Benefits of early stabilization of femoral shaft fractures, in mitigation of pulmonary and other complications, have been recognized over the past decades. Investigation into the appropriate level of resuscitation, and other measures of readiness for definitive fixation, versus a damage control strategy have been ongoing. These principles are now being applied to fractures of the thoracolumbar spine, pelvis, and acetabulum. Systems of trauma care are evolving to encompass attention to expeditious and safe management of not only multiply injured patients with these major fractures, but also definitive care for hip and periprosthetic fractures, which pose a similar burden of patient recumbency until stabilized. Future directions regarding refinement of patient resuscitation, assessment, and treatment are anticipated, as is the potential for data sharing and registries in enhancing trauma system functionality.

Purpose. In patients with multiple trauma delayed fracture healing is often diagnosed, but the pathomechanisms are not well known yet. The purpose of the study is to evaluate the effect of a severe hemorrhagic shock on fracture healing in a murine model. Methods. 10 male C57BL/6N mice per group (Fx, TH, THFx, Sham) and point in time were used. The Fx-group received an osteotomy after implantation of a fixateur extern. The TH-group got a pressure controlled hemorrhagic shock with a mean arterial blood pressure of 35 mmHg over 90 minutes.
The best time for definitive orthopaedic care is often unclear
in patients with multiple injuries. The objective of this study
was make a prospective assessment of the safety of our early appropriate
care (EAC) strategy and to evaluate the potential benefit of additional
laboratory data to determine readiness for surgery. A cohort of 335 patients with fractures of the pelvis, acetabulum,
femur, or spine were included. Patients underwent definitive fixation
within 36 hours if one of the following three parameters were met:
lactate <
4.0 mmol/L; pH ≥ 7.25; or base excess (BE) ≥ -5.5 mmol/L.
If all three parameters were met, resuscitation was designated full
protocol resuscitation (FPR). If less than all three parameters
were met, it was designated an incomplete protocol resuscitation
(IPR). Complications were assessed by an independent adjudication
committee and included infection; sepsis; PE/DVT; organ failure;
pneumonia, and acute respiratory distress syndrome (ARDS). Aims
Patients and Methods
External fixation is widely used in orthopaedic
and trauma surgery. Infections around pin or wire sites, which are usually
localised, non-invasive, and are easily managed, are common. Occasionally,
more serious invasive complications such as necrotising fasciitis
(NF) and toxic shock syndrome (TSS) may occur. We retrospectively reviewed all patients who underwent external
fixation between 1997 and 2012 in our limb lengthening and reconstruction
programme. A total of eight patients (seven female and one male)
with a mean age of 20 years (5 to 45) in which pin/wire track infections
became limb- or life-threatening were identified. Of these, four
were due to TSS and four to NF. Their management is described. A
satisfactory outcome was obtained with early diagnosis and aggressive
medical and surgical treatment. Clinicians caring for patients who have external fixation and
in whom infection has developed should be aware of the possibility
of these more serious complications. Early diagnosis and aggressive
treatment are required in order to obtain a satisfactory outcome. Cite this article:
We describe the impact of a targeted performance
improvement programme and the associated performance improvement
interventions, on mortality rates, error rates and process of care
for haemodynamically unstable patients with pelvic fractures. Clinical
care and performance improvement data for 185 adult patients with exsanguinating
pelvic trauma presenting to a United Kingdom Major Trauma Centre
between January 2007 and January 2011 were analysed with univariate
and multivariate regression and compared with National data. In
total 62 patients (34%) died from their injuries and opportunities
for improved care were identified in one third of deaths. Three major interventions were introduced during the study period
in response to the findings. These were a massive haemorrhage protocol,
a decision-making algorithm and employment of specialist pelvic
orthopaedic surgeons. Interventions which improved performance were
associated with an annual reduction in mortality (odds ratio 0.64
(95% confidence interval (CI) 0.44 to 0.93), p = 0.02), a reduction
in error rates (p = 0.024) and significant improvements in the targeted
processes of care. Exsanguinating patients with pelvic trauma are
complex to manage and are associated with high mortality rates;
implementation of a targeted performance improvement programme achieved
sustained improvements in mortality, error rates and trauma care
in this group of severely injured patients. Cite this article:
Local corticosteroid infiltration is a common practice of treatment
for lateral epicondylitis. In recent studies no statistically significant
or clinically relevant results in favour of corticosteroid injections
were found. The injection of autologous blood has been reported
to be effective for both intermediate and long-term outcomes. It
is hypothesised that blood contains growth factors, which induce
the healing cascade. A total of 60 patients were included in this prospective randomised
study: 30 patients received 2 ml autologous blood drawn from contralateral
upper limb vein + 1 ml 0.5% bupivacaine, and 30 patients received
2 ml local corticosteroid + 1 ml 0.5% bupivacaine at the lateral
epicondyle. Outcome was measured using a pain score and Nirschl
staging of lateral epicondylitis. Follow-up was continued for total
of six months, with assessment at one week, four weeks, 12 weeks
and six months.Objectives
Methods
There have been many advances in the resuscitation
and early management of patients with severe injuries during the
last decade. These have come about as a result of the reorganisation
of civilian trauma services in countries such as Germany, Australia
and the United States, where the development of trauma systems has
allowed a concentration of expertise and research. The continuing
conflicts in the Middle East have also generated a significant increase
in expertise in the management of severe injuries, and soldiers
now survive injuries that would have been fatal in previous wars.
