The influence of growth hormone upon trabecular bone remodelation is not definitely clear. The authors of this study compared static and dynamic histomorphometric data of bone patterns of 28 numbered group of acromegalics and 35 numbered group of healthy individuals. They correlated also levels of growth hormone, thyroxine, prolactin and testosterone in men with histomorphometric parameters in acromegalic patients. The results showed statistically significant differences between normal and acromegalic trabecular bone, which has comparable trabecular volume, but significantly wider bone trabeculae and lower mean trabecular density. There were no correlations found between growth hormone levels and levels of thyroxine, prolactin, measured testosterone and histomorphometric parameters.
