Plasmafit® Revision

Your solution within the Plasmafit® Family

Cementless acetabular revision

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.

Plasmafit® Revision – Characteristics

Plasmafit® Revision – Highlight Topics

Laser-Sintering Technology

The profile structure of the Plasmafit® Revision cup surface is characterized by a special, very rough Structan® titanium structure. The structure is produced by an additive 3D printing process. This laser-sintering process permits precise and continuous shaping of the porous and dense implant design structures.

Intraoperative Flexibility

Plasmafit® Revision permits an intraoperative selection of modular liners made of Vitelene® as well as Dual Mobility liners.
Plasmafit® Revision has three single-hole screw holes and two oblong holes. To bridge larger defects, an acetabular Structan® Augment can be additionally implanted.

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.

Plasmafit® Revision with Plasmafit® Dual Mobility

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 combination is possible starting with cup size ø 46 mm.

Plasmafit® Revision Liner Anchoring

The design of the Plasmafit® Revision inner geometry permits an intraoperative selection of modular liners made of Vitelene® as well as Dual Mobility liners.

Large-area conical fixation in the cone area of the cup is used to anchor the Plasmafit® Revision liners. The rough titanium inner surface reduces relative movements of the liner to a few micrometers. The conical fixation surface area of the Plasmafit® Revision polyethylene liners also forms a seal against the migration of polyethylene particles from the articulating joint, thus reducing the risk of an osteolysis adjacent to the screw holes.

The Vitelene® Revision liners have a special geometrical shape with a snap connection. This enables mechanical fixation in the Plasmafit® Revision cup. The snap mechanism consists of the protruding snap lip at the upper end of the conical area of the liner and a small gap. The geometry of the inner cup reflects this protruding rim. This snap connection provides the revision liner with an additional anchoring option. The small gap / recess at the cup entrance plane is used to remove the liner in case of a revision.

Plasmafit® Revision with Structan® Augments

Bone defects can exceed the shape and size of the dimension of the revision cup. For stable anchoring and to bridge larger defects, an acetabular Structan® Augment can be additionally implanted.

Structan® Augments consist of a titanium alloy and permit the filling of defects, providing a stable grid structure and high surface roughness. The augments are adapted to the diameter of the Plasmafit® Revision cup. The diameter of the revision cup should be within a range of ±4 mm of the size of the selected Structan® Augments.
