• Major Extremity Trauma• Research Consortium• Improving outcomes through collaborative

research

METRC Studies

• BIOBURDEN- assessing bacterial load in open tibia fractures-Currently Enrolling

• OUTLET- Outcome after severe distal tibia/hindfoot fractures- Currently Enrolling

• POvIV- Randomized study comparing PO vs IV abx in acute infections after orif- Currently Enrolling (Identify Patients if seen in clinic)

• OXYGEN- effect of high vs low O2 conc periop for orif fxs- (Awaiting IRB approval)

METRC Studies

• TAOS- Comparing BKA techniques- Burgess vs Ertl (In preparation for IRB approval)

• STREAM- PROMIS based IPAD study to evaluate for depression in OUTLET patients

Selected Other Trauma Division Clinical Trials

• Local antibiotics to prevent wound infection– IRB Review

• Administration of abx in the field for open fxs– Drafting protocols

• Tibia Fracture database

Successful CollaborationVolumetric Muscle Loss

• The Problem– Severe musculoskeletal injuries often associated

with loss of muscle– Surrounding muscle can hypertrophy but does not

fully compensate– If complete loss of muscle unit- limited options to

recover function

VML

• Is there a way to replace lost muscle with scaffold to allow regeneration of new/functional muscle?

• KeraNetics is an advanced biomaterials company focused on creating keratin-based products for therapeutic and regenerative medical applications.(from their website)

• - Developed Keratin Gel scaffold which can serve as void filler and potentially as carrier for molecules to assist with muscle growth

• Basic Science work ongoing• Animal study planned• Needed clinical trial plan to assess safety• Short time frame due to grant deadlines

VML

• Limited clinical data• Big issue in Wounded Warriors• Utilized data from UVA studies on muscle to

form materials/methods• Plan for 5 patient trial• 25-30 cc VML in anterior tibialis after injury
