Early fixation strategies for high energy pelvic ring injuries - the Zurich algorithm

Effectiveness of a pelvic Binder-Only protocol for early stabilization in hemodynamically unstable pelvic ring injuries

BACKGROUND

Hemodynamically unstable pelvic ring injuries pose significant challenges in trauma care. Although external fixation is traditionally used for initial stabilization, pelvic binders have emerged as potential alternatives. Therefore, this study aimed to evaluate the feasibility and safety of maintaining pelvic binders alone as a temporary stabilization method in patients with hemodynamically unstable pelvic ring injuries.

METHODS

This retrospective cohort study included 114 patients with hemodynamically unstable pelvic ring injuries treated at two Level 1 trauma centers. The patients were divided into two groups: Binder-Only (n = 53) and External Fixation (n = 61). Outcomes including complications, intensive care unit (ICU) length of stay, and mechanical ventilation duration were compared.

RESULTS

Baseline characteristics and injury severity were comparable between the two groups. There were no significant differences in complication rates (22.6% vs. 26.2%, p = 0.657), ICU length of stay (8 [3-16] vs. 10 [6-19] days, p = 0.257), or mechanical ventilation duration (3 [1-6] vs. 5 [2-9] days, p = 0.098) between the Binder-Only and External Fixation groups. The Binder-Only group achieved anterior fixation earlier than the External Fixation group (2 [1-2] vs. 4 [2-5] days, p < 0.001). Logistic regression analysis confirmed that group allocation was not associated with complications. The independent predictors of complications included diabetes mellitus, initial lactate level, and packed red blood cells transfusion within 4 h.

CONCLUSIONS

Pelvic binders provide sufficient temporary stabilization in hemodynamically unstable pelvic ring injuries, with outcomes comparable to those of external fixation. This strategy offers a practical alternative that avoids the complications and logistical challenges associated with external fixation.

Future directions in the treatment of pelvic fractures with abdominal organ injury: the potential of combined endovascular embolization and external fixation techniques

Pelvic fractures with abdominal organ injuries are complex and life-threatening conditions that pose significant challenges in trauma care. Current management strategies, including external fixation and interventional radiology techniques such as embolization, have shown promise in stabilizing the pelvis and controlling hemorrhage. However, these approaches face challenges such as the lack of standardized protocols, variability in patient selection, and the need for robust multidisciplinary collaboration. Additionally, the combined use of these modalities may lead to improved outcomes, including reduced mortality and shorter hospital stays, but further research is needed to optimize their application. This review aims to comprehensively explore the potential synergies between endovascular embolization and external fixation in managing these complex injuries. It critically assesses the latest clinical evidence, identifies gaps in current practices, and proposes future directions to enhance treatment effectiveness and patient outcomes.

Pelvic ring fracture and erectile dysfunction (PERFECD) - 3 year follow-up cross sectional study

INTRODUCTION

Pelvic ring fractures are known to be associated with complications associated with adjacent organ injuries, such as the urogenital tract (e.g. erectile dysfunction (ED), which are sometimes diagnosed in a delayed fashion. Therefore, we assessed the quality of life (QoL) and the rate of erectile dysfunction (ED) following pelvic ring fractures at a minimum of 3 years after pelvic ring injury.

METHODS

Between January 1, 2016, and December 31, 2020, adult male patients (≥ 18 years) with pelvic ring injuries were included in the study. Fractures were classified according to the Young & Burgess (Y&B) classification system, while pelvic contusions were categorized as the control group. Data were collected using a written questionnaire that assessed Quality of Life (QoL) by Short Form 12 (SF-12) and erectile dysfunction (ED) with the International Index of Erectile Function 5 (IIEF-5). ED was stratified as follows: no ED (21-25 points), mild ED (16-21 points), moderate ED (9-15 points), and severe ED (5-7 points). Comorbidities and risk factors for ED were also assessed, including vasculopathy, peripheral artery disease, hypercholesterolemia, coronary artery disease, diabetes, and smoking.

RESULTS

A total of 182 patients were included, with a mean age at injury of 53.5 years (SD 17.1) and a mean age at the time of the questionnaire of 57.8 years (SD 17.4). The distribution of patients was as follows: APC Group (n = 20, 11.1%), LC Group (n = 94, 52.2%), CMVS Group (n = 6, 3.3%), and Control Group (n = 60, 33.3%). The mean Injury Severity Score (ISS) was 24.6 points (SD 16.4). Regarding erectile dysfunction, 8 patients (17.4%) had no ED, 10 (21.7%) had mild ED, 6 (13.0%) had moderate ED, and 22 (47.8%) had severe ED. Quality of Life (QoL) was significantly reduced in patients with CMVS pelvic fractures, particularly in physical role function, which scored 62.5 points (SD 29.6, p < 0.001). All patients in the APC Group reported at least a mild form of ED. APC injuries were identified as an independent risk factor for lower IIEF-5 scores (OR -4.5, 95% CI -8.3 to -0.7, p = 0.02), comparable to other risk factors such as hypertension (OR -9.2, 95% CI -12.8 to -5.6, p < 0.001), diabetes (OR -5.3, 95% CI -9.4 to -1.2, p = 0.012), and smoking (OR -2.6, 95% CI -5.2 to -0.04, p = 0.05).

