Bone Stress Injury Recovery and Return to Sport: A Natural History Study

Sponsor: HealthPartners Institute

Summary

Lower extremity bone stress injury (BSI) is a common overuse injury in athletes and typically requires 4-12 weeks rehabilitation time, provided the injury does not require surgery. Current BSI treatment strategies include cessation of load-bearing sporting activities, consideration for crutches and/or immobilization, pain management, and a gradual return to activities until symptoms resolve. Premature return to sport can result in risk of complications and reinjury of the healing BSI. Moreover, our prior work reported that 1/3 of women with a tibial BSI will sustain at least one additional BSI within one year, indicating that current return to sport guidelines may be inadequate. However, there are no gold standard or validated clinical, functional or imaging outcomes that are consistently used to assess BSI healing and guide return to sport. In this prospective observational study, the investigators will enroll male and female athletes with a diagnosed BSI. The investigators will utilize diagnostic imaging, blood samples, and questionnaires to identify primary and secondary outcomes for assessing BSI healing in runners. Our long-term goal is to identify whether biomarkers, health and lifestyle factors, and training patterns associated with future BSI have the potential to inform and improve BSI treatment.
