EP241 - Managing Cervical Spine fracture in a district general hospital

Abstract Introduction Cervical spinal injury affects 2–3% of trauma patients and accounts for 8.2% of all trauma-related deaths. Respiratory complications are cited as the primary cause of mortality with a 14 - >27 % rate in patients aged more than 65 years old. Aim Produce a clear set of guidelines in an aim to reduce mortality in patients > 65 years presenting with cervical spine fracture. Method Data was retrospectively collected for patients aged >65 between September 2021 and August 2022 in a district general hospital. Patients with confirmed cervical spine injury were included in the study. Data was collated and analysed using Excel. Results 36 patients presented to ED with acute cervical spine fracture. 22 (61%) were female and 14 (39%) male with an age range of 66-98 years old. 31 (84%) patients were discussed with a tertiary centre. Complications ranged from constipation, delirium, DVT/PE, chest infections (n=5, 36%) to spinal shock (n= 3, 27%). 11 (30.6%) patients presenting with a c-spine fracture died within 30 days of admission.9 (25%) patients had an outpatient appointment booked in a tertiary centre and 13 (36%) were seen locally in the fracture clinic. 14 (39%) patients did not have any follow ups planned. Conclusions To mitigate in-hospital complications and improve outcomes, shared care with orthopaedics, geriatrics, and physiotherapy is being proposed for this group of patients. It would be beneficial to compare the data from the local network and aim at publishing an up-to-date set of robust guidelines.

Postoperative ileus in obstetric and gynecological practice: a prospective solution to the problem

Proton pump inhibitors (PPIs) are the undisputed leaders in the treatment of acid-related diseases. In actual clinical practice, the use of PPIs has been growing exponentially in recent decades. For a long time, PPIs were considered completely safe drugs for both short-term and long-term use. However, modern clinical guidelines and reviews and meta-analyses of the current decade on the safety of PPI use note that when prescribing PPIs in large doses for a long period, the possibility of developing numerous side effects should be taken into account. We searched the PubMed and Scopus information databases for publications on the safety of PPI use, including sources up to 12/01/2023. The review addresses issues of drug interactions between PPIs and chemotherapeutic drugs, which should certainly be taken into account in real clinical practice. In addition, recent reviews and meta-analyses have examined side effects of long-term PPI use, such as increased risk of infection (Clostridium difficile infection, community-acquired pneumonia), electrolyte disturbances, kidney damage, increased risk of hip, wrist and spine fractures; increased cardiovascular risk and a number of others, which can also have an adverse effect on the prognosis of cancer patients. The risk of developing gastric cancer with long-term PPI therapy can be considered as a likely side effect, since their association with PPI use is not denied or questioned in recent reviews and meta-analyses. There is still uncertainty regarding the increased risk of other cancers, since there are publications that do not confirm their association with PPI use. However, the presented review, despite a number of contradictions, allows us to conclude that the increased cancer risk with long-term use of PPIs is real and must be taken into account when prescribing PPIs for a long term.

Clinical application of a modified wiltse approach in middle and lower thoracic vertebrae: a case-control study of thoracic fracture patients

BackgroundThe Wiltse approach has been extensively employed in thoracolumbar surgeries due to its minimal muscle damage. However, in the middle and lower thoracic spine, the conventional Wiltse approach necessitates the severance of the latissimus dorsi and trapezius muscles, potentially leading to muscular injury. Consequently, we propose a modified Wiltse approach for the middle and lower thoracic vertebrae, which may further mitigate muscular damage.MethodsFrom May 2018 to April 2022, 60 patients with spinal fractures in the middle and lower thoracic vertebrae (T5-12) were enrolled in this study. Thirty patients underwent surgery using the modified Wiltse approach (Group A), while the remaining 30 patients received traditional posterior surgery (Group B). The observation indices included operation time, intraoperative blood loss, incision length, number of C-arm exposures, postoperative drainage, postoperative ambulation time, discharge time, as well as preoperative and postoperative Cobb’s angle, percentage of anterior vertebral body height (PAVBH), visual analog scale (VAS) Score, and Oswestry disability index (ODI).ResultsCompared to the traditional posterior approach, the modified Wiltse approach demonstrated significant advantages in operation time, intraoperative blood loss, length of incision, postoperative ambulation time, postoperative drainage, and discharge time, as well as postoperative VAS and ODI scores. No significant differences were observed between the two groups in terms of number of C-arm exposures, postoperative Cobb’s angle, or postoperative PAVBH.ConclusionWe propose a modification of the Wiltse approach for the middle and lower thoracic vertebral regions, which may further minimize muscular damage and facilitate the recovery of patients who have undergone surgery in the middle and lower thoracic vertebrae.