CONCLUSION

Vertical shear fractures are associated with significantly lower quality of life compared to APC or LC fractures three years post-injury. The APC type of pelvic ring injury was identified as an independent risk factor for the development of erectile dysfunction (ED). Early screening and appropriate management should be initiated for patients with APC injuries to address and mitigate the risk of ED.

Evolution of management strategies for unstable pelvic ring injuries over the past 40 years: a systematic review

BACKGROUND

Hemodynamically unstable pelvic ring fractures from high-energy trauma are critical injuries in trauma care, requiring urgent intervention and precise diagnostics. With ongoing advancements in trauma management, treatment strategies have evolved, with some techniques becoming obsolete as new ones emerge. This study aimed to evaluate changes and trends in treatment algorithms for these injuries over approximately 40 years.

METHODS

A systematic review of PubMed and EMBASE was conducted to include articles published over roughly four decades that presented visual treatment algorithms or workflows for managing unstable pelvic ring fractures. Identified algorithms were categorized by publication period and analyzed by initial assessment, diagnostic methods, pelvic stabilization, and hemorrhage control interventions.

RESULTS

The search identified 5,434 publications, of which 32 met the inclusion criteria. 75% of these studies were published between 2011 and 2022, reflecting a growing focus on standardization, particularly in Europe, North America, and Asia. Physiological assessment remains essential in the initial management of hemodynamically unstable pelvic ring fractures, guiding resuscitation and influencing the selection of intervention and imaging. The use of pelvic binders or sheets has risen steadily, highlighting their role in hemorrhage control and temporary stabilization. CT scans and angiography have largely replaced pelvic X-rays in diagnostic protocols, becoming preferred radiological methods alongside focused assessment with sonography for trauma (FAST). Pelvic stabilization remains critical, with external fixation being the most commonly used technique, showing an upward trend in recent years. Laparotomy, pelvic packing, and angioembolization continue to play vital roles in hemorrhage management. Emerging techniques, such as resuscitative endovascular balloon occlusion of the aorta (REBOA), anterior subcutaneous internal fixation (INFIX), and rescue screws, are increasingly included in treatment algorithms, while diagnostic peritoneal lavage (DPL) has become obsolete and is no longer listed in these algorithms.

CONCLUSIONS

This review provides foundational insights toward the standardization of initial treatment for hemodynamically unstable pelvic ring fractures and holds significant importance in enhancing the consistency and efficiency of treatment. Future research should focus on accumulating higher-quality evidence to evaluate the effectiveness of standardized protocols and explore the applicability of new treatment methods.

Efficacy and outcomes of rescue screws in unstable pelvic ring injuries - A retrospective matched cohort study

PURPOSE

The emergency treatment of unstable pelvic ring injuries is still a challenge and requires surgical and anesthesiological resuscitation. Emergency fixation of the unstable pelvic ring with percutaneous sacroiliac (SI) screws, also known as "Rescue Screws", is an established treatment method. The aim of our study was to compare the outcome and complication rates of "Rescue Screws" with elective SI-screw fixations.

METHODS

A 1:1 ratio nearest-neighbor matched, retrospective cohort study of trauma patients with acute pelvic ring injuries at a level one trauma center was performed. Patients ≥ 15 years, treated with SI-screw fixation were included.

EXCLUSION CRITERIA

pathologic fractures, missing consent and navigated procedures. The primary outcome parameters was defined as SI-screw revision operations. Patients were stratified according to treatment strategy (RS: Rescue Screws; EL: elective SI-screws).

RESULTS

From 392 patients identified between 11/2014 and 08/2021, 186 met the inclusion criteria with 41 in the RS Group and 145 in the EL group. After matching, 41 patients were included in each group with similar baseline characteristics except persistent hemodynamic shock (RS: n = 22 (53.37%) vs. EL: n = 1 (4.3%), p < 0.001). Surgical characteristics were comparable in terms of instrumentation levels and insertion-sites. No significant differences were observed in the outcome parameters (revisions, reoperations, implant-associated complications, LOS and mortality) between both groups.

