Meuser AH, Henyš P, Höch A, Gänsslen A, Hammer N. Evaluating the stability of external fixators following pelvic injury: A systematic review of biomechanical testing methods. J Mech Behav Biomed Mater 2024; 153:106488. [PMID: 38437754 DOI: 10.1016/j.jmbbm.2024.106488] [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: 05/25/2023] [Revised: 10/31/2023] [Accepted: 02/26/2024] [Indexed: 03/06/2024]
Abstract
INTRODUCTION This systematic review aims to identify previously used techniques in biomechanics to assess pelvic instability following pelvic injury, focusing on external fixation constructs. METHODS A systematic literature search was conducted to include biomechanical studies and to exclude clinical trials. RESULTS Of an initial 4666 studies found, 38 met the inclusion criteria. 84% of the included studies were retrieved from PubMed, Scopus, and Web of Science. The studies analysed 106 postmortem specimens, 154 synthetic bones, and 103 computational models. Most specimens were male (97% synthetic, 70% postmortem specimens). Both the type of injury and the classification system employed varied across studies. About 82% of the injuries assessed were of type C. Two different fixators were tested for FFPII and type A injury, five for type B injury, and fifteen for type C injury. Large variability was observed for external fixation constructs concerning device type and configuration, pin size, and geometry. Biomechanical studies deployed various methods to assess injury displacement, deformation, stiffness, and motion. Thereby, loading protocols differed and inconsistent definitions of failure were determined. Measurement techniques applied in biomechanical test setups included strain gauges, force transducers, and motion tracking techniques. DISCUSSION AND CONCLUSION An ideal fixation method should be safe, stable, non-obstructive, and have low complication rates. Although biomechanical testing should ensure that the load applied during testing is representative of a physiological load, a high degree of variability was found in the current literature in both the loading and measurement equipment. The lack of a standardised test design for fixation constructs in pelvic injuries across the studies challenges comparisons between them. When interpreting the results of biomechanical studies, it seems crucial to consider the limitations in cross-study comparability, with implications on their applicability to the clinical setting.

A short decision time for transcatheter embolization can better associate mortality in patients with pelvic fracture: a retrospective study. Front Med (Lausanne) 2024; 10:1329167. [PMID: 38259838 PMCID: PMC10800860 DOI: 10.3389/fmed.2023.1329167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Accepted: 12/15/2023] [Indexed: 01/24/2024] Open
Abstract
Background Early use of hemostasis strategies, transcatheter arterial embolization (TAE) is critical in cases of pelvic injury because of the risk of hemorrhagic shock and other fatal injuries. We investigated the influence of delays in TAE administration on mortality. Methods Patients admitted to the Advanced Critical Care Center at Gifu University with pelvic injury between January 2008 and December 2019, and who underwent acute TAE, were retrospectively enrolled. The time from when the doctor decided to administer TAE to the start of TAE (needling time) was defined as "decision-TAE time." Results We included 158 patients, of whom 23 patients died. The median decision-TAE time was 59.5 min. Kaplan-Meier curves for overall survival were compared between patients with decision-TAE time above and below the median cutoff value; survival was significantly better for patients with values below the median cutoff value (p = 0.020). Multivariable Cox proportional hazards regression analysis revealed that the longer the decision-TAE time, the higher the risk of mortality (p = 0.031). TAE duration modified the association between decision-TAE time and overall survival (p = 0.109), as shorter TAE duration (procedure time) was associated with the best survival rate (p for interaction = 0.109). Conclusion Decision-TAE time may play a key role in establishing resuscitation procedures in patients with pelvic fracture, and efforts to shorten this time should be pursued.