The epidemiology of recreation-related cervical and thoracic fractures

CONTEXTRecreational activities are frequently associated with spinal fracture, yet contemporary characterization of sports-related cervical and thoracic fracture is lacking. PURPOSETo characterize cervical and thoracic fractures associated with recreational activities. STUDY DESIGN/SETTINGRetrospective cohort study. PATIENT SAMPLEThe National Electronic Injury Surveillance System (NEISS) database OUTCOME MEASURE AND COMPARISONSRecreation-related cervical and thoracic fracture incidence rates per year, stratified by age and sex. Common causative activities were established by demographics. METHODSThe NEISS database was queried to identify patients with recreation-related cervical fractures between 2003 and 2022 and recreation-related thoracic fractures between 2003 and 2022 in patients aged >2 years-old. United States Census data was utilized to generate incidence rates per year. Data was stratified by demographic variables to assess the impact of age and sex on incidence and causative activity. RESULTSBetween 2003 and 2022, an estimated 13,823 recreation-related cervical fractures occurred with an average annual incidence of 2.20±0.35 per 1 million person-years, while 24,236 estimated recreation-related thoracic fractures occurred from 2003 to 2022 with an average incidence of 3.85±1.26. Males experienced a 3.51 times higher (95% CI 3.38–3.66) rate of cervical fracture, but thoracic fracture rates were similar between sexes. Individuals under 18 experienced a 2.15 times higher rate of thoracic fractures than those aged 18–64 (95% CI 1.85–2.50) and 1.93 times higher rate than those over 65 (95% CI 1.68–2.22). Recreation-related cervical fracture rates in individuals 18–64 was 1.186 (95% CI 1.14–1.23) times higher than those under 18 and rates in those under 18 were 1.15 (95% CI 1.09–1.22) times higher than those over 65. Football (26.6%), horseback riding (19.7%), and skiing (8.35%) were the primary causes of cervical fractures, and horseback riding (46.8%), football (11.2%), and skiing (10.3%) primarily caused thoracic fractures. Cervical fractures resulted primarily from football in males (24.7%) and horseback riding in females (44.0%). Horseback riding primarily caused thoracic fractures in both sexes (males=21.5%, females=74.7%). Football led causative activities for individuals under 18 (Cervical=42.4%, Thoracic=40.7%), while horseback riding dominated among those aged 18–64 (26.7%, 56.7%) and over 65 (52.8%, 67.9%). CONCLUSIONSThis investigation revealed epidemiological trends in cervical and thoracic spinal fractures and underscore the need for targeted preventive measures and safety interventions to mitigate the burden of these fractures particularly in horseback riding and American football.

Risk Factors for Nonunion After Nonoperative Treatment for Pediatric Lumbar Spondylolysis: A Retrospective Case-Control Study

