J Orthop 2024; 57:60-64. [PMID: 38994439 PMCID: PMC11233788 DOI: 10.1016/j.jor.2024.06.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2024] [Accepted: 06/09/2024] [Indexed: 07/13/2024] Open
Abstract
Background Given the novelty of three-dimensional (3D) printing-assisted fracture surgery in orthopaedics, surgeon familiarity is limited and learning curve is high. As such, it is unclear how the introduction of 3D printing into clinical practice for pelvic and acetabular fracture surgery would impact perioperative outcomes. The aim of this study was to determine the impact of introducing 3D printing-assisted surgery on perioperative outcomes for traumatic pelvic and acetabular fractures. Methods We retrospectively identified consecutive patients who underwent surgical fixation of traumatic pelvic and acetabular fractures from 2018 to 2022 at a single tertiary hospital. The patients included in the study were divided into two groups: (1) 3D printing-assisted surgery and (2) conventional surgery. Baseline demographics and perioperative outcomes of total surgical duration, estimated blood loss, blood transfusion, number fluoroscopy images, fluoroscopy duration and postoperative disposition were recorded and compared between the two groups. Results In total, 26 patients were included in the present study, with 3D printing-assisted surgery being used in 34.6 % (n = 9) of cases. There were no significant differences in baseline demographics or fracture type between the 3D printing group and conventional group. As compared to patients who underwent conventional surgery, those that underwent 3D printing-assisted surgery had, on average, shorter surgical duration (299.8 ± 88.2 vs 309.1 ± 143.1 min), lesser estimated blood loss (706.3 ± 330.0 vs 800.0 ± 584.2 ml), lower transfusion rates (50.0 % vs 52.9 %), lower number of intraoperative fluoroscopy images (62.8 ± 74.5 vs 71.6 ± 47.9 images) and shorter fluoroscopy duration (235.0 ± 79.2 vs 242.3 ± 83.5 min), although statistical significance was not achieved. None of the patients in the present study developed surgical complications postoperatively. Conclusion The introduction of 3D printing-assisted surgery in clinical practice for pelvic and acetabular fractures is a safe and viable adjunct in pelvic and acetabular surgery, achieving comparable perioperative outcomes in the initial phase.

Prevalence of pelvic CT angiography (CTA) and angiographic embolization in geriatric patients with pelvic ring fractures presenting to two level I trauma centers. Injury 2024; 55:111767. [PMID: 39168011 DOI: 10.1016/j.injury.2024.111767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Revised: 06/13/2024] [Accepted: 08/01/2024] [Indexed: 08/23/2024]
Abstract
OBJECTIVES Hemorrhage in osteoporotic pelvic ring fractures is a rare, but serious complication. Most bleeding comes from the bone or venous plexuses, but arterial injury does occur. The purpose of this study was to characterize a large geriatric pelvic fracture cohort and determine the prevalence of pelvic CT angiography (CTA) and subsequent need for arterial embolization. METHODS A cohort of geriatric pelvic fracture patients at two level 1 trauma centers was reviewed. Many epidemiologic and patient factors were collected for cohort characterization. The primary outcome was if patients underwent a CTA of the pelvis and subsequently underwent arterial embolization. RESULTS There were 457 patients included and mean age was 83.1 years (range 65-100). Most patients had a low energy mechanism (91.4 %). In-hospital mortality was recorded for 30 cases (6.6 %). Of these deaths, two received a pelvic CTA and two had an embolization procedure. Pelvic CTA was performed on 33 patients (7.2 %). Fourteen patients (3.0 %) had an arterial embolization procedure. A high energy mechanism of injury was associated with receiving a pelvic CTA (p = 0.0067). Mechanism of injury was not associated with undergoing an embolization procedure (p = 0.685). DISCUSSION In the geriatric population, even patients with stable pelvic fractures can present with life-threatening arterial bleeding. A non-insignificant percentage of patients will require CTA for suspected bleeding (7.2 %) and embolization to treat confirmed arterial bleeding (3.0 %). CONCLUSIONS Bleeding events in geriatric pelvic ring injuries is a previously under researched area of orthopedic trauma. Further research is needed to elucidate the exact pathomechanisms of arterial injury and what patients or injury patterns are most significantly associated. Specifically, larger cohort sizes and evaluating our existing cohort with different injury classification systems may yield useful results.

Abstract
Pelvic ring fractures may present with relevant mechanical and haemodynamic instability. Classifications of the bony or ligamentous injuries of the pelvic ring are well established. The most common classifications used analyse the injury mechanisms and the resulting instability of the pelvic ring structure. Fracture classifications should be simple and easy to use, comprehensive, and radiographically and anatomically based, resulting in a hierarchical alphanumeric order of types and subtypes and thereby allow adequate treatment decisions based on a high degree of inter- and intraobserver reliability. In 2018 a new AO/OTA pelvic ring fracture and dislocation classification was published that combined the most commonly used "historical" classification schemes, e.g. the Tile/AO classification and the classification according to Young and Burgess. Compared with these older classifications, several relevant changes were integrated in the 2018 edition. The changes between the AO/OTA 1996/2007 and 2018 classifications were analysed in detail. Overall, several problems were identified regarding the type-B pelvic ring injury classification. These changes may result in difficulties in classifying pelvic ring injuries and thereby prevent relevant comparisons between former and future clinical studies on pelvic injuries.Level of Evidence: V.

Automated Association for Osteosynthesis Foundation and Orthopedic Trauma Association classification of pelvic fractures on pelvic radiographs using deep learning. Sci Rep 2024; 14:20548. [PMID: 39232189 PMCID: PMC11374898 DOI: 10.1038/s41598-024-71654-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Accepted: 08/29/2024] [Indexed: 09/06/2024] Open
Abstract
High-energy impacts, like vehicle crashes or falls, can lead to pelvic ring injuries. Rapid diagnosis and treatment are crucial due to the risks of severe bleeding and organ damage. Pelvic radiography promptly assesses fracture extent and location, but struggles to diagnose bleeding. The AO/OTA classification system grades pelvic instability, but its complexity limits its use in emergency settings. This study develops and evaluates a deep learning algorithm to classify pelvic fractures on radiographs per the AO/OTA system. Pelvic radiographs of 773 patients with pelvic fractures and 167 patients without pelvic fractures were retrospectively analyzed at a single center. Pelvic fractures were classified into types A, B, and C using medical records categorized by an orthopedic surgeon according to the AO/OTA classification system. Accuracy, Dice Similarity Coefficient (DSC), and F1 score were measured to evaluate the diagnostic performance of the deep learning algorithms. The segmentation model showed high performance with 0.98 accuracy and 0.96-0.97 DSC. The AO/OTA classification model demonstrated effective performance with a 0.47-0.80 F1 score and 0.69-0.88 accuracy. Additionally, the classification model had a macro average of 0.77-0.94. Performance evaluation of the models showed relatively favorable results, which can aid in early classification of pelvic fractures.

MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1375. [PMID: 39202655 PMCID: PMC11356669 DOI: 10.3390/medicina60081375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/31/2024] [Revised: 08/12/2024] [Accepted: 08/19/2024] [Indexed: 09/03/2024]
Abstract
Background and Objectives: Anterior sacroiliac fracture dislocation (ASFD), also known as locked pelvis, is a rarely reported diagnosis. The types of ASFDs are often misdiagnosed as lateral compression fractures due to the presence of crescent fractures. In this study, we distinguished ASFD from lateral compression fractures (LC 2) and studied their characteristics. Materials and Methods: This is a retrospective study involving patients from a Level 1 trauma center. Fifty-nine patients under the age of 65 years with crescent fractures caused by a high-energy mechanism were investigated. Results: The incidence of ASFD was 25% (15 of 59) in patients with crescent fractures. Among the 15 patients, 6 had override of the ilium over the sacrum, inhibiting reduction in the sacroiliac joint. Pre-operative radiographic evaluations revealed that vertical displacement of the ASFD was larger than that of lateral compression fracture (LC 2) in the outlet view (mean 9.5 vs. 1.9 mm, p = 0.013), and the pelvic asymmetry ratio was larger in ASFD (mean 7.8 vs. 4.1, p = 0.006) in the pelvis AP view. All patients achieved union after surgery. Post-operative radiography showed no significant vertical displacement difference. There was no difference in vascular injury or hemodynamic instability requiring embolization or preperitoneal pelvic packing (PPP) between the two groups. Conclusions: Patients with ASFD have greater vertical displacement and asymmetry compared to patients with LC 2 fractures. These fractures must be distinguished for appropriate reduction and anterior plate fixation.

