Abstract: The surgical reconstructive treatment in the pelvis area is induced mostly by the bone tumour resection. This paper presents a new method for computer-assisted reconstructive surgery-planning based on the pelvis statistical shape model. A clinical pelvis reconstruction case will demonstrate the usefulness and robustness of the statistical shape models in the oncologic surgery planning. In addition, a quantitative evaluation of the matching quality will be given. By creating the statistical shape model, we get a mathematically defined mean pelvic geometry. Knowledge about the statistical pelvic shape can have wide application in pelvimetry.

Keywords: statistical shape modelling; pelvic osteotomy; pelvic reconstruction; segmentation; computer-assisted surgery planning; pelvic tumours; bone tumour resection; oncology; pelvic geometry; statistical pelvic shape; pelvimetry.