Background: Pediatric lumbar spondylolysis, a stress fracture of the lumbar spine, frequently affects young athletes, and nonoperative treatment is often the first choice of management. Because the union rate in lumbar spondylolysis is lower than that in general fatigue fractures, identifying risk factors for nonunion is essential for optimizing treatment. Purpose: To determine the risk factors for nonunion after nonoperative treatment of acute pediatric lumbar spondylolysis through multivariate analysis. Study Design: Case-control study; Level of evidence, 3. Methods: We analyzed 574 pediatric patients (mean age, 14.3 ± 1.9 years) with lumbar spondylolysis who underwent nonoperative treatment between 2015 and 2022. Nonoperative treatment included the elimination of sports activities, bracing, and weekly athletic rehabilitation, with follow-up computed tomography. Patient data, lesion characteristics, sports history, presence of spina bifida occulta at the lamina with a lesion or at the lumbosacral spine excluding the lesion level, and lumbosacral parameters were examined. Differences between the union and nonunion groups were investigated using multivariate analysis to determine the risk factors for nonunion. Results: Of the 574 patients, 81.7% achieved bone union. Multivariate analysis revealed that an L5 lesion and the progression of the main and contralateral lesion stages were significant independent risk factors for nonunion. An L5 lesion had a lower union rate than non-L5 lesions. As the main lesion progressed, the likelihood of nonunion increased significantly, and the progression of the contralateral lesion also showed a similar trend. Spina bifida occulta and lumbosacral parameters were not significant predictors of nonunion in this study. Conclusion: We identified the L5 lesion level and the progression of the main and contralateral lesion stages as independent risk factors for nonunion in pediatric lumbar spondylolysis after nonoperative treatment. These findings aid in treatment decision-making. When bone union cannot be expected with nonoperative treatment, symptomatic treatment is required without prolonged external fixation and rest, and without aiming for bone union. Individualized treatment plans are crucial based on identified risk factors.

Mortality risk factors for adult trauma patients treated with halo brace for cervical spine fracture

Introduction and objectivesHalo braces treat upper cervical spine fractures and serve as the most rigid form of external immobilization. Recently, halo braces have lost favor due to known complications and advances in surgical stabilization. This study aims to determine the contemporary incidence for use of halo braces and identify risk factors associated with mortality in trauma patients undergoing halo brace for cervical spine fractures. Materials and methodsThe 2017–2019 Trauma Quality Improvement Program Database was queried for patients ≥18 years-old with a cervical spine fracture undergoing halo brace. Patients sustaining penetrating trauma and severe torso injuries (abbreviated injury scale >3 for the abdomen or thorax) were excluded. Bivariate and multivariable logistic regression analyses were performed. ResultsFrom 144,434 patients with a cervical spine fracture, 272 (0.2%) underwent halo brace and 14 (5%) of these died. Those who died were older (73.5 vs. 53 years-old, p = 0.011) and had higher rates of hypertension (78.6% vs 33.1%, p < 0.001) and chronic kidney disease (14.3% vs. 1.2%, p < 0.001). Glasgow Coma Scale ≤8 (46.2% vs. 8.2%, p < 0.001) and cervical spinal cord injury (71.4% vs. 21.3%, p < 0.001) were more common in patients who died. In addition, those who died more often sustained respiratory complications (7.1% vs. 0.4%, p = 0.004) and sepsis (7.1% vs. 0.4%, p = 0.004). On multivariable logistic regression analysis, only Glasgow Coma Scale ≤8 (OR 19.77, 3.04–128.45, p = 0.002) was associated with increased mortality. ConclusionsOnly 5% of cervical spine fracture patients undergoing halo brace died. Respiratory complications and sepsis were more common in those who died. On multivariable analysis only Glasgow Coma Scale ≤8 remained an independent associated risk factor for mortality.

To Manipulate or Not? Management of Pediatric Knee Arthrofibrosis Following Operative Fixation of Tibial Spine Fractures

ObjectivesKnee arthrofibrosis is a common complication after surgical fixation of tibial spine fractures. However, there is no standardized treatment modality for resultant arthrofibrosis, with some surgeons electing for non-operative management, while others prefer manipulation under anesthesia with a possible arthroscopic lysis of adhesions, if indicated. To better understand indications and outcomes from these treatment modalities for arthrofibrosis, we examined patients treated by both approaches. MethodsWe performed a multicenter retrospective case series of patients with arthrofibrosis after tibial spine fracture surgery. Arthrofibrosis was defined as loss of knee extension ≥ 10.0° and/or knee flexion ≥ 25.0° compared to the contralateral, uninjured knee at three months following index surgery. Patients were organized into two cohorts: non-operative and operative treatment. Data was collected for demographics, fracture classification, concomitant injuries, treatment timeline, and knee range of motion. ResultsThere were 16 patients in the operative group and 10 patients in the non-operative group. At the time of diagnosis, the operative group had a mean 10° larger flexion deficit compared to the non-operative group. Both treatment modalities resulted in similar ranges of motion at terminal evaluation. Final flexion was recorded as 130° in the operative group and 127° in the non-operative group. Final extension deficits were 3° in both cohorts. ConclusionsOperative and non-operative treatment modalities can be effective in management of knee arthrofibrosis after fixation of tibial spine fractures. Non-operative treatment may be more suitable for milder range of motion deficits, but further research is necessary to guide clinical practice. Level of EvidenceLevel IV, Case Series;

Observational Study of the Clinical Impact of E-scooter Injuries at a Major Trauma Centre.

