Orthopaedic Trauma Research During Fellowship

Research During Fellowship

Each fellow is required to complete one research project from idea inception to manuscript submission. A structured research curriculum with associated timeline and dedicated meetings built into the academic calendar ensures success. Fellows work with the program director and faculty mentors to: develop a scientific question; generate a hypothesis; write a protocol to be approved by the Internal Review Board; perform data collection and analysis; submit an abstract to a national meeting; present the project at the year-end fellow/resident graduation, Orthopaedic Surgery Department Garceau-Wray Lectureship; and submit a manuscript.

Ongoing research and grant funding at IU School of Medicine has led to employment of full-time research coordinators and research assistants allocated only to the orthopaedic trauma service. This improves the efficiency of the research projects and provides the fellows with administrative support to complete projects in a timely fashion.

As the director of the research program, Dr. Todd McKinley has been successful in securing over $10 million in grant funding to support the program.

Orthopaedic Trauma Collaboration

Indiana University Health Methodist Hospital is an active member of METRC, the Major Extremity Trauma and Rehabilitation Consortium, serving as one of six "anchor" sites. A list of METRC investigations can be found at https://www.metrc.org/research/. Additionally, the department has many established national collaborations.

Ongoing Clinical Studies

  • PRECISE
    To evaluate the use of precision methods that quantify injury and response to injury to predict how short-term clinical outcomes are affected by initial and staged orthopaedic interventions in multiple injured patients who sustain major orthopaedic trauma.
  • WINDOWS
    Precision medicine approach based on discrete time windows for predicting outcomes of polytrauma patients. The overarching goal of this project is to deliver precision medicine tools that will predict each patient’s risk for adverse outcomes using patient-specific metrics that quantify genetic and demographic signatures combined with individualized injury and injury response signals to accurately stratify expected clinical trajectories.
  • Nonunions
    Multiple projects evaluating various aspects of nonunions. Are all nonunions infected? Do nonunions need to be cultured? Can we predict nonunion early after fracture via biomarker signals obtained through serial sampling of peripheral blood? We also work with a consortium developing a large nonunion database allowing more questions to be asked by virtue of being less limited by sample size.
  • Amobarbital
    Phase I/II clinical trial investigating the use of Amobarbital in mitigating PTOA development after pilon fractures.
  • Porcine Model of Composite Limb Trauma
    Controlled segmental bone defects and volumetric muscle loss injuries are created in pig tibias. Bone healing and functional muscle tests, serum investigation of the immunologic response to trauma, and local tissue analyses of healing are performed to better understand muscle-bone interactions and potential treatments for these difficult to manage orthopaedic injuries.
