Purpose of study:. The presence of an L5 transverse process fracture is reported in many texts to be a marker of pelvis fracture instability. There is paucity of literature to support this view. Available studies have been performed on patients who were already known to have a pelvis fracture. No study has attempted to document the presence of this lesion in the absence of a pelvis fracture. Primary aim: To identify the correlation between the presence of a L5 transverse process fracture and an unstable pelvic ring injury. Secondary aim: To establish whether a L5 transverse process fracture can occur in the absence of a pelvis fracture. Methods:. We conducted a retrospective review of all CT scans performed in patients who presented to a Level 1 Trauma Unit for blunt abdomino-pelvic trauma between January 1, 2012 and August 28, 2013. A total of 203 patients met our inclusion criteria. Results:. Fifty four of these 203 patients (26%) sustained a pelvis fracture. Of these 54 patients 26 (48%) had an unstable fracture pattern according to the AO classification. Five of these 26 patients (19%) had an associated L5 transverse process fracture. Seven (12%) had an L5 transverse process fracture associated with a stable fracture pattern. Three patients (1.4%) had an isolated L5 transverse process fracture in the absence of a pelvis fracture. Conclusion:. This study confirms the association between the presence of a L5 transverse process fracture and an unstable pelvis fracture pattern. This injury is rarely seen in the absence of a pelvis fracture so its presence should alert the treating clinicians to the existence of a pelvis fracture

Severe military pelvic trauma has a high mortality rate with previous work identifying an association between pelvic fracture and traumatic amputation (TA) of the lower limb (LL). Research has also identified casualties with this combination of injuries as the potential ‘future unexpected survivors’, however, most casualties die early from exsanguination, often before medical interventions can be performed. Therefore targeting injury prevention or mitigation might be the route to increased survivorship. This study investigates this combination of injury and identifies targets for preventative techniques. A search of the JTTR from 2003 to 2014 identified all patients with TA and all pelvic fractures. Of 989 casualties with LL TAs, 19% had an associated pelvic fracture, and this was associated with a 56% mortality rate compared to 24% without. Both pubic symphysis and sacroiliac separation alike were associated positively with traumatic amputation (p < 0.01). The combination of pelvic instability and TA had a mortality rate of 52%. We hypothesise that pelvic fracture may share a mechanistic link with TA, meaning fracture may occur as a consequence of the force and direction of the TA, and it may be possible to direct mitigation strategies at this injury in order to improve survival rates

The management of pelvic fractures remains a challenging problem for orthopaedic surgeons. The prompt recognition of unstable fracture patterns is important in reducing mortality and morbidity. It is perceived wisdom that a fracture of the transverse process of L5 is a predictor of pelvic fracture instability. There is a paucity of evidence in the literature to support this belief. The aim of our study was to determine if a fracture of the transverse process of L5 was a predictor of pelvic fracture instability. The Hospital Trauma database was reviewed. Between 2006 and 2009, 65 pelvic fractures were identified. They were classified according to the Burgess and Young classification. There were 37 stable and 28 unstable fractures. 14 patients had an associated fracture of the transverse process of L5; 9 were associated with an unstable fracture pattern. The odds ratio was 3; the relative risk 1.7. A fracture of the transverse process of L5 is associated with an increased risk of pelvic fracture instability. Its presence should alert the attending physicians to the possibility of an unstable injury

