Summary: Pedicle screws are commonly used to stabilize the spine. Pedicle screw failures represent a significant complication leading to re-operation and patient morbidity. This study will characterize the physiological loading pattern of pedicle screws within the vertebral body. Data from this project will provide a more complete understanding of the loading environment within the vertebrae and enable implant manufacturers and researchers to develop new and improved instrumentation, that is better suited to in vivo loading.

Findings: To date, data are currently being collected and analyzed. No significant findings are currently ready for submission as an abstract or publication, however it will be submitted to the journal Spine.
