cementless femoral stem cementless femoral stem - S-Taper


  • Fixture type:



Uncemented straight stem

– Conical shape in the antero-posterior and lateral planes, ensuring anchorage not only in the proximal or distal part of the femur but on the entire portion of the prosthesis housing
– Graded sizing of the entire prosthesis; width and thickness increase in proportion to the size of the neck
– Rounded distal extremity of the prosthesis is to facilitate insertion
– Two holes for removal, one threaded axial at the top of the stem and one in an antero-posterior position, thus providing two possible ways to remove the stem if necessary
– Compatibility with the biomechanics of the articulation (CCD 131°and 123°)
– Compliance with European Standards, with a standard 12/14 morse taper (5°42’30’’) with CERAMTEC approval


-The prosthesis is made of titanium with a low elasticity modulus TI 6Al 7Nb (ISO 5832-11) which can tolerate temporary deformation under stress. It encourages balanced load distribution over all the surrounding areas. No concentrated forces are applied to any particular area or element, as in a healthy, unbroken femur
-To increase osteo-integration without the use of additional porous coatings, the “S-TAPER” is given an extremely rough corundum finishing guaranteeing an Ra of 5-7 μ
