The femur is the body’s longest, strongest bone. So when it breaks, there’s usually a lot of force involved. And⎯no surprises⎯the primary cause of a broken femur is a car crash. Read on to learn other causes and cures for a broken thighbone.

Causes & Triggers

  • Abnormal twisting
  • Forceful fall or blow
  • High-impact collision (especially motor vehicle accident)
  • Osteoporosis, cancer or other bone-weakening conditions
  • Repeated stress injuries
  • Trauma

Signs & Symptoms

  • Bruising
  • Inability to bear weight
  • Limited or no range of motion
  • Obvious deformity
  • Pain
  • Swelling

Tips & Treatments

  • Like all fracture, the severity of femoral fracture varies.
  • Since strong bones can help prevent this condition, it is a good idea to participate in regular weight-bearing exercise such as walking, and strengthening or weight training.
  • This type of break usually requires surgical repair with metal pins, screws, plates and rods, followed with splinting and physical rehabilitation.
  • Because proper healing is dependent on proper treatment, seek the expertise of a well-qualified orthopedic specialist.
