He believes that an understanding of the blood supply and its fate is of special importance for the understanding of the later development of the intervertebral disk and states:

The explanation of some of the nucleus pulposes into the spongiosa of the vertebral bodies occurring at an age when the senescent degenerative changes of the cartilaginous plates are only minimal can be based on it. The intervertebral disc is constantly exposed to more or less severe trauma and it is one of the earliest structures to show definite senescent changes. This is partly explainable on the development and the early regression of the vascular supply.
