[Precise sacroiliac joint screw insertion without computed tomography, digital volume tomography or navigation systems]. Oper Orthop Traumatol. 2019 Jun 03;: Authors: Roetman B, Ilchuk I, Khatib B, Goerigk U, Gothner M Abstract OBJECTIVE: Improvement of sacroiliac positioning of screws by detailed preoperative planning with a DICOM (Digital Imaging and Communications in Medicine-the international standard to store and process medical imaging information) workstation in the absence of advanced technical facilities like intraoperative computer tomography (CT), digital volume tomography (DVT) or a navigation system. INDICATIONS: Mono- or bilateral non- or minor displaced, longitudinal sacral fractures type Denis I and II and pelvic ring fractures (Orthopedic Trauma Association) OTA type B possibly in combination with a ventral procedure. CONTRAINDICATIONS: Displaced sacral fractures type Denis II and III, fractures with central comminution and circulatory unstable patients to be stabilized in the context of emergency care. SURGICAL TECHNIQUE: Preoperative calculation of virtual conventional standard view X‑rays with the CT dataset using common DICOM software (e.g., Siemens via® or Sectra®). Typical landmarks such as screw entry point and end point are projected into the virtual X‑rays. Intraoperative navigation is performed by comparing the virtual standard views with fluoroscopic images of the C‑ar...
