Blaine A. Christiansen

Clinical Interests

My primary research interest is the adaptation of musculoskeletal tissues to the mechanical environment, injury, or disease.  The musculoskeletal system has an innate ability to repair and optimize itself based on the mechanical demands placed on it. 

By studying this adaptation, we are able to uncover underlying mechanisms that contribute to diseases such as osteoporosis and osteoarthritis. 

My research primarily utilizes small animal models of injury, mechanical loading or unloading.  Musculoskeletal adaptation is quantified in these models using advanced imaging techniques, histology, and mechanical testing. 

My current projects include investigation of biomechanical and biological mechanisms that contribute to the development of post-traumatic osteoarthritis, and the effect of peripheral nerve function on bone metabolism and bone adaptation to mechanical loading or fracture.
