Filter by:Current spine procedures can suffer from a variety of complications resulting in a high incidence (up to 55%) of misplaced screws and implants. This can lead to devastating clinical consequences, including neurologic and vascular injury, and extensive physical, mental, and economic damage. Surgical navigation has a great potential to reduce these risks through accurate guidance; however present technologies rely on intraoperative imaging that uses ionizing radiation (e.g. computed tomography, or fluoroscopy), which limits surgical anatomy registration updates to less than 3-4 time points during surgery. They also require cumbersome and lengthy set-up and registration of fiducial markers and have limited abilities to account for motion that occurs during surgery and patient positioning. Therefore, the investigators propose a real-time intraoperative optical topographical imaging based surgical guidance system capable of accurately guiding the placement of implanted devices such as screws.
For a significant number of patients suffering from back pain, even basic daily activities become impossible. It is at this time that spinal surgery becomes necessary in order to improve the patient's quality of life. To combat these symptoms, surgical implants (e.g. pedicle screws, rods, etc.) are used to aid in stabilizing and correcting the deformities of the spine, particularly after spinal decompression. The clinical need for spinal surgery is compounded by current and continuing demographic trends. As the general population continues to age, the number of orthopaedic surgical interventions is expected to rise drastically. Therefore, a significant opportunity exists for the implementation of surgical guidance technologies, for orthopaedic procedures, to combat this overwhelming health care burden.
