Open sternal fracture with bilateral dislocation of the sternoclavicular joints after a high-speed bicycle accident: a case report

BackgroundOnly a few cases of bilateral traumatic sternoclavicular dislocations have been reported in the literature. This injury is considered one of the rarest injuries of the human musculoskeletal system. Therefore, we present the first documented case of a cyclist with a third-degree open thoracic trauma (Gustilo–Anderson 3a) associated with a dislocated manubrium sterni fracture in the upper thoracic aperture, bilateral anterior dislocations of the sternoclavicular joints, rib fractures, and pleural ruptures.Case presentationThe patient, a 27-year-old Caucasian male, incurred this injury while participating in a professional cycling race at Nürburgring, Germany and received immediate interdisciplinary surgical treatment and has encountered no complications. We conducted a 1-year follow-up and present the clinical findings of this follow up. Additionally, we conducted a comprehensive review of the existing literature on this injury.ConclusionsImmediate interdisciplinary intervention, including surgical repair and meticulous postoperative care, facilitated successful patient recovery. This underscores the critical role of comprehensive trauma management in complex polytrauma cases. In conclusion, this case report highlights the rarity and complexity of a traumatic injury involving bilateral sternoclavicular dislocation, with this case being the first case reported with concomitant open thorax trauma. Our patient benefited greatly from immediate air-bound transportation to an interdisciplinary care provider, which houses both thoracic and trauma surgery departments.

Correlation Between Reduced Daily Living Competence and the Risk of Postoperative Delirium in Orthopedics and Trauma Surgery

Background/Objectives: Postoperative delirium is a prevalent and serious complication among elderly patients following surgical procedures. Prior research indicates that reduced competence in daily living, as evidenced by limitations in performing Activities of Daily Living (ADL), is directly associated with reduced patient mobility. This study aimed to investigate the potential role of preoperative mobility as a risk factor for the development of postoperative delirium. Methods: To assess preoperative mobility, a comprehensive geriatric evaluation of daily living competence was conducted. This included the Katz Index of Independence in ADL, which assessed basic daily activities over the preceding 14 days, and the Instrumental Activities of Daily Living Scale (IADL). Postoperatively, delirium monitoring was performed twice daily for seven days using validated delirium screening tools, including the Nursing Delirium Screening Scale, the Confusion Assessment Method, and the 4ATest. Results: A significant correlation was observed between the incidence of delirium and the IADL scores in all patients, with p < 0.001 for men and p = 0.001 for women. Among emergency patients, the Katz Index scores significantly differed between those who developed delirium and those who did not (p = 0.015). Additionally, a significant correlation was found between the Katz Index and the incidence of delirium in both groups (p < 0.001). Conclusions: The findings of this study emphasize the necessity of preoperative geriatric assessment using tools such as the Katz Index or IADL to identify patients at risk of delirium. The results confirm the importance of enhanced postoperative monitoring for potential delirium. For elective patients, prehabilitation should be considered when reduced daily living competence is identified. For emergency patients, immediate postoperative interventions, including intensive mobilization and orthogeriatric co-management, are recommended.

The MangLE score: A novel simple tool to identify patients who are unlikely to require amputation following severe lower extremity injury

BACKGROUND There are no validated and sensitive models that can guide the decision regarding amputation in patients with mangled lower extremities. We sought to describe a simple scoring model, the Mangled Lower Extremity (MangLE) score, which can predict those who are highly unlikely to need an amputation as a means to direct resources to this cohort. METHODS This is a retrospective study using the 2013–2021 American College of Surgeons Trauma Quality Improvement Program data set. Adult patients with a mangled lower extremity, defined as a crush injury or a fracture of the femur or tibia combined with severe soft tissue injury, arterial injury, or nerve injury, were included. Patients who suffered a traumatic lower extremity amputation, underwent amputation within 24 hours of admission, or who died within 24 hours of admission were excluded. Patients were divided into those who did/did not undergo amputation during their hospital stay. Demographics, injury mechanism, Injury Severity Score, and Abbreviated Injury Scale score, initial vital signs, and comorbid conditions were abstracted. A logistic regression model was constructed and the top five most important variables were used to create the score. RESULTS The study includes 107,620 patients, of whom 2,711 (2.5%) underwent amputation. The five variables with the highest predictive value for amputation were arterial injury, lower-extremity Abbreviated Injury Scale score of ≥3, crush injury, blunt mechanism, and shock index. The lowest possible MangLE score was 0, and the highest was 15. The model demonstrated an excellent predictive ability for lower extremity amputation in both the development and validation data set with an area under the receiver operating characteristic curve of 0.81 (95% confidence interval, 0.80–0.82) and 0.82 (95% confidence interval, 0.81–0.84), respectively. The negative predictive value for a score of <8 is 99%. CONCLUSION The MangLE score is able to identify patients who are unlikely to require amputation. Resources for limb salvage can be directed to this cohort. LEVEL OF EVIDENCE Prospective and Epidemiologic; Level IV.

