VANOLI, Fernando et al. Exposición a la radiación de los cirujanos en la fijación interna de fracturas de radio distal. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2017, vol.82, n.4, pp.271-277. ISSN 1852-7434.

Introduction: The objective of this study is to provide reference values of radiation doses absorbed by surgeons during open reduction and internal fixation of distal radius fractures. Methods: We prospectively evaluated radiation exposure during surgery for distal radius fracture between May and December 2015. Exposure was evaluated in two surgeons using dosimeters in thorax, neck, and wrist. A relative radiation index for each surgery was calculated to identify the differences among sites and to establish reference values for radiation monitoring. Results: Results of surgery performed in 50 patients were evaluated. Surgical procedure averaged 40 minutes (SD 2.06), and there were no statistically significant differences between both surgeons (p=0.043). C-arm exposure time averaged 75 seconds. There were significant differences between surgeons (p=0.007) or among sites (p<0.05). Radiation in the thorax was smaller (protected with a lead vest, 0.04 mSv) than in the other two sites (not protected with lead): wrist 0.017 mSv and thyroid 0.18 mSv. Conclusions: During open reduction and internal fixation of distal radius fractures, surgeons are exposed to direct radiation during fluoroscopy, which varies according to the exposure site and it is not uniform among surgeons. The amount of radiation received by surgeons, when only distal radius fractures are considered, cannot be associated with increased risk of cancer or malignancy development.
