3D planning in orthopedic surgery : precision, customization and security

More precise orthopedic surgery, thanks to 3D technology

What is 3D planning?

There 3D planning in orthopedic surgery is based on the analysis of precise medical images (scanner or MRI) which allow the joint to be virtually reconstructed in three dimensions. This digital reconstruction offers a faithful view of the anatomy, much more detailed than a conventional X-ray.

Thanks to specialized software, the surgeon can:

• Create personalized surgical instruments, such as cutting guides tailored to each patient.

• Accurately visualize the anatomy of the hip or knee.

• Measure the axes, curvatures, wear areas.

• Simulate the intervention upstream (type of implant, size, orientation).

This anticipation makes surgery safer and more effective. The patient benefits from a perfectly adapted surgical procedure, limiting unforeseen events in the operating room.

What surgeries is 3D planning used for?

Dr. Coulin joins the 3D planning in several specific situations where precision is crucial:

• Prosthesis revision : in the event of a worn or poorly positioned implant, 3D planning makes it possible to anticipate the recovery and secure the replacement.

• Total knee prosthesis : it facilitates custom instrumentation and improves alignment, ensuring better implant longevity.

• Complex hip prosthesis or implant revision: virtual reconstruction helps choose the best orientation to regain stability and mobility.

• Corrective osteotomy (genu varum or valgum): 3D planning ensures precise realignment to relieve the joint.

• Reconstruction after trauma or old deformation: 3D modeling allows adaptation to atypical anatomies.

In all these indications, 3D planning improves the reliability and reproducibility of surgical results.

Why does 3D planning improve results?

There 3D planning significantly improves the positioning of the prosthesis by adapting to the actual morphology. It offers:

• Fewer complications : a better positioned implant reduces the risks of misalignment, instability or premature wear.

• Respect for tissues : the incisions are more targeted, preserving the surrounding muscles and tendons as much as possible.

• Accelerated recovery : by anticipating each action, surgery is faster and less invasive.

• Better understanding for the patient : 3D simulation allows you to visualize the intervention and understand the surgical choices, strengthening confidence.

In summary, 3D planning transforms the surgical experience by combining safety, personalization and post-operative comfort.

How does 3D planning work in Geneva with Dr. Coulin ?

In Geneva, Dr. Coulin has implemented a protocol of 3D planning structured, which takes place in several stages:

1. High-resolution CT or MRI to collect accurate images.
2. 3D reconstruction of the joint using dedicated software.
3. Complete simulation of the procedure: choice of size, orientation and axes of the implant.
4. Design of custom surgical guides, if necessary.
5. Surgery assisted according to the approved plan, with rigorous monitoring at each stage.

This secure process improves the reliability of surgical procedures and reduces the time spent in the operating room, while maximizing the accuracy of the result.

3D planning, at the heart of tomorrow's surgery

3D planning is now one of the cornerstones of modern orthopedic surgery. It offers tangible benefits: increased precision, optimized recovery, enhanced confidence, and lasting results.

By combining medical expertise and digital technology, this approach marks a turning point towards more personalized and forward-looking surgery.
