Brief Summary

Aim: The aim of this cohort study is to precisely measure patients’ exposure to gonadal radiation during orthopaedic trauma surgery involving the acetabulum, pelvis, hip, and femur, and to apply these findings to a previously described and validated formula to determine the increased risk of future adverse health effects to the reproductive organs.15,16

Null Hypothesis:  Standard of care use of x-ray fluoroscopy during treatment of pelvis, hip, and femur fractures will not expose patients to a significant gonadal radiation load.  Analysis of patients’ intraoperative radiation doses by means of a previously validated formula will not display a significantly increased risk of adverse health events in the reproductive organs.15,16



Detailed Description

The use of fluoroscopy during treatment of pelvis, hip, and femur fractures will expose the reproductive organs of patients to a significant radiation load. Analysis of the radiation exposure though radiographic dosimetry and use of a previously described linear no-threshold (LNT) dose-response relationship will display a significant increase in the lifetime risk of fatal cancers and other adverse health events.more than 70% of patients underestimated the radiation dose from procedures during their hospital stay and that the comprehension of increased cancer risk was poor. Additionally, Khan et al showed that only 60% of surgical trainees take into account risks of radiation to a patient. Although some level of radiation is necessary for diagnosis and treatment of these orthopaedic injuries, it has been shown that training on intraoperative technique to keep doses as low as reasonably possible can decrease exposure by more than 50%. We feel that accurate analysis of intraoperative radiation exposure during highly fluoroscopy-dependent cases, such as those involving pelvic, hip and femur fractures, will not only allow the orthopaedic community to better express the risks to the patient, but will heighten awareness of the orthopaedic surgeon performing the procedure. Our hope is that this will support increased training for physicians and support staff on improved fluoroscopy technique.
