Utilizing the Laser Aiming of Image Intensifier Reduces the Exposed Radiation During Operation: A Prospective...

Area of Science:

• Orthopedic Surgery
• Medical Imaging
• Radiation Safety

Background:

• Mobile C-arm units are crucial for real-time intraoperative imaging.
• However, they pose significant ionizing radiation risks to patients and healthcare professionals.

Purpose of the Study:

• To evaluate the efficacy of the laser targeting feature (LTF) in reducing radiation exposure during C-arm fluoroscopy.
• Specifically assessing its benefit in ankle fracture fixation surgeries.

Main Methods:

• A randomized controlled trial was conducted involving patients undergoing ankle fracture surgery.
• Participants were allocated to either the laser targeting feature (LTF) group or a control group.
• Radiation exposure metrics and surgical duration were compared between groups.

Main Results:

• The LTF group required an average of 23 fluoroscopy shots, compared to 38 in the control group.
• Surgical duration was shorter in the LTF group (40 minutes) versus the control group (47 minutes).
• This indicates a reduction in radiation exposure and procedure time with LTF.

Conclusions:

• Integrated laser guidance with image intensifiers can effectively reduce radiation exposure during ankle fracture fixation.
• The LTF shows potential for improving safety in intraoperative imaging procedures.
• Further multi-center validation is recommended to confirm these findings.
