Unilateral Traumatic Testicular Dislocation in a Patient of Pelvic Diastasis and Spine Fracture in an Adult: A Case Report and Review of Literature.

Introduction: With advancement, the occurrence of road traffic accidents is common. Timely management of fractures of the spine and pelvis is of the utmost importance for survival, ambulation, and maintenance of normal life. Genitourinary complications following pelvic ring injuries are not unknown; however, testicular dislocation is rare and can cause significant morbidity if not managed appropriately. Case Report: Our case was a 25-year-old male who was presented to the tertiary trauma center following a motorcycle accident. He had an anteroposterior compression (APC) fracture of the pelvic ring (APC-III, Arbeitsgemeinschaft für Osteosynthesefragen 61-C1.2), D8-D9 vertebra compression fracture, fracture of the left distal radius, and radio-carpal dislocation. However, no concomitant genitourinary injury was noticed at the initial assessment. After resuscitation, the pelvis was planned to be fixed with an anterior symphyseal plate and posterior sacroiliac joint fixation using 2 cancellous screws. While using Stoppa's approach, surprisingly, the right testicle was observed to be inferior to the pubis. Trauma surgery help was sought and the dislocated testis was reduced and managed with orchidopexy after checking the viability. At the follow-up of 1 year,the pelvic fracture was united without urogenital complication. Conclusion: In cases of complex pelvic ring injury, a careful genital examination should be performed and a multi-disciplinary team approach with compromising of radiology, traumatology, and orthopedics departments should be adopted for better patient outcomes.

Clinical and radiographic predictors for angiography in pelvic trauma: An analysis of 1703 patients.

INTRODUCTION: Patients who present with hemorrhage from pelvic fractures have an increased risk of mortality with prolonged time to intervention. Identifying risk factors associated with hemorrhage can expedite treatment. In this study we explore clinical and radiographic predictors for angiography in trauma patients with pelvic fractures. METHOD: Retrospective, single-center review between 2009 and 2019 at a level 1 trauma center of all trauma patients with pelvic fractures. We excluded patients who died prior to arrival or in the trauma bay who did not undergo computed tomography ("CT"). Finalized attending descriptions of CT findings were reviewed, including size of hematomas, and presence of extravasation. Chi-square, Mann-Whitney U and multi-variate regressions were performed. RESULTS: We analyzed 1,703 trauma patients with pelvic fractures. Most common mechanisms of injury included MVC (45 %), fall (27 %) and motorcycle accident (12 %). 48 % (819/1703) of patients had pelvic hematomas on CT scan. 17 %(138/819) of patients with a hematoma also had evidence of extravasation. Significant predictors for extravasation on CT included large hematoma on CT, AIS extremity ≥2, binder placement, increased ISS, HR, and decreased GCS and SBP (p < 0.005). Significant predictors for angiography were similar, including AIS extremity ≥2, binder placement, presence of moderate and large hematoma and active extravasation on CT (p < 0.01). Stepwise logistic regression model incorporated ISS, HR, AIS extremity score, binder placement, and contrast extravasation with an AUC = 0.9345. CONCLUSION: In this large retrospective review of traumatic pelvic fractures, specific clinical and radiographic factors were significantly associated with pelvic hematomas, extravasation and/or need for angiography. Future collaborative work with orthopedics and interventional radiology is planned to better triage pelvic fracture patients and identify those at risk for bleeding that require earlier intervention.

[Effectiveness of reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures].

