Trinity
Advanced Bearing Acetabular System
Patient demographics have changed over time(1) and today’s patients have both an increased expectation of post-operative functional outcome and the need for a more durable, long lasting implant solution. All patients expect optimised function of their joints to suit their lifestyles and true intra-operative versatility is an essential requirement of any modern day acetabular cup system. In addition to durability and a low wear solution, both stability and a high range of motion are essential in optimising function and quality of life for today’s more demanding patient population.
Design
The Trinity Advanced Bearing Acetabular System offers surgeons a wide range of high performance bearing solutions within a versatile system:
- BIOLOX delta ceramic-on-ceramic
- Optimom metal-on-metal
- ECIMA (vitamin E) highly cross-linked polyethylene
The Trinity two-in-one shell allows all three bearings used in one design that seamlessly integrates the maximum articulation size. The ceramic and metal inserts lock securely onto the taper providing high axial resistance. The 18° taper is designed for optimal security and ease of insertion without mis-alignment. The polyethylene insert also locks into the castellations which provide high torsional resistance to rotation.
- Trinity hemispherical titanium shell is designed for excellent initial press-fit and long-term stability
- Vacuum plasma pure titanium and BONIT coating for clinically proven long-term fixation(2,3)
- Highly polished Prime rim to prevent irritation and impingement of the psoas
- BONIT-coated Hydrolok occluders fill the screw holes minimising fluid pathways
- Screws can be used by removing Hydrolok occluders for versatile fixation
- Thirteen shell sizes for patient matched solutions
Performance
The Trinity system is designed to allow maximum bone preservation without compromising range of motion or stability. The system includes 13 shell sizes from 44 to 68mm and provides a full range of bearing sizes from 28mm through to 40mm in all high performance bearing options.
- 28mm bearing in a 44mm and 46mm shell
- 32mm bearing in a 48mm and 50mm shell
- 36mm bearing in a 52mm and 54mm shell
- 40mm bearing in a 56mm and 58mm shell
- 40mm bearing in 60, 62, 64, 66 and 68mm shell
The BIOLOX delta ceramic-on-ceramic, Optimom metal-on-metal and ECIMA (vitamin E) highly cross-linked polyethylene bearings all follow this size range philosophy, allowing the surgeon to deliver a patient matched solution.
