[edit] Discussion of Insufficiency fracture

• Insufficiency fractures occur when a normal stress fractures an abnormal bone.
• Some clinical entities that reduce elastic resistance of bone and thus predispose it to insufficiency fractures include
  • Bone disease (osteogenesis imperfecta, Paget disease)
  • Metabolic disorders (osteoporosis, hyperparathyroidism, rickets)
  • Inflammatory conditions (osteomyelitis, rheumatoid arthritis)

• These fractures should be distinguished from a stress fracture, which is a fracture that occurs when excessive stress is applied to normal bone.