Objective: To explore the effectiveness of reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures. Methods: Between January 2022 and February 2023, 10 patients with Tile type B pelvic fractures were admitted. There were 6 males and 4 females with an average age of 45.5 years (range, 30-71 years). The fractures were caused by traffic accident in 5 cases, bruising by heavy object in 3 cases, and falling from height in 2 cases. The interval between injury and operation ranged from 4-13 days (mean, 6.8 days). There were 2 cases of Tile type B1 fractures, 1 case of Tile type B2 fracture, and 7 cases of Tile type B3 fractures. After closed reduction under assistance of reduction robot, the anterior ring was fixed with percutaneous screws with or without internal fixator, and the posterior ring was fixed with sacroiliac joint screws under assistance of navigation robot. The time of fracture reduction assisted by the reduction robot was recorded and the quality of fracture reduction was evaluated according to the Matta scoring criteria. The operation time, intraoperative fluoroscopy frequency and time, intraoperative bleeding volume, and incidence of complications were also recorded. During follow-up, the X-ray film of pelvis was taken to review the fracture healing, and the Majeed score was used to evaluate hip joint function. Results: The time of fracture reduction was 42-62 minutes (mean, 52.3 minutes). The quality of fracture reduction according to the Matta scoring criteria was rated as excellent in 4 cases, good in 5 cases, and poor in 1 case, with excellent and good rate of 90%. The operation time was 180-235 minutes (mean, 215.5 minutes). Intraoperative fluoroscopy was performed 18-66 times (mean, 31.8 times). Intraoperative fluoroscopy time was 16-59 seconds (mean, 28.6 seconds). The intraoperative bleeding volume was 50-200 mL (range, 110.0 mL). No significant vascular or nerve injury occurred during operation. All patients were followed up 13-18 months (mean, 16 months). X-ray films showed that all fractures healed with the healing time of 11-14 weeks (mean, 12.3 weeks). One case of ectopic ossification occurred during follow-up. At last follow-up, the Majeed score was 70-92 (mean, 72.7), and the hip joint function was rated as excellent in 2 cases and good in 8 cases, with the excellent and good rate of 100%. Conclusion: The reduction robot combined with navigation robot-assisted minimally invasive treatment for Tile type B pelvic fractures has the characteristics of intelligence, high safety, convenient operation, and minimally invasive treatment, which can achieve reliable effectiveness.

The mode of delivery after operative fixation of pelvic ring fractures-a retrospective observational study.

PURPOSE: The purpose of this study is to investigate whether retained hardware after surgical treatment for a pelvic fracture prior to pregnancy affects the choice of delivery method. The study aims to provide insights into the rates of vaginal delivery and caesarean sections, understanding whether the mode of delivery was influenced by patient preference or the recommendations of obstetricians or surgeons, and examining the rate of complications during delivery and postpartum. METHODS: All women of childbearing age who underwent surgical fixation for a pelvic ring fracture between 1994 and 2021 were identified. A questionnaire was sent about their possible pregnancies and deliveries. Of the included patients, surgical data were collected and the fracture patterns were retrospectively classified. Follow-up was a minimum of 36 months. RESULTS: A total of 168 women with a pelvic fracture were identified, of whom 13 had a pregnancy after surgical stabilization. Eleven women had combined anterior and posterior fracture patterns and two had isolated sacral fractures. Four women underwent combined anterior and posterior fixation, the others either anterior or posterior fixation. Seven women had a total of 11 vaginal deliveries, and 6 women had 6 caesarean sections. The decision for vaginal delivery was often the wish of the mother (n = 4, 57%) while the decision to opt for caesarean section was made by the surgeon or obstetrician (n = 5, 83%). One woman in the vaginal delivery group suffered a postpartum complication possibly related to her retained pelvic hardware. CONCLUSION: Women with retained hardware after pelvic ring fixation can have successful vaginal deliveries. Complications during labor or postpartum are rare. The rate of primary caesarean sections is high (46%) and is probably influenced by physician bias. Future research should focus on tools that can predict labor outcomes in this specific population, and larger multicenter studies are needed. LEVEL OF EVIDENCE: Level III.

Transobturator-cable-fixation in pelvic ring injuries with symphyseal disruption - a last resort?