Abstract
Purpose To compare anterior plate fixation (SP fixation) both alone and in combination with an additional posterior sacroiliac screw (SP+SIS fixation) as a treatment for pelvic ring injuries with widening of the pubic symphysis and disruption to the anterior sacroiliac ligaments. Methods To find studies with pelvic ring injuries (APC II; B2.3d) and SP or SP+SIS fixation, a systematic literature review was conducted by searching four databases. A protocol was published a priori at Open Science Framework (https://doi.org/10.17605/OSF.IO/3YHAV). Exclusion criteria included perineal injuries, chronic instability of the symphysis, complete sacroiliac separation, and pediatric patients (age <18 years). Primary outcomes of interest were defined as implant failure, health-related quality of life, and revision rate. Results Altogether, 1861 studies were screened, and 40 studies qualified for full-text analysis. In total, 14 studies (two surveys, six biomechanical studies, and six retrospective clinical studies) were included. The surveys revealed that surgeons who had more recently begun practicing were more likely to use posterior fixation (SP+ISS). The biomechanical studies were heterogenous and did not yield a uniform pattern. In clinical studies, 117 patients (45%) received SP fixation, and 142 patients (55%) received SP+SIS fixation. Complications occurred in 31 SP patients (30%) and in five SP+SIS patients (3.5%). Conclusion A high risk of bias was uncovered, and reporting was found to be incomplete. SP+SIS may have the potential to improve outcomes, but the evidence remains too inconclusive to draw reliable recommendations.

Abstract
INTRODUCTION Open book injuries are challenging injuries that oftentimes require surgical treatment. Currently, treatment is performed with symphyseal plating requiring extensive surgery and entirely limiting physiological movement of the symphyseal joint, frequently resulting in implant failure. Therefore, we investigated the biomechanical properties of a minimally invasive tape suture construct (modified SpeedBridge™) as an alternative stabilization technique for the treatment of open book injuries in human cadaver pelvic rings. MATERIALS AND METHODS The symphysis of 9 human cadaver pelvises was dissected and dilated to 3 cm creating an open book injury. Next, the two osteosynthesis methods (plating, modified SpeedBridge™) were applied. All specimens then underwent cyclic horizontal and vertical loading, simulating biomechanical forces while sitting, standing and walking. For statistical analysis, 3D dislocation (mm) was calculated. RESULTS Total displacement (mm) of the pubic symphysis displayed the following means and standard deviations: native group 1.34 ± 0.62 mm, open book group 3.01 ± 1.26 mm, tape group 1.94 ± 0.59 mm and plate group 1.37 ± 0.41 mm. Comparison between native and open book (p = 0.029), open book and plate (p = 0.004), open book and tape (p = 0.031), as well as tape and plate group (p = 0.002) showed significant differences. No significant differences were found when comparing the native and tape (p = 0.059), as well as the native and plate (p = 0.999) group. CONCLUSION While both osteosynthesis techniques sufficiently stabilized the injury, symphyseal plating displayed the highest rigidity. The modified SpeedBridge™ as a tape suture construct provided statistically sufficient biomechanical stability while maintaining symphyseal micro mobility, consequently allowing ligamental healing of the injured joint without iatrogenic arthrodesis.

Abstract
CASE A 25-year-old man sustained a stable lateral compression Type I (LC I) pelvic ring injury upon missing the landing of a downhill ski jump. He presented with painful voiding from a displaced bony fragment, partially impaling the bladder wall. With operative fixation of the fracture and urologic co-management, the patient had excellent outcomes at 1-year follow-up. CONCLUSION We describe a rare urologic injury in the setting of an LC I pelvic ring injury. In the setting of an otherwise stable pelvic ring injury, careful review of imaging, detailed clinical history, and physical examination remain critical to optimizing patient outcomes.

Abstract
Pelvic ring injuries occur in varying severity and in vastly different patient demographics. Knowledge regarding which of these injuries require surgical intervention and which can be managed nonsurgically continues to evolve. Previous studies have shown validated criteria for sacral fractures and the posterior ring, explored the role of examination under anesthesia, and other forms of dynamic imaging. Although there is substantial information available, a comprehensive synthesis of this information is lacking. This article provides a comprehensive review of radiographic markers suggestive of stability, discusses treatment strategies, and proposes a treatment algorithm that is easily understood and applicable to not only those with a trauma background but also the general orthopaedic surgeon who will see these injuries frequently while on call.

Abstract
PURPOSE Unstable pelvic ring injury can result in a life-threatening situation and lead to long-term disability. Established classification systems, recently emerged resuscitative and treatment options as well as techniques, have facilitated expansion in how these injuries can be studied and managed. This study aims to access practice variation in the management of unstable pelvic injuries around the globe. METHODS A standardized questionnaire including 15 questions was developed by experts from the SICOT trauma committee (Société Internationale de Chirurgie Orthopédique et de Traumatologie) and then distributed among members. The survey was conducted online for one month in 2022 with 358 trauma surgeons, encompassing responses from 80 countries (experience > 5 years = 79%). Topics in the questionnaire included surgical and interventional treatment strategies, classification, staging/reconstruction procedures, and preoperative imaging. Answer options for treatment strategies were ranked on a 4-point rating scale with following options: (1) always (A), (2) often (O), (3) seldom (S), and (4) never (N). Stratification was performed according to geographic regions (continents). RESULTS The Young and Burgess (52%) and Tile/AO (47%) classification systems were commonly used. Preoperative three-dimensional (3D) computed tomography (CT) scans were utilized by 93% of respondents. Rescue screws (RS), C-clamps (CC), angioembolization (AE), and pelvic packing (PP) were observed to be rarely implemented in practice (A + O: RS = 24%, CC = 25%, AE = 21%, PP = 25%). External fixation was the most common method temporized fixation (A + O = 71%). Percutaneous screw fixation was the most common definitive fixation technique (A + O = 57%). In contrast, 3D navigation techniques were rarely utilized (A + O = 15%). Most standards in treatment of unstable pelvic ring injuries are implemented equally across the globe. The greatest differences were observed in augmented techniques to bleeding control, such as angioembolization and REBOA, more commonly used in Europe (both), North America (both), and Oceania (only angioembolization). CONCLUSION The Young-Burgess and Tile/AO classifications are used approximately equally across the world. Initial non-invasive stabilization with binders and temporary external fixation are commonly utilized, while specific haemorrhage control techniques such as pelvic packing and angioembolization are rarely and REBOA almost never considered. The substantial regional differences' impact on outcomes needs to be further explored.

Abstract
INTRODUCTION Spinal epidural hematoma is a rare condition that most commonly occurs as a complication of spinal surgery. For patients with neurological deficits, surgical decompression can generally provide good outcome. CASE A 56-year-old, otherwise healthy, patient was admitted to the orthopedic emergency department with a pelvic ring fracture. Over the course of 4 days, a lumbar spinal epidural hematoma developed, with the patient complaining of pain radiating to the S1 dermatome and saddle paresthesia. The hematoma was surgically decompressed, and the patient had a complete recovery. DISCUSSION To our knowledge, this is the first report of a spinal epidural hematoma after pelvic ring fracture. The etiology of spinal epidural hematoma is diverse, but it is most frequently observed after spinal surgery. It has rarely been observed after lumbar spinal fractures, nearly exclusively in patients with ankylosing spondylitis. CONCLUSION Pelvic ring fracture might result in spinal epidural hematoma. The presence of neurological deficits after such fractures is an indication for lumbosacral MRI. Surgical decompression will generally resolve the neurological symptoms.

