Condition(s) targeted: Surgical Site Infection

Intervention: Vancomycin powder (Drug)

Phase: N/A

Status: Recruiting

Sponsored by: Vanderbilt University


Despite the use of prophylactic systemic antibiotics and improved surgical technique, surgical site infections remain a serious concern. The incidence of deep infection after spine surgery has been lowered with systemic antibiotics, yet after instrumented fusion for traumatic injuries infection rates remain as high as 10%. The impact on patients and cost of treating such infections is profound. With diminishing healthcare dollars and policy that refuses to reimburse for postoperative infections, it is critical that physicians and hospital systems seek out cost effective ways of decreasing postoperative infections. Local delivery of antibiotics into the surgical site have been found to significantly decrease infection rates in those undergoing posterior spine fusion for traumatic injuries as studied in a retrospective manner by the investigators of this grant. In this proposal the investigators will prospectively randomize patients undergoing posterior spinal stabilization for traumatic injuries into either receiving vancomycin powder into the surgical site (treatment) versus not receiving vancomycin powder (control) and subsequently follow infection rate, complications, and cost of care. The investigator's hypothesis is that i) vancomycin powder will decrease infection rates ii) have no systemic toxicity iii) and be a cost saving advancement in the safety of delivering spine surgical care.
