[Intraoperative 3D imaging : Diagnostic accuracy and therapeutic benefits]

Abstract

Intraoperative 3D imaging has a marked impact on the surgical treatment of articular fractures. In theory, insufficient reduction of fracture fragments and malpositioning of implants can be corrected in the same session so that unnecessary secondary imaging and revision surgery can be avoided. Current evidence on the accuracy of 3D scans, however, relies on heterogeneous preclinical data and must be interpreted with caution. Every fourth 3D scan seems to lead to a repositioning of fracture fragments or implants, despite unproven sensitivity and specificity. The interaction between diagnostic accuracy and therapeutic consequences needs exploration before any conclusions on the (additional) benefits of intraoperative 3D imaging can be drawn.
