A New Method for Reducing Radiation Exposure in the Operating Room is the Use of Computer Numerical Control Plotter

Research Type: Level 1 - Randomized controlled trial (RCT), Meta-analysis of randomized trials with homogeneous results Introduction/Purpose: Every orthopedic surgeon is aware that radiation exposure in the operating room poses a risk to their profession. Our goal is to minimize to ALARA (As Low As Reasonably Achievable) radiation exposure. Numerous methods have been attempted to lower radiation, but none have proven effective. The role of the CNC plotter – a novel idea is evaluated Methods: Included were the radiation-exposed orthopedic procedures carried out from 2020 to 2022. Following informed consent and ethical approval, radiation-exposure was compared with and without the use of the CNC Plotter technology: A 42-inch TV monitor was linked to the operational field's dome and side cameras, which provided live orthopedic field footage (two in one view). The camera's magnification were precisely matched to the real-time reference marker. Preoperative X-ray outlines were drawn on a clear sheet using a CNC plotter that was accurate to the scale of the PACS dimensions of the bone (completed prior to surgery using a PACS X-ray). Double-sided tape was used to adhere this sheet to the TV monitor. As directed by the Surgeon from later C-arm images, this clear sheet was utilized to mark a spot or draw a trajectory (using a temporary marker by the C-arm operator). The sheet could be cleaned and redrawn Results: Using a real-time monitor, an accurate X-ray plan was created as an outline on a clear sheet. The surgeon operated with ease - surgical precision increased upto 100% while radiation exposure decreased by up to 42% Conclusion: With enormous potential, using a CNC plotter is an innovative way to reduce radiation exposure in the operating field. Future considerations could include Artificial Intelligence and Machine Learning CNC Plotter
