Abstract: Background: The purpose of this study was to determine risk of shoulder injury in astronauts returning from space flight and highlight the need for further exploration of risk factors and preventative strategies. Methods: Using The Lifetime Surveillance of Astronaut Health epidemiology database at National Aeronautics and Space Administration, a retrospective cohort study was conducted to assess the effect of space flight mission duration on rate of shoulder injury among astronauts. Inclusion criteria were all astronauts who participated in space flight regardless of age or space flight mission time. Exclusion criteria were all injuries occurring greater than 5 years following return to Earth. Patient demographics were compared between injured and noninjured cohorts with stratification by shoulder pathology. Results: < .001). Conclusion: Space flight missions greater than 6 months were associated with increased risk of shoulder injury, especially rotator cuff tears. However, specific aspects of space flight that increase risk remain understudied. Shoulder injuries upon return to gravitational environments have the potential to negatively impact astronaut health and possibly jeopardize mission success, particularly as upper-extremity mobility is vital in the microgravity environment of space.