Background. pelvic fractures in elderly patients often result in poor prognosis due to immobilization associated complications. Thus, the target of the treatment in this patient group is early mobilization in order to reduce the risk of these complications. We report outcomes of 4 cases of pelvic fracture in elderly patients, who were treated with percutaneous screw fixation. Material and method. We examined medical records and images of 4 elderly patients between January 2012 and May 2012 in our center. Mean age of the patients was 88.8 years old (range 86–92 years). The causes of injury were motor vehicle accident in 3 patients, and a fall in 1 patient. Fracture types were ao type a in 1 patient, type b in 2 patients and type c in 1 patient. Mean injury severity score was 25 (10–57). We assessed functional status after the follow-up period using majeed. s. grading score for pelvic fractures. Result. No major complication including sever infection and deep vein thrombosis was observed during the follow-up period. Minor complication observed was screw loosening in 1 case, and screw prominence in another. Functional outcome by majeed. s. score were excellent in 1 case, and fair in 3 cases. The mean period between the operation and the first ride on the wheel chair was 3.5 (2–6) days. Conclusion. Early mobilization significantly affects the prognosis in multiple trauma patients. Percutaneous screw fixation may improve the prognosis in elderly patients with pelvic fracture

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

Introduction: L5/S1 injuries can be associated with pelvic fracture but unfortunately they are often missed. Left untreated these patients may suffer disabling lower back pain. Our goal is to study the frequency of these injuries in pelvic fractures treated at this institution, thereupon to determine how many are missed and the outcome if this injury is treated conservatively. We will describe the radiological findings, anatomical features and possible surgical treatments. Materials and Methods: A retrospective analysis was undertaken of pelvic fractures treated at this institution from 2000 onward. Outcome scores were taken from the patient records. All CT scans and x-rays were scru-tinised for a Lumbosacral Junction Injury(LJI). Numbers missed were tallied against numbers diagnosed and treated. Patient outcome measures were compared using the Matta Hip Scores. It was noted whether low back or hip pain contributed to their symptoms most. Results: The incidence of lumbar sacral injuries associated with vertical shear pelvic fractures was 20%. Of these, 75% had not been identified as a specific lumbar-sacral injury. The remaining 25% which were identified and treated with fixation of the lumbar sacral junction had an excellent result. We have identified specific morphology patterns and propose a CT based grading system. Discussion: We suggest that a heightened level of awareness is needed for these important injuries in pelvic trauma as their occurrence changes the management. The incidence appears to be higher than that reported by Isler and suggest our CT based classification be used to grade these injuries

Introduction: Patients with complex pelvic fractures with uncontrollable haemorrhage have a very mortality from pelvic haemorrhage and associated injuries. Management remains controversial and includes an number of techniques including pelvic stabilisation, angiography and direct surgical control of haemorrhage. Packing the pelvic cavity is a technique used rarely in this situation but is popular to control haemorrhage from other sources in similar situations. We have reviewed our experience of pelvic packing for uncontrollable haemorrhage to assess the effectiveness of this technique. Materials & Methods: From a prospectively gathered database of 132 patients with significant pelvic fractures admitted between April 2002 and December 2005, 8 patients (5 males and 3 females) with an average age of 52.9 yrs were identified who underwent pelvic stabilisation and packing as an emergent life saving procedure for uncontrolled haemorrhage associated with pelvic fracture. Basic data including their presenting vital signs, pelvic fracture pattern and associated injuries were recorded. All were subject to pelvic stabilisation packing and their subsequent clinical course including their transfusion requirements and additional management was also assessed. Results: 6 out of these 8 patients died, 5 within the first 24 hrs after injury and one after 14 days from sepsis & MOF/MODS. The exact source of bleed could not be identified in any of these patients and was assumed to be venous and from large fractured bony surfaces. 4 patients had angiography and embolisation in addition and 2 of these survived. Conclusion: The mortality of haemodynamically unstable pelvic fractures remains high and all modalities of treatment should be used to control bleeding. Pelvic packing may form an important part in the armamentarium of haemostatic measures; its role, however, needs to be better defined by larger multi-centre studies. Although difficult to conclude, the pelvic packing may have been responsible for reducing the mortality in this subgroup from a 100% to 75%