CONCLUSION

Treatment of unstable pelvic ring fractures with Rescue Screws appears as a feasible treatment option for emergency stabilization. Rescue Screws are not associated with elevated revision rates and increased complications rates. This minimally invasive technique enables safe emergency stabilization of the posterior pelvic ring. Prospective or randomized clinical trials are required to directly compare Rescue Screws with other competing emergency stabilization techniques.

Limb salvage in traumatic hemipelvectomy: case series with surgical management and review of the literature

BACKGROUND

Traumatic hemipelvectomies are rare and serious injuries. The surgical management was described in several case studies, with primary amputation often performed to save the patient's life.

METHODS

We report of two survivors with complete traumatic hemipelvectomy resulting in ischemia and paralyzed lower extremity. Due to modern emergency medicine and reconstructive surgery, limb salvage could be attained. Long-term outcome with quality of life was assessed one year after the initial accident.

RESULTS AND CONCLUSIONS

The patients were able to mobilize themselves and live an independent life. The extremities remained without function and sensation. Urinary continence and sexual function were present and the colostomy could be relocated in both patients. Both patients support limb salvage, even having difficulties and follow-up treatments. Concomitant cases are required to consolidate the findings.

Standard practice in the treatment of unstable pelvic ring injuries: an international survey

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.

Performance Assessment of Out-of-Hospital Use of Pelvic Circumferential Compression Devices for Severely Injured Patients in Switzerland: A Nationwide Retrospective Cross-Sectional Study

BACKGROUND

Patients with severe pelvic fractures carry a greater risk of severe bleeding, and pelvic compression devices (PCCD) are used to stabilize the pelvis on the pre-hospital scene. The aim of this study was to describe the use of PCCD in the pre-hospital setting on a nationwide scale (Switzerland) and determine the sensitivity, specificity and rates of over- and under-triage of the current application practices. The secondary objective was to identify pre-hospital factors associated with unstable pelvic fractures.

METHODS

Retrospective cross-sectional study using anonymized patient data (1 January 2015-31 December 2020) from the Swiss Trauma Registry (STR). Based on AIS scores, patients were assigned a unique principal diagnosis among three categories (unstable pelvic fracture-stable pelvic fracture-other) and assessed for use or not of PCCD. Secondarily, patient characteristics, initial pre-hospital vital signs, means of pre-hospital transport and trauma mechanism were also extracted from the database.

RESULTS

2790 patients were included for analysis. A PCCD was used in 387 (13.9%) patients. In the PCCD group, 176 (45.5%) had an unstable pelvic fracture, 52 (13.4%) a stable pelvic fracture and 159 (41.1%) an injury unrelated to the pelvic region. In the group who did not receive a PCCD, 214 (8.9%) had an unstable pelvic fracture, 182 (7.6%) a stable pelvic fracture and 2007 (83.5%) an injury unrelated to the pelvic region. The nationwide sensitivity of PCCD application was 45.1% (95% CI 40.1-50.2), the specificity 91.2% (95% CI 90-92.3), with both over- and under-triage rates of 55%. The prevalence of unstable fractures in our population was 14% (390/2790). We identified female sex, younger age, lower systolic blood pressure, higher shock index, pedestrian hit and fall ≥3 m as possible risk factors for an unstable pelvic fracture.

CONCLUSIONS

Our results demonstrate a nationwide both over- and under-triage rate of 55% for out-of-hospital PCCD application. Female gender, younger age, lower blood pressure, higher shock index, pedestrian hit and fall >3 m are possible risk factors for unstable pelvic fracture, but it remains unclear if those parameters are relevant clinically to perform pre-hospital triage.

Temporary bridging trans-hip external fixation in damage control orthopaedics treatment after severe combat trauma: A clinical case series

The role of external fixation in Damage Control Orthopaedics has been well described. Temporary external fixation has been recommended to provide relative bone stability while the soft tissue heals, prior to formal open reduction and internal fixation. Temporary bridging external fixation, that spans the joint, is recommended as primary skeletal stabilization in complex intra-articular and peri-articular fractures, in extensive peri-articular soft-tissue damage around the knee, ankle, elbow and wrist joints. Works devoted to temporary trans-hip external fixation in treatment of complex high-energy injuries are relatively rare. The purpose of this article is to present our experience in using temporary hip spanning external fixation during primary treatment of six patients suffered from complex open intra-articular and peri-articular fractures of the proximal femoral bone with extensive soft tissue damage due to war blast or high-velocity gunshot trauma. Primary management was based on the concept of Advanced Trauma Life Support and Damage Control Orthopaedics. Conversion to definitive bone reconstruction was performed on the next stage of the treatment after general and local stabilization.

