Summary

A laser aiming guide did not reduce radiation exposure for orthopaedic surgeons during intraoperative fluoroscopy. The device showed no significant benefit in lowering radiation exposure time or number of exposures in most cases.

Area of Science:

  • Orthopaedic Surgery
  • Occupational Health
  • Medical Physics

Background:

  • Intraoperative fluoroscopy exposes orthopaedic surgeons to ionizing radiation, posing significant occupational health risks.
  • Long-term radiation exposure can lead to eye damage, increased cancer risk, and other serious health issues.
  • The study investigated the efficacy of a laser aiming guide in mitigating this radiation exposure.

Purpose of the Study:

  • To evaluate the impact of an attachable laser aiming guide on radiation exposure during intraoperative fluoroscopy in orthopaedic procedures.
  • To determine if the laser aiming guide effectively reduces radiation exposure time and/or the number of exposures for surgeons.

Main Methods:

  • A prospective, randomized controlled trial involving 880 orthopaedic procedures.

  • Procedures were divided into two groups: fluoroscopy with and without a laser aiming guide.
  • Data collected included total exposure time, number of exposures, and body region examined.

    • Main Results:

    • No significant difference in exposure time or number of exposures was observed for most anatomical regions.
    • For hip fractures, the laser aiming guide was linked to an increased number of exposures, but not exposure time.
    • Wrist examinations showed an increase in both the number of exposures and exposure time with the aiming device, potentially due to selection bias.

    Conclusions:

    • The use of a laser aiming device during intraoperative fluoroscopy was not found to decrease radiation exposure for orthopaedic surgeons.
    • The findings suggest that laser aiming guides may not be an effective tool for reducing occupational radiation risks in this setting.