Injuries to the lower urinary tract are well recognized following fractures to the pelvic ring. The overall incidence of pelvic fractures is similar in men and women. However associated urological injuries occur less frequently in women. There are very few reported cases of combined bladder and urethral injury or combined intra- and extraperitoneal bladder rupture in women. Only two cases have been reported describing communication of the hip joint and an extra peritoneal bladder rupture. To our knowledge we are the first to describe a pelvic ring injury complicated by combined intra and extra-peritoneal bladder rupture, urethral injury and direct intraperitoneal communication of the ruptured bladder with a central dislocation of the hip joint. The mechanism of bladder laceration was gross displacement of the quadrilateral plate and pubic rami following acetabular fracture. This bone was found at laparotomy to be lying within the bladder cavity

Introduction. Pelvic fractures are indicators of severe trauma and high energy absorption. They are associated with multiple local or distant concomitant injuries, which explain their high mortality and morbidity. The aim of this study is to investigate the late sequel of traumatic-pelvic-fractures (PFX) focusing on quality-of-life and sexual-function. Methods. From a database of prospectively documented data, patients who had suffered a PFX and had been treated operatively in our institution from January 2008–2009 were recruited. Exclusion criteria were patients less than one-year post-injury, pathological-fractures, patients < 18 or >65, and patients with co-morbidities linked to sexual dysfunction. Demographics, injury-mechanisms, fracture-patterns (Young-Burgess classification), injury-severity-score (AIS/05-ISS), urogenital injuries and clinical outcome were recorded and analysed. Health-related-quality-of-life was assessed using the (EuroQol-5D) and sexual-function using the international-index-of-erectile-function and the female-sexual-function-index. The minimum follow-up was 12 months (12–30). Results. Out of 85 patients that met the inclusion criteria, 67 patients (24 females) with a mean age of 44 years (19–65) consented to participate in this study. Their mean ISS was 25(9–58), while 5(7.4%) had isolated PFX. There was shown to be a significant decrease in quality-of-life (p< 0.0001) and sexual-function (p< 0.0001). The decrease was significant in all 5 EQ5D domains with mobility, usual activities, and pain as the most significantly affected (p< 0.0001). 50.7% (34) patients reported a significant (p< 0.0001) decrease in their post-injury sexual function score (55.5%males, 47.8%females). Linear-regression showed urinary tract injury to be an independent risk factor for sexual dysfunction (p< 0.0001), while a Mann-Whitney-U-test identified that the PFX severity (VS-AP3-LC3-CMI vs. LC1-LC2-AP1-AP2-ILBL) correlated to sexual dysfunction (p=0.0463). Conclusion. Both genders, irrespective of age-subgroups, suffering a PFX severe enough to undergo surgery, are at risk of a significant decrease of their quality-of-life and sexual-function. The presence of certain fracture types and urinary tract injuries can be used as predictors of late morbidity and early multidisciplinary management

Introduction: Displaced fractures of the pelvic ring represents challenge for the trauma surgeon. Patients: From January 1999 to December 2006, the treatment was given to 134 patients (81 males, 53 females, aged 18–73 years) with pelvic ring fracture and dislocation. According to the AO (1988) classification, B type were 95, C type were 39 in cases. Surgical technique: Closed reduction and retention of unstable pelvic injuries (type B and C injuries), in order to restore the form and function of the posterior pelvis by percutaneous iliosacral screw and when is necessary antegrad screw fixation of the anterior pelvic ring osteosynthesis, using conventional fluoroscopy. 134 patients with a posterior pelvic fracture or fracture dislocation underwent screw fixation with fluoroscopy with 8.0-mm, or 9.0 mm cannulated screws, placed in a transiliosacral position in the vertebral body of SI, and S II. Among these patient, 71 fixed with percutaneuos screw in the anterior pelvic ring fracture too. Results: The average operating time was 23 min, the average screening time 2,11 min. Iatrogenic nerve damage was not found. All fractures healed within 3 months. 17% of the patients had residual pain, which were permanent or intermittent. Partly the reason could be the SI arthrosis, as we can see in 13% of the patients, or the fracture healing caused foramen stricture. Unfortunately we have lost 11 patients. The Majeed functional scoring was applied. In conclusion we could say that 81% of our patients were in the excellent and good category. Conclusions: The technique of percutaneous cannulated screws internal fixtion for treating the posterior and anterior portion of the pelvis has the advantages of small trauma, less bleeding stiff fixtion, which is an ideal and minimally invasive technique

Objectives

Osteosynthesis of anterior pubic ramus fractures using one large-diameter screw can be challenging in terms of both surgical procedure and fixation stability. Small-fragment screws have the advantage of following the pelvic cortex and being more flexible.