PURPOSE: The role of transobturator-cable-fixation (TOCF) in traumatic symphyseal rupture of the pelvic ring remains unclear. This case series aims to evaluate TOCF in complex and revision cases in pelvic surgery. METHODS: A retrospective analysis of a chronological case series was conducted, studying pelvic fractures stabilized using TOCF between January 2006 and December 2022. The variables considered included age, gender, fracture classification, Injury Severity Score (ISS), Body Mass Index (BMI), trauma mechanism, time to surgery, fixation technique, hospital duration, complications, status on discharge (Glasgow Outcome Scale; GOS), follow-up time and indication for the use of TOCF. RESULTS: All patients (N = 7) were male with a mean age of 64 years and a mean BMI of 29. The mean ISS was 45, with the lowest ISS of 25, indicating that only polytraumatized patients were included. Two anterior-posterior-compression-, four lateral-compression-, and one vertical-shear-pelvic-injury were identified. TOCF was added in six cases to support symphyseal plating and in one case to external fixation. The mean hospital stay was 49 days and the mean follow-up duration was 8.5 months. No complications associated with TOCF were observed during the surgical procedure or follow-up. CONCLUSION: TOCF showed no procedure-associated complications and effectively supported symphyseal healing in all cases. The main indications were obesity, poor bone quality in elderly patients, and revision cases. TOCF could be considered as a last treatment option in open-book pelvic injuries where plating or external fixation is at risk to fail.

[Pulsed thulium laser combined with pulsed thulium laser injection for the treatment of failed urethral anastomosis].

OBJECTIVE: To investigate the clinical effect of pulsed thulium laser (PTL) combined with triamcinolone acetonide injection in the treatment of failed posterior urethral anastomosis (FPUA). METHODS: This retrospective study included 35 male patients treated in Gongli Hospital for failed posterior urethral anastomosis from January 2018 to December 2023. All the patients underwent direct-vision internal urethrotomy (DVIU) with transurethral PTL (the PTL group, n = 15) or transurethral plasma (the TUP group, n = 20), and all received intralesional injection of triamcinolone acetonide. We followed up the patients for a median of 21 months, recorded the age, length of urethral stricture, operation time, pre- and post-operative maximum urinary flow rate (Qmax), postoperative complications and recurrence of urethral stricture, and compared the data obtained between the two groups. RESULTS: All the patients smoothly completed the treatment procedures. No statistically significant differences were observed in the age, length of urethral stricture, operation time and postoperative complications between the two groups (P > 0.05). The median follow-up time for the thulium laser group and plasma group was 21.0 months (IQR 16.0－24.0) and 21.0 months (IQR 17.0－25.0), respectively, with a statistically significant difference observed in the maximum urine flow rate before and after surgery at the 12-month mark (P < 0.01). No significant disparity was found in terms of relapse-free survival between the two groups (P = 0.398) Conclusion: Pulsed thulium laser combined with triamcinolone acetonide injection can effectively maintain a short-term cicatricial stability of the urethral stricture and satisfactory urethral patency, obviously superior to plasmotomy as a remedial treatment of urethral stricture after failed posterior urethral anastomosis.

[Research progress of pelvic acetabular fractures combined venous thromboembolic disease].

Pelvic acetabular fractures(PAFs) are one of the most common types of pelvic fractures, mostly high-energy injuries, with complex pelvic acetabular structure and limited surgical methods. The trauma of the acetabular fracture itself and the need for long-term bed rest after surgery cause particularly complicated clinical complications. Venous thromboembolism (VTE) is one of its high incidence and serious complications. This review mainly focuses on VTE after PAFs, and describes the epidemiology, risk factors and prevention measures of VTE, aiming to help improve the prognosis and avoid the occurrence of serious complications.

Trends and epidemiology of lower trunk fractures in the super elderly population in the United States from 2011 to 2020.

