Abstract

The initial contamination of femoral head, femoral stem and femoral component producted by seven factories in Beijing is tested, all of the initial contamination values are 580 in total. Then these data is analyzed on statistics. The result indicates that the initial contamination values of three kinds of products according with normal distribution; The initial contamination values have not significant difference between femoral head and femoral component of the same factory; and the season has not significant effect on initial contamination in Beijing. According to the experimental data, the level of initial contamination is undulatory, so the factories should control the initial contamination and maintain the stability of initial contamination.
