[Refilling of bone defects after taking out of bone transplants (author's transl)].

The author recommends to refill the donor defect by preserved allogeneic cancellous bone chips. In this way much more autogenous material for grafting can be gained. At the site of the taking out a restitutio ad integrum will take place. This procedure has been practised in 387 donor bone defects. Technical details and results are dealt with.
