SELF-LOCKING FEMORAL STEMS

Product catalog summary

Overview
This document provides comprehensive information on Surgival's self-locking femoral stems, available in both cemented and cementless versions. It emphasizes the advanced European technology used in their design and manufacturing.

Specifications
The femoral stems are made from Ti6-Al4-V alloy and high nitrogen stainless steel. Cemented stems have a smooth finish, while cementless stems are coated with hydroxyapatite or titanium plasma spray on the proximal third for enhanced bone integration, with the distal two-thirds remaining smooth.

Design Features
The stems feature a flat, wedge-shaped geometry for anti-rotational stability and elasticity. A longitudinal groove allows for bone cement or trabecular bone occupation, depending on the stem type. The neck shaft angle is 135º, designed to prevent prosthetic sinking.

Instrument Sets
Complete instrument sets are available for both stem types, including trial heads, rasps, impactors, and other necessary tools for surgery.

Surgical Technique
The document outlines the surgical procedure for implanting femoral stems, detailing steps such as femoral neck osteotomy, femoral preparation, trial reduction, and component insertion. The technique varies slightly between cemented and non-cemented stems.

Key Considerations
For cemented stems, additional steps like cavity cleaning and cement preparation are necessary. The document stresses the importance of selecting the correct neck length and ensuring stability during the trial reduction phase.

Conclusion
Surgival's self-locking femoral stems offer enhanced stability and performance due to their unique design and high-quality materials. The document provides detailed guidance on surgical techniques and instrument usage for successful implantation.

Surgical Technique Overview
The procedure involves femoral neck osteotomy at a 45-degree angle, femoral canal preparation using a hollow box chisel and manual conical reamer, and progressive rasping to establish anteversion for final stem insertion.

Femoral Stem Specifications
The stems are available in both cemented and cementless versions, featuring a hydroxyapatite or titanium plasma spray coating on the proximal third for enhanced bone integration.

Implant and Instrumentation Details
The document provides specifications for various femoral stem sizes and lists the complete instrument sets required for both procedures, designed to facilitate precise implantation.

Technical Features and Benefits
The self-locking stem offers a 135-degree neck shaft angle to prevent prosthetic sinking and a longitudinal groove for enhanced stability, aiming for stable biological fixation through metaphyseal primary stability and distal mechanical support.
