Aims. The best method of treating unstable pelvic fractures that involve the obturator ring is still a matter for debate. This study compared three methods of treatment: nonoperative, isolated posterior fixation and combined anteroposterior stabilization. Patients and Methods. The study used data from the German Pelvic Trauma Registry and compared patients undergoing conservative management (n = 2394), surgical treatment (n = 1345) and transpubic surgery, including posterior stabilization (n = 730) with isolated posterior osteosynthesis (n = 405) in non-complex Type B and C fractures that only involved the obturator ring anteriorly. Calculated odds ratios were adjusted for potential confounders. Outcome criteria were intraoperative and general short-term complications, the incidence of nerve injuries, and mortality. Results. Operative stabilization reduced mortality by 36% (odds ratio (OR) 0.64, 95% confidence interval (CI) 0.42 to 0.98) but the incidence of complications was twice as high (OR 2.04, 95% CI 1.57 to 2.64). Mortality and the incidence of neurological deficits at discharge were no different after isolated posterior or combined anteroposterior fixation. However, the odds of both surgical (98%, OR 1.98, 95%CI 1.22 to 3.22) and general complications (43%, OR 1.43, 95% CI 1.02 to 2.00) were higher in the group with the more extensive surgery. Conclusion. Operative stabilization is recommended for non-complex unstable pelvic fractures. The need for anterior fixation of obturator ring fractures should, however, be considered critically.

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.

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.

In the management of a pelvic fracture prompt recognition of an unstable fracture pattern is important in reducing mortality and morbidity. It is believed that a fracture of the transverse process of L5 is a predictor of pelvic fracture instability. However, there is little evidence in the literature to support this view. The aim of this study was to determine whether a fracture of the transverse process of L5 is a reliable predictor of pelvic fracture instability. We reviewed our hospital trauma database and identified 80 patients who sustained a pelvic fracture between 2006 and 2010. There were 32 women and 48 men with a mean age of 40 years (10 to 96). Most patients were injured in a road traffic accident or as a result of a fall from a height. A total of 41 patients (51%) had associated injuries. The pelvic fractures were categorised according to the Burgess and Young classification. There were 45 stable and 35 unstable fractures. An associated fracture of the transverse process of L5 was present in 17 patients; 14 (40%) of whom had an unstable fracture pattern. The odds ratio for an unstable fracture of the pelvis in the presence of a fracture of the transverse process of L5 was 9.3 and the relative risk was 2.5. A fracture of the transverse process of L5 in the presence of a pelvic fracture is associated with an increased risk of instability of the pelvic fracture. Its presence should alert the attending staff to this possibility

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

The identification of high-risk factors in patients with fractures of the pelvis at the time of presentation would facilitate investigation and management. In a series of 174 consecutive patients with unstable fractures of the pelvic ring, clinical data were used to calculate the injury severity score (ISS), the triage-revised trauma score (T-RTS), and the Glasgow coma scale (GCS). The morphology of the fracture was classified according to the AO system and that of Burgess et al. The data were analysed using univariate and multivariate methods in order to determine which presenting features were identified with high risk.

Univariate analysis showed an association between mortality and an ISS over 25, a T-RTS below eight, age over 65 years, systolic blood pressure under 100 mmHg, a GCS of less than 8, blood transfusion of more than ten units in the first 24 hours and colloid infusion of more than six litres in the first 24 hours. Multivariate analysis showed that age, T-RTS and ISS were independent determinants of mortality. A T-RTS of eight or less identified the cohort of patients at greatest risk (65%). The morphology of the fracture was not predictive of mortality. We recommend the use of the T-RTS in the acute situation in order to identify patients at high risk.

A system for assessment of function after major pelvic injuries is proposed. This numerical system developed from a five-year prospective study of 60 patients. Five factors were assessed and scored: pain, standing, sitting, sexual intercourse and work performance. The total score then gave a clinical grade as excellent, good, fair or poor. The scoring system allows comparison between early and late results and also between various methods of treatment.

1. A case of fractured pelvis with massive haemorrhage from the right superior gluteal artery and thrombosis of the right ilio-femoral venous system is reported.

2. The treatment included ligature of the artery and extensive thrombectomy. Ten litres of blood were transfused.

Aims

The impact of concomitant injuries in patients with proximal femoral fractures has rarely been studied. To date, the few studies published have been mostly single-centre research focusing on the influence of upper limb fractures. A retrospective cohort analysis was, therefore, conducted to identify the impact and distribution of concomitant injuries in patients with proximal femoral fractures.

We describe the routine imaging practices of Level 1 trauma centres for patients with severe pelvic ring fractures, and the interobserver reliability of the classification systems of these fractures using plain radiographs and three-dimensional (3D) CT reconstructions. Clinical and imaging data for 187 adult patients (139 men and 48 women, mean age 43 years (15 to 101)) with a severe pelvic ring fracture managed at two Level 1 trauma centres between July 2007 and June 2010 were extracted. Three experienced orthopaedic surgeons classified the plain radiographs and 3D CT reconstruction images of 100 patients using the Tile/AO and Young–Burgess systems. Reliability was compared using kappa statistics. A total of 115 patients (62%) had plain radiographs as well as two-dimensional (2D) CT and 3D CT reconstructions, 52 patients (28%) had plain films only, 12 (6.4%) had 2D and 3D CT reconstructions images only, and eight patients (4.3%) had no available images. The plain radiograph was limited to an anteroposterior pelvic view. Patients without imaging, or only plain films, were more severely injured. A total of 72 patients (39%) were imaged with a pelvic binder in situ.

Interobserver reliability for the Tile/AO (Kappa 0.10 to 0.17) and Young–Burgess (Kappa 0.09 to 0.21) was low, and insufficient for clinical and research purposes.

Severe pelvic ring fractures are difficult to classify due to their complexity, the increasing use of early treatment such as with pelvic binders, and the absence of imaging altogether in important patient sub-groups, such as those who die early of their injuries.
