NMPA Updates: Four Orthopedic Guidelines Published in One Day


NMPA issued four orthopedic guidelines on June 9, 2020 to guide manufacturers for local type testing and regulatory approval.

  • Registration Guideline on 3D printed acetabular cup products
  • Registration Guideline on 3D printed artificial vertebral body
  • Registration Guideline on Total knee prosthesis system products
  • Registration Guideline on Heat and moisture exchanger

China has surpassed Japan as the second largest market for orthopedic medical devices in the world. With an aging population and improvement in health insurance policies, the demand for orthopedic surgeries in China, such as total knee replacement, ankle fracture and spinal fusion, have been increasing rapidly.

In terms of 3D printing for orthopedic applications, the “Customize-Designed Additive Manufactured (3D Printed) Medical Device Technical Review Draft Guideline” was issued on February 26, 2018. It specifies that, when there is no predicate device to compare to (innovative products) with limited patient volume and no readily available referenced devices, NMPA is only asking for 10 to 20 pairs of an observatory study. It can be used in conjunction with historical data to do the general analysis. A 3-month follow up period is the minimum requirement to determine the observatory clinical benefits. It is relying on post market follow up evidence with such a short endpoint and small sample size.