Abstract
PURPOSE To assess the reliability of sequential examination under anaesthesia (EUA) to determine pelvic instability and to evaluate radiological and functional outcomes in unstable lateral compression (LC) injuries. METHODS A prospective case series study was conducted from 2020 to 2022 at a university hospital on 43 cases with LC injuries that met the inclusion criteria. Sequential EUA was carried out in three steps. Posterior-only fixation or anterior-posterior fixation was done according to the algorithm. Each patient was followed up for at least 12 months, both radiologically and functionally. RESULTS Forty cases proved unstable and were fixed. None showed secondary displacement in the anterior-posterior fixation group. However, five cases (19.2%) of the posterior-only fixation group showed secondary displacement with a mean of 5.9 mm. Four cases of them had tetra-ramic injuries. There is a high tendency for secondary displacement at 14.5 mm or more preoperative displacement of the rami. Patients with secondary displacement showed comparable functional outcome scores to patients without secondary displacement. Posterior-only fixation showed shorter operative time, lesser radiological exposure, blood loss and iatrogenic nerve injury than anterior-posterior fixation. CONCLUSION EUA is a reliable method to determine pelvic instability and management plan for LC fractures with unilateral anterior ring injury. Anterior-posterior fixation is needed if there is a tetra-ramic fracture or initial anterior ring displacement of 14.5 mm or more, irrespective of EUA.

Abstract
PURPOSE Post-operative complications following fixation of pelvic fractures can lead to mortality and increased morbidity. Available literature regarding complications is heterogeneous and knowledge on risk factors is limited. This study aims to identify the most common post-operative complications and their possible risk factors following pelvic fracture surgery. METHODS A retrospective cohort study was performed in two level-1 trauma centers in the Netherlands between January 2015 and January 2021. Included patients were all adult patients (≥ 18 years) with an operatively treated pelvic fracture (pelvic ring and/or acetabular fractures). Post-operative complications included surgical site infections (SSI), material-related complications, neurological complications, malunion/non-union and performed reoperations. A forward stepwise multivariable logistic regression analysis was used to identify any risk factors associated with these complications. RESULTS Complications occurred in 55 (24%) of the 233 included patients. SSI's were most common, occurring in 34 (15%) patients. Duration of surgery (odds ratio 1.01 per minute, 95% confidence interval 1.00-1.01) and obesity (odds ratio 1.10 per BMI point, 95% confidence interval 1.29-7.52) were independent risk factors for development of SSI. Less common post-operative complications were material-related complications (8%) and neurological damage (5%). CONCLUSION Limiting operation time by using less invasive and less time-consuming surgical approaches may reduce the risk of SSI. More awareness and post-operative screening for early signs of SSI is mandatory, especially in obese patients. Future research should include large prospective patient cohorts to determine risk factors for other post-operative complications associated with pelvic fracture surgery.

Abstract
The purpose of this review is to examine the literature on combined pelvic ring and acetabular fractures. We hope to further define the classifications, severities (ISS & Mortality), healing, radiographic parameters, and functional outcomes of such injuries to report all potential recommendations based on findings. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and a systematic search on PubMed and Google Scholar was performed. Articles included were in the English Language or through English translation, between the years 1996 and 2022. Articles that had met the inclusion criteria were systematically assessed for the relevance of their content. Eleven articles were identified with a total of 985 patients. All eleven were retrospective case series and the presence of both an injury within the pelvic ring and another injury within the acetabulum, either ipsilateral or contralateral, was the indication of a combination injury. The overall mortality rate averaged over all studies was 7.9% and the Injury Severity Score (ISS) of 22.98. When considering the higher mortality rate seen in pelvic ring injuries compared to the isolated acetabulum, there appears to be survivability beyond reductive means as a reason for reducing and fixing the pelvic ring first. However, accurate reduction of the acetabulum has a greater weight in overall patient recovery compared to the reduction of the pelvic ring and thus surgical emphasis on the anatomic reduction of the acetabulum may be paramount. Despite this good to excellent outcomes can be achieved with careful preoperative planning and surgical execution in patients with fractures of the pelvic ring and acetabulum. Further research as well as uniform radiographic scoring system and outcomes scores should be required to better evaluate and treat these injuries.

Abstract
Traumatic pelvic injuries usually include high-energy crush injuries and are associated with significant morbidity and mortality. Mortality rates range from 6% to 15% and increase to 36%-54% in cases of fractures that result in increased pelvic volume. Therefore, retroperitoneal hemorrhage can spiral and progress to hemorrhagic shock. Pelvic hemorrhage most commonly occurs secondary to disrupted pelvic veins or fractured bones, and 10%-20% of cases involve arterial injuries. Owing to extensive bleeding and limitations of surgery for pelvic hemorrhage, interventional treatment is at the forefront of pelvic hemorrhage management. CT is an accurate indicator of active hemorrhage in patients with pelvic trauma that affects the diagnosis and management, including interventions. Identification of the site of hemorrhage is necessary for focused interventional treatment. The current trend toward a more conservative approach for treatment of pelvic trauma and advances in interventional radiology in the field of pelvic trauma may favor widespread use of interventional treatment for patients with pelvic injuries. In this review, we discuss therapeutic modalities available to the interventional radiologist and common angiographic treatment strategies and techniques.

Abstract
Pelvic ring injuries comprise a spectrum of bony, ligamentous and muscular injuries, described by several common classification systems. However, the majority of injuries lie in areas of intermediate severity, where complexity and variable nature make it extremely hard to define in detail. This fact and associated injuries make it extremely difficult to conduct randomised control trials, with purpose to direct treatment guidelines. Thus, special interest and expertise are required by pelvic trauma surgeons, while surgical indications and fixation methods rely on their experience, at least in part. Namely, a significant grey zone of indication exists. As fixation methods evolve, specifically percutaneous fixation using osseous fixation pathways, some injuries in which morbidity bound with surgical fixation was considered too high relative to its benefits, may be considered eligible for surgical treatment nowadays. Moreover, due to significant progress in the treatment of the acute polytrauma casualties, the survival rate increased over the years, emphasizing the effect of long-term morbidity and functional outcome of pelvic ring injuries. The purpose of this manuscript is to describe the equivocal areas of controversies, hence "the grey zone", and to provide the readership with up-to-date published data. We aimed to collect and detail clinical and radiological clues in the diagnosis of intermediate unstable anterior-posterior compression and lateral compression injuries, and for the selection of treatment methods and sequence. Recent publications have provided some insights into specific injury features that are correlated with increased chance of instability, pain and delay in ambulation. Specific focus is given to the utility of examination under anaesthesia in selected cases. Other publications surveyed the shared experience of pelvic trauma surgeons as for the classification, indication and treatment sequence of pelvic ring injuries. Although the data hasn't matured yet to a comprehensive treatment algorithm, it may serve clinicians well when making treatment decisions in the grey zone of pelvic ring injuries, and serve as a basis for future prospective studies.

Abstract
OBJECTIVES Early pelvic binder placement in the field stabilizes pelvic fractures and tamponades potential hemorrhage within the pelvis. Despite known risk factors for pelvic fracture, it remains challenging to quickly triage and correctly apply a pelvic binder. We aim to develop a prediction model that exclusively uses prehospital criteria to inform the decision to place a pelvic binder. METHODS The trauma registry was used to identify all trauma patients admitted to an urban Level I trauma center between January 2013 and December 2017. Variables collected included patient demographics, mechanism of injury, prehospital vital signs, and the presence of a pelvic fracture. Participants were randomly assigned to a training group (70%) or a validation group (30%). Univariate analyses were used to identify significant predictors for use in multivariate predictive models. RESULTS A total of 8,480 (65% male; median age 49; median ISS 9) and 3,676 (65% male; median age 48; median ISS 9) trauma patients were randomly assigned to the training and validation groups, respectively. Univariate analysis showed significant likelihood of pelvic fracture associated with female sex, hemodynamic instability (initial systolic blood pressure < 90 mmHg), blunt injury type, specific mechanisms of injury (motor vehicle collision, motorcycle collision, pedestrian struck by motor vehicle, crushing injury, and riding an animal), impact location, and position in vehicle. Multivariate models adjusting for blunt type injury, hemodynamic instability, impact location, and position in vehicle showed that presence of two or more of these risk factors is significantly associated with presence of pelvic fracture. CONCLUSION Establishing select prehospital criteria for the empiric application of pelvic binders for patients in the field with blunt injuries, hemodynamic instability, frontal or side motor vehicle collision impact, and non-front seat passenger may improve outcomes among patients with pelvic fractures.

