Subjects receive receive computer assisted placement of the sacroiliac screws. The computer assisted placement will be performed by using the BrainLab Vector Vision®Trauma Navigation Software. Two approaches will be used, the 2D navigation and 3D navigation.

Subjects receive standard fluoroscopic placement of the sacroiliac screw.
Standard treatment for sacroiliac dislocations and sacroiliac fractures is placement of two screws through the iliosacral joint into the sacral ala or the body of the S1 vertebra. Correct positioning is technically demanding. Screw displacement may reduce the strength of fixation and lead to neurological complications.
Secondary objectives of the study are to compare the fluoroscopy time, complications and surgery duration between the treatments.
