title: [Semiquantitative determination of destruction dynamics at the joints of hands and feet in rheumatoid arthritis-two roentgenological methods controlling the course of the disease as part of treatment studies (author's transl)].
abstract: The article discusses briefly the problem of classifying the degree of severity in rheumatoid arthritis. The selection of the X-ray film criteria which are best representative of the destruction dynamics, is explained. Two measurement methods are described which can be used to visualise and to measure the dynamics of the destructive processes. The destruction dynamics can be visualised graphically in a co-ordinate system or as a quotient series via calculatory or planimetric evaluation - at a later stage, this can be done photometrically. It is stated that both methods, namely, the one using the standardised evaluation foil and the one utilising the special transparent foil, can yield information on the extent and progress of joint destructions.
