Our null hypothesis is that micromotion tibial intramedullary fixation (IMFN) does not impact union or complication rates when compared to standard of care treatment with non-micromotion tibial nail fixation. There are no current or past randomized controlled trials comparing these fixation techniques to one another. There is good data supporting both the use of intramedullary fixation for tibial fractures alone, and in high-risk patient populations (open fractures, GSW tibial fractures). However, the effectiveness of these methods with respect to each other has never been investigated. The knowledge gained will allow us to potentially influence and adapt protocols to treat this patient population. Additionally, resources available at our institution provide a supportive framework with which to maintain contact with patients after hospital discharge. These key factors will allow us to perform a robust analysis of this population, to include outcomes measures of function and complications. With much of the limited existing literature on tibial nails being in very defined populations, without a strong comparison group there is no clear guidance on when the use of a micromotion device is indicated. Our approach to randomize our patients will reduce the bias that exists in the current literature and provide a robust spectrum of injuries to sub analyze and compare. Objectives Primary Objective Compare post-operative union rates in tibial shaft patients treated with 2 types of intramedullary rod fixation devices. Secondary Objective(s) Compare complication rates, patient reported outcomes, range of motion, pain and radiographic/sonographic outcomes in patients treated with tibial nails.

Introduction: Fluid overload and systemic inflammation are major contributors to postoperative complications in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). Objective: To evaluate the effects of blood washing with methylene blue during zero-balance ultrafiltration (ZBUF) on fluid overload and systemic inflammatory response. Methodology: Fluid status was assessed using the InBody S10 precision bioimpedance device, measuring extracellular water (ECW), total body water (TBW), intracellular water (ICW), and the ECW/TBW ratio. Pulmonary congestion and intravascular volume were evaluated separately using a Philips Lumify S4-1 transducer with a Samsung tablet. Pulmonary congestion was confirmed by the presence of B-lines on lung ultrasound. Intravascular volume was assessed via the inferior vena cava (IVC) distensibility index (DI) during mechanical ventilation and collapsibility index (CI) during spontaneous breathing. Inflammatory cytokine levels were measured using a Luminex xMAP-based multiplex immunoassay.
