Which type of fracture is often seen as a result of torsion or twisting motion?

A spiral fracture occurs when a bone is subjected to a twisting or torsion force, leading to a fracture that spirals around the bone rather than breaking straight across. This specific type of fracture is characterized by its helical shape, which reflects the way the applied force has caused the bone fibers to separate in a twisting motion.

Understanding the mechanics behind a spiral fracture is crucial for both diagnosis and treatment in athletic training. It indicates not only the direction and nature of the injury but also the possible need for specific interventions, such as surgical correction or immobilization strategies. This type of fracture is distinct from other types, such as serrated, longitudinal, and oblique fractures, which have different causes and implications in terms of healing and rehabilitation.
