What is a spiral fracture often associated with?

A spiral fracture is typically associated with a sudden rotation of the body while a foot is planted, which can create a twisting motion along the length of the bone. This type of fracture occurs when there is an applied force that causes the bone to twist, which is particularly common in sports or activities where rapid changes in direction are necessary.

The mechanism involves a rotational force exceeding the bone's tensile strength, causing it to break in a helical pattern. This is different from other types of fractures, which may result from impact (like direct blows), continuous strain, or awkward landings. Understanding this mechanism is crucial as it not only aids in diagnosis but also in developing appropriate treatment and rehabilitation strategies tailored to the specific nature of the injury.