Abstract
Introduction posterior urethral injuries can occur in polytrauma settings, and may contribute to morbidity post-trauma. The aim of this study is to determine the occurrence of pelvic fracture urethral injury (PFUI) in adult polytrauma patients who were successfully stabilized and to appraise the nature of associated injuries. Methods the medical records of stabilized polytrauma patients≥ 18 years of age from January 2010 to December 2019 were retrospectively reviewed focusing on those presenting with bony pelvis disruptions. Injuries were categorized using the injury severity scale (ISS) while bony pelvis disruptions were classed according to the Young-Burgess classification. Data on the demography of the patient, mechanism of injury, nature, and severity of injuries, class of pelvic fracture-disruption, and urethral integrity were collected and analyzed accordingly. Results of 111 patients with bony pelvis disruptions, 95 of them had adequate information and were included in our analysis. The mean age of participants was 37.3 ± 11.8 years and most of them were males (87.4%). Blunt pelvic trauma occurred in 96.8%. Lateral compression pelvic injuries were prevalent at 39.0%. In 54.7% of the patients, the injury severity score (ISS) was ≥ 27. At 25.3% and 24.2% respectively, the abdomen and the lower extremities most frequently sustained a grade ≥ 3 injuries (abbreviated injury scale (AIS) ≥3). At a rate of 2.1%, spinal cord injury was the least observed. In the 10 years, there were 6 PFUI among 83 stabilized polytraumatized men with mean ISS of 35.5 ± 8.3. The incidence rate of PFUI was 0.6 per 8.3 pelvic disruptions in men per year. Symphysis pubis disruption or fracture of the pubis or both was consistently seen in all PFUI. Higher ISS significantly relates to PFUI (p <0.001). The mechanism of bony pelvis disruption and the class of bony pelvis injury are determined by the severity and trajectory of the impact apparently relates to PFUI only through fracture-disruption of the pubic symphysis or the pubis. Conclusion about 7.2% of men presenting with traumatic disruption of the bony pelvis in polytrauma setting sustain PFUI. In polytrauma settings, PFUI should be suspected in cases of fracture-disruption of the pubis or symphysis pubis from any mechanism.

Abstract
PURPOSE Pelvic fractures are associated with high morbidity and often require surgical intervention. An Anterior Posterior Compression (APC) II injury consists of disruption at the pubic symphysis and anterior sacroiliac joint. Studies investigating specific ligamentous contributions would aid in development of novel fixation techniques. The objective of this study is to determine the level of pelvic destabilization from progressive soft tissue disruptions associated with APC II injuries. METHODS Six fresh-frozen cadaveric pelvises were dissected of soft tissues, preserving joint capsules and ligaments. Each pelvis was secured in a double-leg stance and joint motion was tracked with the specimens cyclically loaded to 60% body weight. Each specimen was measured in the intact state and again following stepwise destabilization to an APC II injury model (PS: sectioned pubic symphysis, IPS JOINT: PS + ipsilateral anterior sacroiliac, sacrotuberous, sacrospinous ligaments sectioned, IPS LIGS: IPS JOINT + ipsilateral interosseous ligaments sectioned, IPS JOINT+CONT ASI: IPS LIGS + contralateral anterior sacroiliac ligament disruption). RESULTS Compared to the intact state, there was a statistically significant increase in movement in the IPS JOINT (ipsilateral 177%, p<0.001; contralateral 46%, p<0.005) and IPS JOINT+CONT ASI (ipsilateral 184%, p<0.002; and contralateral 62%, p<0.002) states bilaterally. No significant change was demonstrated in the PS or IPS LIGS state. CONCLUSION Disruption of ipsilateral ligamentous structures destabilized both sacroiliac joints. The interosseous and posterior sacroiliac ligaments provide the majority of stability of the sacroiliac joint and will likely benefit most from surgical stabilization. LEVEL OF EVIDENCE mechanism-based reasoning.

INTRODUCTION Lateral compression type 1 (LC1) pelvic ring injuries represent a heterogeneous group of fractures with controversial surgical indications. Recently, multiple institutions have suggested the safety and reliability of an emergency department (ED) stress to evaluate for occult instability. The purpose of this study was to correlate ED stress examination of LC1 pelvis fractures against a validated fracture instability scoring system. METHODS This was a retrospective review of a consecutive series of 70 patients presenting with minimally displaced LC1 fractures at a level 1 academic trauma center. All patients were stressed in the ED radiology suite, and displacement was measured by comparing calibrated stress radiographs with static radiographs (>10 mm displacement defined positivity). ED stress results were compared with radiographic scores assigned according to the validated Beckmann scoring system (score <7: stable-nonsurgical recommendation; score 7 to 9: indeterminant recommendation; and score >9: unstable-surgical recommendation). RESULTS Thirteen patients had a positive ED stress examination, and 57 patients stressed negative. The mean displacement was significantly different between the three groups (Beckmann 5 to 6: 3.31 mm, SD = 2.4; Beckmann 7 to 9: 4.23 mm, SD = 3.2; Beckmann 10+: 12.1 mm, SD = 8.6; P < 0.001). Zero of 18 patients in the stable group stressed positive, and only 3 of 38 patients in the indeterminant group stressed positive (7.9%). Finally, 10 of 14 patients in the unstable group stressed positive (71.4%; P < 0.001). Sacral displacement (P = 0.001), superior ramus location (P < 0.02), and sacral columns (P < 0.001) significantly predicted ED stress positivity in multivariate analysis. CONCLUSIONS Comparison of a validated instability scoring system with ED stress examination of minimally displaced LC1 fractures in awake and hemodynamically stable patients showed excellent correlation. This suggests that the ED stress examination is a useful diagnostic adjunct. LC1 fracture characteristics should be analyzed to determine which pelvic fracture characteristics determine occult instability before stress examination. LEVEL OF EVIDENCE Level III diagnostic.

Kim MJ, Lee SH, Jang JY, Lee JG. Comparison of mortality among hemorrhage-control methods performed for hemodynamically unstable patients with traumatic pelvic fractures: A multi-center study. Asian J Surg 2023; 46:444-450. [PMID: 35667931 DOI: 10.1016/j.asjsur.2022.05.085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 05/10/2022] [Accepted: 05/19/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND /Objective: We aimed to analyze the effects of hemorrhage control methods on the mortality of patients with hemodynamic instability due to pelvic fracture and investigate independent mortality risk factors in these patients. METHODS Ninety-seven pelvic bone fracture patients with hemodynamic instability who visited the emergency departments of two university hospitals over 5 years were enrolled. These patients were categorized based on 28-day mortality (survival group) and acute hemorrhage mortality (non-survival group). Forty-seven patients (48.5%) underwent pelvic angiography; 45 (46.4%), pre-peritoneal pelvic packing; and 19 (19.6%), external fixation. RESULTS Differences in hemorrhage control methods did not significantly affect mortality. However, there was a significant difference in mortality between the groups with and without hemorrhage control methods. Multivariate logistic regression analysis revealed that patient age, trauma and injury severity score (probability of survival), and blood transfusion amount within 24 h were independent risk factors for 28-day mortality. Meanwhile, patient age, Glasgow coma scale (GCS) score, systolic blood pressure (SBP), and blood transfusion amount within 24 h were independent risk factors for mortality due to acute hemorrhage. CONCLUSION Rapid and appropriate application of hemorrhage control methods can reduce acute hemorrhage-related mortality in hemodynamically unstable patients with pelvic fractures. Moreover, none of the hemorrhage control methods were superior for the decreasing mortality rate in these patients.

Development and preclinical evaluation of a cable-clamp fixation device for a disrupted pubic symphysis. COMMUNICATIONS MEDICINE 2022; 2:164.

Abstract
BACKGROUND Traumatic separation of the pubic symphysis can destabilize the pelvis and require surgical fixation to reduce symphyseal gapping. The traditional approach involves open reduction and the implantation of a steel symphyseal plate (SP) on the pubic bone to hold the reposition. Despite its widespread use, SP-fixation is often associated with implant failure caused by screw loosening or breakage. METHODS To address the need for a more reliable surgical intervention, we developed and tested two titanium cable-clamp implants. The cable served as tensioning device while the clamp secured the cable to the bone. The first implant design included a steel cable anterior to the pubic symphysis to simplify its placement outside the pelvis, and the second design included a cable encircling the pubic symphysis to stabilize the anterior pelvic ring. Using highly reproducible synthetic bone models and a limited number of cadaver specimens, we performed a comprehensive biomechanical study of implant stability and evaluated surgical feasibility. RESULTS We were able to demonstrate that the cable-clamp implants provide stability equivalent to that of a traditional SP-fixation but without the same risks of implant failure. We also provide detailed ex vivo evaluations of the safety and feasibility of a trans-obturator surgical approach required for those kind of fixation. CONCLUSION We propose that the developed cable-clamp fixation devices may be of clinical value in treating pubic symphysis separation.

