Abstract

The effects of chondrodiatasis on chondrocyte division, matrix synthesis, and microcirculation in rabbit growth plate were studied. The procedure did not produce any significant change in the percentage of cells labeled with tritiated thymidine, the intensity of radioactive sulfate labeling of the matrix, or the blood supply of the physis. These findings suggest that the procedure does not work by stimulating cell division, synthetic function, or vascularity of the plate, but rather by stretching the matrix passively.
