Femoral Stress Fracture

A Femoral stress fracture is a small crack in your thigh bone. It happens when the bone is put under too much stress over and over without enough time to recover. Instead of one big injury the bone slowly becomes weaker until a small crack forms. This injury is most common in runners and athletes who suddenly increase how much they train. If it is not treated early the crack can get bigger and become a complete break.

  • Deep pain in the thigh or groin
  • Dull aching pain
  • Pain that gets worse during running
  • Pain while jumping
  • Pain when putting weight on the leg
  • Pain while walking
  • Pain that gets better with rest at first
  • Pain that slowly gets worse over time
  • Limping
  • Weakness in the leg
  • Trouble running at full speed
  • A Femoral stress fracture usually starts as a tiny ache deep in your thigh or groin. At first the pain may only happen during running or sports and go away with rest. As the injury gets worse the pain can last longer and may even hurt while walking or standing. Some athletes notice they cannot run as fast or jump as well because of the pain.

  • Jumping over and over
