Background: Pelvic fractures are frecuently associated with massive intrapelvic bleeding from venous or arterial sources. Different treatment algorithms has been proposed in order to stablish early control of haemorragic sites, mostly based on external fixation/angiography. The aim of present study was to evaluate the clinical evolution of 70 pelvic fractures with uncontrolled hypotension treated with combined ex fix/angio based on fracture pattern.

Materials and methods: Case serie . We analyzed a serie of patients admitted at our center between 1994 and 2004 with pelvic fracture and haemodinamic instability , treated by the same algorithm. Decision-making for the first treatment(angio vs external fixation) were based on the type of pelvic fracture. Patients was considered unstable if PAS was less than 90mmHg or the patients needs more than two blood products replacement in first 24 hours.

Results: External fixation was used in 45 patients(64%) and 37 patients were treated by angio. We found active arterial bleeding in 31 cases (44%). The combination of both treatment was used in 20 patients. Laparotomy was performed in 21 patients. Incidence of sistemic complications were high . Mortality was 26% . Mortality were higher in two groups: patients with TBI and those treated by laparotomy.

Conclusions: Arterial lesions demostrated by angio were high in our study(44%). In our experience a combined algorithm using both external fixation or angio based on type fracture control intrapelvic bleeding in most cases , although mortality in patients with pelvic fractre and haemodinamic instabilty remains high.

Exsanguination is the second most common cause of death in patients who suffer severe trauma. The management of haemodynamically unstable high-energy pelvic injuries remains controversial, as there are no universally accepted guidelines to direct surgeons on the ideal use of pelvic packing or early angio-embolisation. Additionally, the optimal resuscitation strategy, which prevents or halts the progression of the trauma-induced coagulopathy, remains unknown. Although early and aggressive use of blood products in these patients appears to improve survival, over-enthusiastic resuscitative measures may not be the safest strategy.

This paper provides an overview of the classification of pelvic injuries and the current evidence on best-practice management of high-energy pelvic fractures, including resuscitation, transfusion of blood components, monitoring of coagulopathy, and procedural interventions including pre-peritoneal pelvic packing, external fixation and angiographic embolisation.

Aims. This study aimed to analyze the correlation between transverse process (TP) fractures of the fourth (L4) and fifth (L5) lumbar vertebrae and biomechanical and haemodynamic stability in patients with a pelvic ring injury, since previous data are inconsistent. Patients and Methods. The study is a retrospective matched-pair analysis of patients with a pelvic fracture according to the modified Tile AO Müller and the Young and Burgess classification who presented to a level 1 trauma centre between January 2005 and December 2014. Results. A total of 728 patients with pelvic ring injuries were included, of whom 183 (25.1%) had a biomechanically unstable pelvic fracture. Of these patients, 84 (45.9%) had a fracture of a TP of L4 and/or L5. A total of 73 patients (13.4%) with a stable pelvic ring injury (p < 0.001) had a fracture of a TP. Patients with a fracture of a TP of L4 and/or L5 had a 5.5-fold risk (odds ratio (OR)) of having a biomechanically unstable pelvic injury. TP fractures (OR 1.6, p = 0.2) could not be confirmed as an independent predictor of haemodynamic instability. Conclusion. This is the first study that has demonstrated a positive correlation between a TP fracture of L4 and/or L5 and a biomechanically unstable pelvic ring injury. The presence of transverse process fractures of L4 and/or L5 indicates increased severity of pelvic injury and therefore can help in the planning of emergency treatment.

Introduction and Objectives: High-energy fractures of the pelvis carry a high mortality and pose a diagnostic and therapeutic challenge in modern orthopaedic trauma. A multidisciplinary approach has reduced mortality in the past two decades. In cooperation with the polytrauma ICU, we have developed a diagnostic-therapeutic algorithm to determine indications for laparotomy, external fixation, and angiography, in terms of clinical evolution and fracture type. Materials and Methods: This is a retrospective study of 67 patients with pelvic fractures and persistent hae-modynamic instability who were treated in our centre between 1994 and 2002. The following parameters were analyzed: personal data, AIS, ISS, RTS, type of fracture (Young and Burgess classification), associated injuries, haematologic requirements, and degree of adherence to the algorithm in terms of diagnostic and therapeutic measures. The following results variables were examined: mortality, incidence of systemic complications associated with traumatic illness (MOF, ARDS, DIC), and length of hospital stay. Results: The study involved a total of 67 patients, all with pelvic fractures and persistent haemodynamic instability. Average age was 37.7 years, and average time in the ICU was 13.8 days. In 53.7% of cases, patients were transported to the centre by ambulance, 41.8% by helicopter, and the remaining 4.5% by other means. Adjusted mortality was 25%. External fixation was used on 42 patients (62%) and angiography in 36 (53%). Both techniques were used in combination in 17 patients. Of the 36 patients who underwent angiography, 33 showed positive findings (91.7%). Exploratory laparotomy was required in 23 patients due to positive findings on abdominal ultrasound, which yielded positive results in 20 cases. Mortality in these patients was 45%. Average ISS was 29. Discussion and Conclusions: Rapid evaluation and a multidisciplinary approach are necessary in handling patients with pelvic fracture and haemodynamic instability. External fixation is a rapid procedure that is safe and simple, permitting the control of haemody-namic instability, which should be considered more as an emergency stabilisation technique than a reconstructive procedure. Abdominal ultrasound is a very sensitive method when deciding whether or not to perform an exploratory laparotomy. In cases with rotational instability of the pelvis, laparatomy should be done only after pelvic fixation. A diagnostic-therapeutic algorithm has been designed for the management of pelvic instability, with particular emphasis on indicators of a poor prognosis

