In which direction does a stress fracture typically occur?

A stress fracture typically occurs along the length of the bone due to repetitive stress or overuse. This type of fracture is a result of micro-damage that accumulates in the bone tissue, often from activities such as running, jumping, or other high-impact sports. As the bone is subjected to repetitive loading, microscopic cracks develop, primarily oriented along the long axis of the bone.

This directional pattern is critical for understanding the mechanics of stress fractures and the types of forces that can lead to them. Proper identification and management of stress fractures are essential in preventing further injury and in guiding rehabilitation protocols.
