Tri-Por®

Tri-Por®

Adler Ortho® employs the Powder Manufacturing Technology to work with thre three metal alloys more commonly used in Oerthopaedics: Titanium Alloy, Cobalt-Chrome alloy, and Stainless Steel. The Tri-Por® logo identifies all the implants made by Adler Ortho® employing this innovative technology.

Titanium alloy

The Ti-Por® 3D monolithic ingrowth surface repèresents one of the main achievements of Adler Ortho® research in the Powder Manufacturing field.

The Ti-Por® is extremely rough, and therefore it can supply implants with a much higher primary stability Vs the one provided by standard technologies. Therefore the Ti-Por® surface, being built in one piece together with the implant has a resistance to delamination that cannot be matched by any porous coating or plasma spray normally employed for cementless orthopaedic implants.

CoCrMo alloy

This alloy, because of its hardness and wear resistance, it is commonly used to manufacture mobile articular surfaces, especially, but not only, for knee implants applications.

Adler Ortho® employs the Powder Manufacturing Technology also to produce CoCrMo alloy made implants. Those implants feature the Co-Por®, 3D monolithic ingrowth surface, similar to Ti-Por®.

Stainless Steel

Adler Ortho® employs Powder Manufacturing Technology to produce some surgical instruments, for instance knee cutting blocks.

Clinical Results

The Fixa Ti-Por® acetabular cup had been succesfully launched in 2007, while the Parva stem, the 1st hip stem ever produced directly out of metal powders, had been in clinical use since 2009.
Available clinical data look very encouraging:

The Fixa Ti-Por® cup showed an overall survival rate of 98.7% at 8.5 years (Data collected on a cohort of 9,684 patients)*. The cup showed a higher overall survival rate when compared with all the other press-fit cementless cups included in the RIPO registry - (*) RIPO Joint Registry Registro Regionale Implantologia Protesica Ortopedica dell’Emilia-Romagna

The Fixa Ti-Por® cup received a 7A* rating from the British Orthopaedic Devices Evaluation Panel (ODEP www.odep.org.uk). It’s a rating certifying implants reliability according to available and verifiable clinical data with very strict specifications. The 7A* rating is the highest one achievable for implants that reached 7 years follow-up.

100 Parva stems implants with a minimum 42 months follow-up: 100% survival rate.
