To evaluate the feasibility and accuracy of CT percutaneous fixation of sacroiliac fractures in trauma patients.

25 patients (11 female, 14 male, mean age 45.1 years, range 16 - 84 years) with unstable traumatic pelvis fractures has been advocated to minimize complications and avoid further injury. Patients were positioned in supine position under general anesthesia on the CT table. Treatment planning was with a MSCT scan with 4 x 2.5 mm collimation (120 KV, 80 mAs): Afterwards skin entrance points were marked. After that guide pins (diameter 2.5 mm) were placed under CT guidance. Following confirmation of depth, position, and angulation of guide pin with CT images a 7 mm cannulated screw of appropriate length was placed through a small skin incision.  

It was possible to place all planned guide pins under CT-guidance without complications. A total of 61 guide pins were inserted as follows: 27 guide pins were placed on the right side, 34 were placed on the left side. 7 patients got percutaneous fixation on both sides. All guide pins could be placed correctly in the first and second sacral segment through the sacroiliac joint. All cannulated screws could be placed via the guide pins without complications. Postoperative CT-scan verified the correct positioning of the screws without perforation in anterior or posterior direction and without affection of the foramen of the nerve roots.

CT guided fixation of unstable pelvic fractures is a safe and feasible method to minimize complications and to avoid further injury.

To present a method for minimal invasive internal fixation of unstable sacroliac fractures using CT guidance.
