The use of CT derived solid modelling of the pelvis in planning cancer resections.

CLINICAL PROBLEM: Resection of malignant tumors of the pelvis is demanding.

To achieve adequate reconstructions custom-made replacements were recommended. In early stages of the surgical procedure using megaprostheses, individual pelvic models were manufactured.
