About the group
A research group inside a county trauma service.
We're the orthopaedic trauma research group at Arrowhead Regional Medical Center in Colton, California — attendings, residents, and medical students who work on questions that come up while treating fractures.
What we do
Most of our projects start as a question from clinic or the OR: does this fixation hold, does this pattern heal, who isn't making it back for follow-up. We take those questions, design a study around them, and see them through — from IRB to analysis to a manuscript. The work runs across imaging, clinical outcomes, surgical technique, and population health.
Where we work
Arrowhead is the trauma center for San Bernardino County — a catchment of roughly two million people, many of whom don't show up in the registries medicine usually studies. That's part of why the work matters to us: the patients we see are the ones the literature often misses.

Getting involved
We take proposals from residents, students, and outside collaborators on a rolling basis — you bring the question, we help with design, IRB, and analysis. If you have an idea, send it over.
