The Trinity Advanced Bearing Acetabular System offers surgeons a wide range of high performance bearings within a versatile acetabular shell, utilizing the clinically proven fixation of BONIT® coating for patient matched solutions. 

• ECiMa (vitamin E) highly cross-linked polyethylene
• Highly cross-linked polyethylene

The BONIT®-coated Hydrolok occluders are pre-assembled within the Trinity shell giving the surgeon two options within one design. This gives the option for three screws to be used for additional fixation. If only one or two screws are utilized, the other screw holes remain occluded, preventing a pathway for fluid between the insert and the acetabular bone.
