • Postural—the most common abnormal type caused by bad posture
  • Congenital—a type that is present at birth, frequently with abnormalities of the vertebral bodies
  • Scheuermann’s—a type that is genetic, but appears during the teenage years

Other causes of hyperkyphosis are unknown.
