The Plasmafit® acetabular system features and combines several important elements for cementless orthopaedic implants: High primary stability even in difficult conditions, low-abrasion articulation and ideal implant position. The Plasmapore® surface provides through its roughness a strong connection to the bone. The possibility of a bioceramic Biolox® ceramic insert provides highest lubricity and minimum wear. With Vitelene® (highly-crosslinked polyethylene with vitamin E)there is a new material available, which is characterized by high wear and oxidation resistance throughout the life of the hip arthroplasty. This plays an important pioneering role in the field of highly-crosslinked articulation. The OrthoPilot® Navigation technology combines these features with the possibility of an exact implant positioning.
The cementless Plasmafit® acetabular cup system is particularly distinguished by the composition of the implant surface. The precise and fine tooth geometry in combination with the microporous pure titanium coating Plasmapore® ensuresvery high primary implant stability. This thin layer has an osteoconductive effect and accelerates contact between the bone and the prosthesis stem.
Vitelene® highly-crosslinked Polyethylene with Vitamin E
Apart from the cup design the new polyethylene insert articulation material Vitelene® plays a crucial role in the success of the Plasmafit® cup system. Vitelene® is a highly-crosslinked polyethylene mixed with 0.1% of antioxidant vitamin E (α-tocopherol) and electron beam radiated. By adding vitamin E, a thermal treatment is not necessary. Vitelene® is therefore protected and the mechanical properties are preserved.The long-term stability of Vitelene® against oxidation is of particular clinical importance, as it directly correlates with wear.
Plasmafit® can be implanted with Biolox® delta ceramics, the latest generation of bioceramics for hip arthroplasty. The ceramic on ceramic bearing surfaces guarantee minimal wear. The favorable wettability of the surfaces allows good joint lubrication. The ceramic material is extremely scratch resistant and at the same timefully biocompatible.
The self-locking conical anchoring stabilizes the modular Plasmafit® inserts, preventing any micromovements. The area in which the resultant forces are concentrated is provided with the maximum material thickness. Optional anchoring screws for Plasmafit® Plus can be orientated freely during insertion. The modular range of implants with different fixation options offers the surgeon a choice: ceramic or highly-crosslinked polyethylene inserts with Vitamin E. Implant components can therefore be chosen to suit the individual requirements of the patient.
Plasmafit® can be implanted with the OrthoPilot® navigation technology. In navigated Plasmafit® surgeries the system measures the inclination and anteversion angles relative to the anterior pelvic plane. During acetabular reaming, the joint center, the reaming depth and the orientation of the reamer are measured and displayed. Plasmafit® navigation with OrthoPilot® is suitable for different patient positions and surgical approaches.
