We study how fractures get fixed.
And how patients actually recover.
Arrowhead is San Bernardino County’s trauma center. Our projects start with the fractures we treat — and ask what imaging, technique, and social factors change how they heal.
Arrowhead is the safety-net trauma center for a county of two million.
What we work on
Five areas: imaging, outcomes, surgical technique, clinical AI, and population health.
-
AI in Medicine
We build and validate machine-learning and large-language-model tools across orthopaedic trauma — detecting and classifying fractures on radiographs and CT, and testing how reliably generative AI answers patient questions.
-
Trauma Outcomes
Using our county trauma registry and multi-center data, we study what actually changes outcomes after fracture — from earlier weight-bearing after pelvic ring injuries to complication patterns in high-energy trauma.
-
Population Health
Arrowhead is a safety-net trauma center, so we study the patients other registries tend to miss: how homelessness, primary language, and substance use relate to access, treatment, and recovery after orthopaedic injury.