Finite Element Analysis and Transiliac-Transsacral Screw Fixation for Posterior Pelvic Ring with Sacrum Dysplasia

OBJECTIVE

Posterior pelvic ring sacroiliac screws are preferred by clinicians for their good biomechanical performance. However, there are few studies on mechanical analysis and intraoperative screw insertion of the dysplastic sacrum and sacroiliac screw. This study investigated the biomechanical performance of oblique sacroiliac screws (OSS) in S1 combined with transiliac-transsacral screws (TTSs) in S2 for pelvic fracture or sacroiliac dislocation with dysplastic sacrum and evaluated the safety of screw placement assisted by the navigation template.

METHODS

Six models were established, including one OSS fixation in the S2 segment, one transverse sacroiliac screw (TSS) fixation in the S2 segment, one TTS fixation in the S2 segment, one OSS fixation in the S1 and S2 segments, one OSS fixation in the S1 segment and one TSS fixation in the S2 segment, one OSS fixation in the S1 segment and one TTS fixation in the S2 segment. Then, finite element analysis (FEA) was performed. Twelve dysplastic sacrum patients with pelvis fracture or sacroiliac dislocation underwent OSS insertion in the S1 combined with TTS insertion in the S2 under the assistance of the patient-specific locked navigation template. Grading and Matta scores were evaluated after surgery.

RESULTS

In the one-screw fixation group, the vertical displacements of the sacrum surface of S2 OSS, S2 TSS and S2 TTS were 1.23, 1.42, and 1.22 mm, respectively, and the maximum stress of screw were 139.45 MPa, 144.81 MPa, 126.14 MPa, respectively. In the two-screw fixation group, the vertical displacements of the sacrum surface of the S1 OSS + S2 OSS, S1 OSS + S2 TSS and S1 OSS + S2 TTS were 0.91, 1.06, and 0.75 mm, respectively, and the maximum stress of screw were 149.26 MPa, 167.13 Pa, 136.76 MPa, respectively. Clinically, a total of 12 TTS and OSS were inserted under the assistance of navigation templates, with a surgical time of 55 ± 7.69 min, bleeding of 57.5 ± 18.15 ml and radiation times of 14.5 ± 4.95. One of the TTS and one of the OSS were grade 1, and the other screws were grade 0. The Matta scores of nine patients were excellent, and three patents were good.

CONCLUSION

OSS in the S1 combined with TTS in the S2 had the best mechanical stability in six models, and it is safe for screw insertion assisted by the patient-specific locked navigation template.

Current management and clinical outcomes for patients with haemorrhagic shock due to pelvic fracture in Korean regional trauma centres: A multi-institutional trial

INTRODUCTION

The purpose of this study was to evaluate the current management and clinical outcomes in patients with hemodynamic instability due to pelvic fracture in three regional trauma centres in Korea.

PATIENTS AND METHODS

Three regional trauma centres participated in this study, and 157 patients who were admitted between January 2015 and December 2018 were enroled. Clinical data were collected prospectively as part of the Korean trauma data bank and were analysed retrospectively.

RESULTS

The mean age was 59.3 years, and 107 of 157 (68.2%) were male patients. The most common cause of injury was auto-pedestrian accidents, followed by falls and motor vehicle crashes. The mean admission systolic blood pressure and serum lactate level were 86.7 mmHg and 6.68 mmol/L, respectively. Twenty-four patients (15.3%) had a cardiac arrest in the emergency department (ED). The mean injury severity score was 39.1, and the mean probability of survival (Trauma and Injury Severity Score) was 48.7%. Sixty-six patients (42%) underwent pelvic angiography; 89 (56.7%), preperitoneal pelvic packing (PPP); 27 (17.2%), resuscitative endovascular balloon occlusion of the aorta (REBOA); 20 (12.7%), pelvic external fixation (PEF); and 13 patients (8.3%), internal iliac artery ligation (IIAL). Seventy-three patients (46.5%) died, including 40 (25.5%) who died from acute haemorrhage. With each year, the rates of REBOA and pelvic binder use continued to increase (p<0.001 and p = 0.005, respectively), but the number of PEF cases significantly decreased (p = 0.006). Age, initial lactate, low revised trauma score (RTS), combined abdominal injury, REBOA, and 4-hour requirement of packed red blood cells were independent risk factors associated with mortality, whereas during the period of 2017 and 2018, there were protective factors. The risk factors of mortality due to haemorrhage were cardiac arrest in the ED, RTS, combined chest and abdominal injuries, and IIAL.

CONCLUSIONS

Since the establishment of regional trauma centres, the clinical outcomes of patients with hemodynamic instability due to pelvic fracture have significantly improved. As a haemostatic procedure for these patients, PEF has been used less frequently, while pelvic binder and REBOA showed significant increase in their use.
