How long does the planning take?
The learning curve is steadily increasing as you work with the software on a regular basis. At the beginning a planning can take 20 min but with time this can be reduced to 5 min.
Do the images for 3D planning also have to be taken with a scaling sphere?
No, with the known slice thickness and the grid, it is no longer necessary to scale using a reference sphere for CT/MRI. Absolutely precise planning is possible.
Which image data can be loaded into mediCAD 3D?
CT, MRI, DVT, X-ray images, but also PNG and JPEG.
Can you plan on MRI data?
Yes, with mediCAD 3D it is possible to plan on MRI images.
How do I get the images from the PAC system into the software?
We have the possibility to connect all 3D modules with our QueryClient to any PACS in the world. This means that you can load the CT images directly into the software and save them audit-proof in the PACS after planning.
How to plan for an admission with an inserted prosthesis?
When planning a revision, the radiation artefacts caused by the inserted implant can be reduced in the programme and the inserted implant can be hidden.
In the case of an inserted prosthesis, can I check in the event of a revision whether the implant has been correctly installed mechanically?
Yes, you can measure the implant and thus assess the rotational alignment, for example.
Is 3D printing possible?
Yes, with the software you can segment different body regions, using the “Segmentation” function and save them as an STL. file. The STL. file can be printed with a 3D printer.
What other advantages does 3D planning have?
You may be able to simplify logistics through precise sizing and also reduce your sterilisation costs.
Is it possible to transfer the 3D spine planning to a navigation device?
Unfortunately, this is not possible at the moment. However, a solution is being worked on.
3D Knee - What imaging is necessary or possible for knee 3D planning?
You can use both a CT and an MRI. In addition, you can also combine both “hybrid” with an X-ray. Likewise, you can work with a DVT image (digital volume tomography).
3D Knee - Can osteotomies also be planned in the 3D knee module?
Yes, you can plan both open wedge and closed wedge as well as transversal (rotation correction) osteotomies 3-dimensionally and automatically receive the size of the wedge calculated as well as a calculation of all relevant values after a correction.
3D Knee - Can I also calculate torsions in mediCAD Knee 3D?
Yes, in mediCAD Knee 3D both femoral torsion (according to Weidelich) and tibial torsion (according to Jendt) can be calculated.
3D Knee - Is it always necessary to take a whole-leg CT scan to measure the leg axes?
No, 3 partial scans of the pelvis, knee and ankle are sufficient. It can also be planned in “hybrid” mode. In this case, a CT scan of the knee joint is sufficient and the leg axes are measured on the whole leg X-ray.
3D Knee - How can I reduce radiation exposure during CT and still plan accurately enough?
You can take the 3 partial scans of the hip, knee and ankle with different slice thicknesses. These are precisely merged in mediCAD Knee3D.
The higher slice thickness when taking the pelvic overview and the ankle joint reduces the radiation exposure. Furthermore, planning is possible with an MR image or hybrid with a combination of or DVT together with a whole leg X-ray in order to reduce the radiation exposure even further.
3D Knee - How accurate is the size planning of the prostheses?
The size planning of the prostheses is extremely accurate, as you can precisely assess the coverage of the tibial component on the plateau in the axial view and also plan the size of the femoral component and whether the design fits the patient’s physiognomy in the best possible way axially. Furthermore, when planning the tibial component in the 3D model, the femur can be completely hidden, just as the tibia can be hidden when planning the femoral component.
3D Knee - Can the rotation of the femoral component be planned sensibly?
You can measure the rotation angle of the component in relation to the transcondylar axis or in relation to the posterior condylar tangent.
3D Shoulder - What are the image requirements?
3D Shoulder - Do you have inverse implants in the database?
The implant database of the 3D Shoulder software includes both anatomical and inverse implants. In addition, modular and fructure systems are also available.
3D Shoulder - Is PSI possible?
No! In the software you have a visual guide for the placement of the K-wire. Once you plan the glenoid component, an implant coverage appears in the software on the right side. The illustration gives you the information in which area you position the K-wire and the setting of the version and inclination, can be found below with the implants.