This military experience is being translated into civilian practice. The aim of this paper is to give orthopaedic surgeons a practical,
evidence-based guide to the current management of patients with
severe, multiple injuries. It must be emphasised that this depends
upon the expertise, experience and facilities available within the
local health-care system, and that the proposed guidelines will
inevitably have to be adapted to suit the local resources.
The beneficial effects of therapeutic hypothermia have been capitalised upon in fields such as cardiac surgery for several decades. Hypothermia not only slows metabolism and consumption of metabolic substrates, but also confers cellular protection against ischaemia and reperfusion. Hypothermia has historically been considered as something to avoid in trauma casualties, with coagulopathy being the main concern. There is now increasing evidence for the role of controlled therapeutic hypothermia in trauma, particularly improved functional outcomes following brain injury and the utility of ‘suspended animation’ or ‘emergency preservation’ in the resuscitation of severe haemorrhagic shock. With the ongoing ‘Eurotherm’ trial of hypothermia in the treatment of traumatic brain injury, and the imminent launch of the ‘Emergency Preservation and
The types of explosive devices used in warfare
and the pattern of war wounds have changed in recent years. There has,
for instance, been a considerable increase in high amputation of
the lower limb and unsalvageable leg injuries combined with pelvic
trauma. The conflicts in Iraq and Afghanistan prompted the Department
of Military Surgery and Trauma in the United Kingdom to establish
working groups to promote the development of best practice and act
as a focus for research. In this review, we present lessons learnt in the initial care
of military personnel sustaining major orthopaedic trauma in the
Middle East.
High energy fractures of the pelvis are a challenging problem both in the immediate post-injury phase and later when definitive fixation is undertaken. No single management algorithm can be applied because of associated injuries and the wide variety of trauma systems that have evolved around the world. Initial management is aimed at saving life and this is most likely to be achieved with an approach that seeks to identify and treat life-threatening injuries in order of priority. Early mortality after a pelvic fracture is most commonly due to major haemorrhage or catastrophic brain injury. In this article we review the role of pelvic binders, angiographic embolisation, pelvic packing, early internal fixation and blood transfusion with regard to controlling haemorrhage. Definitive fixation seeks to prevent deformity and reduce complications. We believe this should be undertaken by specialist surgeons in a hospital resourced, equipped and staffed to manage the whole spectrum of major trauma. We describe the most common modes of internal fixation by injury type and review the factors that influence delayed mortality, adverse functional outcome, sexual dysfunction and venous thromboembolism.
This study assessed whether undergraduate performance improved following the introduction in 2006 of a musculoskeletal teaching programme lasting for seven weeks. Different methods were used to deliver knowledge and skills in trauma and orthopaedic surgery, rheumatology and allied specialties. The programme combined four main elements: traditional firm-based teaching, weekly plenary sessions, a task-based workbook and additional specialist clinics. The block of 139 students who attended in its first year were assessed using a multiple choice question examination just before their final examinations in 2008. They showed a 6% improvement in performance over a control group of 130 students assessed in 2005 before the programme had commenced. There was no difference in performance between the students assessed in 2005 and a second group of 46 students from 2008 who did not attend the new teaching programme. Performance was improved by providing more focused musculoskeletal training using available resources, as well as increasing the length of the programme.