The aim of the present study was to biomechanically compare retrograde intramedullary fixation of the superior pubic ramus using either one large- or two small-diameter screws.

Evidence that L5 transverse process fracture indicates pelvic instability is insufficient and controversial. Because of unstable pelvis fractures have high mortality rate, they require urgent treatment and good follow-up. The lumbar region is also affected by high-energy traumas in the pelvis region, which causes damage to the muscles and ligamentous structures that adhere to the lumbar transverse process. For this reason, L5 transverse process fracture is thought to be an indicator showing pelvic instability. However, our study shows that this is not like that. This study was carried out in order to investigate the effect of L5 transvers process fracture on pelvic instability and lack of sufficient data in the literature. Between 2017–2020, 86 Patient who were hospitalized and treated with a diagnosis of pelvic fracture were retrospectively studied in our clinic. Pelvic X-Ray and tomography was taken pre-op for all patient. Demographic features, pre-op and post-op hemoglobin counts, how many units of blood transfusion needed in total, fixation method, surgical intervention, presence of additional injury, mechanism of injury for all patient were analyzed and the patients were categorized by investigating L5 transvers process fracture in their tomography. Fractures of patients were classified according toTyle classification. The patients were divided into two main groups as who stabil and unstabil pelvic fractures and L5 transvers process fracture and without. On stabil pelvic fractures and unstabil pelvic fractures, in term of instability effects of L5 transvers process fractures and those without were investigated. Also, changes in preop and post op hemoglaobin counts were investigated in pelvis with and without L5 transvers process fractures. With these, in terms of blood transfusion need the patients were evaluated whether there was a difference between those with L5 transvers process fractures and who did not. Again, whether the blood transfusion was statistically different in stable and unstable pelvis fractures was among the parameters looked at. In statistical analysis, no correlation was found between pelvic instability and L5 transvers process fracture. (p=0,933) No statistically significant difference was found in the evalution of blood transfusion between those with and without L5 transvers process fractures. (P=0,409)When the same parameter was evaluated in terms of stability and instability of the pelvis, it was seen that stability did not significantly affect the need for blood transfusion. (P=0,989) Pre-op and post-op hemoglobin changes of the patients who with L5 transvers process fracture and without were also analized. İn the analysis performed, there was no significant difference in patients with and without L5 transvers process fractures on pre-op and post-op hemoglobin values. (p=0.771/p=0.118)However, Postoperative hemoglobin values were significanly lower in patient with L5 transvers process fracture compared to preopetative hemoglobin values. (p=0.001). L5 transvers process fracture is not a parameter to showing pelvic instability. Stabil and unstabil fractures did not change the need for blood transfusion. The literatüre still needs much more study on this topic

