Stress Fracture of the Femur

What is a stress fracture of the shaft of the femur?

A stress fracture of the shaft of the femur is an incomplete crack in the thighbone (femur). Physiotherapy plays a key role in treating this injury, helping to manage pain, promote healing, and restore strength and function.

How does a stress fracture of the shaft of the femur happen?

Exactly! Stress fractures of the femoral shaft happen when the balance between bone resorption (breakdown) and formation is disrupted. If bone removal outpaces new bone growth in response to repetitive loading—like in distance runners—the femur develops weak spots that can crack, causing a stress fracture. This underscores the importance of proper training progression and recovery to allow bones to adapt safely to increased stresses.

What are the symptoms of a stress fracture of the shaft of the femur?

A stress fracture of the shaft of the femur is characterised by a dull ache felt in the front of the thigh that will develop over a period of weeks. The pain is often hard to localise and may even be felt in the knee. The pain is frequently made worse by exercise; however, it may also be felt during walking, rest and even at night. Other symptoms may include:

  • Tenderness or soreness when pressing on the front of the thigh
  • Swelling or mild bruising in the thigh area
  • Muscle stiffness or tightness around the thigh
  • Weakness or difficulty bearing weight on the affected leg
  • A sensation of discomfort or instability during movement

What should I do if I have a stress fracture of the shaft of the femur?

Exactly! If you have or suspect a stress fracture of the femoral shaft, it’s important to seek prompt evaluation from a sports medicine specialist, orthopedic doctor, or physiotherapist. Early diagnosis and management help prevent worsening of the injury and promote optimal healing. Avoid continuing high-impact activities until you have been assessed.

Physiotherapy treatment for a stress fracture of the shaft of the femur.

Physiotherapy is important in the treatment of a stress fracture of the shaft of the femur. Initially, your physiotherapist can provide you with a diagnosis. This may require the referral for imaging techniques such as a MRI scan. From this your physiotherapist can develop an appropriate treatment plan. This may initially involve a period of rest, bracing and the use of crutches and icing to help with your pain. Other treatments include:

  • Gradual weight-bearing exercises to promote healing without overloading the bone
  • Low-impact cardiovascular activities like swimming or cycling to maintain fitness
  • Strengthening exercises targeting the thigh, hip, and pelvic muscles to support the femur
  • Stretching and mobility exercises to maintain flexibility and prevent stiffness
  • Gait training to correct walking patterns and reduce stress on the injured leg
  • Education on activity modification and load management to avoid aggravating the injury

What shouldn’t I do if I have a stress fracture of the shaft of the femur?

If you have or suspect you have a stress fracture of the shaft of the femur, you should stop exercising or participating in sport immediately. Continuing to put stress on the weakened area can worsen the injury, potentially causing the stress fracture to develop into a complete fracture. This not only prolongs recovery but also increases the risk of serious complications. Rest and proper medical assessment are essential to promote healing and prevent further damage.

Could there be any long-term effects from a stress fracture of the shaft of the femur?

A stress fracture of the shaft of the femur does not cause any long-term effects if it is properly treated and the underlying cause of the injury is identified and managed. However, if treatment is inadequate or the cause is not addressed, there is a risk of the fracture worsening—leading to a larger crack, a complete bone fracture, or additional stress fractures when you resume normal activity.
