What is the most common site for stress fractures?

Stress fractures are typically the result of repetitive stress or overuse, and they are most commonly found in the lower extremities. In particular, the metatarsals of the foot are a frequent site for these injuries due to the weight-bearing activities that place significant strain on these bones. The repetitive impact from activities like running or jumping can lead to micro-damage in the bone structure, resulting in a stress fracture.

While other areas, such as the spine and pelvis, can also be affected by stress fractures, they are far less common than those in the foot. The upper extremities are generally less prone to stress fractures due to the different mechanics of force distribution during physical activity. The prevalence of stress fractures in the metatarsals underscores the importance of proper training and awareness of symptoms in athletes and active individuals.
