Improved outcomes following the early fixation of long-bone fractures were reported. Early fixation was associated with a decrease in prevalence of acute respiratory distress syndrome (ARDS). Early treatment of femur fractures led to fewer days in the intensive care unit and reduced femur venting. In 1989, a prospective, randomized trial with early treatment of femur fracture was halted due to death in the delayed-treatment group. A 1994 multicenter study in which 676 patients whose femur or bilateral tibia fracture was stabilized within 48 hours of the injury were compared with 906 patients from the Major Trauma Outcome Study determined that ETC reduced mortality.\u003C\/p\u003E\n         \u003Cp id=\u0022p-4\u0022\u003EIn 1993, the Hannover group reported that ETC in patients with severe pulmonary injuries had worse outcomes than in patients who had delayed definitive fracture fixation. Immediate care of all fractures is not always beneficial when a patient\u0027s condition is unstable. In such cases, damage control is practiced. In damage control, acute stabilization is limited to major fractures to control blood loss and improve mobilization. It may be better to delay definitive fixation for some patients, such as those who may be predisposed to an adverse pulmonary outcome. The presence of severe thoracic injury in the absence or presence of fracture is a risk factor for ARDS. However, delaying surgery after major trauma may worsen systematic inflammatory response syndrome (SIRS), which can prelude ARDS and multiple organ failure.\u003C\/p\u003E\n         \u003Cp id=\u0022p-5\u0022\u003EPatients can be assessed for physiologic markers of trauma, such as elevated lactate, to determine whether to use ETC or damage control. One option is to provide external support of fracture injuries, such as lower-extremity long-bone fractures and pelvic injuries, while more pressing life-threatening injuries are addressed [Scalea TM et al. \u003Cem\u003EJ Trauma.\u003C\/em\u003E 2000].\u003C\/p\u003E\n      \u003C\/div\u003E\u003Cdiv class=\u0022section\u0022 id=\u0022sec-2\u0022\u003E\n         \u003Ch2 class=\u0022\u0022\u003EMITOCHONDRIAL DAMPs AND INFLAMMATION AFTER TRAUMA\u003C\/h2\u003E\n         \u003Cp id=\u0022p-6\u0022\u003ECarl J. Hauser, MD, Beth Israel Deaconess Medical Center, Boston, Massachusetts, USA, discussed post-trauma damage-associated molecular patterns (DAMPs) and SIRS. SIRS is a response to trauma and to any insult to the body (eg, infection, burns, and surgery).\u003C\/p\u003E\n         \u003Cp id=\u0022p-7\u0022\u003EIn the setting of infection, part of the response involves the recognition of pathogen-associated molecular patterns (PAMPs). In the absence of infection that occurs in mechanical damage, toxin-mediated damage, and shock, DAMPs are operative. Both patterns activate proteins called pattern recognition receptors or Toll-like receptors, which start the innate immune responses in a complex system of communication involving multiple cell proteins. Key proteins are tumor necrosis factor and interleukin (IL)-1.\u003C\/p\u003E\n         \u003Cp id=\u0022p-8\u0022\u003EMitochondrial DNA have been implicated as DAMPs. Mitochondria once were free-living bacteria that evolved a symbiotic relationship with eukaryotic cells precluding the process of becoming cell organelles. Cell damage that involves mitochondria causes the release of mitochondrial DNA, which triggers injury-related inflammatory responses [Zhang Q et al. \u003Cem\u003ENature.\u003C\/em\u003E 2010]. Mitochondrial formyl peptides have also been implicated as DAMPs [Raoof M et al. \u003Cem\u003EJ Trauma.\u003C\/em\u003E 2010].\u003C\/p\u003E\n      \u003C\/div\u003E\u003Cdiv class=\u0022section\u0022 id=\u0022sec-3\u0022\u003E\n         \u003Ch2 class=\u0022\u0022\u003ESYSTEMIC RESPONSE TO INJURY IN PATIENTS WITH POLYTRAUMA\u003C\/h2\u003E\n         \u003Cp id=\u0022p-9\u0022\u003EHans-Christoph Pape, MD, RWTH Aachen University Medical Center, Aachen, Germany, discussed the systemic response to injury in patients with multiple injuries.

Damage control is affected by a number of variables, including those related to the patient, injury, and treatment. Patient variables include age, medical comorbidities, the bone that is fractured, and the nature of the treatment. Damage control is subject to serious, even life-threatening consequences of inflammation. The type and timing of an orthopaedic procedure can influence patient outcome [Morshed S et al. \u003Cem\u003EJ Bone Joint Surg Am.\u003C\/em\u003E 2009], with a subsequent exacerbated immune response causing organ failure distant from the affected body site.\u003C\/p\u003E\n         \u003Cp id=\u0022p-15\u0022\u003EWhether the risk of ARDS can be modified remains an open question, as is the optimal timing of some treatments and the validation and application of valuable risk markers in the operating room.
