Cups Shells

Product catalog summary

Overview: The document outlines the specifications and descriptions of acetabular components used in hip revision surgeries, focusing on materials like UHMWPE and TiAl6V4, compliant with DIN EN ISO standards.

Specifications:

Müler Acetabular Cups: These are available in sizes with outer diameters from 38 mm to 70 mm and inner diameters of 22.2 mm, 26 mm, 28 mm, and 32 mm. They are made from UHMWPE and are suitable for revision and dysplastic cases.
Modular Acetabular Inserts: High Wal inserts range from 20 mm to 32 mm, designed to enhance joint stability.
CIF BIOTANTM Modular Acetabular Shells: Offered in 5-holed and solid versions, with sizes from 38 mm to 76 mm, featuring a Biotan plasma-sprayed porous titanium coating for enhanced stability.
Acetabular Fixation Screws: Made from TiAl6V4, available in lengths from 15 mm to 45 mm.

Procedures and Recommendations:

Gamma Irradiation: UHMWPE components are gamma irradiated in an oxygen-free environment to improve wear resistance.
Design Considerations: Focus on initial stability, ingrowth surface, and insert/shell congruency for long-term component survival.
Coating Specifications: Plasma-sprayed porous titanium coating with about 30% porosity and pore sizes from 75 to 350 microns.

Norms and Standards:

Components comply with DIN EN ISO 5834-2 and 5832-3 standards.

Key Features:

Enhanced Fixation: Features like circumferential grooves and rim tabs improve cement/cup fixation and rotational stability.
Range of Motion: A 30º chamfer design maximizes range of motion and reduces impingement risks.
Modular Options: Allows intraoperative combination of inserts (ceramic, metal, polyethylene) for customized solutions.

CIF Uncemented Acetabular System Long term survival of acetabular components is depending on established design considerations such as: inital stability, ingrowth surface, insert fixation and insert/shell congruency. The CIF acetabular components meet those criteria, thereby offering a solution to stable acetabular component fixation. The titanium hemispherical shell is available in 5-holed and solid (1 hole) version. Both are provided with a 15° rim flare, oblique peripheral fins and tabs on the rim for rotational stability and additional fixation, and coated in Biotan plasma-sprayed porous...
