Bone Stress Injuries of the Ankle and Foot An 86-Month Magnetic Resonance Imaging–based Study of Physically Active Young Adults

BackgroundNo comprehensive studies of bone stress injuries in the ankle and foot based on magnetic resonance imaging findings have been published.PurposeUsing magnetic resonance imaging findings to assess incidence, location, and type of bone stress injuries of the ankle and foot in military conscripts with ankle and/or foot pain.Study DesignCase series; Level of evidence, 4.MethodsAll patients with ankle or foot pain, negative findings on plain radiography, and magnetic resonance images obtained of the ankle or foot were included in this 86-month study. Magnetic resonance images with bone stress injury findings were re-evaluated regarding location and injury type. Based on the number of conscripts within the hospital catchment area, the person-based incidence of bone stress injuries was calculated.ResultsOne hundred thirty-one conscripts displayed 378 bone stress injuries in 142 ankles and feet imaged, the incidence being 126 per 100 000 person-years. This incidence represents the stress injuries not dia...
