Karey Primary Stems

A complete system designed to facilitate the surgeon’s
mission of restoring the patient’s original anatomy.

· 12/14 Neck Taper:
Compatible with Surgival CrCo and Ceramic femoral heads.

·Triple Taper Design:
The trapezoidal shape in the sagittal and frontal planes offers greater primary stability and prevents prosthetic subsidence. The distal part is progressively subdimensioned to reduce the rigidity of the implant and to improve the contact with the cancellous bone (secondary stability).

· Metaphyseal semicircular macro-structures:
Increase the contact surface, avoid component subsidence and have antivaro effect.

· HA Coat:
130 micron HA Coating by Air Plasma Spraying.

· Longitudinal Grooves:
Increase the bone-implant contact surface, prevent rotation, decrease distal tightness with respect to the metaphyseal portion and improve the diaphyseal vascularization of the prosthetic femur.