Background Due to the increased use of e-scooters in the UK, associated injuries have increased, and its cost has increased as well. Worldwide data on injuries related to e-scooter use are relatively limited, owing to the short duration since their first introduction to the public. Aim There has been an increase in using e-scooters as a method of transport recently. It was noticed that the severity and frequency of its injuries are increasing as well. This study focuses on the frequency of e-scooter-associated injuries, especially open fractures, and to evaluate its burden on the health system. Methods Data on e-scooter injuries were extracted from our trauma database from November 2017 to July 2022. Patients' notes and images were reviewed. Outcome measures were the type of injuries: site of bony fractures, closed vs. open fracture (using Anderson and Gustilo classification), number of operations, complications, and length of hospital stay. Results The number of patients enrolled was 104. The mean age was 34.3 years, and 78.8% (n = 82) were male. The main mechanism of injury was riding (91%, n = 95) vs. hitting by an e-scooter (9%, n = 9). Injured patients were more likely not to wear helmets (82% of total injured patients). Patients with bony injuries were 65.4% (n = 68), with 22.1% (n = 15) of them being open fractures. The most common bony injuries were lower limb-only fractures at 45.6% (n = 31), then upper limb-only injuries at 39.7% (n = 27). Combined upper and lower limb cases were 8.8% (n = 6), and pelvic injuries were 5.9% (n = 4). Head and neck injuries composed 23.1% (n = 24) of the reported injuries, including intracranial haemorrhages (9.6%, n = 10), extensive traumatic brain injury (3.8%, n = 4), haematoma/lacerations (3.8%, n = 4), cervical spine fractures (1.9%, n = 2), and skull fractures (1.9%, n = 2). The mean duration of hospital stay was 8.6 days, and 9.6% (n = 10) of patients needed intensive therapy unit(ITU) admission. The number of patients presented as trauma calls was 55.8% (n = 58). Patients who needed surgical intervention either under orthopaedics or other specialties were 52.9% (n = 55) and 21.2% (n = 22) of total patients had complications either due to surgical intervention or a long hospital stay. Conclusion E-scooter riding can lead to serious injuries that can end with limb- or life-threatening conditions. The most common demographic characteristics were adults in their early 30s. There should be more emphasis on wearing protective gear like wrist and elbow guards in addition to helmets. Future prospective studies with larger cohorts across multiple regions and hospitals are necessary to truly characterize the nature and cost of e-scooter injuries.

