Abstract: IntraOsteal UltraSound (IOUS) is the use of acoustical energy to facilitate “real-time” manipulation and navigation of a device for intraosseous placement of synthetic or biologic implants and to diagnose the condition of the tissue into which the implant is being placed. Representative applications include placement of synthetic or biologic implants, such as bone screws, through vertebral pedicles during spinal fusion surgery. Devices for use in the placement of the implants include a means for creating a lumen or channel into the bone at the desired site in combination with a probe for providing realtime feedback of differences in density of the tissue, typically differences in acoustical impedance between cancellous and cortical bone. The devices will also typically include means for monitoring the feedback such as a screen creating an image for the surgeon as he creates the channel, and/or an audible signal which different tissues are present. The system can also be used for diagnostic applications.