Comparison of sacroiliac screw techniques for unstable sacroiliac joint disruptions: a finite element model analysis. Injury 2023; 54 Suppl 6:110783. [PMID: 38143127 DOI: 10.1016/j.injury.2023.05.014] [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: 02/28/2023] [Revised: 04/25/2023] [Accepted: 05/01/2023] [Indexed: 12/26/2023]
Abstract
Vertically unstable pelvic injuries associated with sacroiliac disruption are challenging. Although percutaneous iliosacral fixation using two screws at S1 vertebral body has been shown beneficial, the use of two transiliac screws at S1 has been proposed to increase the fixation strength of the construct. In the herein study, the finite element method (FEM) was performed to analyse the biomechanical behaviour of five different constructions using iliosacral screws only, transiliac screws only, and combining an iliosacral and a transiliac screw. A vertically unstable AO 61C1.2 type pelvic injury was produced for the evaluation of the posterior pelvic displacement and implant stress, and the anterior implant stress using FEM. The symphysis pubis was fixed with a 3.5-mm reconstruction plate in all cases. The model was axially loaded with 800N applied in the centre of S1 body, perpendicular to the ground (Y-axis), simulating the bipodal stance moment. There was a statistically significant reduction in both posterior displacement and implant stresses in the groups fixed with at least one transiliac screw compared to the groups fixed with iliosacral screws. In our FEM study, the construct using two transiliac screws in S1 is biomechanically superior for stabilizing the sacroiliac joint in vertically unstable pelvic ring injuries compared to the other configurations. Lateral displacement, posterior displacement, and von Mises stress were reduced with this construct. A good option can be the use of one iliosacral screw and one transiliac screw in S1.

Abstract
Determining the true availability of resources and understanding the level of training of surgeons involved in the treatment of patients with pelvic fractures and haemorrhagic shock is critical. In the herein study, the availability of technical, technological, and human resources for the care of this injury in Latin America region was analysed, and the preferences of orthopaedic trauma surgeons when performing interventions for the diagnosis and treatment of patients with pelvic trauma and associated haemorrhagic shock was described. A cross sectional web-based survey containing questions on knowledge, attitudes, and practices with respect to imaging resources, emergency pelvic stabilization methods, and interventions used for bleeding control was sent to 948 Latin America orthopaedic trauma surgeons treating pelvic fractures in the emergency department. Differences between regional clusters, level of training, type of hospital, and pelvic surgery volume were assessed. 368 responses were obtained, with 37.5% of respondents reporting formal training in pelvic surgery and 36.0% having available protocol for managing these patients. The most frequently used interventions were the supra-acetabular pelvic external fixator and pelvic packing. Limited hospital and imaging resources are available for the care of patients with pelvic trauma and associated haemorrhagic shock throughout Latin America. In addition, the training of orthopaedic trauma surgeons dealing with this type of injury and the volume of pelvic surgeries per year is heterogeneous. It should be urgently considered to develop management protocols adapted to Latin America according to the availability of resources, as well as to promote training in this severe life-threatening traumatic condition.

Abstract
BACKGROUND Unstable pelvic fractures, especially vertical shear fractures, require surgery for correct reduction, rigid fixation, and improved postoperative outcomes. Herein, we assess the effectiveness of our minimally invasive procedure for the management of unstable pelvic fractures. HYPOTHESIS We hypothesized that this procedure would be useful for the management of unstable pelvic fractures. PATIENTS AND METHODS This study included 28 patients with unstable pelvic fractures (vertical shear injuries; AO types C1-3) treated using minimally invasive surgery for spinopelvic fixation (MIS-SP) between 2014 and 2020 (mean follow-up time, 15 months). The MIS-SP requires four percutaneous pedicle screws and four iliac screw insertions. Subsequently, reduction and fixation are performed. RESULTS The mean preoperative displacement of the posterior pelvic elements in craniocaudal correction was 17.6 (range, 9.0-32.2) mm. The mean length of the craniocaudal reduction was 16.5 (8.1-30.1) mm, with a mean reduction rate of 93.5% (78%-100%). The mean length of the mediolateral reduction was 11.3 (3.9-19.6) mm, with a mean reduction rate of 87.3% (76%-100%). DISCUSSION Our novel reduction and fixation procedure is a powerful, minimally invasive option for the treatment of unstable pelvic ring fractures. LEVEL OF EVIDENCE III.