Diagnosis and Treatment of Cervical Spine Fractures in Children

Background. Cervical spine injuries in children are relatively uncommon and account for approximately 1.5% of trauma admissions. The aim of our study was to determine the incidence and patterns of pediatric cervical spine fractures in a single Trauma Center over the last decade.Material and methods. The hospital’s medical database was queried for data from the period between January 2014 and December 2023. An initial search revealed that 511 patients had been hospitalized with neck injuries in that time frame. Among these records, we identified 24 patients with a fracture of the cervical spine. The inclusion criteria were: (1) age under 18 yo, (2) fracture of the cervical spine (3) follow-up of at least 6 months. A thorough analysis was performed, including injury mechanism, diagnosis, medical procedures and final outcome., A Neck Disability Index (NDI) was assessed for all patients at the six months’ follow-up visit to evaluate treatment outcomes.Results. The study group consisted of 14 boys and 10 girls aged 4.6 to 18 years (average age 14.2). We diagnosed one case of an isolated C1 fracture, six C2 fractures, two C4 fractures, two C5 fractures, two C7 fractures, and nine cases of multiple spinal fractures. Additionally, we diagnosed two cases of cervical spine dislocation: one of right-sided rotational dislocation of C6/C7 and one of complete dislocation of C2/C3. Eight patients were treated surgically by open reduction combined with anterior plate fixation. Four patients were treated using a halo vest. Eleven patients were treated conservatively: six using a Minerva orthosis, four with a cervical-thoracic orthosis, and one with a rigid cervical collar. The highest NDI values were encountered in the group of patients with concomitant intracerebral injury, where the mean value was 18.6/45 (12-26/45). The mean NDI score for the remaining patients was 4/45 (0 - 9/45).Conclusions. 1. The incidence of cervical spine fractures in children is low. 2. Most cervical spine injuries in children are treated conservatively with good outcomes. 3. Both conservative and surgical treatment of cervical spine fractures in children produces good results 4. Computed Tomography remains the gold standard for diagnosing cervical spine fractures in children. 5. The halo-vest in pediatric patients suffering from C2 fractures was well tolerated and provided good outcomes. 6. Surgical treatment of lower cervical fractures by open reduction with anterior fusion is efficient in terms of fusion status and patient satisfaction. 7. Prospective, randomized, multicenter studies are required to assess the epidemiology, methodology, and treatment effects of cervical spine fractures in children.

The Effect of Salmon Calcitonin Adjuvant Treatment for Lumbar Spine Fracture: A Prospective, Randomized, Controlled Trial.

The study aimed at analyzing the therapeutic effect of salmon calcitonin on patients with lumbar spine fracture after operation. Eighty-eight cases with lumbar spine fracture who underwent percutaneous vertebroplasty (PVP) in The Huichang People's Hospital from February 2020 to February 2023 were separated into two groups. The 44 cases in the control group were treated with calcium carbonate and Vitamin D3 tablets, on the basis, the salmon calcitonin was applied to treat the 44 cases in study group. The pain degree, bone metabolism index and matrix metalloproteinase levels were determined and compared between two groups. Lumbar function and daily living activity ability in two groups were evaluated, and adverse reactions during treatment were observed. The pain degree in study group was alleviated after treatment for 3 mo compared with the control group (p<0.05). The bone specific alkaline phosphatase (BALP) and osteocalcin (OC) levels were increased, while beta C-terminal cross-linked telopeptides of type I collagen (β-CTX) levels were decreased in study group after treatment for 3 mo compared with control group (p<0.05). After treatment for 3 mo, the serum matrix metalloproteinase-3 (MMP-3) and matrix metalloproteinase-9 (MMP-9) levels in study group were lower than those in control group (p<0.05). Three months after treatment, the Oswestry Disability Index (ODI) score was lower and Barthel Index (BI) score was higher in study group than those of control group (p<0.05). No severe adverse reactions were observed in both groups during treatment (p>0.05). Salmon calcitonin can relieve the pain degree, improve the levels of bone metabolism and matrix metalloproteinase, and improve the lumbar spine function and ability of daily living activity in patients with lumbar spine fracture.

Fear of Childbirth After Major Orthopedic Traumas: A Nationwide Multi-Register Analysis.

The aim of this study was to evaluate the association between previous major traumas and the prevalence of fear of childbirth (FOC) and the subsequent effects of FOC on the intended mode of delivery. In this nationwide retrospective register-based cohort study, data from the Care Register for Health Care were linked with the National Medical Birth Register (MBR) to evaluate the prevalence of FOC after major traumas. A total of 18,573 pregnancies met the inclusion criteria. A multivariable logistic regression model was used to assess the effects of FOC on the intended mode of delivery. Women with major traumas before pregnancy were compared to individuals with wrist fractures. Adjusted odds ratios (aORs) with 95% CIs between the groups were compared. Of those pregnancies that occurred after major traumas, 785 (6.2%) women were diagnosed with FOC after traumatic brain injury (TBI), 111 (6.1%) women after spine fracture, 38 (5.0%) women after pelvic fracture, 22 (3.2%) women after hip or thigh fracture, and 399 (5.2%) women in the control group. Among those women diagnosed with FOC, the adjusted odds for elective CB as an intended mode of delivery were highest among women with previous spine fractures (aOR 2.28, CI 1.45-3.60) when compared to the control group. We found no evidence of differences in maternal FOC in patients with preceding major traumas when compared to the control group. Therefore, it seems highly likely that the major trauma itself is the explanatory factor for the increased rate of elective CB.

