Vitamin E stabilized highly crosslinked polyethylene - Applied technology. In vivo performance.

Vitelene® is a highly crosslinked polyethylene blended with vitamin E. Vitamin E provides long-term oxidation protection by binding free radicals through the release of H atoms. Polyethylene powder GUR 1020 is mixed with vitamin E (0.1 % - α-tocopherol) and pressed into sheets. Afterwards a total dose of 80 kGy electron beam radiation is applied to crosslink the blank product. Vitelene® inserts are manufactured using CNC technology and sterilized with ethylene oxide. Vitelene® needs no thermal treatment and has, therefore, balanced mechanical properties. It is characterized by wear and oxidation resistance. The articulation material Vitelene® is offered with the AESCULAP® acetabular cup systems Plasmafit®, Plasmafit® Dual Mobility as well as Plasmafit® Revision.

Highly crosslinked polyethylene with vitamin E In contrast to polyethylene implants which are doped with vitamin E by diffusion as finished parts, blending of polyethylene by mixing vitamin E already into the raw powder guarantees a vitamin E concentration also in the deep areas of the material. Thanks to its excellent wear and oxidation resistance and balanced mechanical properties, Vitelene® represents the latest generation of highly crosslinked polyethylene for total hip arthroplasty.

Good longterm results The wear rate of Vitelene® is very low even after extreme artificial aging. The vitamin E concentration is still sufficient to eliminate oxidative reactions and therefore reduces wear throughout the whole lifespan of the total hip arthroplasty. Oxidation leads to degradation of polyethylene. Vitamin E increases the resistance of polyethylene against oxidative processes and strengthens the bearing material. The mechanical properties impact strength, tensile strength and elongation of Vitelene® are unchanged even after 42 days of artificial aging. Thus the laboratory tests show an excellent longterm stability of Vitelene® against mechanical stress.

Plasmafit® Family

One Acetabular Cup System

The AESCULAP® Plasmafit® Family provides an acetabular solution for total hip joint replacements. It covers indications from primary up to revision treatments. Patient-specific requirements are addressed in one system and complement each other using the same instruments, inlays, design parameters and surgical procedure.

Vitelene® for

The Plasmafit® cup system stands for an acetabular treatment option within the cup family of AESCULAP®. Different requirements for patient specific solutions are combined in one system and complement each other by the use of the same instruments, design
parameters and surgical procedure.

Plasmafit® Poly is a dedicated cup implant line exclusively for the use with polyethylene liners. The profile of the wall thickness enlarges the material thickness of polyethylene liners and allows the optional use of correction liners.

Plasmafit® Plus designed for combined treatments with ceramic or polyethylene articulation materials. The increased wall thickness compared to Plasmafit® Poly allows additional screw holes for an optional use of cancellous fixation screws. All Plasmafit® Plus cup implants can be combined with modular Vitelene® polyethylene liners made of vitamin E stabilized highly crosslinked polyethylene.

The Plasmafit® Dual Mobility concept addresses a high stability preventing hip joint dislocations. Plasmafit® Dual Mobility liners can be combined with all cup options
of the Plasmafit® Plus and Plasmafit® Revision cup implants.

Dual Mobility head is made of Vitelene® highly cross linked polyethylene with vitamin E and offers good gliding properties as well as abrasion reduction.

The AESCULAP® Plasmafit® Family reflects a comprehensive solution for primary hip joint replacement.
Based on the properties of the materials and instruments, Plasmafit® Revision has joined the family and continues the system concept. Various polyethylene bearing options are available based on the proven Vitelene®, a highly crosslinked polyethylene with vitamin E, including special revision liners.

Vitelene® Standard Liners:

  • Symmetrical
  • Asymmetrical 10°
  • Posterior Wall

Vitelene® Revision Liners:

  • Symmetrical + 4 mm
  • Asymmetrical 20°

The Vitelene® Revision liners have a special geometrical shape with a snap connection. This enables mechanical fixation in the Plasmafit® Revision cup.
