13:00-14:00 Session 1A: Workshop 1: MDR: Patient specific protheses, plans and workflows, managing conformity under MDR

Custom patient-specific implants and workflows allow for more flexibility in treating patients. However, can any clinical center currently make and place custom implants while there are strict guidelines for production and follow-up of standard prosthesis. How do we navigating European legislation in custom implants: design, production and use?

13:00-14:00 Session 1B: Workshop 2 (1 of 2): CAS: Hands-on Digital Planning and Execution using the Brainlab CAS System: Image-based for Trauma, Spine, Oncology or Complex Orthopedics

Learn hands-on case-based planning. Import custom designs from medCAD software like 3matic. Integrate this in Origin, the Brainlab planning platform. Perform multiple surgeries: spine, trauma, complex orthopedics and oncology on 3D printed cases. This workshop is come and go, join us for 1 case or multiple.
