Correlation Between Conditional Approval and Customized Bone Implant Devices.

Area of Science:

• Biomaterials and Medical Devices
• Regulatory Science
• Orthopedic Surgery

Background:

• Premarket evaluation of bone implants involves customized devices and conditional approval.
• China's regulatory landscape for custom devices is nascent compared to international standards.

Purpose of the Study:

• To summarize concerns regarding customized devices and conditional approval for bone implants.
• To explore the correlation between these two aspects in premarket evaluation.
• To provide insights for China's regulatory development.

Main Methods:

• Analysis of the approval process for the first domestic custom-designed bone implant.
• Review of conditional approval pathways for urgent and rare disease medical devices.
• Examination of clinical investigation guidance and post-market surveillance.

Main Results:

• Customized devices and conditional approval show certain connections, but are not directly correlated.
• China's regulations for custom devices lag behind the USA, Canada, Australia, and the EU.
• Significant potential exists for China to refine policies for custom devices and conditional approval.

Conclusions:

• Conditional approval can aid China in developing effective policies for custom bone implants.
• Individualized, anatomy-matching bone implants with scientific conditional approval can advance precision medicine.
• Developing robust regulatory strategies is crucial for ensuring the efficacy of custom medical devices.