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
PURPOSE Pelvic ring fractures (PRFs) management needs adequate facilities and human resources. However, the prehospital ambulance management role in Indonesia is insufficient. Many hospitals have limited resources that necessitate patients to be referred to higher trauma centers. This study aims to describe the state of PRFs management at a level 1 trauma center in limited-resource country. METHODS We conducted retrospective studies of PRFs management from 2011 to 2021 at Cipto Mangunkusumo Hospital. We analyzed patient's management flow from injury, referral process, initial to definitive treatment, mortality, and Majeed functional score. RESULTS From 109 patients, 30.3% were non-referrals that came without ambulance, while 69.7% were referrals using an ambulance. All non-referral patients came without pelvic binder with 54.5% unstable hemodynamic, while 35.5% of the referrals came with unstable hemodynamic and 72.4% had pelvic binder. Median time for non-referrals reaching our hospital is 12.5 h. Unlike local referrals, 75% of regional and 85.7% of national referrals general improvement had to be improved before being referred. Polytrauma cases were 33.9% with 12 days mean interval to definitive treatment. Mortality rate in this study was 13.8%. During post-operative follow-up with a mean of 4 years, 83% of patients could be followed up and reported 93 median Majeed score. CONCLUSION The management of PRFs at level 1 trauma center in limited-resource country shows a mortality rate of 13.8% through various limitations such as unimplemented ambulance prehospital management, number of patients who were referred without pelvic binder applied, and the long waiting interval for definitive treatment.

Zakirov RI, Akhtyamov IF. Substantation of the method of lumbo-pelvic fixation in verically unstable fractures of the sacrum. BULLETIN OF THE MEDICAL INSTITUTE "REAVIZ" (REHABILITATION, DOCTOR AND HEALTH) 2022. [DOI: 10.20340/vmi-rvz.2022.5.clin.6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/07/2022]
Abstract
Background. According to the literature and our own observations, there is an increase in the number of victims of young, able-bodied age with severe injuries to the pelvic structures. Despite numerous developments and studies in this area, high mortality and a high percentage of unsatisfactory treatment results remain. The publication reflects the advantages of using bilateral lumbopelvic fixation in the treatment of injuries to the cross. Load calculation, biomechanical modeling of damages and displacing factors are presented. Bilateral lumbopelvic fixation has proven to be a reliable method capable of providing reliable fixation of the fracture at all stages of treatment. Aim. To substantiate and test modified lumbopelvic stabilization of the pelvic ring in patients with vertically unstable (C1-2-3 according to Tile M.) sacral fractures. Material and methods. Based on the treatment of 20 patients with severe sacral fractures, it was proved that the best result was achieved with bilateral lumbopelvic stabilization. The use of the author's version (RF Patent No. 2684870 "Method of fixation in unilateral unstable sacral fractures") of osteosynthesis is presented on the example of the treatment of multiple pelvic trauma, a good clinical result was obtained, and neurological symptoms were stopped. Results. Lumbar-iliac osteosynthesis for vertically unstable sacral fractures is the optimal method of fixation. The distribution vector of the levers of the latch corresponds to the biasing force, which ensures maximum reliability of the synthesis. The method, if necessary, creates conditions for decompression of the roots, prevents the early development of arthrosis of the sacroiliac joints. Using it allows you to maintain or correct the sagittal and frontal balance of the spine. The use of bilateral 8-screw lumboiliac fixation with the installation of a transverse tie is recommended, since unilateral fixation or a decrease in the number of fixing elements can lead to loosening of the fixator. Conclusion. Based on biomechanical modeling and the results of treatment of patients with severe injuries of the posterior pelvic ring, the effectiveness of the proposed method of lumbopelvic fixation was proven.

