The intraoperative application of augmented reality (AR) has so far mainly taken place in the field of endoscopy. Here, the camera image of the endoscope was augmented by computer graphics derived mostly from preoperative imaging. Due to the complex setup and operation of the devices, they have not yet become part of routine clinical practice. ⋯ It combines its video live stream geometrically correct with the acquired X-ray. The clinical application of the device in 43 cases showed the strengths of the device in positioning for X-ray acquisition, incision placement, K-wire placement, and instrument guidance. With its new function and the easy integration into the OR workflow of any procedure that requires X-ray imaging, the CamC has the potential to become the first widely used AR technology for orthopedic and trauma surgery.

The advantages of flat panel detector technology with X-ray sensitive semiconductor technology has increasingly gained acceptance in the inpatient setting for diagnostic X-ray imaging in recent years and has replaced conventional X-ray films. For intraoperative imaging C-arms, not least for cost reasons, are still based on conventional image intensifier technology. ⋯ Direct digital imaging with improved image quality, with a possible reduction in radiation dose while at the same time enlarging the image field, can affect the procedural quality of surgery. A return on investment can be achieved in part by saving time and avoiding additional postoperative imaging.

Diffusion tensor (DT) imaging-based fiber tracking is a noninvasive magnetic resonance technique that can delineate the course of white matter fibers. ⋯ DT imaging-based fiber tracking is a reliable and accurate method for mapping the course of subcortical PTs. Fiber tracking and intraoperative MEPs were useful for preserving motor function in patients with gliomas near the PT.

Apolipoprotein E e4 allele does not increase the risk of early postoperative delirium after major surgery.
A relationship between patients with a genetic predisposition to and those who develop postoperative delirium has not been yet determined. The aim of this study was to determine whether there is an association between apolipoprotein E epsilon 4 allele (APOE4) and delirium after major surgery. ⋯ Apolipoprotein e4 carrier status was not associated with an increased risk for early postoperative delirium. Age, congestive heart failure, and emergency surgery were independent risk factors for the development of delirium after major surgery.