Satisfactory 2-year outcome of minimal invasive hybrid stabilization with double treated screws for unstable osteoporotic spinal fractures.

This study evaluates whether the fracture level alters the outcomes of minimally invasive hybrid stabilization (MIHS) with double-threaded, uncemented polyaxial screws for unstable osteoporotic vertebral fractures. This prospective cohort study included 73 patients (71.23% females, mean age: 79.9 ± 8.8 years) with unstable OF 3-4 fractures treated by MIHS between Nov 2015-Jan 2018. Patient characteristics, operative data, clinical outcomes, complications, radiological outcomes, and midterm (24-month) follow-up regarding functionality, pain, and quality of life were analyzed. Patients had thoracolumbar (71.23%), thoracic (10.97%), and lumbar (17.8%) fractures. Operative time was < 120min in 73.97% of patients, with blood loss < 500ml in 97.25% of cases. No in-hospital mortality was recorded. Spine-associated complications occurred in 15.07% of patients, while 36.98% of patients had urinary tract infections (n = 12), pneumonia (n = 5), and electrolyte disturbances (n = 9). The mean length of hospital stay was 13.38 ± 7.20 days. Clinically-relevant screw loosening occurred in 1.7% of screws, and secondary adjacent fractures were diagnosed in 5.48% of patients. The alpha-angle improved significantly postoperatively (mean change: 5.4°) and remained stable for 24 months. The beta-angle improved significantly from 16.3° ± 7.5 to 10.8° ± 5.6 postoperatively but increased slightly to 14.1° ± 6.2 at midterm follow-up. Although no differences were seen regarding baseline data, clinical outcomes, and complications, fracture level significantly altered the COMI score at 24 months with no effect on pain score or quality-of-life. MIHS using polyaxial screws is a safe treatment for single-level osteoporotic spinal fractures. Fracture level did not alter radiological reduction loss; however, it significantly altered patients' function at 24 months.

CNS and Thorax Injury and Associated Risks Factors in Equestrian Sports.

Equestrian sports continue to gain popularity in the United States and are associated with a high injury rate, especially involving the central nervous system and thorax. Due to this high rate of injury and the potential for long-term consequences associated with participation, an understanding of the unique risks of this sport is needed. To describe severe injury in equestrian sports and review the role that protective gear plays in injury mitigation. The PubMed Database was searched using the search terms "equestrian" and "horse" combined with "spinal cord injury," "head injury," "traumatic brain injury," "experience levels," and "demographics." A total of 53 papers were selected based on their relevance of epidemiology, risk factors, and management of injuries sustained during equestrian activities. Case studies, randomized controlled trials, prospective studies, and retrospective studies were all included for further review. Systematic review. Level 4. None. Injuries to the thorax, including fractures, pneumothoraces, internal organ contusions, and crush injuries, have been cited in multiple national and international trauma registries as the most prevalent injury location in equestrians; however, head and neck injuries, high cervical spine fractures, and closed head injuries are reported to be associated with the highest rates of mortality. Helmets provide protection against skull fracture and traumatic brain injury. Vests were not associated with diminished rates of spinal cord injuries; however, they may provide protection to the thorax. Riding experience also plays a role in reducing the prevalence of injury. Equestrian-related activities are associated with a high risk of injury despite protective measures. Protective gear can mitigate some injury risk but does not protect against spinal injury. Continued investigation into improving protective equipment, rider education, and preventative strategies to mitigate this risk is needed.

