There are concerns with regard to the physiological effects of reamed intramedullary femoral fracture stabilisation in patients who have received a pulmonary injury. This large animal study used invasive monitoring techniques to obtain sensitive cardiopulmonary measurements and compared the responses to Early Total Care (reamed intramedullary femoral fracture fixation) to Damage Control Orthopaedics (external fixation), after the induction of acute lung injury. We hypothesised a greater cardiopulmonary response to intramedullary fracture fixation. Acute lung injury (PaO2/FiO2 < 200 mmHg) was induced in 12 invasively monitored and terminally anaesthetised male sheep via the infusion of oleic acid into the right atrium. Each animal underwent surgical femoral osteotomy and fixation with either reamed intramedullary (n=6) or external fixation (n=6). Simultaneous haemodynamic and arterial blood-gas measurements were recorded at baseline and at 5, 30 and 60 minutes after fracture stabilisation.Purpose

Antibiotic prophylaxis plays an important role in minimizing surgical site infections as well as other nosocomial peri-operative infections in orthopaedic trauma patients. Pre-operative prophylaxis has been shown to be efficacious, but the role and duration of post-operative prophylaxis remains controversial. The goal of this study was to assess whether patients receive their antibiotic prophylaxis as prescribed. What dose and duration of antibiotics are typically ordered, what patients actually receive, and factors causing the ordered antibiotic regime to be altered were also investigated. This study did not investigate infection rates or the efficacy of various antibiotic prophylactic regimes. This study presents data collected through a retrospective chart review of 205 patients treated surgically for a closed fracture at one institution. A national survey was also distributed to all surgeon members of the Canadian Orthopaedic Trauma Society (COTS) concerning antibiotic prophylaxis in the setting of surgical treatment for closed fractures.Purpose
