Computer-Assisted Resection and Reconstruction of Pelvic Tumor Sarcoma
Figure 2
(a) A model of the patient’s iliac bone with the tumor was created by rapid prototyping. A preoperative rehearsal of the tumorous resection was realized with the computer-assisted navigation system. (b) Prototype of the patient with the tumor. The osteotomy line was first traced with the navigation pointer to mark up the entry point of the saw. (c) Computer-assisted system allowed us to cut the 2 iliac bone prototypes: the patient (on the right) and the allograft (on the left). The cutting planes are identical for the two procedures. (d) The fitting of the graft model into the patient’s iliac bone model is checked.
