S-TAPER SYSTEM

Features:

• A conical shape in the antero-posterior and lateral plane so as to ensure an anchor not only in the proximal or distal part of the femur but over the entire portion of the prosthesis socket.
• Gradual sizing of the entire prosthesis. As the size increases, the neck, width and thickness increase proportionally.
• Distal end of the prosthesis rounded to enable easy insertion.
• 2 holes for removal, one threaded axially at the apex of the stem and one in the antero-posterior.
• The “S-TAPER” stem allows the joint biomechanics to be respected: CCD angle 131° and 123°.

Materials

In order to increase osseointegration without the use of additional porous coatings, the S-TAPER stem is finished using an extremely rugous corundation, ensuring Ra5-7 μ.

S-TAPER ODEP RATING : 3A

The long version was created because of surgeons’ current need for an alternative system to the means of fixation (nail or screw-plate) in lateral fractures of the femur in elderly patients.

Wedges are added to the stem to restore the proper biomechanics of the hip.

• 3 sizes in fixed lengths of 170 mm and 190 mm.
• Possibility of slide insertion of wedges with accommodation on the calcar for lateral femoral neck fractures.
• 8 wedge sizes with heights of 0, 5, 10, 15, 20, 25, 30, 40 mm.

Materials

High-nitrogen stainless steel (ISO 5832/9).
