Virtual reality (VR) technology has rapidly evolved from a novel concept to a transformative tool in orthopedic surgery, particularly in pre-operative planning. By enabling immersive, three-dimensional visualization of patient-specific anatomy, VR offers surgeons unprecedented precision and insight before entering the operating room. This advancement is reshaping surgical workflows, enhancing decision-makingand ultimately improving patient outcomes. In the context of modern orthopedic practice, where complex anatomical variations and intricate procedures are commonplace, VR-driven pre-operative planning stands out as a critical innovation that addresses longstanding challenges in surgical preparation and execution.
The integration of VR into pre-operative planning allows surgeons to interact with detailed, manipulable models derived from high-resolution imaging modalities such as CT and MRI scans. This immersive environment facilitates comprehensive assessment of fracture patterns, deformitiesand spatial relationships between anatomical structures. Consequently, surgeons can simulate surgical approaches, optimize implant positioningand anticipate potential complications with greater confidence. The result is a paradigm shift from traditional two-dimensional planning to a dynamic, interactive process that enhances surgical precision and reduces intraoperative uncertainty.
