Abstract
We review the spectrum of acute osseous injuries in athletes, ranging from osseous
contusion (bone bruise) injuries to nondisplaced cortical fractures. The basic biomechanical
concepts, underlying histopathologic changes, and characteristic magnetic resonance
imaging (MRI) features of acute osseous injuries are presented. Bone bruise injuries
of varying severity are highlighted to showcase the breadth of imaging findings on
MRI and methods for characterizing such lesions. We emphasize the importance of accurately
assessing patterns of injury on MRI to communicate more effectively with team medical
staff and recognize the implications on return to play. This article offers the foundational
tools for approaching bone bruise injuries in elite athletes to add value to the diagnosis
and treatment of this unique patient population.
