Risk Factors

Factors that may increase your chances of hyperlordosis include:
  • Achondroplasia—a genetic disorder that results in abnormal cartilage growth and dwarfism
  • Spondylolisthesis—displaced vertebrae of back
  • Neuromuscular disorders such as muscular dystrophy or cerebral palsy
  • Congenital abnormalities of the spine
  • Back surgery
  • Hip disorders
  • Poor posture
  • Abnormal vertebral bodies—more commonly found in children with hyperlordosis
  • Hyperkyphosis—An exaggerated outward curve of the thoracic spine
  • Osteoporosis
  • Disc problems
  • Obesity