Abstract
BACKGROUND Type I lateral compression pelvic fractures (LC-I) have historically been treated conservatively. Inferior outcomes in a distinctive subset of these injuries have been reported, therefore their management has shifted towards surgery. Revisiting the historical series of LC-I allows us to determine whether non-operative management of these unstable patterns results in poorer outcomes. The objective was to evaluate the differences in the rehabilitation progress, fracture consolidation, and displacement in non-operatively treated LC-I fractures that would be considered unstable using today's Association of Osteosynthesis (AO) criteria. METHODS We conducted a retrospective review of conservatively treated LC-I injuries in a single-level I trauma center between June 2010 and June 2014. Patients were distributed in stable (group A) and unstable (group B) groups according to the 2018 AO classification. Time to walk independently (TWI), time to return to work (TRW), fracture consolidation, and displacement were analyzed. RESULTS 34 patients, mean age of 45.5 ±14.5 years, were included. Mean TWI in groups A and B were 71.2 ±31.9 and 105.9 ±50.9 days (p=0.027). Mean TRW was 106 ±51.3 and 157 ±84 days in groups A and B, respectively (p=0.038). A difference in mean TWI and TRW of 34.7 and 51.3 days between groups was observed. No significant differences in fracture consolidation or displacement were observed. CONCLUSION Unstable fractures presented significantly longer TWI and TRW. The revised AO classification contributes to the identification of fracture patterns that correlate with prolonged rehabilitation in which additional treatment strategies might be considered.

Abstract
PURPOSE Additional CT imaging for fragility fractures of the pelvis (FFP) has a high detection rate for concomitant posterior ring fractures (cPRFs). However, the clinical value of routine additional CT imaging is unknown. This study aimed to determine the additional clinical value of routine CT imaging by changes in treatment policy and to establish the predictive value of pain localized around the sacroiliac joint (SIJ) for cPRFs. METHODS A prospective cohort study was conducted in a single teaching hospital in the Netherlands between November 2019 and November 2020. Patients were included if they were ≥ 65 years and had a (suspected) FFP on the pelvic radiograph. All patients underwent additional CT imaging. Changes in treatment policies ((possible) surgery, restrictive weight-bearing, hospital admission and outpatient follow-up) after CT imaging were registered. RESULTS Fifty-one patients (44 female) were included with a mean age of 80.6 years. Routine CT imaging revealed an additional cPRF in 27 patients (53%). A change in treatment occurred in 29 patients (57%), of which 7 (12%) were managed either surgical or with restrictive weight-bearing. The presence of pain around the SIJ had a sensitivity of 89% and specificity of 61% for detecting a cPRF. CONCLUSION Routine additional CT imaging has few direct therapeutic consequences with regards to surgical management or restrictive weight-bearing. These findings may be altered when considering a lower threshold for surgical intervention. The presence of pain around the SIJ was highly predictive for a clinically relevant cPRF.

Abstract
OBJECTIVE To determine if preoperative administration of venous thromboembolism (VTE) chemoprophylaxis (PPx) before pelvic and acetabular fracture surgery affects estimated blood loss (EBL), perioperative change in hemoglobin (ΔHgb), or transfusion rates. DESIGN Retrospective cohort study. SETTING Level 1 trauma center, southeastern United States. PATIENTS/PARTICIPANTS All pelvic and acetabular surgeries performed between April 2014 and February 2020. MAIN OUTCOME MEASUREMENTS EBL, immediate and 24-hour postoperative ΔHgb, and intraoperative/postoperative transfusion. RESULTS In all, 267 surgeries were included: 97 prechange and 170 postchange. Median injury severity score was 17 before versus 14 after the change. One surgeon retired and two started during the study, producing differences in acetabular approaches. Median surgical duration was longer postchange. Cohorts were otherwise similar. No differences were observed in EBL, ΔHgb, or transfusion rates. Rates of VTE and surgical site complications were unchanged. No VTE-related deaths occurred. In the as-treated analysis (63 patients given low-molecular-weight heparin <12 hours preoperatively vs. 190 patients not given PPx), no differences were observed. CONCLUSIONS Administration of VTE PPx within 12 hours of pelvic and acetabular surgery had no effect on perioperative blood loss. This study is limited by changes in faculty, but it suggests that traumatologists need not advocate for holding VTE PPx before pelvic and acetabular trauma surgery.

Abstract
Pelvic fractures are an increasingly common injury seen in the older population and represent a significant burden of morbidity and mortality in this age group, as well as a large financial burden on the health service. It is well established that early fixation of femoral neck and acetabular fractures improves outcomes and increases the chances of patients returning close to their premorbid functional baseline. However, fixation of fragility fractures of the pelvis is less well established in current practice. There has been recent development of novel stabilisation techniques for unstable pelvic fractures, designed to tackle the difficulties associated with fixation in poor bone quality, along with medical trials of parathyroid hormone analogue treatment. However, it is still current practice to manage nearly all fragility fractures of the pelvis conservatively. In this article, we consider whether the development of surgical stabilisation techniques for pelvic fragility fractures may have the potential to improve the well-described morbidity and mortality associated with them.

Abstract
BACKGROUND Paralytic ileus is a temporary inhibition of gastrointestinal mobility in the absence of mechanical obstruction. Ileus has previously been observed in up to 40% of patients undergoing bowel surgery, leading to increased morbidity and length of stay. Pelvic and acetabular fractures are often caused by high energy trauma and are associated with a risk of visceral injury. Prior to this study, there were no reported figures for the incidence of ileus in patients presenting with pelvic and/or acetabular fractures. METHODS All patients over the age of 16 presenting to a major trauma centre throughout 2019 were included. Data collected included patient demographics, injury pattern, fracture management and presence of ileus. As in previous studies, patients were identified as having ileus if they failed to tolerate an oral diet and open their bowels for more than three days (GI-2). Analysis assessed risk factors for ileus as well as its effect on length of stay. RESULTS An incidence of ileus of 40.35% was observed in the 57 included patients. Across all patients, ileus was three times more common in patients with a diagnosis of diabetes mellitus (p= 0.56) and 2.5 times more common in the presence of an open pelvic/ acetabular fracture (p= 0.73). Length of stay was significantly longer in patients under 65 years identified as having ileus (p= 0.046). Gender, age, opiate use, fracture management and surgical approach were not identified as risk factors for ileus. CONCLUSION/ FINDINGS This is the first study to report the incidence of and risk factors for ileus following admission with pelvic and/or acetabular fractures. Due to the morbidity and cost associated with this condition, further research is required to assess the effect of interventions to reduce its incidence in this patient subgroup.

Abstract
INTRODUCTION This study aimed to investigate potential factors, including delay to surgical stabilisation, affecting mortality in older patients sustaining pelvic or acetabular (PA) fractures. MATERIALS AND METHODS A retrospective review of the Trauma Audit and Research Network (TARN) database was performed to identify older patients (aged 65 and over) sustaining PA fractures treated surgically in a UK Major Trauma Centre (MTC) between 2015 and 2019. Chi-squared and Fisher tests were used to compare 1-year mortality rates following operative intervention between patients treated within 72 h and after 72 h. Kaplan-Meier curves were used to visualise survival probability; significant predictors of survival were found using Cox proportional hazard models. RESULTS Of 564 older patients with PA fractures, 70 met the inclusion criteria. The mean age was 76.1 years. The overall 1-year mortality rate was 20%. When patients were grouped by time to surgery (fracture fixation within or greater than 72 h), there was no statistically significant difference in 1-year mortality. Patients whose surgery was delayed more than 72 h were more likely to have longer hospital stays (p = 0.002) or to have suffered from polytrauma (p = 0.025). Age, Charlson Co-morbidities Index (CCI) and pre-op mobility status were associated with statistically significant differences in overall mortality. The same factors were associated with a significantly increased hazard of death in the multivariate Cox proportional hazards model. Patient gender, mechanism of injury, Injury Severity Score (ISS) > 15 and head injury were not significant predictors of mortality. CONCLUSION Surgical intervention within 72 h of injury did not result in decreased mortality in older patients with PA fractures. The 1-year mortality rate between older PA fractures and hip fractures was comparable. Consideration should be given to a combined multidisciplinary approach between orthogeriatric and expert PA surgeons for these patients.