Cemented in place: kyphoplasty-associated pulmonary cement embolism: a case report

BackgroundKyphoplasty-associated cement extravasation into surrounding tissue and vasculature can lead to life-threatening complications. We present a rare case of significant inferior vena cava cement burden that resulted in pulmonary embolism.Case presentationA 74-year-old Caucasian woman with a history of severe osteoporosis, recurrent falls, and spinal compression fracture status post-kyphoplasty of the L4–L5 vertebrae, presents to the emergency department 2 days post-vertebral kyphoplasty due to chest pain, back pain, and dyspnea. Computed tomography of the chest and abdomen showed a metallic density within the inferior vena cava extending superiorly approximately 10 cm from the vertebral L5 level. She was also found to have right lower lobe pneumonia. The patient finished a 10-day course of antibiotics and was discharged home with a 1-month long course of anticoagulation with apixaban per recommendations of a multidisciplinary team consisting of Hematology/Oncology, Interventional Radiology, Vascular Surgery, and Orthopedic Surgery. Unfortunately, the patient was readmitted a month later with shortness of breath. Work up was notable for an influenza type A infection and computed tomography findings of pulmonary cement embolism. The respiratory distress was resolved with supportive care. Despite pulmonary cement burden, the multidisciplinary care team recommended no further anticoagulation. Patient was discharged home with close clinical follow-up and 6 months has since passed at the time of this report without reported complications.ConclusionsA large cement burden in the inferior vena cava leading to pulmonary cement embolism is a rare event. A high burden of cement predisposes development of pulmonary embolism. A short course of anticoagulation may only be needed for asymptomatic patients.

Potential strength and weakness of artificial intelligence integration in emergency radiology: a review of diagnostic utilizations and applications in patient care optimization.

Artificial intelligence (AI) and its recent increasing healthcare integration has created both new opportunities and challenges in the practice of radiology and medical imaging. Recent advancements in AI technology have allowed for more workplace efficiency, higher diagnostic accuracy, and overall improvements in patient care. Limitations of AI such as data imbalances, the unclear nature of AI algorithms, and the challenges in detecting certain diseases make it difficult for its widespread adoption. This review article presents cases involving the use of AI models to diagnose intracranial hemorrhage, spinal fractures, and rib fractures, while discussing how certain factors like, type, location, size, presence of artifacts, calcification, and post-surgical changes, affect AI model performance and accuracy. While the use of artificial intelligence has the potential to improve the practice of emergency radiology, it is important to address its limitations to maximize its advantages while ensuring the safety of patients overall.

Thoracolumbar injuries: operative treatment: indications, techniques, timing and implant removal. Current practice.

The operative treatment of thoracolumbar fractures is a rapidly evolving improvement in the care of patients with this injury after trauma. This article describes the different techniques and principles. Considerations and methods of treatment are scientifically addressed and illustrated according to the classification and severity of the fracture pattern. The use of computer navigation and optimisation of minimally invasive techniques is inevitable. The timing of surgery as well the removal of the material after fracture healing are also discussed. The operative treatment of spinal fractures is emerging and there is still much more knowledge to gain.

VerFormer: Vertebrae-Aware Transformer for Automatic Spine Segmentation from CT Images.

The accurate and efficient segmentation of the spine is important in the diagnosis and treatment of spine malfunctions and fractures. However, it is still challenging because of large inter-vertebra variations in shape and cross-image localization of the spine. In previous methods, convolutional neural networks (CNNs) have been widely applied as a vision backbone to tackle this task. However, these methods are challenged in utilizing the global contextual information across the whole image for accurate spine segmentation because of the inherent locality of the convolution operation. Compared with CNNs, the Vision Transformer (ViT) has been proposed as another vision backbone with a high capacity to capture global contextual information. However, when the ViT is employed for spine segmentation, it treats all input tokens equally, including vertebrae-related tokens and non-vertebrae-related tokens. Additionally, it lacks the capability to locate regions of interest, thus lowering the accuracy of spine segmentation. To address this limitation, we propose a novel Vertebrae-aware Vision Transformer (VerFormer) for automatic spine segmentation from CT images. Our VerFormer is designed by incorporating a novel Vertebrae-aware Global (VG) block into the ViT backbone. In the VG block, the vertebrae-related global contextual information is extracted by a Vertebrae-aware Global Query (VGQ) module. Then, this information is incorporated into query tokens to highlight vertebrae-related tokens in the multi-head self-attention module. Thus, this VG block can leverage global contextual information to effectively and efficiently locate spines across the whole input, thus improving the segmentation accuracy of VerFormer. Driven by this design, the VerFormer demonstrates a solid capacity to capture more discriminative dependencies and vertebrae-related context in automatic spine segmentation. The experimental results on two spine CT segmentation tasks demonstrate the effectiveness of our VG block and the superiority of our VerFormer in spine segmentation. Compared with other popular CNN- or ViT-based segmentation models, our VerFormer shows superior segmentation accuracy and generalization.

