aSphere Contoured Metal Heads - Design Rationale

Precision contoured aSphere™ M-Spec heads approximate the shaping that occurs during the in vivo run-in wear phase. This advanced design incorporates a wear-resistance zone, so patients may experience a substantial decrease in metal wear debris and ion release when compared to conventional designs. Combined with DePuy TrueGlide™ technology, the aSphere M-Spec head helps facilitate a more fluid range of natural motion for patients.
