Research & Publications

Research Summary

Shoulder Biomechanics: The primary focus of our research is to better understand and describe the motion of the shoulder joint in living individuals. Using a specialized non-invasive three-dimensional (3D) fluoroscopic imaging technique, we can visualize the shoulder joint in an accurate computer model. These models give insight into normal and abnormal shoulder mechanics. For example, we can assess the effects that treatments have on shoulder motion; such as total shoulder replacement, instability surgery, and rotator cuff repair. My goal in maintaining a rigorous research program is to advance and improve shoulder treatments for my patients through an objective scientific method.

Outcomes Research: We have an ongoing prospective initiative to provide quality metrics for every shoulder procedure we perform. These metrics will help patients have realistic expectations of their surgery while providing a comparison to other individuals who underwent the same procedure.

News & Events


  • Dr. Warner: Total Shoulder Replacement

    Patients with severe shoulder arthritis are unable to move their arms through the full range of motion and are unable to perform many activities of daily living. A total shoulder replacement is a proven surgical procedure to relieve pain and recover range of motion. Watch this video to learn more.
