Introduction: Interlocking of intramedullary implants remains a challenging task of every day surgical routine and a variety of different techniques has been described in the last decades, including computer-aided techniques and using different imaging modalities. Basic techniques developed from freehand techniques and hand held guides to image intensifier mounted targeting devices and nail mounted guides. Advanced techniques range from computer navigation systems to self locking nails. [4] We present the first clinical application of CAMC, a novel AR (augmented reality) system introduced by Navab et. al. [1], and our initial experience with interlocking of intramedullary nails in phantom and cadaver studies. Augmented reality is a technique that superimposes acquired patient data e.g. intra-operative imaging data in-situ. This means the imaging data is merged spatially registered with the real view of the region of interest. This creates an intuitive and ergonomic surgical navigation system that enhances minimally invasive procedures. In this case the X-ray image and optical image share same projection geometry allowing the surgeon to work under video augmented X-ray fluoroscopic control.
