Intraoperative 3-D imaging with ISO-C-3D and Computer Assisted Surgery in foot and ankle surgery

The clinical use of intraoperative three-dimensional imaging with a mobile motorized C-arm (ISO-C-3D) and C-ann based Computer Assisted Surgery (CAS) in foot and ankle surgery at a level one trauma center were analyzed. ISO-C-3D. The intraoperative three-dimensional imaging with the ISO-C-3D was used in 101 cases so far. In 39% of the cases, reduction and/or implant position was corrected after ISO-C-3D-scan during the same procedure. The operation was interrupted for ISO-C-3D use for 430 s on average. CAS. C-arm based CAS guided correction of posttraumatic deformities of the ankle and hindfoot region was feasible and provided very high accuracy and a faster correction process in ten cases so far. The ISO-C-3D provided important information which could not be obtained from plain films or C-arm alone. The benefit of the introduced CAS methods is high when an improved accuracy may lead to an improved clinical outcome. (c) 2005 CARS & Elsevier B.V. All rights reserved.
