Scanning electron microscope (SEM) was used to observe the articular cartilage surface of rabbit’s ulnar ulnar articular cartilage. The results showed that the articular surface of the trochlear and trochlear notch had complicated mesh structure. The helical track of the lip of the trochlear articular surface was tightly fitted by the flake Secondary spiral structure; small head - slippery valley at the end of the gutter, formed by the irregular shape of the sheet-like structure; notch notch Nudata nest, there are more coarse fibrous web and adipose tissue exist.
