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

Abstract

Mobile C-arm units provide real-time intraoperative imaging but expose both patients and staff to ionizing radiation. This study aims to reveal if the use of the laser targeting feature of image intensifiers (available in most of the latest series) is beneficial for preventing radiation exposure.

A randomized controlled trial was designed on the ankle fracture operations. Patients were randomly assigned to either the laser-targeting feature (LTF) group or the control group.

The study group has an average age of 40.8 years, ranging from 16 to 71; 23 were men and 27 women. The control group has an average age of 32.8 years, ranging from 16 to 78; 21 were women and 29 men. An average of 23 (20-30) fluoroscopy shots were taken during surgery in the study group. In contrast, an average of 38 (34-48) fluoroscopy shots were taken during surgery in the control group. The duration of surgery in the study group was 40 minutes (36-55 mins), whereas in the control group, it was 47 minutes (40-65 mins).

These findings suggest that integrated laser guidance may reduce radiation exposure during ankle fracture fixation surgery; however, multi-centre validation is warranted.
