A Femur stress fracture is a hairline fracture of the thigh bone resulting from prolonged overuse. The pain gradually develops as a dull ache and worsens with bending forces applied to the femur.

Symptoms of a Femoral Stress Fracture:
- Dull ache in the thigh area
- Pain when a bending force is applied to the femur (hang test)
- Possible referred pain to the knee
- X-ray may or may not detect the fracture, but a bone scan or MRI provides a more accurate diagnosis
What is a stress fracture of the femur?
The femur, the long bone in the thigh, can develop stress fractures from prolonged overuse, resulting in a condition known as a femoral stress fracture. It can also fracture due to a sudden and forceful impact, similar to other bones in the body.
Treatment:
Recovery necessitates ample rest, notably abstaining from weight-bearing activities. Maintaining fitness through low-impact exercises like swimming or cycling is beneficial. Furthermore, addressing biomechanical issues, such as overpronation, which may have exerted stress on the femur, is crucial.
Healing Time:
The healing time generally spans around 7 weeks, starting from when the hang test shows no pain. Post this period, a phased return to sports-specific training can be initiated.
