[Model for the study of influences on fracture healing. Animal experiments].

Abstract

Primary and secondary bone healing were studied for 30 and 60 days, respectively, by means of X rays, scintigraphy, determination of callus thickness, scintillation counter, and determination of bone mineral content. Primary bone healing was terminated after 30 days, secondary healing after 60 days. Scintillation counting proved to be a quantitative method, the other methods serving as controls. The different influences on bone healing can be quantitatively studied by means of this model.
