title: The arch structure of trabeculae in normal femoral head and its biomechanical significance.
abstract: The microstructure of the normal human femoral head was observed under light and electron microscope. Most of the trabeculae were seen in the form of arch structure, and the collagen fibers and mineral columns among the trabeculae were arranged in different directions. These findings provide a new explanation of the mechanism by which the femoral head can bear high stress without collapse.
