[Percutaneous reduction and stabilization of a dislocated acetabular fracture. Case report].

In the treatment of acetabular fractures, anatomic reconstruction of the joint is the primary aim. To achieve this, rather large approaches with approach-related morbidity are needed. Percutaneous stabilizations are still limited to nondisplaced or minimally displaced fractures. For displaced acetabular fractures there are percutaneous procedures described with intraoperative CT control, requiring that CT be available in the OR and posing a logistic challenge. The fluoroscope Siremobil Iso-C3D offers the possibility of displaying osseous structures with CT-like quality using a fluoroscopy technique. The case of a minimally displaced acetabular T-type fracture with a clear articular step in the weight-bearing area is presented. The percutaneous reduction and stabilization after intraoperative control of the reduction quality with the Siremobil Iso-C3D is demonstrated. Using the enhanced fluoroscopy technology with the ability to generate axial cuts and reconstructions comparable to CT clearly improves the reduction control also in acetabular surgery. Thus even displaced acetabular fractures can be reduced and stabilized percutaneously. Anatomic reconstruction of the joint remains the primary aim.
