hip replacement:

* Double taper geometry (tulip flare) resists axial and torsional displacement
...The tulip flare of the CORAIL stem fills the femur and resists axial displacement.
...The trapezoidal stem section confers rotational stability (stereostability is the resistance to axial and torsional displacement)

Is axial and torsional displacement "Axial- und Torsionsverschiebung"?
stereostability = Stereostabilität?
resistance to displacement = Widerstand gegen Verschiebung??