INTRODUCTION: Fractures of the lower trunk are among the most common fractures occurring in the elderly. Super elderly individuals (i.e., those 80 years of age and older) represent a growing segment of the population and are especially prone to these fractures. The contemporary epidemiology of lower trunk fractures in the super elderly population is incompletely described in the literature. MATERIALS AND METHODS: This descriptive epidemiology study used the National Electronic Injury Surveillance System (NEISS) to examine the incidence and recent trends of lower trunk fractures (i.e., fractures of the hip, pelvis, and lumbar spine) occurring among super elderly individuals in the United States (US) from 2011 to 2020. Annual, overall, and age-/sex-specific incidence rates (IRs) were analyzed. Average annual percent change (AAPC) estimates were calculated to indicate the magnitude/direction of trends in annual injury rates. RESULTS: An estimated N=1,226,160 super elderly patients sustained lower trunk fractures over the 10-year study period for an overall IR of 100.2 per 10,000 person-years at-risk (PYR). Hip fractures accounted for the largest percentage of cases (IR=71.7 PYR), followed by lumbar spine fractures (IR=14.7), and pelvic fractures (IR=14.3). The incidence of lower trunk fractures among super elderly females (IR=121.5 PYR) was significantly greater than that of males (IR=65.7 PYR). The incidence of lower trunk fractures among nonagenarians and centenarians was significantly higher than that of octogenarians. Accounting for population growth yielded a significantly increasing annual incidence of lower trunk fractures in super elderly patients over the study period from 86.7 PYR in 2011 to 107.2 PYR in 2020 (AAPC=2.7, p<0.001). The annual incidence of both pelvic (AAPC=5.8) and lumbar spine (AAPC=6.9) fractures increased at a significantly higher rate than that of hip fractures (AAPC=1.4). CONCLUSIONS: This study suggests that the annual incidence of lower trunk fractures in the oldest cohort of patients in the US (80+ years of age) increased significantly during the recent decade from 2011 to 2020, with pelvic and lumbar fractures in particular becoming increasingly common. Increased incidence rates highlight the need for future research aimed at optimizing outcomes and quality of life in this frail and ever-growing segment of the population.

Infected closed pelvic fractures in two adults - Case report.

INTRODUCTION: Infections following closed fractures in immunocompetent adults are rare but can have significant consequences if not promptly diagnosed. CASE PRESENTATION: We present two cases of immunocompetent adults admitted to a hospital in Tanzania with closed pelvic fractures who were found to have infections intraoperatively. Both patients responded well to treatment with one delaying to clear the infection. CLINICAL DISCUSSION: Because it rarely happens infected closed fractures are difficult to diagnose prior to surgery and treatment is controversial, most authors propose priority should be getting the fracture to unite then treatment of infection. CONCLUSION: This report adds to the existing literature on infections following closed fractures and highlights the importance of considering infection in closed fractures and tailoring management strategies to individual patient factors.

Pelvic ring fracture in the older adults after minor pelvic trauma - is it an innocent injury?

OBJECTIVE: This study aimed to evaluate the prevalence of severe hemorrhage as a potentially life-threatening complication in elderly patients with isolated, low-energy pelvic ring fractures, which may be more common than previously described. PATIENTS AND METHODS: A retrospective cohort study was conducted at an academic level 1 trauma center, including 579 patients aged over 65 who suffered from isolated low-energy pelvic fractures between 2006 and 2020. Pelvic computer tomography (CT) scans, with or without contrast, were performed and reviewed for patients with suspected posterior ring injury or bleeding. Patients without CT scans were excluded from the study. RESULTS: Among the 123 patients with isolated pubic rami fractures, 30 (24.4 %) had bleeding with a significant hemoglobin drop (>2 g%). 21(70 %) patients of these had posterior pelvic ring involvement as compared to 45 who did not bleed (51 %, p = 0.07). There was a significantly larger proportion of patient who received anticoagulant therapy (ACT) with posterior ring injury among the bleeding group (20 % vs 3.2 % p < 0.01). Treatment included blood transfusion (19/123, 15.5 %), and arterial angiographic embolization (5/123, 4 %). No complications related to angio-embolization were observed, and all patients survived the initial 90-day period. No other source of bleeding was identified in any of these patients. CONCLUSION: Severe pelvic hemorrhage in the older adults due to a minor pelvic injury after a low-energy trauma is not an uncommon complication, especially with combination of ACT and posterior pelvic ring fracture. This indicates that these injuries more challenging than previously believed. Geriatric pelvic ring injuries should be monitored carefully with serial blood counts, and low threshold for imaging including contrast enhanced CT scans and angiography.

Clinical frailty and short-term outcomes after low-energy pelvic fracture in the geriatric population: Nationwide inpatient sample 2016-2018 analysis.

