  4. Computed tomography-osteoaboorptiometry
A method of making a visual display of subchondral mineralization
in the major synovial joints is described. Unlike existing
procedures, it can be used on the living subject. A modified
application of computed tomography-densitometry, computed
tomography-osteoabsorptiometry makes it possible to explore the
mechanical adaptability to the prevailing mechanical force. This
claim is based upon the comparison of information obtained from 20
anatomical specimens with CT-osteoabsorptiometry and x-ray
densitometry of sections; both methods yielding virtually identical
results. The distribution of the subchondral density was then
expressed as a map of the articular surface with the aid of an
image analyser. This method can make a useful contribution to basic
clinical research, as well as providing a diagnostic technique
which can also be used for observing progress after a corrective
osteotomy or any other procedure causing a change in mechanical
function. Examples of its use on living patients are given.