Abstract
AIM This paper evaluates computer tomographic morphology of partial ligamentous lesions of the sacroiliac joint. We hypothesised that in antero-posterior compression (APC) injuries the anterior superior portion of the sacroiliac joint (SIJ) should open up the most as suggested by the vector forces outlined in the Young and Burgess classification. METHODS All patients who underwent operative fixation of a ligamentous APC pelvic injury between July 2009 and December 2015 in a single Level-1 trauma centre were included. Patients were case matched (1:1) to controls without pelvic injury. SIJ width was measured by two independent reviewers at the anterior superior and anterior inferior part of the SIJ. Wilcoxon ranged test was applied for analysis. RESULTS 70 patients (35 cases, 35 controls) were evaluated. Median inferior and superior SI joint widths were 5.27 (IQR 3.68-7.80) and 4.05 (IQR 3.13-5.31) mm in cases versus 2.24 (IQR 1.83-2.50) and 2.44 (IQR 2.14-2.65) mm in controls, respectively. The difference between the inferior and superior SI width in cases was larger than in controls (p-value < 0.01, median of -0.22 mm in the control group versus 1.51 mm in the cases). CONCLUSION Our data suggests that the inferior part of the SIJ opens up after injury more, relative to its superior portion. The vector of the force involved in rotationally unstable pelvic injuries is unlikely to be antero-posterior if the force causes the SI joint to widen up inferiorly first. This should be considered in SIJ fixation and challenges the APC mechanism in pure ligamentous rotationally unstable pelvic ring injuries.

Abstract
INTRODUCTION Pelvic and acetabular fractures are significant injuries associated with high morbidity or mortality. Intravenous drug users (IVDU) represent a challenging group of patients, with an increased risk of complications and infection. To our knowledge there has not been any published literature concerning IVDU and this type of injuries. PATIENTS AND METHODS A group of 19 patients with a history of IVDU and who had sustained an injury were identified. RESULTS The mean age at injury was 36 years old; nine had a pelvic fracture and ten had an acetabular fracture. No complications were observed in the pelvic group. In the acetabular group, the infection risk was 50% and the risk of femoral head avascular necrosis was 33%. The mean follow up was 43.1 months from injury. CONCLUSION We advise emphasis in the high infection and avascular necrosis rates, when consenting the patient for an operation. Furthermore, non-operative treatment should be considered, where possible. LEVEL OF EVIDENCE Level III. Retrospective cohort study. Prognostic-investigating the effect of a patient characteristic on the outcome of the disease.

An Automated Deep Learning Method for Tile AO/OTA Pelvic Fracture Severity Grading from Trauma whole-Body CT. J Digit Imaging 2021; 34:53-65. [PMID: 33479859 PMCID: PMC7886919 DOI: 10.1007/s10278-020-00399-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 10/14/2020] [Accepted: 11/10/2020] [Indexed: 01/13/2023] Open
Abstract
Admission trauma whole-body CT is routinely employed as a first-line diagnostic tool for characterizing pelvic fracture severity. Tile AO/OTA grade based on the presence or absence of rotational and translational instability corresponds with need for interventions including massive transfusion and angioembolization. An automated method could be highly beneficial for point of care triage in this critical time-sensitive setting. A dataset of 373 trauma whole-body CTs collected from two busy level 1 trauma centers with consensus Tile AO/OTA grading by three trauma radiologists was used to train and test a triplanar parallel concatenated network incorporating orthogonal full-thickness multiplanar reformat (MPR) views as input with a ResNeXt-50 backbone. Input pelvic images were first derived using an automated registration and cropping technique. Performance of the network for classification of rotational and translational instability was compared with that of (1) an analogous triplanar architecture incorporating an LSTM RNN network, (2) a previously described 3D autoencoder-based method, and (3) grading by a fourth independent blinded radiologist with trauma expertise. Confusion matrix results were derived, anchored to peak Matthews correlation coefficient (MCC). Associations with clinical outcomes were determined using Fisher's exact test. The triplanar parallel concatenated method had the highest accuracies for discriminating translational and rotational instability (85% and 74%, respectively), with specificity, recall, and F1 score of 93.4%, 56.5%, and 0.63 for translational instability and 71.7%, 75.7%, and 0.77 for rotational instability. Accuracy of this method was equivalent to the single radiologist read for rotational instability (74.0% versus 76.7%, p = 0.40), but significantly higher for translational instability (85.0% versus 75.1, p = 0.0007). Mean inference time was < 0.1 s per test image. Translational instability determined with this method was associated with need for angioembolization and massive transfusion (p = 0.002-0.008). Saliency maps demonstrated that the network focused on the sacroiliac complex and pubic symphysis, in keeping with the AO/OTA grading paradigm. A multiview concatenated deep network leveraging 3D information from orthogonal thick-MPR images predicted rotationally and translationally unstable pelvic fractures with accuracy comparable to an independent reader with trauma radiology expertise. Model output demonstrated significant association with key clinical outcomes.

Comparison of pelvic C-clamp and pelvic binder for emergency stabilization and bleeding control in type-C pelvic ring fractures. Sci Rep 2021; 11:2338. [PMID: 33504874 PMCID: PMC7840902 DOI: 10.1038/s41598-021-81745-z] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2020] [Accepted: 12/30/2020] [Indexed: 01/17/2023] Open
Abstract
Severe bleeding is the major cause of death in unstable pelvic ring fractures. Therefore, a quick and efficient emergency stabilization and bleeding control is inevitable. C-clamp and pelvic binder are efficient tools for temporary bleeding control, especially from the posterior pelvic ring. Yet the C-clamp requires more user knowledge, training and equipment. However, whether this makes up for a more efficient bleeding control, is still under debate. Patients with a type-C pelvic ring fracture were identified from the German Pelvic Registry (GPR) and divided into three groups of 40 patients (1. no emergency stabilization, 2. pelvic binder, 3. C-clamp). The matching occurred according to the parameters age, gender, initial RR and initial HB. Complication-and mortality rates were compared especially regarding bleeding control. Regarding ISS and fracture dislocation there was no difference. The use of the C-clamp resulted in more complications, a higher mortality rate due to severe bleeding and more blood transfusions were admitted. Moreover the pelvic binder was established noticeably faster. However, the C-clamp was more often rated as effective. There is no evidence of advantage comparing the C-clamp to the pelvic binder, regarding bleeding control in type-C pelvic ring fractures. In fact, using the pelvic binder even showed better results, as the time until established bleeding control was significantly shorter. Therefore, the pelvic binder should be the first choice. The C-clamp should remain a measure for selected cases only, if an adequate bleeding control cannot be achieved by the pelvic binder.

Abstract
Pelvic fractures occur in up to 25% of all severely injured trauma patients and its mortality is markedly high despite advances in resuscitation and modernization of surgical techniques due to its inherent blood loss and associated extra-pelvic injuries. Pelvic ring volume increases significantly from fractures and/or ligament disruptions which precludes its inherent ability to self-tamponade resulting in accumulation of hemorrhage in the retroperitoneal space which inevitably leads to hemodynamic instability and the lethal diamond. Pelvic hemorrhage is mainly venous (80%) from the pre-sacral/pre-peritoneal plexus and the remaining 20% is of arterial origin (branches of the internal iliac artery). This reality can be altered via a sequential management approach that is tailored to the specific reality of the treating facility which involves a collaborative effort between orthopedic, trauma and intensive care surgeons. We propose two different management algorithms that specifically address the availability of qualified staff and existing infrastructure: one for the fully equipped trauma center and another for the very common limited resource center.

