Doctors don't know what causes the most common type of scoliosis — although it appears to involve hereditary factors, because the disorder tends to run in families. Less common types of scoliosis may be caused by:

  • Neuromuscular conditions, such as cerebral palsy or muscular dystrophy
  • Birth defects affecting the development of the bones of the spine
  • Injuries to or infections of the spine
