A hip fracture is a break in the thigh bone just below the hip joint. The hip joint consists of a ball at the top of the thigh bone (femur) and a rounded socket (acetabulum) in the pelvis. Most hip fractures occur in the neck of the femur 1-2 inches below the ball portion of the hip.

Factors that may contribute to a hip fracture include:

  • Falls (the most frequent cause of hip fractures)
  • Osteoporosis —a bone-thinning condition that weakens all bones including the hip
  • Motor vehicle accidents and other types of major trauma
  • Stress fractures in athletes (rare)
  • Bone conditions such as osteomalacia (rare)
  • Bone tumors (rare)
