Anatomical and Biomechanical Analyses of the Unique and Consistent Locations of Sacral Insufficiency Fractures

Abstract

Locations of sacral insufficiency fractures are nearly congruous with stress depicted by walking biomechanical models. Knowledge of stress locations with activities, cortical bone transmission of stress, usual fracture patterns, intensity of sacral stress with different activities, and modifiers of walking mechanics may aid medical management, interventional, or surgical efforts.