BACKGROUND: Pelvic fractures can be life-threatening for elderly individuals with diminished bone strength. Frailty is associated with fracture outcomes, but its impact on pelvic fracture recovery remains unexplored. The aim of this study was to investigate the association between frailty and short-term outcomes in older adults hospitalized for low-energy pelvic fractures. METHODS: Data from the Nationwide Inpatient Sample (NIS) covering the years 2005 to 2018 were reviewed. Inclusion criteria were age ≥ 60 years admitted for a low-energy pelvic fracture. Patients were categorized into frail and non-frail groups using the 11-factor modified Frailty Index (mFI-11). Association between frailty and in-hospital outcomes were determined by univariate and multivariable regression analyses. RESULTS: A total of 24,688 patients with pelvic fractures were included. The mean patient age was 80.6 ± 0.1 years, and 35 % were classified as frail. After adjustments, frailty was significantly associated with unfavorable discharge (adjusted odds ratio [aOR] = 1.07, 95 % confidence interval [CI]: 1.00-1.15, p = 0.038), prolonged hospitalization (aOR = 1.51, 95 % CI: 1.41-1.62, p < 0.001), complications (aOR = 1.42, 95 % CI:1.34-1.50, p < 0.001), and acute kidney injury (aOR = 1.68, 95 % CI: 1.56-1.82, p < 0.001). Stratified analyses based on age and fracture type showed frailty was consistently associated with adverse outcomes. CONCLUSIONS: Persons ≥60 years old with mFI-11 assessed frailty and a low-energy pelvic fracture are at higher risk of adverse in-hospital outcomes than non-frail patients. Additional research is needed to disclose the prognostic impact of clinical frailty on long-term functional outcomes and quality of life after discharge.

Thirty-Day Surgical Morbidity and Mortality in Pelvic and Acetabular Fracture Patients Presenting to a Tertiary Care Hospital in Karachi, Pakistan.

INTRODUCTION: Pelvic fractures, encompassing a spectrum from minor to life-threatening injuries, pose challenges in trauma management. This study focuses on short-term outcomes, exploring morbidity and mortality within 30 days postoperative, among pelvic fracture patients at a tertiary care hospital in Karachi, Pakistan. The majority of pelvic injuries result from intense blunt trauma, with associated risks of concomitant injuries. Pelvic fractures are linked to early complications such as hemorrhage, thromboembolism, and infections, influencing mortality rates. METHODOLOGY: A prospective cohort study involving 53 surgically managed pelvic fracture patients was conducted at Aga Khan University Hospital, Karachi. Variables such as age, gender, comorbidities, mechanism of injury, associated injuries, and presenting vitals were documented. Thirty-day morbidity included surgical site infections, hemorrhagic shock, nerve injuries, and others. Statistical analyses assessed associations between patient characteristics and morbidity. RESULTS: The study revealed a median age of 37 years, with 77% male patients. Most fractures result from motor vehicle accidents. Morbidity occurred in 31.6% of cases, primarily associated with the presence of associated injuries. Postoperative complications included neurological deficits (15.1%) and pulmonary complications (9.4%). No 30-day mortality was reported. DISCUSSION: The study highlights the importance of a multidisciplinary approach in managing pelvic fractures, emphasizing the association between associated injuries and postoperative morbidity. Comorbidities did not significantly impact morbidity, emphasizing the traumatic nature's independent contribution. Timely presentation (median 20 hours) and efficient trauma systems are crucial for optimal outcomes. CONCLUSION: This research contributes insights into short-term outcomes following pelvic fracture fixation in a Pakistani tertiary care setting. By exploring a range of parameters, the study emphasizes the need for comprehensive management strategies to minimize complications and improve patient outcomes. Bridging critical knowledge gaps, this research informs clinical decision-making for pelvic fracture patients in this region.

Lower abdominal cyst complicated with suspected infection following INFIX internal fixation for pelvic fracture: a report of two rare cases.