Streamlining the Journey of Research Into Clinical Practice: Making Your Patients and Practice Flourish Optimizing Management and Minimizing Risk of Osteoporotic Vertebral Fractures - Perspectives of the AO Spine KF Trauma and Infection Group Key Opinion Leaders.

Literature review with clinical recommendations. To highlight important studies about osteoporotic spinal fractures (OF) that may be integrated into clinical practice based on the assessment of the AO Spine KF Trauma and Infection group key opinion leaders. 4 important studies about OF that may affect current clinical practice of spinal surgeons were selected and reviewed with the aim of providing clinical recommendations to streamline the journey of research into clinical practice. Recommendations were graded as strong or conditional following the GRADE methodology. 4 studies were selected. Article 1: a validation of the Osteoporotic Fracture (OF)-score to treat OF fractures. Conditional recommendation to incorporate the OF score in the management of fractures to improve clinical results. Article 2: a randomized multicenter study comparing romosozumab/alendronate vs alendronate to decrease the incidence of new vertebral fractures. Strong recommendation that the group receiving romosozumab/alendronate had a decreased risk of new OF when compared with the alendronate only group only. Article 3: a systematic literature review of spinal orthoses in the management of. Conditional recommendation to prescribe a spinal orthosis to decrease pain and improve quality of life. Article 4: post-traumatic deformity after OF. A conditional recommendation that middle column injury and pre-injury use of steroids may lead to high risk of post-traumatic deformity after OF. Management of patients with OF is still complex and challenging. This review provides some recommendations that may help surgeons to better manage these patients and improve their clinical practice.

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

IntroductionFractures 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 MethodsThis 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. ResultsAn 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). ConclusionsThis 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.

Epidemiological characteristics of traumatic spinal fractures among the elderly in China

The exploration of traumatic spinal fractures (TSFs) within the senior demographic has not been thoroughly scrutinized, particularly with respect to variations across genders, age groups, seasonal periods, and causative factors. This retrospective analysis aimed to dissect differences in the prevalence and characteristics of TSFs among the elderly, factoring in gender, age, seasonal timing, and causation. A retrospective analysis was conducted on the medical and imaging records of 1,415 patients, all aged 60 years or older, who were diagnosed with TSFs from 2013 to 2019. This study categorized the data by gender, age groups (60–70, 70–80, and 80 years or older), seasons, and the cause of injuries, including road traffic crashes (RTCs), falls from low heights (LHF), falls from high heights (HHF), and injuries incurred during everyday activities and agricultural labor (DFI). Male patients exhibited notably higher incidences of RTCs, high-height falls (HHFs), outdoor incidents, comas post-injury, fractures of the lower limbs (LLFs), pelvic fractures (PFs), rib fractures (RFs), intra-thoracic injuries (ITIs), intra-abdominal injuries (IAIs), cervical fractures, and spinal cord injuries (SCIs). With advancing age, there was a marked decline in occurrences of RTCs, HHFs, outdoor incidents, RFs, craniocerebral injuries (CCIs), ITIs, cervical fractures, and SCIs, while the incidences of DFIs, indoor incidents, and thoracic and lumbar (T + L) fractures notably increased. During autumn, LLF occurrences were significantly reduced, whereas the winter season saw an increase in thoracic fractures. Spring time was associated with a higher frequency of lumbar fractures and noncontiguous spinal fractures (NSFs). Significant distinctions were observed in the age distribution, injury circumstances, associated injuries, and SCIs between high-energy impacts (RTCs and HHFs) and low-energy traumas (LHFs and DFIs). In the elderly demographic, TSFs exhibited discernible distinctions based on gender, age, seasonal variations, and etiological factors, impacting the nature and circumstances of injuries, associated traumas, complications, fracture sites, and the occurrence of SCIs.
