Perkutane navigierte Ballonreposition einer dislozierten Acetabulumfraktur

Kyphoplasty is a well proven surgical procedure for osteoporotic fractures in spine surgery. Anatomic reconstruction of the joint is the primary aim in the treatment of acetabular fractures. To achieve this, extensive approaches with entry related morbidity are usually needed. Percutaneous stabilisations are still limited for non- or minimally displaced fractures.For displaced acetabular fractures, there are percutaneous procedures described with intraoperative CT control or by the use of a 3D C-arm. The case of an anterior column posterior hemitranverse fracture with an articular step in the weight bearing area is presented. In this case, a kyphoplasty balloon was placed by use of 3D C-arm navigation. After 2D C-arm controlled fracture reduction, the supra-acetabular screw was inserted percutaneously using the previous 3D navigation data set.With the combination of kyphoplasty technique, intraoperative 3D C-arm control and 3D C-arm based navigation, this displaced acetabular fracture could be reduced and fixed percutaneously. Anatomic reconstruction of the joint remains the primary aim.
