In orthopedic surgery, preoperative planning is an essential step and an effective way for surgeons to anticipate potential surgical challenges and begin targeting the choice of implants. However, in order to ensure the best possible solution, they must take into account numerous criteria, including the patient’s clinical presentation, type of procedure, choice of prosthesis model, and prosthesis placement…
In many cases, the specific anatomical characteristics of patients require them to order multiple prostheses to ensure they have the appropriate materials during the operation. However, this operating method poses several problems:
- It requires immobilizing material resources that the surgeon will not use and could be used for other purposes.
- This procedure requires sterilization of all components before and after surgery, even for unused pieces, which mobilizes medical teams and creates avoidable workload burden.
- Multiple sizes of prostheses are tested during the surgical procedure, which prolongs the surgical time.
- The surgeon must spend a considerable amount of time analyzing the most optimal way to position the prosthesis to ensure proper functioning of the limbs together.
How can we limit costs and optimize the management of medical resources? How can we ensure that the surgical technique and implant are as effective as possible?
Provided solution
We have developed a 3D reconstruction and anatomical landmark detection software for ankles, hips, and knees. This solution allows surgeons to precisely visualize the patient’s anatomy preoperatively in order to establish the necessary surgical procedures.

Solution development
Neovision has developed a solution that enables 3D reconstruction of the bones of the lower limb and anatomical landmark detection. We have leveraged a deep learning algorithm and standard DICOM medical imaging data (a series of stacked 2D cross-sectional images that create a volume).
3D Reconstruction
This functionality automates the task of manual reconstruction performed by medical specialists by utilizing an algorithm instead. This automated process addresses a 3D segmentation challenge, precisely obtaining the bones of the lower limb (pelvis, femur, tibia), especially the joint areas that are complex and crucial for surgeons. To accomplish this, we transformed the DICOM data into Nifti format, which is suitable for deep learning tasks in 3D. The segmentation representation is a point cloud that describes the bone surface and defines the contours of each bone.
Landmarking
Neovision has developed a landmarking algorithm, which involves the identification of strategic anatomical points for each bone (such as the tibial plateau, talar dome in the case of the ankle, for example). To achieve this, we relied on the knowledge of orthopedic surgeons to create a database of anatomical points that are essential for successful surgery.
The combination of these two approaches enables surgeons to assess, prior to the operation, what the most optimal surgical decision will be. This includes selecting the appropriate prosthesis, determining its positioning, and planning the bone cuts

Client testimonial
We had the pleasure of collaborating with Neovision on the development of an AI solution dedicated to medical imaging, enabling 3D reconstruction and anatomical annotation for the automatic 3D planning of implants in orthopedic surgery. Although the project took longer than initially expected, we would like to highlight the exceptional quality of the work delivered. The Neovision team, as well as its management, demonstrated exemplary professionalism, great availability, and attentive listening throughout the entire process. Their ability to adapt to our needs, together with a comprehensive knowledge transfer process, ensured a smooth transition and enabled our teams to fully adopt and take ownership of the solution. We are extremely satisfied with the final result and with Neovision’s commitment throughout this collaboration. Thanks to their expertise in AI and medical image processing, we now have a powerful tool that will significantly improve our surgical planning process. We can wholeheartedly recommend Neovision for innovation projects requiring expertise in artificial intelligence.
