Orthopaedic Trauma and Fracture Surgery

I am an orthopaedic trauma surgeon at Elliot Hospital, an ACS Level II trauma center, where I provide the full spectrum of adult and pediatric trauma and fracture surgery with a subspecialty interest in total shoulder replacement.

In addition to my clinical work, I write and conduct research on a field I call orthopaedic epistemology — the study of how orthopaedic knowledge is produced, measured, and interpreted, and of what our evidence can and cannot tell us.

My practice

Trauma & fracture surgery

I treat pelvic and acetabular fractures, complex pediatric injuries, fracture non-unions, and hand trauma — alongside a high volume of common injuries: wrist, hip, shoulder, and ankle fractures and tendon ruptures.

Evidence-based care

I combine the best available research with careful clinical judgment, shaped by ongoing study of medical knowledge itself — its uncertainties, and the cognitive biases that affect clinical thinking.

Independence

I have never accepted consulting fees, royalties, or payments from device companies, and I never will. Treatment decisions belong between surgeon and patient, guided by evidence and judgment alone.

My research

My work in orthopaedic epistemology examines how surgeons reason under uncertainty, the biases that shape clinical judgment, and the philosophical assumptions embedded in everyday practice.
