Our goal is to develop a software workstation to assist in performing femoral augmentation for osteoporotic patients. The surgical procedure consists of a series of bone cement injections into the femur. The bone augmentation system features preoperative biomechanical planning to determine the most advantageous cement injection site(s) and injection protocol to increase the strength of the femur. During the surgery, we will navigate the injection device and inraoperatively reconstruct virtual models of the injected cement. The injected cement models can be used to update the injection protocol intraoperatively.