The aim of this study was first, to determine whether CT scans undertaken to identify serious injury to the viscera were of use in detecting clinically unrecognised fractures of the thoracolumbar vertebrae, and second, to identify patients at risk of ‘missed injury’. . We retrospectively analysed CT scans of the chest and abdomen performed for blunt injury to the torso in 303 patients. These proved to be positive for thoracic and intra-abdominal injuries in only 2% and 1.3% of cases, respectively. However, 51 (16.8%) showed a fracture of the thoracolumbar vertebrae and these constituted our subset for study. There were eight women and 43 men with mean age of 45.2 years (15 to 94). There were 29 (57%) stable and 22 (43%) unstable fractures. Only 17 fractures (33.3%) had been anticipated after clinical examination. Of the 22 unstable fractures, 11 (50%) were anticipated. Thus, within the whole group of 303 patients, an unstable spinal injury was missed in 11 patients (3.6%); no harm resulted as they were all protected until the spine had been cleared. A subset analysis revealed that patients with a high Injury Severity Score, a low Glasgow Coma Scale and haemodynamic instability were most likely to have a significant fracture in the absence of positive clinical findings. This is the group at greatest risk. Clinical examination alone cannot detect significant fractures of the thoracolumbar spine. It should be combined with CT imaging to reduce the risk of missed injury

The management of spinal deformity in children with univentricular cardiac pathology poses significant challenges to the surgical and anaesthetic teams. To date, only posterior instrumented fusion techniques have been used in these children and these are associated with a high rate of complications. We reviewed our experience of both growing rod instrumentation and posterior instrumented fusion in children with a univentricular circulation. Six children underwent spinal corrective surgery, two with cavopulmonary shunts and four following completion of a Fontan procedure. Three underwent growing rod instrumentation, two had a posterior fusion and one had spinal growth arrest. There were no complications following surgery, and the children undergoing growing rod instrumentation were successfully lengthened. We noted a trend for greater blood loss and haemodynamic instability in those whose surgery was undertaken following completion of a Fontan procedure. At a median follow-up of 87.6 months (interquartile range (IQR) 62.9 to 96.5) the median correction of deformity was 24.2% (64.5° (IQR 46° to 80°) vs 50.5° (IQR 36° to 63°)). We believe that early surgical intervention with growing rod instrumentation systems allows staged correction of the spinal deformity and reduces the haemodynamic insult to these physiologically compromised children. Due to the haemodynamic changes that occur with the completed Fontan circulation, the initial scoliosis surgery should ideally be undertaken when in the cavopulmonary shunt stage.

Reviewing our experience of scoliosis in children with a Cavopulmonary Shunt or Fontan circulation and the cardiovascular challenges that this presents. A notes and x ray review was performed. Special attention was paid to the changes in cardiovascular status whilst prone. The review was from first presentation to latest follow up. There were 6 patients who underwent 7 major procedures between 2001 and 2009. All had cardiac procedures in early life. Both definitive fusion and growing instrumentation was used. All procedures were successful. Growing instrumentation allowed earlier primary surgery before completion of the Fontan circulation. All have been subsequently lengthened in a lateral position. The mean follow up is 56 months. There was one death 40 months following last surgery, cause unrelated to spinal surgery. In the older patients with a completed Fontan significant blood loss was seen, due to the raised venous pressure required to run the Fontan, and occult hypotension seen as a climbing difference between Pulmonary Artery Wedge Pressure and Central Venous Pressure were common when prone. We recommend early intervention, using instrumentation without fusion to correct the deformity over time and allow intervention prior to completing the Fontan circulation. As haemodynamic instability increases with increasing time in the prone position, surgery should be expedited rapidly

