Verletzungen des Azetabulums

Anatomic reduction of the articular surface is essential in the definitive therapy of acetabular injuries. The required surgical approaches with extensive and deep exposure of the adjacent soft tissue may cause additional iatrogenic trauma. Computer-aided navigation based on 2D and 3D fluoroscopy is increasingly being applied for successful percutaneous screw fixation. Non-dislocated or minimally dislocated but unstable fractures are particularly suitable for navigation. The advantages of computer-assisted navigation are the improved accuracy of screw placement and reduced radiation exposure as well as protection of the soft tissue. Therefore, percutaneous navigated screw fixation is a promising alternative to conventional operative procedures in selected acetabular fractures considering the primary goals of anatomic reduction and rigid fixation allowing early exercises.
