Resident research

Geisinger Musculoskeletal Institute Research Team

As a resident, you’ll be encouraged to take advantage of the tremendous research opportunities and research support offered through the devoted MSK research team. Assistance is available for developing ideas, obtaining IRB approval, pursuing funding, statistical analysis and submitting final papers to national meetings and peer-reviewed journals.

In addition to basic science and clinical research, the research team has been driving groundbreaking epidemiologic and outcomes-based research in the field of orthopaedic surgery. Research is further facilitated through the funding of three full-time research fellows in orthopaedic upper extremity research, orthopaedic trauma and adult reconstruction.

You’ll be encouraged to complete a junior project (case report or case series) and a senior project (cohort study or clinical trial). Generous financial support for resident travel to local and national presentations is provided from departmental funds and the office of Graduate Medical Education.
