Holoma is an innovative mixed reality application that changes orthopedic surgery, enabling surgeons to transfer preoperative programs directly to the operating table and also facilitating the performance of complex surgical procedures. Holoma provides real-time positional guidance and ensures the surgeon will perform the operation exactly as planned, greatly reducing the chances of intraoperative error thanks to unprecedented accuracy and precision of the Holoma's navigation system. Advanced navigation is an intuitive step by step system with checklists, making it easy for surgeons to use even in high-pressure situations, helping to simplify surgery and reduce recovery time later. The navigation flexibility and algorithmic guidance allow performing training simulations as well as supervised practice for students. In a few words, Holoma's accuracy, precision and ease of use make it a valuable tool for surgeons seeking to perform complex orthopedic procedures with minimal errors and maximum efficiency.
