BackgroundSurgical site infections (SSI) continue to be a significant source of morbidity despite the introduction of perioperative intravenous antibiotics. Our objective was to assess the efficacy of local vancomycin powder on lowering deep SSI rates in high-energy tibial plateau and pilon fractures.Materials and methodsA retrospective review of all tibial plateau and pilon fractures treated in 2012 at our level I trauma center identified 222 patients. Of these, 107 patients sustained high-energy injuries that required staged fixation, and 93 had minimum 6 month follow-up. Ten patients received 1 gram vancomycin powder directly into the surgical wound at the time of definitive fixation, and the remaining 83 patients served as controls. SSI was defined according to criteria from the Centers for Disease Control. Demographic data, patient comorbidities, injury and treatment details, and infection details were recorded. Descriptive and comparative statistics were performed.ResultsAmongst the vancomycin powder group, 1 patient (10 %) developed a deep SSI; in the control group, 14 (16.7 %) developed deep SSI. The rate of deep SSI between the groups was not statistically significantly different (P = 1.0). The groups were statistically similar with regard to injuries, treatment, comorbidities, and infectious outcomes (P values range = 0.06–1.0).ConclusionsThe application of local vancomycin powder into surgical wounds of high-energy tibial plateau and pilon fractures did not reduce the rate of deep SSI in this retrospective review. There is a need to find effective, cheap, and widely available methods for prevention of SSI. Basic science and larger prospective clinical studies are needed to further delineate the role of local vancomycin powder as a modality to reduce deep SSI in extremity trauma.Level of evidence Level III, therapeutic.
Acute knee dislocations are an uncommon injury that can result in profound consequences if not recognized and managed appropriately on presentation. Patients presenting with knee pain in the setting of high- or low-energy trauma may have sustained a knee dislocation that spontaneously reduced. Prompt reduction of the dislocated knee and serial neurovascular examinations are paramount. Damage to the popliteal artery is a common associated injury that can be diagnosed on physical examination using ankle brachial indices (ABIs), CT angiography, or standard angiography. After reduction, patients with a normal pulse examination and an ABI ≥0.9 may be observed, with serial examination performed to document vascular status and monitor for compartment syndrome. Patients with asymmetric pulses or an ABI <0.9 in the presence of pulses may be treated urgently depending on the results of additional vascular imaging, and patients with absent pulses and clear signs of vascular compromise should be treated emergently. Some knee dislocations are not reducible and should be taken emergently to the operating room for an open reduction. Persistent joint subluxation or severe soft-tissue injuries after reduction require temporary external fixation before definitive repair or reconstruction of ligaments is performed.
Objectives:Femoral head fracture open reduction and internal fixation (ORIF) requires adequate surgical access and visualization. The purpose of this study was to objectively characterize femoral head access associated with commonly used surgical approaches. Our hypothesis was that a surgical hip dislocation (SHD) provides the greatest visualization and access to the femoral head.Methods: Ten fresh-frozen cadaveric whole-pelvis specimens (n = 20 hips) were used to compare 4 surgical approaches to the femoral head (n = 5 hips per approach): SHD, Smith-Petersen (with and without rectus release), and Hueter. After surgical exposure, standardized and calibrated digital images were captured and analyzed to determine the percent-area visualized. Three independent investigators assessed each specimen to determine surgical visualization and access to the following femoral head anatomic quadrants: anteromedial, anterolateral, posteromedial, and posterolateral. Data were analyzed for significant (P , 0.05) differences using analysis of variance (ANOVA) and Fisher exact tests.
Results:The Hueter approach provided the lowest calculated % visualization. For surgeon visualization, SHD demonstrated a significantly (P , 0.001) higher proportion of visualized anatomic landmarks compared with all other approaches. SHD provided significantly (P , 0.049) more access to the femoral head quadrants compared with all other approaches. The Hueter approach had significantly (P = 0.004) lower surgeon access compared with the Smith-Petersen with release.Conclusions: SHD provided superior visualization and access to clinically relevant femoral head anatomy compared with the Smith-Petersen with or without rectus release and Hueter approaches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
