โœฆ Synopsis


Revascularisation and new bone formation in bone grafts has been extensively studied by histological techniques, but the images obtained are very complex and consequently difficult to evaluate quantitatively. We report similar analyses in experimental bone grafts using newer computerised digital techniques. Fresh autografts and fresh and frozen allografls were used. The histological analogue images from them were input digitally into an image processor. The amount of revascularisation and new bone formation could then be quantified in the different grafts. This system has proved to be a useful method of evaluation which could be applied to the quantitative analysis of other histological images.

R6sum6. La revascularisation et la formation d'os nouveau dans les greffes osseuses ont dtd 6tudi6es en d6tail par les techniques histologiques. L'information analogique fournie par les images histologiques est cependant difficile gt dvaluer quantitativement, car ces images sont trks complexes. Darts cette 6tude nous avons analys6 quantativement la revascularisation et la formation d'os nouveau, au cours de greffes exp~rimentales, en utilisant les techniques les plus

r~centes d'ordinateurs num6riques. Trois sortes de greffes ont 6td utilisdes: l' autogreffe fra?che, l'allogreffe frafche et l'allogreffe congelde. Les images histologiques analogiques de ces greffes ont 6td introduites numdriquement dans un processeur d'images puis analys~es. Ainsi nous avons pu quantifier la revascularisation et la formation d'os nouveau dans ces diffdrents types de greffes. Cette ~tude montre que cette mdthode est trks utile pour ~valuer
