The Department of Orthopedic Surgery at HCMC is a core site for the Major Extremity Trauma Research Consortium (METRC). METRC was established in 2009 with funding from the Department of Defense (DOD). It consists of a network of Level-1 trauma centers throughout the country that work along with the DOD to design and conduct multi-center clinical research studies relevant to the treatment and outcomes of orthopaedic trauma sustained in the military. The overall goal of the consortium is to produce the evidence needed to establish treatment guidelines for the optimal care of the wounded warrior and ultimately improve the clinical, functional, and quality of life outcomes of both service members and civilians who sustain high energy trauma to the extremities.