Abstract
PURPOSE Recent papers have shown the utility of deep learning in detecting hip fractures with pelvic radiographs, but there is a paucity of research utilizing deep learning to detect pelvic and acetabular fractures. Creating deep learning models also requires appropriately labeling x-ray positions and hardware presence. Our purpose is to train and test deep learning models to detect pelvic radiograph position, hardware presence, and pelvic and acetabular fractures in addition to hip fractures. MATERIAL AND METHODS Data was retrospectively acquired between 8/2009-6/2019. A subset of the data was split into 4 position labels and 2 hardware labels to create position labeling and hardware detecting models. The remaining data was parsed with these trained models, labeled based on 6 "separate" fracture patterns, and various fracture detecting models were created. A receiver operator characteristic (ROC) curve, area under the curve (AUC), and other output metrics were evaluated. RESULTS The position and hardware models performed well with AUC of 0.99-1.00. The AUC for proximal femoral fracture detection was as high as 0.95, which was in line with previously published research. Pelvic and acetabular fracture detection performance was as low as 0.70 for the posterior pelvis category and as high as 0.85 for the acetabular category with the "separate" fracture model. CONCLUSION We successfully created deep learning models that can detect pelvic imaging position, hardware presence, and pelvic and acetabular fractures with AUC loss of only 0.03 for proximal femoral fracture.

Pelvic injury prognosis is more closely related to vascular injury severity than anatomical fracture complexity: the WSES classification for pelvic trauma makes sense. World J Emerg Surg 2020; 15:48. [PMID: 32807185 PMCID: PMC7433075 DOI: 10.1186/s13017-020-00328-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 08/06/2020] [Indexed: 01/03/2023] Open
Abstract
Background The most common cause of death in cases of pelvic trauma is exsanguination caused by associated injuries, not the pelvic injury itself. For patients with relatively isolated pelvic trauma, the impact of vascular injury severity on outcome remains unclear. We hypothesized that the severity of the pelvic vascular injury plays a more decisive role in outcome than fracture pattern complexity. Methods Medical records of patients with pelvic fracture at a single center between January 2016 and December 2017 were retrospectively reviewed. Those with an abbreviated injury scale (AIS) score ≥ 3 in areas other than the pelvis were excluded. Lateral compression (LC) type 1 fractures and anteroposterior compression (APC) type 1 fractures according to the Young-Burgess classification and ischial fractures were defined as simple pelvic fractures, while other fracture types were considered complicated pelvic fractures. Based on CT, vascular injury severity was defined as minor (fracture with or without hematoma) or severe (hematoma with contrast pooling/extravasation). Patient demographics, clinical parameters, and outcome measures were compared between the groups. Results Severe vascular injuries occurred in 26 of the 155 patients and were associated with poorer hemodynamics, a higher injury severity score (ISS), more blood transfusions, and a longer ICU stay (3.81 vs. 0.86 days, p = 0.000) and total hospital stay (20.7 vs. 10.1 days, p = 0.002) compared with minor vascular injuries. By contrast, those with complicated pelvic fractures (LC II/III, APC II/III, vertical shear, and combined type fracture) required a similar number of transfusions and had a similar length of ICU stay as those with simple pelvic fractures (LC I, APC I, and ischium fracture) but had a longer total hospital stay (13.6 vs. 10.3 days, p = 0.034). These findings were similar even if only patients with ISS ≥ 16 were considered. Conclusions Our results indicate that even in patients with relatively isolated pelvic injuries, vascular injury severity is more closely correlated to the outcome than the type of anatomical fracture. Therefore, a more balanced classification of pelvic injury that takes both the fracture pattern and hemodynamic status into consideration, such as the WSES classification, seems to have better utility for clinical practice.

Abstract
Pelvic vascular injuries are typically caused by high-energy trauma. The majority of these injuries are caused by motor vehicle collisions, and the rest are caused by falls and industrial or crush injuries. Pelvic vascular injuries are frequently associated with pelvic ring disruption and have a high mortality rate due to shock as a result of pelvic bleeding. Morbidity and mortality resulting from pelvic vascular injury are due to pelvic hemorrhage and resultant exsanguination, which is potentially treatable and reversible if it is diagnosed early with multidetector CT and treated promptly. The pelvic bleeding source can be arterial, venous, or osseous, and differentiating an arterial (high-pressure) bleed from a venous-osseous (low-pressure) bleed is of paramount importance in stratification for treatment. Low-pressure venous and osseous bleeds are initially treated with a pelvic binder or external fixation, while high-pressure arterial bleeds require angioembolization or surgical pelvic packing. Definitive treatment of the pelvic ring disruption includes open or closed reduction and internal fixation. Multidetector CT is important in the trauma setting to assess and characterize pelvic vascular injuries with multiphasic acquisition in the arterial and venous phases, which allows differentiation of the common vascular injury patterns. This article reviews the anatomy of the pelvic vessels and the pelvic vascular territory; discusses the multidetector CT protocols used in diagnosis and characterization of pelvic vascular injury; and describes the spectrum of pelvic vascular injuries, the differentiation of common injury patterns, mimics, and imaging pitfalls.

Abstract
BACKGROUND Anterior plating is the treatment of choice in anterior pelvic ring fractures. In certain situations where pelvis fracture is associated with open wound, infection, abdominal injury or bladder injury - internal fixation with plate is contraindicated. Conventionally, external fixation is done in such cases. However, External Fixation is associated with pin tract infection, pin loosening, difficult wound care and less patient compliance. The present study was conducted to evaluate a possible 'middle path' between the two procedures. METHODS A prospective study was conducted from July 2017 to December 2019.18 adult patients with risk of infection were treated with INFIX. The patients' data was collected on presentation, preoperatively, intra-operatively and post operatively. The patients were followed up with serial radiographs. Functional status was assessed using Iowa Pelvis Score. After radiological union, implant removal was performed. The patients were followed up for a minimum of 6 months after the removal surgery. RESULTS The average age of patients in present study was 39.55 years with a male predominance. 16 out of 18 patients were polytrauma cases with ISS more than 15.50% patients had Lateral Compression type of fracture. Radiological union was seen at an average of 3.5 months. After removal, 78% patients had excellent outcome and 22% patients had good outcome. The complications observed were LFCN irritation (27.78%) and asymptomatic heterotopic ossification (22%). CONCLUSION Present study concludes that INFIX produces excellent outcome in pelvis fractures with risk of infection where anterior plating is contraindicated.

Association between Young-Burgess pelvic ring injury classification and concomitant injuries requiring urgent intervention. J Clin Orthop Trauma 2020; 11:1099-1103. [PMID: 33192014 PMCID: PMC7656475 DOI: 10.1016/j.jcot.2020.08.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 08/03/2020] [Accepted: 08/17/2020] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Young-Burgess classification (YB) is a mechanistic system which classifies pelvic ring injuries into anterior-posterior compression (APC), lateral compression (LC), vertical shear (VS) injuries, and combined mechanism (CM). The objective of this study was to identify associated injuries which require urgent operative intervention by YB classification. We hypothesize that YB classification is associated with 1) need for urgent intervention for pelvic fracture-related hemorrhage and 2) patterns of injury complexes requiring surgery. METHODS This is a retrospective study of severely injured trauma patients with pelvic ring injuries who presented to an urban Level-1 trauma center from 2007 to 2017. Associated injuries and procedures were determined by Abbreviated Injury Scale (AIS) and ICD-9/10 codes. YB classes were compared, followed by a cluster analysis to identify injury patterns and association with YB classifications. RESULTS Overall, 135 patients were included. 98 (72%) of patients presented with LC, 16 (12%) with APC, 8 (6%) with VS, and 13 (10%) with CM. VS and APC groups had higher rates of REBOA use compared to LC and CM groups (38% and 31% versus 11% and 0%, respectively, p = 0.01). The CM group, compared to LC, APC, and VS, had higher rates of urgent operative intervention for bleeding control (69% versus 32%, 50% and 43%, respectively, p = 0.01). 39 (29%) patients had a concomitant injury which was identified by CT scan in initial trauma work up and altered management, 46% which merited urgent intervention. On cluster analysis, there were no distinct injury complexes which required urgent operative intervention by YB class. CONCLUSIONS These data failed to identify unique injury complexes which merit urgent operative intervention by YB class. Nearly one in four patients had injuries identified by initial CT imaging which altered initial management, demonstrating the importance of early, full body CT imaging in severely injured patients with pelvic ring injuries.

