Unstable pelvic fractures are usually associated with high energy injuries and influence negatively the post-injury reaction. As to surgical procedures most frequently methods of inner osteosynthesis are used which however cannot be applied in the acute stage of treatment, particular in multiple injuries. Percutaneous fixation under skiascopic control lacks precision of fracture stabilization in deeper layers. The mentioned shortcomings are overcome by percutaneous fixation under CT control. It is minimally invasive and markedly reduces the risk of infectious complications. CT control provides direct visualization of fragments of the fracture and foramina of the sacral bone and makes it possible to place quite reliably the screw to rule out or minimalize damage of nerve fibres. It also reduces the chance of damage of pelvic vessels. The disadvantage is a greater radiation load as compared with procedures made under skiascopic control. By optimalization of image-taking parameters it can be however markedly reduced. In the presented paper the authors submit their own initial experience with percutaneous operati- ons under CT control in two patients and they review briefly experience from the literature concerned with this problem.
