Prevision® Modular Hip Revision Stem

Bridging bone defects for secure implant fixation

The Prevision® Concept can be realized with straight or curved stems. Following the reverse principle, it aims to revert from temporary stable distal fixation to proximal force transfer.

Previson® at one glance

  • Modular revision endoprosthesis with straight and curved stems.
  • 500 total possible combinations of proximal and distal components.
  • Proximal component is coated with Plasmapore® µ-CaP surface.
  • Rotational stability through star shape and distal interlocking option.
  • Catch-free stability by applied frictional connection.
  • Multiple opportunities for trial reduction.
  • Intra- and extraosseous assembly of the implant component.

The modular Prevision® revision endoprosthesis is available with distal diameters from 12 mm to 24 mm. The straight stem comprises im plant lengths from 200 mm to 320 mm. The anatomic curved stems are from 240 mm to 400 mm long. The 40 mm length increments of the stem are combined for finer adjustment with proximal Prevision® components which are available in length increments of 0 mm, +10 mm and +20 mm.

Because the implant components can be assembled intraosseous, the leg length can be adjusted at the last possible stage of the implantation procedure.

Prevision® Straight

The Prevision® Instruments offer multiple opportunities for trial reduction and the stable connection of the implant components.

A counterholder applied to the distal component minimizes the transfer of torque onto the distal implant site during the intraosseous assembling.

Prevision® Curved

Using Prevision® Curved the femoral implant bed is prepared with flexible reamers and modular distal and proximal trial rasps.

The stability of the fixation is achieved by the stem length, the sub-proximal cone and the optional distal interlocking of the anatomical curved modular stem.

The semicrystalline calcium phosphate (CaP) of high purity is combined in an electrochemical process with the Plasmapore® titanium surface at a layer depth of 20 µm.

Thanks to the osteoconductive properties of the dicalcium phosphate µ-CaP, the bone forms more rapid direct contact with the implant surface.

Plasmafit® Revision is an acetabular cup system for both primary treatment and revisions of differently located acetabular defect situations.

The hemispherical shape and the laser-sintered titanium structure of the acetabular cup provide high primary stability. To achieve good stability for larger acetabular defects, the design has a total of five options for anchoring screws.

In addition, Structan® Augments can be combined with the Plasmafit® Revision cup for treating larger defects.
