3 Types and Causes of Kyphosis

There are three main types of abnormal kyphosis.: postural kyphosis, Scheuermann's kyphosis (Scheuermann's disease), and congenital kyphosis.

  1. Postural kyphosis is the most common type of kyphosis. This is more common in girls than in boys and typically appears during adolescence. Poor posture (slouching) and a weakening of the muscles and ligaments in the back (paraspinous muscles) cause postural kyphosis.
  2. Scheuermann's kyphosis also first appears during adolescence. This type of kyphosis is the result of a structural deformity of the vertebrae. It is more common to develop scoliosis (kyphoscoliosis) with Scheuermann's kyphosis than with the other types of kyphosis.
  3. Congenital kyphosis is the least common type of abnormal kyphosis. An abnormal development of the vertebrae during development prior to birth causes congenital kyphosis. This can lead to several of the vertebrae growing together (fusing) in kyphosis.
  4. There are other disorders that can lead to different types of kyphosis in adults.
