The EOSapps are online, 3D surgical planning solutions based on unbiased, weight-bearing EOS images and an accurate 2D/3D patient-specific data set. They fully leverage on the digital data embedded in the 3D model of the patient’s anatomy generated from the low dose EOS images and sterEOS reconstruction. The EOSapps allow implants to be automatically selected and positioned for the best fit based on each patient’s 3D anatomy. They simulate the 3D surgical post-operative results in real-time, including its impact on key clinical parameters of the patient.


Though Total Hip Arthroplasty (THA) surgery is a very common procedure, it remains a challenging surgery. Identifying pre-operative risks and minimizing post-operative complications is crucial for improving results and patient reported outcome measures.

hipEOS 3D surgical simulation and planning software is used to plan primary, total hip arthroplasties. The planning begins with an automatic proposal for the size and position of the stem and cup based on the surgeon’s preferred implants and the patient’s unique anatomy. The patient-specific plan can be adjusted by the physician with immediate feedback on how changes affect relevant clinical parameters.

Thanks to the full body, weight-bearing standing and seated 2D/3D EOS images, hipEOS can be used to anticipate the results of the surgical strategy on implant range of motion (ROM), leg length discrepancies, femoral offset and torsion which are key criteria for successful total hip arthroplasties.

Due to the complex nature of the spine, surgeries may be particularly difficult and call for careful preparation for better outcomes.

The spineEOS online software provides a 3D visualization of the patient’s spine in its current state as well as a literature-based, optimal correction of their anatomy in 3D. The correction can be modified by the surgeon including simulating osteotomies, selecting and positioning cages and accurately planning the length, width and shape of the spinal rods in 3D. All key clinical parameters are displayed in real-time for easier decisions with regards to the surgical strategy.

Thanks to the full body, weight-bearing 2D/3D EOS images, spineEOS displays the anticipated spine after correction and a restoration of a deformative or degenerative spine patient’s global balance pre-operatively.

Due to our aging population, the number of Total Knee Arthroplasties (TKA) has increased drastically during the past decade. Unfortunately, 20% of patients are not satisfied with their surgical results8.

With kneeEOS, you can easily plan your primary total knee arthroplasty by selecting and positioning implants in 3D with immediate feedback on how changes to the plan effect relevant clinical parameters. Thanks to the full body, weight-bearing EOS images, kneeEOS even allows you to anticipate the effects on leg alignment and knee rotation.
