Connexion GXL® Polyethylene

Connexion GXL® enhanced polyethylene acetabular liners provide a low wear rate while maintaining an appropriate level of fracture toughness.
 

 
Hip simulator studies show a 59 percent reduction with Connexion GXL over Exactech standard material in wear rate with sterilization dose.^1,2,3,4

 


Fracture toughness results: Compression-molded Connexion GXL exceeds the minimum acceptable "J-integral".