BACKGROUND: The Internal Fixator (INFIX) is a popular method, known for its minimal invasiveness and short operation time, for treating anterior pelvic ring fractures. Studies have shown that postoperative complications may occur, including anterolateral femoral cutaneous nerve injury, the femoral nerve paralysis, and delayed fracture healing. These complications are believed to be related to surgical stimulation, an excessively long lateral end of the connecting rod, a small distance between the screw and bone surface, insufficient pre-bending of the connecting rod, and difficulties in fracture reduction. CASE PRESENTATION: We report two unique cases of lower abdominal pseudocyst complicated with suspected infection after INFIX treatment of pelvic fractures at our trauma center. Following surgical removal of the internal fixation, resolution of the cysts was observed in both patients, and subsequent postoperative follow-up revealed the absence of any residual sequelae. These cases have not been reported in previous literature reviews. DISCUSSION: The lower abdominal cysts, potentially arising from the dead space created during intraoperative placement of the INFIX rod, may increase infection risk. The etiology remains uncertain, despite the presence of abnormal inflammation markers in both cases, and staphylococcus aureus found in one. These cysts were confined to the lower abdomen, not involving the internal fixation, and hence, only the INFIX was removed. Postoperative oral cefazolin treatment was successful, with resolved pseudocysts and no subsequent discomfort. CONCLUSION: We report two unprecedented cases of post-INFIX abdominal cysts, with a suspected link to intraoperative dead space. Despite uncertain etiology, successful management involved INFIX removal and oral cefixime therapy. These findings necessitate further exploration into the causes and management of such complications.

A new technique for percutaneous screw fixation for treating FFP IIIa and IIIb fragility fractures of the pelvis.

To determine the presence of a consistent osseous corridor from the lateral-posterior aspect of the anterior inferior iliac spine to the sacral wing that could be used for safe trans percutaneous screw fixation for pelvic fragility fractures of the iliac wing and fracture dislocations of the sacroiliac joint (FFP types IIIa and IIIb). Computed tomography (CT) scans were obtained from 100 patients and imported to Mimics software for 3D reconstruction. Then, a cylinder was drawn to imitate the modified LC-II screw and adjusted to a maximum radius and length to obtain the feasible region. Thirteen parameters of the osseous corridor of the modified LC-II screw were measured. Differences between sex groups were compared, and significant statistical correlations were carefully studied to determine potentially important clinical relationships. The records of patients with FFP type IIIa and IIIb fragility fractures of the pelvis were extracted from our hospital. Patients who underwent modified LC-II screw fixation, LC-II screw fixation or reconstruction plate fixation were included. Patients' operative characteristics and complications were recorded at follow-up. Fracture reduction quality was assessed using the Matta standard. Functional outcomes were evaluated using the Majeed grading system. The mean maximum diameters of the osseous corridors of the modified LC-II screw in males and females were 12.73 and 10.83 mm, respectively. The mean maximum lengths of the osseous corridors of the modified LC-II screw in males and females were 96.37 and 93.37 mm, respectively. In the treatment of patients with FFP IIIa and FFP IIIb fractures, the group of treatment by the modified LC-II screws fixation was shown significantly shorter operative time and fewer intraoperative blood loss in comparison to that by the reconstruction plates. In the present study, all the males and females had a complete osseous corridor of the modified LC-II screw. The clinical results of the patients who were treated with modified LC-II screw fixation suggest that the novel method has a good preliminary outcome.

Management of long-term functional sequelae of pelvic fracture urethral injury.

Pelvic fracture (PF) is a rare emergency, which led to pelvic fracture urethral injury (PFUI) in 1.6% to 25% of cases. Urethral injury assessment requires a thorough analysis of the initial injury history and imaging that combine cystourethrography acutely, repeat urethral imaging as well as adjunctive use of MRI in the follow-up period. A more complex surgical approach to the delayed reconstruction of PFUI may be predicted by the urethral gap length (cysto-urethrography) or a lower pubo-urethral angle (MRI). Delayed urethroplasty is the treatment of choice, performed once the patient has recovered from other acute injuries, typically at least 3months post-injury. It consists in men in a bulbo-prostatic anastomotic urethroplasty which may require several steps of increasing complexity to allow a tension-free anastomosis: corpora splitting, partial inferior pubectomy, and rarely total pubectomy or urethra rerouting. More complex cases of PFUI repair may be encountered (long gap between the two urethral segments, bulbar necrosis, false passage after failed endoscopic realignment, orthopedic hardware in pubic symphyseal region, pediatric PFUI, failed previous urethroplasty, associated anterior urethral stricture, or recto-urethral fistula) and should be managed in expert centers. Urethral patency is achieved by surgical reconstruction with an overall success rate of 86%. Evaluation of potential associated sequelae including erectile dysfunction and urinary incontinence must be anticipated and taken into consideration in the path of rehabilitation.