High energy pelvic injury poses a challenging setting for the treating surgeon. Often multiple injuries are associated, which makes the measurement of short- and long-term functional outcomes a difficult task. The purpose of this study was to determine the incidence of pelvic dysfunction and late impacts of high energy pelvic ring fractures on pelvic floor function in women, with respect to urinary, sexual and musculoskeletal function. This was compared to a similar cohort of women with lower limb fractures without pelvis involvement. The data in our study was prospectively gathered between 2010 and 2013 on 229 adult females who sustained injury between 1998 and 2012. Besides demographic and operative variables, the scores of three validated health assessment tools were tabulated: King's Health Questionnaire (KHQ), Female Sexual Function Index (FSFI) and the Short Musculoskeletal Functional Assessment (SMFA). A multivariate regression analysis was done to compare groups. The incidence of sexual dysfunction was 80.8% in the pelvis and 59.4% in the lower extremity group. A Wilcoxon rank sum test showed a significant difference in KHQ-score (p<0.01) with the pelvis group being worse. When adjusting for age, follow-up and Injury Severity Score this difference was not significant (p=0.28), as was for FSFI and SMFA score. The mean FSFI scores of both groups met the criteria for female sexual dysfunction (<26). Patients with a Tile C fracture have better FSFI scores (16.98) compared to Tile B fractures (10.12; p=0.02). Logistic regression predicting FSFI larger than 26.5 showed that older age and pelvic fractures have a higher likelihood having a form of sexual dysfunction. Sexual dysfunction after lower extremity trauma is found in patients regardless of pelvic ring involvement. Urinary function is more impaired after pelvic injuries, but more data is needed to confirm this. Older age and pelvic fracture are predictors for sexual dysfunction in women. This study is important as it could help counsel patients on the likelihood of sexual dysfunction, something that is probably under-reported and recognized during our patient follow up

Venous Thromboembolism (VTE) prophylaxis is an essential part of orthopaedic surgeries in preventing life-threatening thromboembolic events such as Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE). Orthopaedic surgery has the highest incidence rate of thromboembolic events as compared to any other surgical specialities, making it an essential component in managing any orthopaedic case. At Queen's Medical Centre (QMC), a major trauma centre in the United Kingdom (UK), sees up to 750 NOF fracture cases annually, making it one of the busiest trauma and orthopaedic centres in the UK. Our study aims to evaluate how VTE Prophylaxis is conducted in a UK Major Trauma Centre for NOF and pelvic fragility fractures and how human factors can improve its efficacy. The Nottingham University Hospitals (NUH) Trust has implemented new guidelines from August 2019 that patients with fragility fractures such as NOF and pelvic fractures are prescribed with 28 days VTE prophylaxis with Enoxaparin, or their own anti-coagulants if risk of thrombosis exceed the risk of bleeding. This is an adaptation from the trust to align their guidelines closer to the NICE 2018 guidelines. We will be evaluating the initial compliance of VTE Prophylaxis, identify and utilise human factors, then re-analyse the department after implementing interventions on the same batch of junior doctors working in the department. Data of 100 patients with fragility fractures were collected, 50 consecutive patients in the pre-intervention window during August 2019 and 50 in the post-intervention window during November 2019. The pre-intervention data had 43 NOF and 7 Pelvic fractures. Our study showed that 93% of NOF fracture and 100% of pelvic fracture received the correct course of VTE prophylaxis. The data was presented at the local department junior doctor academic session. Three simple human factor interventions were implemented over the course of September and October: Education to the trauma and orthopaedic department on the new guideline, extended VTE labels on drug charts for patients with fragility fractures, VTE reminder labels at doctors' stations. Another 50 consecutive patients' data were collected during November 2019. Data shows that 97.8% of NOF (p>0.05) and 60% of pelvic fracture (p>0.05) received the correct course of VTE prophylaxis. Our data has shown an increase in correct VTE prescription for NOF fracture patients, which is the main bulk of our fragility fracture patients whilst we see a drop in pelvic fracture patients. Due to the limited time frame of four months where junior doctors in the UK rotate between specialities, we are only able to collect data during the first month, implement interventions between datasets and collect data on the final month of the four-month rotation. A future bigger study might provide a more significant result on the department. We believe that the key to achieving 100% VTE prophylaxis in the T&O department is optimising human factors, educating junior doctors, who are not orthopaedic trained, with sufficient information of the guidelines, and evidence of the risk and benefits of providing prolonged VTE prophylaxis for orthopaedic patients. In conclusion, we found that QMC, a major trauma centre with high patient volume and turnover, has a high level of compliance with VTE prophylaxis for fragility fractures and it is imperative that utilising human factors will inch the department closer to its goal of 100% VTE compliance

