Surgical treatment of intraarticular calcaneus fractures. The significance of intraoperative 3D imaging

Correct reconstruction of the outer shape of the calcaneus, as well as anatomically true reconstruction of the articular surfaces are the main objectives of osteosynthesis and also a prerequisite for avoiding complications. Successful reconstruction of the articular surfaces was hitherto hindered by gaps in conventional intraoperative imaging as a result of the inability to directly visualize portions of the affected joint due to the anatomic layout. Image transformation systems are now available, which make intraoperative 3D imaging possible. In this way, axial reconstruction, implant position and the results of repositioning can be assessed during surgery for calcaneus fractures. In addition to the appropri-ate equipment, this method requires intensive training and a standardized procedure. 3D fluoroscopy is suited to improving process quality in the treatment of calcaneus fractures. Implant malpositioning can be avoided and the repositioning result of the articular surfaces can be monitored intraoperatively and improved where necessary. Corrective interventions can thus be avoided. An improved clinical outcome can be expected in the long term.
