[CT-guided pelvic osteosynthesis. Preliminary report on a new operative technic].

The authors proposed new method for surgical treatment of slightly dislocated fractures of the sacrum and acetabulum and also small traumatic dislocations in the sacroiliac joint. Cannulated screws were used for percutaneous osteosynthesis under guidance of computerised tomography. CT guided surgery enables to choose the correct direction and length of introduced screws with regard to the shape and localisation of the fracture. During the step by step procedure the reduction effect can be directly checked and the surgical strategy immediately modified. The advantages of this method are minimal invasiveness, high accuracy and possibility of rapid mobilisation of treated patient.