Major orthopaedic fractures are an independent risk factor for the development of venous thromboembolism (VTE), which are significant causes of preventable morbidity and mortality in trauma patients. Despite thromboprophylaxis, patients who sustain a pelvic or acetabular fracture (PA) continue to have high rates of VTE (12% incidence). Thrombelastography (TEG) is a whole-blood, point-of-care test which provides an overview of the clotting process. Maximal amplitude (MA), from TEG analysis, is the measure of clot strength and values ≥65mm have been used to quantify hypercoagulability and increased VTE risk. Therefore, the primary aim was to use serial TEG analysis to quantify the duration of hypercoagulability, following surgically treated PA fractures. This is a single centre, prospective cohort study of adult patients 18 years or older with surgically treated PA fractures. Consecutive patients were enrolled from a Level I trauma centre and blood draws were taken over a 3-month follow-up period for serial TEG analysis. Hypercoagulability was defined as MA ≥65mm. Exclusion criteria: bleeding disorders, active malignancy, current therapeutic anticoagulation, burns (>20% of body surface) and currently, or expecting to become pregnant within study timeframe. Serial TEG analysis was performed using a TEG6s hemostasis analyzer (Haemonetics Corp.) upon admission, pre-operatively, on post-operative day (POD) 1, 3, 5, 7 (or until discharged from hospital, whichever comes sooner), then in follow-up at 2-, 4-, 6-weeks and 3-months post-operatively. Patients received standardized thromboprophylaxis with low molecular weight heparin for 28 days post-operatively. VTE was defined as symptomatic DVT or PE, or asymptomatic proximal DVT, and all participants underwent a screening post-operative lower extremity Doppler ultrasound on POD3. Descriptive statistics were used to determine the association between VTE events and MA values. For the primary outcome measure, the difference between the MA threshold value (≥65mm) and serial MA measures, were compared using one-sided t-tests (α=0.05). Twenty-eight patients (eight females, 29%) with a mean age of 48±18 years were included. Acetabular fractures were sustained by 13 patients (46%), pelvic fractures by 14 patients (50%), and one patient sustained both. On POD1, seven patients (25%) were hypercoagulable, with 21 patients (78%) being hypercoagulable by POD3, and 17 patients (85%) by POD5. The highest average MA values (71.7±3.9mm) occurred on POD7, where eight patients (89%) were hypercoagulable. At 2-weeks post-operatively, 16 patients (94%) were hypercoagulable, and at four weeks, when thromboprophylaxis was discontinued, six patients (40%) remained hypercoagulable. Hypercoagulability persisted for five patients (25%) at 6-weeks and for two patients (10%) by three months. There were six objectively diagnosed VTE events (21.4%), five were symptomatic, with a mean MA value of 69.3mm±4.3mm at the time of diagnosis. Of the VTE events, four occurred in participants with acetabular fractures (three male, 75%) and two in those with pelvic fractures (both males). At 4-weeks post-operatively, when thromboprophylaxis is discontinued, 40% of patients remained hypercoagulable and likely at increased risk for VTE. At 3-months post-operatively, 10% of the cohort continued to be hypercoagulable. Serial TEG analysis warrants further study to help predict VTE risk and to inform clinical recommendations following PA fractures

