Description
This presentation from the ISTA 2024 conferenced held in Nashville, discusses the advancements in mixed reality (MR) and its applications in surgical procedures, particularly focusing on patient-specific implementation during total hip arthroplasty. Mixed reality is defined as the integration of virtual content with the real-world view of a user. The technology allows surgeons to project personalized three-dimensional patient data onto the surgical field, aiding in surgical planning and execution with what the presenter describes as 'X-ray vision.'
The workflow begins with preoperative planning using CT scans to create a detailed 3D model of the patient, which includes key measurements to determine component size and orientation needed for surgery. Surgeons can use this model to plan the optimal positioning of implants and account for anatomical variations, ensuring better alignment and stability. During surgery, a head-mounted display is utilized to overlay holograms that represent the planned surgical steps, such as reaming, cup placement, and screw trajectories. This is achieved through a tracking system that compensates for patient movement, ensuring accuracy throughout the procedure.
The presenter shares clinical accuracy data demonstrating that using mixed reality guidance results in significantly lower errors in surgical alignment compared to traditional methods. They highlight the efficiency, intuitive use, and overall improved outcomes that this technology offers in complex hip surgeries. The enthusiasm for future advancements is evident, as the presenter mentions the FDA clearance for the technology and hints at the potential for integrating further imaging capabilities, like intraoperative fluoroscopy. In conclusion, mixed reality is portrayed as a revolutionary tool that enhances surgical precision and represents a significant advancement in medical practice.
