Research

The Reno Orthopedic Fracture Care & Trauma team has consistently conducted research studies that investigate methods for optimizing patient care.

The Reno Orthopedic Clinic is the distinct leader in northern Nevada for conducting and publishing orthopedic research dedicated to orthopedic disorders. Annually the team at The Center for Fracture Care & Trauma Care presents their scientific findings at national orthopedic conferences and/or publishes the findings in peer-reviewed journals. This firm commitment to the future development of orthopedic science results in an orthopedic practice that offers state-of-the-art, evidence-based, best-practice orthopedic care for our fracture patients.

Our Trauma physicians have over 100 peer reviewed publications. The following research studies have been published in professional journals or textbooks:
