Introduction Analysis of injuries during military operations has focused on those related to combat. Non-combat complaints have received less attention, despite the need for many troops to be evacuated for non-battle illnesses in Iraq. This study aims to further characterize the disease and non-battle injuries (DNBIs) seen at a tertiary combat hospital and to describe the types of procedures and medications used in the management of these cases. METHODS: In this observational study, patients were enrolled from a convenience sample with non-combat-related diseases and injuries who were evaluated in the emergency department (ED) of a US military tertiary hospital in Iraq from 2007-2008...

BACKGROUND: Each year it is estimated in the United States an approximate of 8 million fractures; 5 to 10% develop delayed union or absence of periosteal new bone. There are several factors that can cause delay in fracture healing, among the well known, is the use of prophylactic antithrombotic therapy for deep vein thrombosis (DVT). DVT appears in 40 to 60% of the patients undergoing orthopedic surgery without prophylactic antithrombotic therapy. The goal of this study was to assess whether there is a difference in time of bone healing in lower limb fractures (femur and tibia) comparing rivaroxaban to enoxaparin as the prophylactic antithrombotic management...

Finding new strategies to counteract periprosthetic infection and implant failure is a main target in orthopedics. Staphylococcus aureus, the leading etiologic agent of orthopedic implant infections, is able to enter and kill osteoblasts, to stimulate pro-inflammatory chemokine secretion, to recruit osteoclasts, and to cause inflammatory osteolysis. Moreover, by entering eukaryotic cells, staphylococci hide from the host immune defenses and shelter from the extracellular antibiotics. Thus, infection persists, inflammation thrives, and a highly destructive osteomyelitis occurs around the implant...

The characteristic trait of metallosis is the presence of tissue staining. Analyzing explanted revision hardware from spine surgeries and performing ICPMS/AES analysis on removed tissue samples, a clinically relevant definition for metallosis may be developed. Results of the analysis identified hardware fretting wear and corrosion, and ICP-MS/AES analysis identified elevated metal ion concentrations in all cases. This supports the hypothesis that corrosion may be linked to poor health outcomes and potential need for revision surgery...

Cadaveric simulation models allow researchers to study native tissues in situ. However, as tests are conducted using donor specimens with unmatched kinematics, techniques that impose population average motions are subject to deviation from true physiologic conditions. This study aimed to identify factors which explain the kinetic variability observed during robotic simulations of a single human gait motion using a sample of human cadaver knees. Twelve human cadaver limbs (58 ± 16 years) were subjected to tibiofemoral geometrical analysis and cyclical stiffness testing in each anatomical degree of freedom...
