[The influence of medication with calcium and vitamin D2 on incorporation and micro-hardness of cancellous bone grafts and cortical grafts (author's transl)].

An investigation on the superiority of autogenous cancellous bone grafts compared to cortical grafts in guinea pigs by means of the micro-hardness test of Vickers revealed an improvement of hardness of the transplants as well as of the frame structure, i.e. an amelioration of physical bone properties due to medication with a calcium-vitamin D2 combination (Frubiase Calcium forte).
