The main objective of orthoMIT is to develop an integrated platform for smart therapy in orthopedic surgery and traumatology. Flexible modules for hip, knee and spine surgery enable an individual therapeutical procedure. The following results and innovations were achieved up to now during the first term of the project:
Smart Intraoperative Imaging
Outstanding innovative concepts of intraoperative 2D- und 3Dimaging have been developed, which have special impact on interventions of spine surgery and traumatology:
- New methods of dose calculation for C-arm based cone beam CT enabling an optimized radiation protection (Monte Carlo simulation tool ImpactMC).
- Zero-Dose-C-Arm-Navigation for radiation free optimal positioning of the C-arm by virtual previews.
- Robotic C-arm x-ray imaging for intuitive navigation of the Carm and new scan strategies as well as imaging options.
- 3D-ultrasound imaging and referencing MR-data to complete and update the intra-operatively available information of morphology and function.
Smart Knee and Hip Surgery
Innovative highlights were especially developed for minimally invasive knee and hip surgery without x-ray imaging:
- Marker- and trackingless total knee arthroplasty based on miniaturized instrumented force-torque sensors and inlays (genALIGN, patent pending).
- Ultrasound based identification of landmarks for individualised biomechanical planning models (hip replacement, repositioning osteotomies).
- Identification und 3D-reconstruction of femoral bone cement based on a miniaturised ultrasound scanner including modules for navigated and optional robotic removal of cement (hip revision surgery).
- Modular sterilizable 5DOF minirobot for minimally invasive hip revision surgery, knee replacement und endoscopic spinesurgery.
- A magnetic tracking system, robust against interfering field: by miniaturised markers and compensation of low frequent interferences of magnetic field (patent pending).
- Spherical repositioning osteotomy for repositioning of the acetabulum in case of hip dysplasia with minimally invasive fixation, optimal repositioning und mobility.
An innovative concept for modular integration of different applications und components in an integrated surgical workstation including user interfaces has been developed:
- Architecture for integration and security based on a Service-Oriented Architecture (SOA). The orthoMIT-concept is explicitly named as an example in the international standard IEC 80001.
- Smart OR-table for a knowledge based anthropometric OR-table positioning reducing non-ergonomic working postures.
- Innovative concept for user interfaces, e.g. Remote Pointer (patent pending) for sterilizable intuitive interaction with the integrated workstation.
