YY/T 0809.2-2020 Implants for surgery—Partial and total hip joint prostheses—Part 2:Articulating surfaces made of metallic,ceramic and plastics materials
Basic Information
Scope
This part of YY/T 0809 specifies the requirements for the joint surfaces of various total and partial hip joint prostheses with a socket structure, including:
a) The roundness and surface roughness requirements for metal and ceramic femoral prosthesis components used in partial hip replacement surgery as classified in YY/T 0809.1-2010;
b) The roundness and surface roughness requirements for the plastic inner surface connected to the femoral component and the metal or ceramic outer surface connected to the physiological acetabulum in the double-pole femoral head as classified in YY/T 0809.1-2010;
c) The roundness and surface roughness requirements and dimensional tolerances for the plastic acetabulum components as classified in YY/T 0809.1-2010;
d) The roundness and surface roughness requirements and dimensional tolerances for the metal or ceramic femoral components of total hip joint prostheses as classified in YY/T 0809.1-2010.
This part applies to the joint surfaces of various total and partial hip joint prostheses with a socket structure.
