The scope of Total Hip Arthroplasty (THA) has expanded considerably in recent years to include younger, more active patients. The surgical objectives have evolved from merely relieving pain to restoring full function.7
hipEOS is used to plan a primary, total hip arthroplasties starting with an optional plan that includes the selection and position of the two implant components in 3D based on the patient’s anatomy. The plan can be adjusted by the physician with immediate feedback on how changes affect relevant clinical parameters.
Thanks to the full body, weight-bearing 2D/3D EOS images, hipEOS can be used to anticipate the consequences of the surgical strategy on leg length discrepancies, femoral offset and femoral torsion; three key criteria for successful total hip arthroplasties.
- Patient-matched implant size selection5without complex radiological calibration protocols
- Patient-specific, 3D planning for cup inclination/anteversion, stem torsion and localization of the femoral neck resection plane, without the need for additional CT exams
- Real-time, 3D simulation of the restoration: automatic calculation and display of key clinical parameters including lower limb discrepancy and femoral offset variation
- Automatic proposal of implant size and position according to the 2D/3D patient data set
- Online database of 3D templates from multiple implant manufacturers
- Online access from any computer through a compliant server
- Customizable, patient-specific planning reports