Internal iliac artery ligation as a damage control method in hemodynamically unstable pelvic fractures: A systematic review of the literature.

PURPOSE: Internal iliac artery ligation (IIAL) has been used as a damage control procedure to treat hemodynamically unstable pelvic fracture for many years. However, there is ongoing debate regarding the effectiveness and safety of this hemostatic method. Therefore, we performed a systematic literature review to assess the efficacy and safety of IIAL for pelvic fracture hemostasis. METHODS: Three major databases, PubMed, Embase, and Google Scholar, were searched to screen eligible original studies published in English journals. Two reviewers independently read the titles, abstracts, and full texts of all literature. Articles were included if they reported the use and effects of IIAL. RESULTS: A total of 171 articles were initially identified, with 22 fully meeting the inclusion criteria. Among the analyzed cases, up to 66.7% of patients had associated abdominal and pelvic organ injuries, with the urethra being the most frequently injured organ, followed by the bowel. The outcomes of IIAL for achieving hemostasis in pelvic fractures were found to be satisfactory, with an effective rate of 80%. Hemorrhagic shock was the leading cause of death, followed by craniocerebral injury. Notably, no reports of ischemic complications involving the pelvic organs due to IIAL were found. CONCLUSION: IIAL has a good effect in treating hemodynamically unstable pelvic fracture without the risk of pelvic organ ischemia. This procedure should be considered a priority for hemodynamically unstable pelvic fracture patients with abdominal organ injuries.

A bidirectional framework for fracture simulation and deformation-based restoration prediction in pelvic fracture surgical planning.

Pelvic fracture is a severe trauma with life-threatening implications. Surgical reduction is essential for restoring the anatomical structure and functional integrity of the pelvis, requiring accurate preoperative planning. However, the complexity of pelvic fractures and limited data availability necessitate labor-intensive manual corrections in a clinical setting. We describe in this paper a novel bidirectional framework for automatic pelvic fracture surgical planning based on fracture simulation and structure restoration. Our fracture simulation method accounts for patient-specific pelvic structures, bone density information, and the randomness of fractures, enabling the generation of various types of fracture cases from healthy pelvises. Based on these features and on adversarial learning, we develop a novel structure restoration network to predict the deformation mapping in CT images before and after a fracture for the precise structural reconstruction of any fracture. Furthermore, a self-supervised strategy based on pelvic anatomical symmetry priors is developed to optimize the details of the restored pelvic structure. Finally, the restored pelvis is used as a template to generate a surgical reduction plan in which the fragments are repositioned in an efficient jigsaw puzzle registration manner. Extensive experiments on simulated and clinical datasets, including scans with metal artifacts, show that our method achieves good accuracy and robustness: a mean SSIM of 90.7% for restorations, with translational errors of 2.88 mm and rotational errors of 3.18°for reductions in real datasets. Our method takes 52.9 s to complete the surgical planning in the phantom study, representing a significant acceleration compared to standard clinical workflows. Our method may facilitate effective surgical planning for pelvic fractures tailored to individual patients in clinical settings.

Trauma team activation for older patients with pelvic fractures: Are current criteria adequate?

