Abstract
We made the preoperative planning for pelvic osteotomy using stereolithography besides the 3-DCT. The subject cases were five, all women, of which one case has undergone Pemberton's operation, three rotational acetabular osteotomy, and one rotational acetabular osteotomy combined with advancement of greater trochanter.
The advantage of the simulation with 3-DCT was the possibility of processing the images in various ways and times. On the other hand, the stereolithography was incomparably good in its solid sense. The easiness to understand the anatomy and the sense of security during the operation were exceptional. The preoperative planning to combine 3-DCT with stereolithography has many cumbersome procedures, but we would like to emphasize that if it is used for a complementary, purpose, its merits can further be amplified and that though not a surgical simulation in the strict sense of the words, this method has reached a fully practical stage as a surgical navigation.