Pregnancy and trauma: What you need to know.

Nearly 4% of pregnant patients have an injury-related visit to the emergency department during their pregnancy. There are important physiologic changes that occur during pregnancy that make managing pregnant trauma patients different from the standard management of a nonpregnant patient. This review discusses these changes and the initial assessment, laboratory, and imaging workups for the pregnant trauma patient. In addition, management of specific injuries in pregnancy including pelvic fractures, hemorrhagic shock, and postpartum hemorrhage are reviewed as well as key points regarding resuscitative hysterotomy and fetal support that trauma surgeons should be aware of.

Gender Disparity in Academic Trauma Surgery: The Current State of Affairs.

Despite the increasing number of female surgeons in general surgery programs, women are still inadequately represented in leadership positions. This study aims to investigate the magnitude of gender bias in university-based trauma surgery fellowship programs and leadership positions in the United States of America. FRIEDA was used to identify trauma surgery programs. A thorough website review of each program obtained further information on faculty members, including their name, age, gender, and faculty rank. Trauma surgeons with an MD or DO qualification and a faculty rank of Professor, Associate Professor, or Assistant Professor were selected for inclusion in this study. SCOPUS was used to assess the H-index and the number of publications and citations of surgeons. The total number of programs included was 136, consisting of 715 faculty members. Less than a quarter (n = 166; 23.2%) comprised females and less than one-fifth (n = 30; 19%) of female surgeons were Professors. The difference in the research productivity of male and female trauma surgeons was statistically significant (P < .05), with the average H-index being 10 vs 7.5, respectively, amongst the top 50 surgeons of both genders. Based on a multiple regression analysis, academic rank was significantly associated (P < .05), and gender was not significantly associated (P > .05) with H-index. Gender disparity exists in the field of trauma surgery, as noted in senior faculty ranks and leadership positions. Female-inclusive state policies, appropriate mentorship, and supportive institutions can help to bridge this gap.

Recent advancements and future directions in fracture related infections: A scoping review.

Fracture-related infections (FRIs) are complex challenges in orthopedic and trauma surgery, driving ongoing advancements in diagnostics, therapeutics, and management strategies. This scoping review examines recent progress and future directions in FRI management. Diagnostic enhancements encompass standardized definitions, improved biomarkers, advanced microbiological techniques, and innovative imaging modalities. Promising future diagnostics may include point-of-care testing, advanced imaging with enhanced specificity, and machine learning algorithms. Advancements in implant technology emphasize materials science, surface modifications, and personalized 3D printing, enhancing durability and antimicrobial efficacy. Immunomodulatory therapies targeting T cell dysfunction offer potential in addressing FRI chronicity. Enzybiotics and phages present promising alternatives to combat antibiotic resistance, with enzybiotics demonstrating effectiveness against biofilm-associated infections. Patient optimization, multidisciplinary approaches and specialized reference centers play vital roles in comprehensive FRI management, particularly crucial in resource-constrained settings. Collaboration and investment in research and technology are imperative for harnessing the full potential of these advancements and improving global FRI management outcomes. Addressing these complexities necessitates a multifaceted approach integrating clinical expertise, technological innovation, and global cooperation to optimize patient care and mitigate the burden of FRI worldwide.

Association Between Congenital Heart Disease-Related Diagnosis Codes and Trauma Surgery Outcomes.

Congenital heart disease (CHD) is one the most common congenital anomalies, with a prevalence of 8-10 cases per 1000 live births in the United States. Congenital heart disease has been recognized as a risk factor for poor perioperative and postoperative outcomes in non-cardiac surgery. We aimed to determine if documentation of CHD-related diagnosis codes was associated with similar risks for trauma surgery. Data were acquired from the 2010-2019 American College of Surgeons' Trauma Quality Programs Participant Use Files. This study included trauma patients of all ages with one or more surgical procedures and at least one documented non-trauma (comorbidity) International Classification of Diseases code. Patients were stratified based on presence of CHD-related comorbidity codes vs any other comorbidity. Outcomes included mortality, hospital length of stay (LOS), discharge disposition, and in-hospital complications. Using 1:1 propensity score matching, we matched 215 cases with CHD-related comorbid diagnoses to non-CHD controls. Compared to patients with other comorbidities, patients with CHD-related comorbidites were less likely to be discharged home to self-care (odds ratio: 0.44, 95% confidence interval [CI]: 0.25, 078 P = .005) and tended to have prolonged hospital LOS (incidence rate ratio [IRR]: 1.06, 95% CI: 1.001, 1.13, P = .046). We present the first quantitative multicenter analysis correlating documentation of comorbid CHD-related diagnoses with higher risk of adverse outcomes after trauma surgery. These results support the need to routinely acknowledge and document CHD as comorbidity in trauma admissions that could lead to surgical intervention and for trauma centers to prepare for patients with a possible CHD comorbidity.

