Stress fractures are primarily caused by what type of force?

• A. Shear stress from lateral impact
• B. Extremely high forces from accidents
• C. Unusual or repetitive forces
• D. Direct trauma from falling objects

Answer: (C)

Stress fractures are primarily caused by unusual or repetitive forces acting on the bones. These types of fractures occur when the body is subjected to repeated stress, such as from activities like running, jumping, or any repetitive motion that places strain on the skeletal system. Over time, these moderate forces can lead to small cracks in the bone without a single, acute traumatic event. This condition can often affect athletes who may increase the intensity or frequency of their training without proper conditioning or rest. The cumulative effect of the repeated forces can exceed the bone's ability to adapt, resulting in a stress fracture. Awareness of this cause is essential for prevention, as it can guide training regimens and emphasize the importance of adequate recovery time to allow the bones to heal and strengthen.