[PMID: 34874811 PMCID: PMC9309190 DOI: 10.1080/10903127.2021.2015024] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 11/17/2021] [Accepted: 11/30/2021] [Indexed: 01/07/2023]
Abstract
OBJECTIVE Widespread adoption of prehospital pelvic circumferential compression devices (PCCDs) by emergency medical services (EMS) systems has been slow and variable across the United States. We sought to determine the frequency of prehospital PCCD use by EMS providers. Secondarily, we hypothesized that prehospital PCCD use would improve early hemorrhagic shock outcomes. METHODS We conducted a single-center retrospective cohort study of 162 unstable pelvic ring injuries transported directly to our center by EMS from 2011 to 2020. Included patients received a PCCD during their resuscitation (prehospital or emergency department). Prehospital treatment details were obtained from the EMS medical record. The primary outcome was the proportion of patients who received a PCCD by EMS before hospital arrival. Secondarily, we explored factors associated with receiving a prehospital PCCD, and its association with changes in vital signs, blood transfusion, and mortality. RESULTS EMS providers documented suspicion of a pelvic ring fracture in 85 (52.8%) patients and 52 patients in the cohort (32.2%) received a prehospital PCCD. Wide variation in prehospital PCCD use was observed based on patient characteristics, geographic location, and EMS provider level. Helicopter flight paramedics applied a prehospital PCCD in 46% of the patients they transported (38/83); in contrast, the EMS organizations geographically closest to our hospital applied a PCCD in ≤5% of cases (2/47). Other predictors associated with receiving a prehospital PCCD included lower body mass index (p = 0.005), longer prehospital duration (p = 0.001) and lower Injury Severity Score (p < 0.05). We were unable to identify any improvements in clinical outcomes associated with prehospital PCCD, including early vital signs, number of blood transfusions within 24 hours, or mortality during admission (p > 0.05). CONCLUSION Our results demonstrate wide practice variation in the application of prehospital PCCDs. Although disparate PCCD application across the state is likely explained by differences across EMS organizations and provider levels, our study was unable to identify any clinical benefits to the prehospital use of PCCDs. It is possible that the benefits of a prehospital PCCD can only be observed in the most displaced fracture patterns with the greatest early hemodynamic instability.

[PMID: 33745761 PMCID: PMC8173585 DOI: 10.1016/j.cjtee.2021.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Revised: 02/11/2021] [Accepted: 02/28/2021] [Indexed: 02/04/2023] Open
Abstract
PURPOSE Pelvic fractures are characterized by high energy injuries and often accompanied with abdominal and pelvic organ injury. CT has been applied for several decades to evaluate blunt pelvic trauma patients. However, it has a certain rate of inaccurate diagnosis of abdominal hollow viscus injury (HVI), especially in the early stage after injury. The delayed diagnosis of HVI could result in a high morbidity and mortality. The bowel injury prediction score (BIPS) applied 3 clinical variables to determine whether an early surgical intervention for blunt HVI was necessary. We recently found another clinical variable (iliac ecchymosis, IE) which appeared at the early stage of injury, could be predicted for HVI. The main objective of this study was to explore the novel combination of IE and BIPS to enhance the early diagnosis rate of HVI, and thus reduce complications and mortalities. METHODS We conducted a retrospective analysis from January 2008 to December 2018 and recorded blunt pelvic trauma patients in our hospital. The inclusion criteria were patients who were verified with pelvic fractures using abdomen and pelvis CT scan in the emergency department before any surgical intervention. The exclusion criteria were abdominal CT insufficiency before operation, abdominal surgery before CT scan, and CT mesenteric injury grade being 5. The MBIPS was defined as BIPS plus IE, which was calculated according to 4 variables: white blood cell counts of 17.0 or greater, abdominal tenderness, CT scan grade for mesenteric injury of 4 or higher, and the location of IE. Each clinical variable counted 1 score, totally 4 scores. The location and severity of IE was also noted. RESULTS In total, 635 cases were hospitalized and 62 patients were enrolled in this study. Of these included patients, 77.4% (40 males and 8 females) were operated by exploratory laparotomy and 22.6% (8 males and 6 females) were treated conservatively. In the 48 patients underwent surgical intervention, 46 were confirmed with HVI (45 with IE and 1 without IE). In 46 patients confirmed without HVI, only 3 patients had IE and the rest had no IE. The sensitivity and specificity of IE in predicting HVI was calculated as 97.8% (45/46) and 81.3% (13/16), respectively. The median MBIPS score for surgery group was 2, while 0 for the conservative treatment group. The incidence of HVI in patients with MBIPS score ≥ 2 was significantly higher than that in patients with MBIPS score less than ≤ 2 (OR = 17.3, p < 0.001). CONCLUSION IE can be recognized as an indirect sign of HVI because of the high sensitivity and specificity, which is a valuable sign for HVI in blunt pelvic trauma patients. MBIPS can be used to predict HVI in blunt pelvic trauma patients. When the MBIPS score is ≥ 2, HVI is strongly suggested.
