Every patient is unique

Femoral morphology varies greatly from one person to another in the three dimensions of space. Research conducted by Husmann and Sariali has demonstrated these variations in the proximal femur and hip in 3D, even in cases often considered “normal”. In some rarer cases, the hip anatomy can be dysplastic and deviate greatly from the anatomical averages for which standard hip prostheses were designed.

No-compromise femur reproduction

Each individual is different, so the INDIVIDUAL HIP® stem is designed to adapt perfectly to the shape of the medullary canal in all three dimensions, so no need for compromise:

• Supports designed to adapt most effectively to the mediolateral flare of the intramedullary canal;
• Anatomic sagittal curvature reproducing the anterior curvature of the patient’s femur;
• Restoration of the natural torsion of the femur on the axial plane.

Restored femoral anteversion

The stem is designed to restore femoral anteversion in a personalised manner and to maximise anterior-posterior stability and joint function.

• Restoration of native anteversion or correction of anteversion according to the planning agreed between the surgeon and the Symbios engineer;
• Consideration of the patient’s step angle, allowing the lower limb to function efficiently.

A multitude of options

In addition to adapting to the patient, the individualized stem adapts to the standard practices of each surgeon, with a multitude of options and variants:

Cementless individualized stem

• Optional full or partial stem coating;
• Optional collar.

Individualized cemented stem

• Recommended when the primary stability criteria for a cementless option are not met;
• Optional collar.

Individualized smooth compactor

• For optimal compaction of the spongious bone.

Individualized pricked rasp

• To make working with very dense bone easier.
