Osteoporotic Bone Augmentation

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.

Approach

This image guided percutaneous femoroplasty system can be divided into three main phases:

  1. Planning
  2. Navigation
  3. Intraoperative Evaluation

Status and Results to Date

For preoperative evaluation we conduct finite element analysis of the biomechanics of the femur from CT image sets.For intraoperative evaluation we are reconstructing 3D model of the bone cement from 2D X-ray projections. During intraoperative evaluation we optimize registration estimates with multi-image optimization
