Abstract: Background Eversion ankle sprains, although less common than inversion injuries, are often associated with greater severity and more complex recovery patterns. Their biomechanical origin remains less clearly understood. Objective To propose a functional, longitudinal kinetic chain model in which anterior innominate rotation (AS) may contribute to the development of eversion ankle sprain injuries. Methods This hypothesis-driven model is based on clinical observation and biomechanical reasoning. Anterior innominate rotation may lead to pelvic asymmetry, a functional long-leg pattern, internal femoral rotation, and toe-in mechanics. Results (Hypothesis) These adaptations may increase medial loading, promote collapse of the medial longitudinal arch, and alter ground reaction forces. This may compromise medial stability and reduce the capacity to control eversion forces, increasing susceptibility to injury. Conclusion Eversion ankle sprains may represent the distal expression of proximal biomechanical dysfunction. Recognition of anterior innominate rotation may improve injury prevention strategies.
