[Collection of autologous bone transplants].

For the collection of autologous cancellous bone transplants normally the anterior and posterior parts of the Os ilium are used. With proper techniques the conture of the pelvis and the muscle insertions can be conserved. All other collection places should only be used in unexpected situations and need of only small amounts of transplant. Serious complications are fractures and nervous lesions, which can be avoided by a careful procedure.
