A CoCr modular neck provides for a strong neck construct. Fatigue testing has shown that the SMF Cobalt Chrome modular neck design exceeds the fatigue strength of the same neck design made out of titanium alloy by as much as 83% and a conventional titanium monolithic hip stem by as much as 18%.1
Utilizing radiosterometric analysis (RSA), the SMF system demonstrated stability consistent with the clincially successful SYNERGY* primary hip stem. Moreover, HHS and WOMAC scores indicated excellent relative clinical outcomes for the SMF group.2
With one of the highest coefficients of friction in the industry3, a porosity of 60% and an average pore size which is ideal for boney ingrowth4, Stiktite* coating provides a solid foundation for both initial and long term fixation.
