3D reconstruction of the pelvis using the NSCP technique

Many authors have already pointed out the importance of the three dimensional aspect when dealing with pelvic and spinal pathologies. The purpose of the present study is to verify the feasibility on the pelvis and the accuracy of a recent 3D reconstruction technique based on biplanar X Rays with regard to direct measurements. The results on 8 dry non-pathologic pelvises show a mean error of 3.9 mm for the global geometry of the pelvis, with local maxima of 26 mm and 95% of errors inferior to 14.5 mm.
