Visualising the Future of Orthopaedic Surgery: A Novel Application of Wireless Smart Glasses to Visualise Intraoperative Imaging

Smart glasses can provide a heads-up display of advanced imaging intraoperatively. In recent years, growing attention has been drawn to the use of smart glasses as an assistive technology to improve both efficiency and ergonomics in a surgical setting. Previous studies have reported improved surgical accuracy, efficiency, and ergonomics with its usage, but its effectiveness as a form of intraoperative heads-up display remains elusive in the context of orthopaedics. This study provides a novel account of a wireless set-up of the Moverio BT-35E Smart Glasses (Suwa, Japan: Epson Inc.), incorporated in a complex orthopaedic procedure. Hind-foot nailing was performed on a patient with a complex open ankle fracture and multiple co-morbidities. Smart glasses were worn by the primary surgeon throughout the procedure to provide heads-up visualisation of the intraoperative fluoroscopy. In our surgical case, the surgeon experienced improved ergonomics and reduced disruption to focus with the use of smart glasses. The wireless set-up provided excellent signal transmission throughout the duration of the procedure. The wireless set-up of smart glasses is a potential solution for common occupational risks imposed on orthopaedic surgeons. Smart glasses minimise musculoskeletal strain from switching of vision from monitor to patient, whilst the wireless set-up allows for efficient use of space in an operating theatre and may potentially limit radiation exposure. Lastly, ergonomic benefits may increase the efficiency of movement for the surgeon, decreasing operative duration, and in turn minimising the risk of surgical complications for patients.
