Modular Revision Prosthesis Overview

This document details specifications and components of a modular revision prosthesis system primarily made from titanium alloy Ti 6AL 4V ELI, compliant with ISO 5832-3 and ASTM F136 standards.

Material Specifications

• Material: Titanium alloy Ti 6AL 4V ELI
• Standards: ISO 5832-3, ASTM F136

Modules and Dimensions

The prosthesis system includes modules with different diameters and offsets, each identified by reference codes and lengths (L3) in millimeters.

Module Ø 17

• Reference codes: 1265/01 to 1265/08
• Lengths available: 50, 60, 70, 80 mm

Module Ø 21.5

• Reference codes: 1266/01 to 1266/08
• Lengths available: 50, 60, 70, 80 mm
• Offsets: 41 mm for references 1268/01 to 1268/04 and 1268/08 to 1268/11; 46 mm for references 1268/19 to 1268/22

Handles for Modules

Handles are provided for modules with diameters 17 mm and 21.5 mm, with lengths of 130 mm, 160 mm, and 210 mm.

Fixation Screws and Plug Screws

• Screws to fix the distal rod are specified for Ø 17 and Ø 21.5 modules.
• Plug screws are referenced as 1270 and 1271.

Material for Screws

• Material: Chromium Cobalt Molybdenum (Cr Co Mo)
• Standards: ISO 5832-4, ASTM F75

Interchangeable Heads

Interchangeable heads are available with various lengths and diameters, referenced by codes 1088 and 1268 series, with lengths of 130 mm, 160 mm, and 210 mm.

Length Variants for Components

• Lengths range from short (28 mm) to extra long (22 mm and 28 mm variants), with specific reference codes for each length.

Summary of Critical Parameters

• Material compliance with international standards ensures biocompatibility and mechanical strength.
• Multiple module diameters and offsets allow customization for patient anatomy.
• Handles and screws are designed to securely fix components during surgery.
• Interchangeable heads provide modularity and adaptability in revision procedures.

This modular system supports a range of sizes and configurations to accommodate diverse surgical needs in orthopedic revision prosthesis.
