✦ Synopsis

Results obtained by physical methods of examination, particularly X-ray diffraction, polarizing and electron microscopy and more recently differential thermal analysis, are reviewed. The different structures of the elastic wall of the disc (annulus fibrosus) and the gel-like centre of the disc (nucleus pulposus) are described in relation to their functions. An important component of aged nucleus pulposus is a substance giving an X-ray diffraction spacing of 4.7 A, presumably a denatured protein in the ~-form, but its origin is still obscure. The value of differential thermal analysis in the study of collagen of the disc and other connective tissues is illustrated.

Proteoglycans attract fluid, which works to reduce mechanical stresses in the solid matrix of the nucleus and provide a hydrostatic pressure to the

## Abstract There have been very few studies on the metabolism of the intervertebral disc. One possible reason is that lumbar discs suitable for in vitro synthesis studies are difficult to obtain. We have examined some properties of coccygeal discs to see if those discs are a suitable alternative.

Fifteen lumbar spines were collected postmortem. The interverte-bra1 discs were assigned morphological grades and were analyzed for water, collagen, and proteoglycan. In order of increasing degeneration, five grade 0, four grade 1,45 grade 2, 12 grade 3A, and nine grade 3B discs were identified. The
