Spine Care Center Research

The University's Spine Care Center is actively involved in clinical research. This research helps to further the understanding of spinal cord injuries and disorders, which helps to improve the diagnostic and treatment capabilities available.

Several Center members also review and publish extensively in peer-reviewed journals such as Spine, The Journal of Orthopaedic Trauma, Orthopaedics and The Journal of Trauma. Below, please find publications in peer-reviewed journals by our clinical and research faculty since 2010. Click the title for a link to the article's abstract.