Introduction. The Tour de France, commonly recognised and the hardest physical endurance event on the planet, is an iconic cycling competition with a history of ever impressive performances and increasingly notable injuries. This study aims to methodologically catalogue and analyse injuries sustained by professional riders over a span of six years and understand the operative workload created by this prestigious race. (2018–2023). Methods. Data was gathered from multiple publicly available sources, including pro-cycling stats, news articles, team press releases and independent medical reports. Each injury was categorized by year, rider, and injury type. Results. From 2018–2023, there was a significant diversity in both injured body part and mechanism of injury. Of the 124 recorded race ending incidents clavicle fractures accounted 19.4%, laceration/contusions 12.1%, patella fractures 10.5% and elbow fractures 7.3%. Other. notable other body areas undergoing surgical intervention were hand fractures 5.6%, pelvic fractures 2.4% and femoral fracture 1.6%. At a mean of 20.67 injuries per tour, this accounts for almost exactly one race ending injury per day where an athlete finishes the day on the operating table, rather than the team bus. Discussion. The Tour de France's rigorous challenges are mirrored in its injury statistics. Over six years, clavicle fractures were most prevalent, likely due to cyclists' instinct to brace during crashes. Lacerations, contusions, and patella fractures also featured prominently. Alarmingly, each race stage averaged an injury severe enough for surgical intervention. This data highlights the imperative need for enhanced protective measures, race regulations, and medical preparedness to protect these elite athletes

Introduction and objectives. High-energy pelvic fractures are life-threatening injuries. Approximately 15% to 30% of patients with high-energy pelvic injuries are hemodynamic unstable, hemorrhagic shock remains the main cause of death in patients with pelvic fractures, with an overall mortality rate from 6% to 35%. The correlation between fracture pattern and mortality in polytrauma with pelvic fracture has been previously investigated. However, the purpose of our investigation was to evaluate the relationship of hemodynamic instability with the pelvic fracture pattern according to different classifications. Materials and Methods. A retrospective study of high-energy pelvic fractures was performed for consecutive patients admitted to the emergency Level I trauma center in the polytrauma unit of our institution from June 2007 to June 2010. A total of 759 patients polytrauma were attended, whom 100 had a pelvic fracture and were included in our study. Demographic data, mechanism of injury and associated injuries were recorded. The patients were classified as hemodynamic stable or unstable according to the ATLS protocol. The pelvic fracture patterns were divided into stable and unstable according to Young-Burgess and Tile classifications. Statistical analysis was performed to determine the relationship between fracture pattern and hemodynamic stability. Secondary outcomes were obtained: the relationship with TCE and pulmonary injury, usefulness of the external fixation, relationship between fracture pattern and embolization requests. Chi-square test was used for the analysis and OR test. Results. Male was the gender most frequent (70%), the average age was 45.2 years and the mortality rate was 24%, the main mechanism of injury was motor vehicle injury (41%). Pelvic fracture pattern (neither Tile classification nor Young-Burgess classification) showed no correlation with hemodynamic situation (p>0.05). Neither death could not be predicted on the basis of pelvic fracture pattern (p>0.05). We found statistical association between patients affected by pelvic fracture in polytrauma and head injury, and death (p<0.01). Conclusion. Pelvic fracture pattern is not useful to predict hemodynamic instability in polytrauma, regardless the classification system used. Pelvic fracture is not significantly associated with high risk of mortality; however it contributes to increase mortality risk in cases of head injury associated

Pelvic fractures in children are rare and potentially disastrous injuries. Using medical records and radiographs over a three year period from January 2008 to March 2011 at an academic hospital we retrospectively analysed the incidence, the associated data and management of these injuries. Results. During this time period 633 paediatric patients where admitted with trauma related injuries; only 19 had pelvic fractures, an incidence of 0.03%. The majority of these patients (13) were involved in PVA's; while MVA (3), fall from height (1) and sports injuries (1) made up the rest. Males (13) were injured more commonly and the average age of the patients was 9 years (3–14). There is debate of over the ideal paediatric pelvic fracture classification system in the literature. However, 13 pelvic fractures were classified stable; 3 were unstable fractures with disruption of the pelvic ring. In addition 2 iliac wing fractures and 1 avulsion (apophyseal) fracture were found. 58% of the patients had associated injuries, however, only 2 of the 19 had associated abdominal viscus injuries. Neither of these required exploratory laparotomy and were managed conservatively. The treatment of these pelvic fractures in our unit was patient specific and largely conservative. 17 patients' pelvic fractures were treated with bed rest, analgesia and mobilisation as pain allowed while the remaining 2 had pelvic external fixators. No ORIF's were performed. Associated orthopaedic injuries were managed accordingly. The average hospital stay of a patient with a pelvic fracture was 15 days (3–48 days). There were no mortalities during this time period