Bilateral Symmetric Fracture of the Iliac Wings: An Unusual Situation after a Car Accident. Case Rep Orthop 2019; 2019:7942904. [PMID: 31781456 PMCID: PMC6855052 DOI: 10.1155/2019/7942904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Accepted: 09/27/2019] [Indexed: 11/29/2022] Open
Abstract
Introduction Pediatric pelvic fractures are uncommon and are usually the result of a high-energy mechanism. Bilateral symmetric fracture of the iliac bone is an extremely uncommon clinical entity that is not yet classified in the current classification systems of pelvic fractures. It mostly occurs among young patients with a history of a seat-belt injury. Patients usually complain of severe hip pain after an accident. Case Report A 5-year-old male was transported to our hospital after a car accident. He was complaining of vague pain in the pelvic region after he was exposed to an acceleration-deceleration trauma, seated in a children's car seat. Radiograph of the pelvis revealed a rare image of bilateral symmetric iliac fractures. Iliac bone fracture was suspected, which was also evident on pelvis and hip magnetic resonance imaging. Additional ultrasound of the abdomen was negative. He was hospitalized for observation, and after one day, he could be discharged from the hospital without complications. Policlinic control after three, six, and ten weeks showed favorable clinical and radiographic evolution. Conclusion Physicians should be aware of our report, which highlights a patient with the rare clinical condition of a bilateral symmetric fracture of the iliac bone after an acceleration-deceleration trauma. The differential diagnosis of acute hip pain should be considered for young patients. Always keep in mind additional injuries because of the high-energy trauma.

Abstract
CASE Vertically unstable pelvic ring injuries are often associated with sacroiliac (SI) joint subluxations or dislocations. The following report describes an irreducible SI joint dislocation where the ilium was locked in a position superior to the sacrum. This injury was refractory to initial closed reduction techniques and ultimately required an open reduction. CONCLUSIONS This report demonstrates the limitations of closed manipulation for some vertically unstable pelvic ring injuries. It is critical to have a strong understanding of the anatomy and typical manipulations to succeed in both closed and open SI joint reduction attempts.

Abstract
BACKGROUND Subcutaneous fixation of the anterior pelvic ring is an emerging surgical technique for trauma patients. The aim of this study was to biomechanically evaluate 2 internal fixation devices for stabilizing a disrupted pelvic ring and compare them with traditional external fixation. METHODS Thirty-six synthetic pelvises with a simulated unstable ring fracture (anteroposterior compression type III) were divided into 3 groups. Group A underwent fixation with a supra-acetabular external fixator; group B, with an internal fixator using the USS II polyaxial system; and group C, with an internal fixator using the Click'X polyaxial system. Biomechanical testing included measurement of peak-to-peak displacement at 300, 400, and 500 N; total displacement; plastic deformation; stiffness; and fracture-line displacement. RESULTS Statistical analysis of all measured parameters revealed no significant differences among the groups. However, vertical displacement of the preshaped connecting rod within the screw heads occurred as a result of inadequate stability of the internal fixation at the rod-screw interface. CONCLUSIONS Although internal fixator devices are placed close to the bone and should therefore maintain greater stiffness, our data did not support the hypothesis of superior stability. Special attention is required when using a curved connecting rod as the rod is easily displaced, placing relevant anatomical structures at risk. These devices require further refinement to avoid potential patient injury.

Outcomes of Pediatric Pelvic Fractures: A Level I Trauma Center's 20-Year Experience. J Surg Res 2019; 243:515-523.

Abstract
BACKGROUND Pediatric pelvic fractures are rare. The contribution of pelvic fracture pattern, risk factors for associated injuries, and mortality are poorly defined in this population. METHODS Patients aged 0-17 with pelvic fractures at a level I trauma center over a 20-y period were reviewed. Fracture patterns were classified according to the Young-Burgess classification when applicable. Fractures were analyzed for location, pubic symphysis or sacroiliac widening, and contrast extravasation. RESULTS There were 163 pelvic fractures in 8758 admissions (incidence 2%). The most common associated injures were extremity fractures (60%, n = 98), abdominal solid organ (55%, n = 89), and chest (48%, n = 78), with the majority (61%, n = 99) sustaining injuries to multiple organs. Unstable fractures were associated with injures to the thorax (70% versus 40%), heart (15% versus 2%), and spleen (40% versus 18%), all P < 0.05. Nonpelvic operative interventions were required in 45% (n = 73) and were more common in unstable fractures (36% versus 19%), contrast extravasation (63% versus 26%), sacroiliac widening (36% versus 20%), and sacral fractures (39% versus 13%), all P < 0.05. Mortality was 13% and higher in males versus females (18% versus 5%), contrast extravasation (50% versus 3%), or sacroiliac/pubic symphysis widening (13% versus 2%) (all P < 0.05). Male gender (OR 6.03), brain injury (OR 6.18), spine injury (OR 5.06), and cardiac injury (OR 35.0) were independently associated with mortality (all P < 0.05). CONCLUSIONS Pediatric pelvic fractures are rare but critical injuries associated with significant morbidity and need for interventions. Increasing fracture severity corresponds to injuries to other body systems and increased mortality.

Abstract
INTRODUCTION Pelvic fragility fractures (PFF) are common in older people and associated with a significant burden of mortality and morbidity. This is related to the challenges of appropriate pain control and early mobilisation. The current standard for treatment of PFF is non-surgical management. Minimally invasive surgical techniques for sacral fracture stabilisation have been shown to improve outcomes in terms of pain control and mobility, and they are safe. Randomised controlled trials are required before recommendations can be made for surgical management of PFF to become the new standard of care. This feasibility study will explore several uncertainties around conducting such a trial. METHODS AND ANALYSIS ASSERT (Acute Sacral inSufficiEncy fractuRe augmenTation) is a single-site randomised controlled, parallel-arm, feasibility trial of surgical stabilisation versus non-surgical management of acute sacral fragility fractures in people aged 70 years and over. Patients will be randomised to either surgical or non-surgical group on a 1:1 ratio. Follow-up of participants will occur at 2, 4 and 12 weeks with safety data collected at 52 weeks. Primary objectives are to determine feasibility and design of a future trial, including outcomes on recruitment, adherence to randomisation and safety. This will be supplemented with a qualitative interview study of participants and clinicians. Secondary objectives will inform study design procedures to determine clinical and economic outcomes between groups, including scored questionnaires, analgesia requirements, resource use and quality of life data. Data analysis will be largely descriptive to inform outcomes and future sample size. ETHICS AND DISSEMINATION Ethical approval was granted by the North East Newcastle and North Tyneside 2 Research Ethics Committee (reference 18/NE/0212). ASSERT was approved and sponsored by Nottingham University Hospitals NHS Trust (reference 18HC001) and the Health Research Authority (reference IRAS 232791). Recruitment is ongoing. Results will be presented at relevant conferences and submitted to appropriate journals on study completion. TRIAL REGISTRATION NUMBER ISRCTN16719542; Pre-results.

Abstract
BACKGROUND Complex pelvic fractures present the orthopaedic surgeon with many challenges. 3-D printed models may provide assistance in pre-operative planning, may lead to improvements in intra-operative (i) decision making and (ii) efficiencies (time reduction, blood loss reduction, screening reduction) and may result in improvements in post-operative outcomes (fracture reduction & quality of life). The models also provide hands-on opportunities for orthopaedic trainees and patients. This may result in improvements in (i) education/training regarding the management of pelvic and acetabular fractures for orthopaedic trainees and (ii) improvements in patient consenting and overall patient satisfaction. DESIGN Single-centre, two orthopaedic surgeons (pelvic and acetabular fellowship trained), prospective observational study. Twenty patients with acute displaced pelvic/acetabular fracture(s); ten 3-D-printed pelvis and ten non-printed cases for comparison. The comparison cohorts were matched for fracture classification, sex and age. OUTCOME MEASURES Classification assistance, intra-operative time, estimated blood loss, screening amount, post-operative reduction and infection, EQ-5D-5L, teaching/educational assistance and pre-operative counselling. RESULTS The models provided more information regarding fracture pattern, however, this did not result in change of CT-planned approach/procedure or patient outcomes. The models scored highly on surgeon's questionnaire. The models were found to have a positive impact on trainee education and patient consenting/counselling. With regard to objective comparisons, there was no significant improvements in time-to-surgery, intra-operative time, estimated blood loss, screening amount, fracture reduction or infection rate. There was no significant difference in quality of life questionnaire ~ 12 months post-surgery (statistical tests used; Cohen's effect size and Fisher's exact test). CONCLUSIONS Whilst the authors recognize the positive subjective findings with respect to the use of 3-D printing in pelvic and acetabular trauma in our National Centre, objective findings were lacking.
