H. Yano et al., QUANTITATIVE-ANALYSIS OF REVASCULARIZATION AND NEW BONE-FORMATION IN EXPERIMENTAL BONE-GRAFTS - THE USE OF AN IMAGE INPUT AND PROCESSING SYSTEM, International orthopaedics, 17(2), 1993, pp. 109-112
Revascularisation and new bone formation in bone grafts has been exten
sively studied by histological techniques, but the images obtained are
very complex and consequently difficult to evaluate quantitatively. W
e report similar analyses in experimental bone grafts using newer comp
uterised digital techniques. Fresh autografts and fresh and frozen all
ografts were used. The histological analogue images from them were inp
ut digitally into an image processor. The amount of revascularisation
and new bone formation could then be quantified in the different graft
s. This system has proved to be a useful method of evaluation which co
uld be applied to the quantitative analysis of other histological imag
es.
