Abstract:

BACKGROUND: CT scan DICOM data from the use of Mimics software is the internationally recognized “gold standard” of computer-assisted surgery.
OBJECTIVE: To investigate a viable means of computer assisted surgery.
METHODS: CT Dicom format image of one case of pelvic tumors was imported into Mimics 10.01, three-dimensional reconstruction of the geometry model of total pelvis was performed including iliac artery. According the standard classification of Enneking and Dunhan, the case was type Ⅱ. All data from mimics three-dimensional reconstruction of the geometry model of total pelvis were used for preoperative measurements, surgical simulation in extensive resection of pelvic tumor and prostheses replacement surgery.

RESULTS AND CONCLUSION: The results showed that by using the mimics, the three dimensional geometric model of total pelvis accurately reflected the structure of pelvis and predicted the tumor size, and could be rotated to benefit observation, measured every parameter accurately needed in the operation, provide useful data for custom-made acetabular prostheses and effectively realized surgical simulation in extensive resection of pelvic tumor and prostheses replacement surgery. The 3D reconstruction of geometry model of the total pelvis including the iliac artery using mimics can clearly display the pelvis internal anatomic structure and type the tumor, therefore providing a fast, convenient, precise, repeatable application model for preoperative planning and simulation.