Purpose: To ascertain whether the methods of prone positioning we use have any influence on the incidence of perioperative critical incidents and development of postoperative liver dysfunction in our scoliosis patients. Methods: A retrospective review of 72 patients undergoing posterior correction and fusion for scoliosis from August 2006 to November 2007. Details were recorded from anaesthetic charts, operation notes, blood results and cell salvage data. Results: Patients ranged in age from 2 to 24 years. The methods of prone positioning were Transverse Bolsters (23), Allen Frame 4-point support (25), Lateral Bolsters (11) and the Knight Table (13). Perioperative haemodynamic instability was noted in 8% of patients on the Allen Frame, 43% on transverse bolsters, 15% on the Knight Table and 55% on lateral bolsters. Two cardiac arrests, one fatal and one with good recovery, both occurred on transverse bolsters. Of 22 other complications attributable to mechanical effects of prone positioning, 16 occurred on transverse bolsters, 4 on the Allen Frame, 1 on lateral bolsters and 1 on the Knight Table. 34% of patients had liver dysfunction postoperatively. None had been positioned on the Knight Table or lateral bolsters. There was no significant difference between the incidence of liver dysfunction associated with the Allen Frame or transverse bolsters. Conclusion: Transverse bolsters are associated with a high number of critical incidents and should be avoided if possible. Ethics approval – not required. Interest Statement - none

Traumatic disruption of the pelvic ring has a high risk of mortality. These injuries are predominantly due to high-energy, blunt trauma and severe associated injuries are prevalent, increasing management complexity. This population-based study investigated predictors of mortality following severe pelvic ring fractures managed in an organised trauma system. Cases aged greater than 15 years from 1st July 2001 to 30th June 2008 were extracted from the population-based state-wide Victorian State Trauma Registry for analysis. Patient demographic, pre-hospital and admission characteristics were considered as potential predictors of mortality. Multivariate logistic regression was used to identify predictors of mortality with adjusted odds ratios (AOR) and 95% confidence intervals (CI) calculated. There were 348 cases over the 8-year period. The mortality rate was 19%. Patients aged greater than 65 years were at higher odds of mortality (AOR 7.6, 95% CI: 2.8, 20.4) than patients aged 15–34 years. Patients hypotensive at the scene (AOR 5.5, 95% CI: 2.3, 13.2), and on arrival at the definitive hospital of care (AOR 3.7, 955 CI: 1.7, 8.0), were more likely to die than patients without hypotension. The presence of a severe chest injury was associated with an increased odds of mortality (AOR 2.8, 95% CI: 1.3, 6.1), while patients injured in intentional events were also more likely to die than patients involved in unintentional events (AOR 4.9, 95% CI: 1.6, 15.6). There was no association between the hospital of definitive management and mortality after adjustment for other variables, despite differences in the protocols for managing these patients at the major trauma services (Level 1 trauma centres). The findings highlight the importance of the need for effective control of haemodynamic instability for reducing the risk of mortality. As most patients survive these injuries, further research should focus on long term morbidity and the impact of different treatment approaches

Introduction. Following National patient safety alert on cement use in hip fracture surgery, we investigated the incidence and pattern of 72 hours peri-operative mortality after hip fracture surgery in a District General Hospital. Methods. We reviewed all patients who had hip fracture surgery between 2005-April, 2010. We recorded demographic variables, type of fracture, implant used, medical co-morbidity, seniority of operating surgeon and anaesthetist, peri-operative haemodynamic status, time and cause of death. Results. Over a 64 month period 15 cases were identified. Peri-operative death (PAD) was 1% (15/1402). 4/15 patients died intra-operatively. PAD was highest following Exeter Trauma Stem (ETS) implantation (5/85, 6%) and nil following Bipolar arthroplasty, Austin-Moore arthroplasty (AMA) or Cannulated screw fixation. PAD following total hip arthroplasty was 4% (1/25), Thompson's hemi-arthroplasty 2% (3/191), and Dynamic Hip Screw fixation 1% (6/695). Overall mortality after cemented implant was 2%. ETS implantation led to significantly increased peri-operative mortality compared to AMA (p=0.004). Operations were performed by both trainees (12) and Consultants (3). Both trainees (9) and Consultants (6) anaesthetised the patients. None of the patients belonged to ASA I or II (ASA III 6 and IV 9). All patients had significant cardio-vascular or pulmonary co-morbidity (Ca Lung 2, pulmonary fibrosis 1, end stage COAD 1, AF 6). Cemented implant insertion was followed by immediate haemodynamic collapse and death in 4/15, intra-operative haemodynamic instability in 1/15 and peri-operative instability in 5/15. Post-mortem was performed in 5/15: 2/5 were Pulmonary Embolism (PE), 2/5 bronchopneumonia and 1/5 Myocardial infarction (MI). 4/15 had suspected MI and 1/15 suspected PE. Conclusion. There was 1% risk of peri-operative death after hip fracture surgery. This risk was increased following cemented hemiarthroplasty and highest after ETS implantation. Risk was exacerbated in patients with pre-existing cardiovascular morbidity and independent of the seniority of the surgeon or the anaesthetist