OBJECTIVES: The present study aimed to identify the impact of age on current trauma team activation (TTA) processes and outcomes for patients with pelvic fractures. METHODS: Adult patients with moderate and/or severe pelvic fractures (Abbreviated Injury Scale ≥ 2) between 1 January 2016 and 31 December 2021 were included utilising major trauma hospital data in Queensland. Characteristics of older (age ≥ 65) and younger patients including TTA, interventions and outcomes were examined. Multivariate analysis was used to determine factors associated with TTA in older patients. RESULTS: Data from 637 patients was included. Despite comparable injury severity, a TTA was activated in fewer older people (older: 65% vs. younger: 79%, P < 0.001). Older patients had more falls leading to the trauma presentation (54.4% vs. 22.6%, P < 0.001), with higher initial systolic BP (131 vs. 125 mmHg, P = 0.04). Outcomes were worse for older people, with greater rates of in-hospital complications (27.2% vs. 16.4%, P = 0.004), and longer hospital stays (12 vs. 8 days, P = 0.04). Fewer older patients could be discharged independently to home (46.3% vs. 74.5%, P < 0.001). In older patients, falls and haemodynamic parameters were strongly associated with the reduced likelihood of TTA (fall mechanism [odds ratio (OR)] 0.33; 95% confidence interval [CI] 0.15-0.74; P = 0.01; systolic BP [OR 0.98; 95% CI 0.97-0.99; P = 0.03], heart rate [OR 0.97; 95% CI 0.95-0.99; P = 0.02]). CONCLUSION: Current TTA criteria based on higher energy mechanisms and traditional vital sign thresholds are inadequate for identifying injury in older patients. Sensitive triage criteria and increased clinician awareness are required to enhance injury recognition and improve outcomes in older trauma patients.

Traumatic pelvic fracture with rupture of the ovarian vein - A case report.

INTRODUCTION AND IMPORTANCE: Traumatic pelvic fractures are complex injuries often associated with significant morbidity and mortality. Among the complications of pelvic trauma, rupture of the ovarian vein represents a rare yet potentially life-threatening event. Prompt recognition and appropriate management are essential to mitigate the risk of hemorrhage and associated complications. CASE PRESENTATION: We present a case of a 70-year-old woman who sustained a traumatic pelvic fracture following a skiing accident, resulting in rupture of the left ovarian vein. The patient came with the ambulance in the emergency room with lower abdominal tenderness, pelvic pain, but no signs of hemorrhagic shock. Imaging studies confirmed the diagnosis of a pelvic fracture with venous leakage of the left ovarian vein. CLINICAL DISCUSSION: This review synthesizes recent insights into the diagnosis, management, and complications associated with pelvic fractures, with an emphasis on optimizing patient outcomes through a multidisciplinary approach. The analysis incorporates findings from key studies, including those by Wong and Bucknill, Ma Y et al., and Tullington and Blecker, which advocate for the use of advanced diagnostic tools like CT scans and systematic evaluation processes. These studies underline the necessity of precise classification systems such as the Tile classification to guide treatment and predict outcomes. CONCLUSION: Management of traumatic pelvic fractures with associated vascular injuries requires a multidisciplinary approach involving trauma surgeons, interventional radiologists, and critical care specialists. Early recognition, accurate diagnosis, and timely intervention are paramount in optimizing outcomes and reducing the risk of mortality. This case underscores the importance of prompt intervention and highlights the challenges associated with traumatic pelvic fractures and rupture of the ovarian vein. Further research is warranted to enhance our understanding of optimal management strategies and improve outcomes for patients with these complex injuries.

Spring coil displacement after interventional embolization of severe pelvic fracture: a case report.

Haemorrhagic shock, which arises as a complication of pelvic fracture subsequent to severe trauma, represents a perilous state. The utilization of interventional endovascular haemostasis assumes a pivotal role in the management of patients with vascular injury following pelvic fracture. This article reports the treatment of a patient with pelvic fracture caused by a serious work-related vehicle accident. Despite the implementation of timely blood and fluid transfusion to combat shock, the application of aortic balloon obstruction, and interventional iliac artery embolization for haemostasis, the patient's condition failed to display any discernible improvement. Repeat angiography further revealed a displacement of the interventional embolization material, and the patient subsequently died of multiple organ failure. The occurrence of spring coil displacement is infrequent, but the consequences thereof are considered grave, necessitating meticulous discernment in the selection of haemostatic materials for this type of patient. The diagnostic and therapeutic processes encompassing the particular case described here were analysed and are discussed with the objective of augmenting the efficacy and success rate of treatment modalities for patients in similar circumstances.
