Each year, approximately 550,000 osteoporotic patients in the US suffer from compression fractures that require pedicle screws in order to reconstruct the spine. These patients are currently given pain management treatments instead of pedicle screws, however, because osteoporotic bone isn't strong enough to hold the screws in, or prevent them from falling out. This E-Team plans to solve the problem by developing a pull-out resistant pedicle screw. The novel design, based on a vertebral compression fracture treatment known as kyphoplasty, consists of a two-part screw involving a hollow capture chamber and a threaded inner screw. The hollow chamber is inserted into the vertebral body, then the inner screw is brought through the chamber into a wet cement adhesive. As the cement cures, the stickiness of the screw is enhanced, providing greater pull-out resistance.
