Nine Orthopedic Standards Issued in One Day

NMPA issued nine orthopedic standards on July 9, 2020 to guide manufacturers for local type testing and regulatory approval. Their implementation date is June 1, 2021.

  • YY/T 1701-2020 Medical Ti-6Al-4V/Ti-6Al-4V ELI powder for additive manufacturing
  • YY/T 0345.1-2020 Surgical implants Metal bone needles Part 1: General requirements
  • YY/T 0513.2-2020 Allogeneic repair materials Part 2: Deep low temperature frozen bone and frozen dry bone
  • YY/T 0651.3-2020 Surgical implants Wear of total hip joint prosthesis Part 3: Load and displacement parameters of rail bearing type wear testing machine and related test environmental conditions
  • YY/T 0726-2020 Passive Surgical Implant Devices General Requirements
  • YY/T 0809.12-2020 Surgical implants Part and total hip prosthesis Part 12: Test method for acetabular cup deformation
  • YY/T 1133-2020 Passive surgical implant combined instrument metal bone drill
  • YY/T 1714-2020 Standard method for finite element analysis of non-assembled metal hip joint femoral stem
  • YY/T 1736-2020 Test method for evaluating the durability and deformation of knee joint tibial pads under high flexion conditions

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.

Among the nine standards is one for additive manufacturing. 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.