Introduction. Trauma is the leading cause of death and disability in children. Pelvic fractures although rare, with a reported incidence of one per 100,000 children per year are 2. nd. only to skull fractures with respect to morbidity. The objectives of this study were to improve understanding of paediatric pelvic fractures through a concise review of all aspects of these fractures and associated injuries. Understanding the patterns in which paediatric pelvic fractures and their associated injuries occur and the outcome of treatment is vital to the establishment of effective preventative, diagnostic and therapeutic interventions. Patients and Methods. All children admitted to our unit with a pelvic fracture over the 14-year period from January 1995 to December 2008 were identified. The complete medical records and radiographs of all patients were obtained and reviewed. Data recorded included, age, sex, mechanism of injury, Glasgow Coma Score, Injury Severity Score, fracture type, radiological investigation, length of in-patient stay, length of intensive care unit stay, blood transfusion requirement, associated injuries, management (both orthopaedic and non-orthopaedic), length of follow-up, and outcome. Results. Over the study period thirty-nine children with a pelvic fracture were treated at our institute. The patients ranged in age from 1 to 14 years with a mean age of 8.6. The mean Glasgow coma score at presentation was 13.25 (range 3-15). The mean Injury Severity Score (ISS) was 17.1 (range 4-75). The most common mechanism of injury was a pedestrian being struck by a motor vehicle. A pelvic fracture was evident on the initial plain radiographs of all 39 children. Further radiographic investigation (12 CT's and 1 MRI) of the pelvic injury were undertaken in 13 (33%) of the children. Additional posterior ring fractures were identified in 9. The majority of children (18/39, 46%) sustained a Torode and Zeig type 3 fracture. A total of 32 children (82%) sustained one or more associated injuries. Head injuries accounted for 25% of these. Associated orthopaedic/skeletal injuries consisted of 22 fractures in 18 children accounting for 33% of all associated injuries. Fourteen children required a total of 24 acute surgical procedures, these were divided into orthopadic (n=12) and non-orthopaedic (n=12). The orthopaedic management of the pelvic fracture was non-operative in 37 (94%) of the children. Mean out-pateint clinical follow-up was for 27 months (range 3-85). There was one mortality in this series. Eight children (20%) suffered long term sequale. Conclusion. Pediatric pelvic fractures differ from their adult counterpart in etiology, fracture type, and associated injury pattern. They represent a reliable marker for severe trauma and associated injuries should be sought out in all cases. Injury to other organ systems should prompt early evaluation by the appropriate specialists. Optimal treatment guidelines for paediatric pelvic fractures are not yet fully defined but would seem to favour the management of more skeletally mature adolescents by the same principles used in the adult population

The management of pelvic fractures remains a challenging problem for orthopaedic surgeons. The prompt recognition of unstable fracture patterns is important in reducing mortality and morbidity. It is perceived wisdom that a fracture of the transverse process of L5 is a predictor of pelvic fracture instability. There is a paucity of evidence in the literature to support this belief. The aim of our study was to determine if a fracture of the transverse process of L5 was a predictor of pelvic fracture instability. The Hospital Trauma database was reviewed. Between 2006 and 2009, 65 pelvic fractures were identified. They were classified according to the Burgess and Young classification. There were 37 stable and 28 unstable fractures. 14 patients had an associated fracture of the transverse process of L5; 9 were associated with an unstable fracture pattern. The odds ratio was 3; the relative risk 1.7. A fracture of the transverse process of L5 is associated with an increased risk of pelvic fracture instability. Its presence should alert the attending physicians to the possibility of an unstable injury
