Proven Features

29% Lower Risk of Revision1

The CORAIL® Standard Collared femoral stem has been shown to have a 29% lower risk of revision when compared to all other cementless stems on the NJR.

Significantly Reduced Risk of Periprosthetic Fracture1

Periprosthetic Fracture is one of the leading causes of revision for THR in the NJR2 The CORAIL Standard Collared femoral stem has been shown to have significantly lower than expected rates of revision due to periprosthetic fracture when compared to all other cementless stems on the NJR.1

123,536 Primary Implantations3

According to NJR data from 2003 to 2017 123,536 CORAIL® PINNACLE® Cementless implantations were used in primary THR and compared to all other cementless constructs in NJR. Hazard ratio adjusted for age, gender, year cohort and indications.
