## Introduction
Before an orthopedic implant can be inserted into a human body, it must be proven safe at a cellular level. This process is known as **Biocompatibility Testing**. Following the **ISO 10993** framework, manufacturers must ensure their products do not cause harmful biological reactions.
## The Core Biocompatibility Tests
For permanent orthopedic implants (Ti6Al4V or SS316L), the following tests are non-negotiable:
1. **Cytotoxicity:** Testing the material against living cells to ensure it doesn’t kill or inhibit cell growth.
2. **Sensitization:** Ensuring the metal or its coatings do not trigger an allergic or immune response over time.
3. **Irritation:** Checking if the implant causes inflammation in the surrounding tissues.
4. **Systemic Toxicity:** Evaluating if tiny particles or ions from the implant could travel through the bloodstream and harm organs like the liver or kidneys.
## The Role of Material Purity
Biocompatibility is directly linked to the purity of the raw materials. Even a trace amount of a non-medical element (like nickel in a titanium alloy) can trigger a reaction. This is why Ortholyx utilizes **Vacuum Induction Melting** to ensure absolute material purity.
## Ortholyx Compliance
All Ortholyx implants have undergone exhaustive biocompatibility validation in GLP-certified laboratories. We provide full biological evaluation reports to our B2B partners to support their local regulatory registrations.
## Conclusion
Biocompatibility is the bridge between medtech and biology. By strictly adhering to ISO 10993 standards, Ortholyx ensures that our implants integration seamlessly with the human body, providing a lifetime of safety for the patient.
