Abstract submitted to Military Health System Symposium 2022

One in every four individuals with an ankle sprain went on to have a proximal joint injury in the following year, knee and lumbar spine diagnoses occurring more frequently than hip. Associated fracture with the initial ankle sprain increased the odds of sustaining a subsequent hip or lumbar spine injury. Further, females had higher risk of developing subsequent hip or lumbar spine injuries after ankle sprain whereas males were more likely to develop subsequent knee issues. Less than half of the cohort received rehabilitation following an ankle sprain, but exercise therapy was found to be preventative of secondary injuries to the knee, hip, and lumbar spine. While these associations are often discussed by clinicians, the increased understanding of prevalence of proximal joint disorders has the potential to help guide treatment and inform decisions related to returning to work and sport, improving the care for patients and decreasing the physical and financial toll of this common injury.
