CENTO STEM

The CENTO stem is a modular system designed for hip replacement in particular cases of dysplasia, osteotomies and fractures.

The stem features 3 components: proximal, distal and locking screw.

INDICATIONS

  • Dysplasia;
  • Osteotomy outcomes;
  • Fractures;
  • Femoral canals with distinctive morphologies.

Proximal component

  • Available from size 40 mm to 70 mm;
  • The modular proximal component solves the problems of restoring physiological limb length and the stability of the joint thanks to the four lengths 40, 50, 60 and 70 mm and the two CCD angles of 125° and 135° available;
  • The mirror polishing in the neck area has been designed to eliminate the risk of fatigue cracks;
  • Materials:
    • Titanium alloy Ti 6Al 4V Grade 5 ELI that guarantees excellent biocompatibility and mechanical resistance, the surface finish is obtained by abrasion with corundum granules that increase the contact surface, facilitating the prosthesis-bone anchorage.

Distal Component

  • The distal component is conical with longitudinal fins; this prosthetic design ensures axial stability and resistance to torsional forces at the same time;
  • Modularity is provided by ten diameters (14, 15, 16, 17, 18, 19, 20, 21, 22 and 24*).