This study was undertaken to assess the contribution of fat embolism (FE) to the development of acute lung injury in the presence of resuscitated hemorrhagic shock. Twenty-seven NZW rabbits were randomly assigned into four groups: resuscitated hemorrhagic shock and FE (HR/FE), resuscitated hemorrhagic shock, FE, and control. FE was induced via intramedullary femoral canal pressurization using a 1–1.5 ml bone cement injection. Only HR/FE animals displayed significant proinflammatory cytokine release as compared to controls. These findings suggest that the combination of resuscitated shock with FE initiates an inflammatory response, which may lead to the development of fat embolism syndrome. The objective of this study was to assess the contribution of fat embolism caused by intramedullary femoral canal pressurization to the development of acute lung injury in the presence of resuscitated hemorrhagic shock. Only the animals that underwent resuscitated shock and fat embolism displayed amplified BALF proinflammatory cytokine expression. These findings suggest that the combination of resuscitated shock with fat embolism initiates an inflammatory response, which may play a role in the development of fat embolism syndrome. Only HR/FE BALF IL-8 and MCP-1 levels were significantly higher than controls (0.72 ng/ml vs. 0.26ng/ ml, p=0.03; 18.3 ng/ml vs. 2.0 ng/ml, p=0.01, respectively). Twenty-seven NZW rabbits were randomly assigned into four groups: resuscitated hemorrhagic shock + fat embolism (HR/FE), resuscitated hemorrhagic shock (HR), fat embolism (FE), and control. Shock was induced via carotid bleeding for one-hour prior to resuscitation. For FE induction, the intramedullary cavity was drilled, reamed and pressurized with a 1–1.5 ml bone cement injection. Four hours later, postmortem bronchoalveolar lavage was performed through the right mainstem bronchus. Analyses of bronchoalveolar lavage fluid (BALF) of interleukin-8 (IL-8) and monocyte chemoattractant protein-1 (MCP-1) were carried out in triplicate and blinded fashion using the ELISA technique. Our findings suggest that FE by itself does not initiate inflammatory lung injury, as there were no apparent differences between the control and FE cytokine levels. Only the HR/FE animals revealed elevated levels of pro-inflammatory cytokines in BALF. These findings are in agreement with our previous results, which displayed neutrophil activation only in the HR/FE group.
This study was undertaken to assess the contribution of pulmonary fat embolism caused by intramedullary femoral canal pressurization to the development of acute lung injury in the presence of resuscitated hemorrhagic shock. Twenty-seven NZW rabbits were randomly assigned into one of four groups: resuscitated hemorrhagic shock and fat embolism, resuscitated hemorrhagic shock, fat embolism, and control. Fat embolism was induced via intramedullary cavity with a 1–1.5 ml bone cement injection. Only the animals that underwent resuscitated shock and fat embolism displayed amplified neutrophil activation and alveolar infiltration. These findings suggest that the combination of resuscitated shock with fat embolism initiates an inflammatory response, which may play a role in the development of fat embolism syndrome. The objective of this study was to assess the contribution of pulmonary fat embolism caused by intramedullary femoral canal pressurization to the development of acute lung injury in the presence of resuscitated hemorrhagic shock. Only the animals that underwent resuscitated shock and fat embolism displayed amplified neutrophil activation and alveolar infiltration. These findings suggest that the combination of resuscitated shock with fat embolism initiates an inflammatory response, which may play a role in the development of fat embolism syndrome. CD11b mean channel florescence was only significantly elevated in the HR/FE group at two and four hours post knee manipulation. Moreover, greater infiltration of alveoli by leukocytes was only significantly higher in the HR/FE group as compared to controls. Twenty-seven NZW rabbits were randomly assigned into one of four groups: resuscitated hemorrhagic shock + fat embolism (HR/FE), resuscitated hemorrhagic shock (HR), fat embolism (FE), and control. Hypovolemic shock was induced via carotid bleeding for one-hour prior to resuscitation. For fat embolism induction, the intramedullary cavity was drilled, reamed and pressurized with a 1–1.5 ml bone cement injection. For evaluation of neutrophil activation, blood was stained with antibodies against CD45 and CD11b and analyzed with a flow cytometer. Animals were mechanically ventilated for four hours post surgical closure. Postmortem thoracotomy was performed, and three stratified random blocks of each lung were processed for histological examination. Our findings suggest that FE by itself does not cause lung injury, as there were no apparent differences between the control and FE animals. Only the HR/FE animals revealed a higher number of infiltrating neutrophils into alveolar spaces and greater neutrophil activation.
Aims: Pharmacological modulation of skeletal muscle reperfusion injury after trauma associated ischaemia may improve limb salvage rates and prevent the associated systemic sequelae.
Ischaemia threatening an injured limb gives rise to the syndrome of pain, pallor, paralysis, and pulselessness. It is due to arterial injury by laceration, compression, intra-mural rupture or contusion, or to arterial spasm with or without demonstrable local arterial damage. The differentiation of spasm without local injury from organic obstruction is not possible by clinical methods. The suggested plan of treatment and of management is:. 1. General systemic investigation (blood-pressure, blood-count, coagulation time, etc.). 2. Removal of all external pressure. 3.