Aims: To evaluate need for fast and correct diagnosis of pelvic fracture. Correlation of plain (AP) pelvic X-ray and and mortality and resultant necessity of emergency pelvic external þxation. Methods: We performed retrospective analysis of 152 patients with mechanically unstable pelvic fractures treated in period of 1996–2000. Observed pelvic ring fractures were type B1, B2 or C (and its subcroups) according to classiþcation of Tile, modiþed by Kellam and Browner. All of them (152) had at least two body regions injurie and ISS> 17 (mean ISS=29.2). 79 (52%) patients were haemodynamically unstable at admission. Parameters examined were as follows: injury severity, fracture type, hemodynamics at admission, time to and device of þxation, mortality. Results: Signiþcant differece was found in mortality in different fracture types: B1 11.1%, B2 Ð 5.6%, C Ð 37.5%. Also, a marked difference was seen in haemodynamic instability in different fracture types: B1- 55,5%, B2 Ð 20%, C Ð 73,6%. Mean injury severity scores: B1 -30,6 B2 -30,0 C Ð32,0. The need for emergency pelvic þxation was B1 Ð 44%, B2 Ð 5,6%, C Ð 42,4%, mostly AO tubular Ex. Fix was used. The study showed obvious correlation between the type of pelvic fracture and mortality. Conclusion: In pelvic fractures correct and fast diagnosis should be made in emergency room by plain AP x-ray. We found Tile pelvic fracture classiþcation to correlate patients haemodynamical state and guide fracture management and to be important prognostic criteria. Pelvic fracture which leads to increase of pelvic volume (B1, C) is prognostically worse and has higher mortality

Aims

Historically, patients undergoing surgery for adolescent idiopathic scoliosis (AIS) have been nursed postoperatively in a critical care (CC) setting because of the challenges posed by prone positioning, extensive exposures, prolonged operating times, significant blood loss, major intraoperative fluid shifts, cardiopulmonary complications, and difficulty in postoperative pain management. The primary aim of this paper was to determine whether a scoring system, which uses Cobb angle, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and number of levels to be fused, is a valid method of predicting the need for postoperative critical care in AIS patients who are to undergo scoliosis correction with posterior spinal fusion (PSF).

Aims

Clinical management of open fractures is challenging and frequently requires complex reconstruction procedures. The Gustilo-Anderson classification lacks uniform interpretation, has poor interobserver reliability, and fails to account for injuries to musculotendinous units and bone. The Ganga Hospital Open Injury Severity Score (GHOISS) was designed to address these concerns. The major aim of this review was to ascertain the evidence available on accuracy of the GHOISS in predicting successful limb salvage in patients with mangled limbs.

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.

Crescent fracture dislocations are a well-recognised subset of pelvic ring injuries which result from a lateral compression force. They are characterised by disruption of the sacroiliac joint and extend proximally as a fracture of the posterior iliac wing. We describe a classification with three distinct types. Type I is characterised by a large crescent fragment and the dislocation comprises no more than one-third of the sacroiliac joint, which is typically inferior. Type II fractures are associated with an intermediate-size crescent fragment and the dislocation comprises between one- and two-thirds of the joint. Type III fractures are associated with a small crescent fragment where the dislocation comprises most, but not all of the joint. The principal goals of surgical intervention are the accurate and stable reduction of the sacroiliac joint. This classification proves useful in the selection of both the surgical approach and the reduction technique. A total of 16 patients were managed according to this classification and achieved good functional results approximately two years from the time of the index injury. Confounding factors compromise the summary short-form-36 and musculoskeletal functional assessment instrument scores, which is a well-recognised phenomenon when reporting the outcome of high-energy trauma.

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.

We summarise and highlight the safety concerns within the field of trauma and orthopaedic surgery with particular emphasis placed on current controversies and reforms within the United Kingdom National Health Service.

Rupture of an aneurysm of the common iliac artery is a rare cause of pain in the hip. We describe an elderly hypertensive patient with an aneurysmal rupture of the left common iliac artery who presented with unilateral hip pain masquerading as septic arthritis.