Innovative Nanotechnological Approaches in Trauma and Orthopaedic Surgery: A Comprehensive Review

Innovative Nanotechnological Approaches in Trauma and Orthopaedic Surgery: A Comprehensive Review

A Patient-Specific 3D Printed Lingual Nerve Protector in Third Molar Extraction.

We present a novel, patient-specific 3D-printed lingual nerve protector designed to minimize the risk of nerve injury during mandibular third molar extraction, a common cause of lingual nerve damage. Lingual nerve injuries, often resulting from trauma, dental procedures, or maxillofacial surgeries, lead to significant functional impairments. Using computed tomography (CT) data, the custom protector is fabricated through 3D printing with a self-retaining structure to shield the lingual mucosa and nerve. The device effectively separates the lingual nerve from the surgical field without requiring retraction of the lingual flap, thereby reducing the risk of nerve injury and enhancing the safety and ease of the procedure.

Spontaneous transomental hernia: a case report of a rare internal hernia with a challenging diagnosis

Introduction and Importance: Transomental hernia (TOH) is an extremely rare clinical condition that represents 1–4% of all internal hernias. Spontaneous TOH occurs in patients with no history of surgery or previous abdominal trauma. It happens after protrusion of the abdominal viscera, commonly the small bowel loops through a defect on the great omentum. Presentation of the case: We present a case of occlusion due to TOH in a 66-year-old man who underwent a laparotomy, and operative exploration showed 10 cm of small bowel incarcerated through a defect in the right side of the greater omentum of 4 cm in diameter. Discussion: The diagnosis is usually delayed because symptoms are nonspecific. Postoperative morbidity and mortality are important because patients present most frequently with gangrenous bowel, making morbidity and mortality higher. Therefore, it constitutes a critical surgical emergency and must be quickly recognized and managed. Computed tomography (CT) scan plays a prominent role in diagnosis. Midline laparotomy is the main emergency approach for patients with unknown bowel obstruction. Some authors suggest a laparoscopic approach, but it requires a surgeon’s experience and propitious patient’s conditions. Conclusion: TOH is the rarest type of internal hernia with extremely difficult preoperative diagnosis due to nonspecific semiology. This type of hernia has the highest morbidity and mortality rates of all internal hernias. Thus, it must be suspected whenever there is bowel obstruction of unknown origin and quickly managed.

Handy Insights: Could Online Patient-Reported Outcome Measures be used to Assess Hand Injury Rehabilitation?

This protocol explores the use of online patient-reported outcome measures (PROMs) to assess recovery following hand trauma surgery. Hand injuries significantly impact patients’ functional abilities and quality of life, making PROMs crucial for tracking recovery and guiding rehabilitation. This study leverages online versions of the Michigan Hand Outcomes Questionnaire (MHQ) and Hand Injury Severity Score (HISS) to assess patient perceptions of their recovery over time.Our prospective cohort study involves 250 participants who will complete these PROMs at four intervals post-surgery. We aim to understand how demographic factors such as age, gender, and injury severity influence recovery perceptions and outcomes. This research seeks to enhance patient care by identifying factors that influence postoperative outcomes and by tailoring rehabilitation strategies accordingly.•Prospective cohort study following hand trauma surgery.•Online PROMs using the MHQ and HISS.•Data collection at four time points: baseline, 2-4 weeks, 6-8 weeks, and 10-14 weeks post-surgery.By making these tools accessible online, this protocol aims to improve patient engagement, increase response rates, and provide valuable insights to guide personalized rehabilitation strategies.

Post-Operative Recovery and Preparation for Ambulation after Foot and Ankle Surgery

This is a review article that focuses on patient self-recovery, pain modulation without pain medication, edema control and preparation for ambulation after a foot or ankle surgery both elective and traumatic surgical procedures. The available evidence and literature review were limited due to the few studies that are devoted to this area of focus. This review article takes a comprehensive and prescriptive perspective into strategies of the aftermath of the physiological and psychological effects on the body, specifically the lower extremity after foot or ankle surgery. Some of these strategies include initial edema control, nutrition, scar massage and reduction of non-mobile skin from the surgical incision within the surgery. A review of the theory of prehabilitation and examples of therapeutic exercises are explained within the article which target important proximal gait muscles needed for ambulation which can be conditioned with the foot and ankle in a CAM boot or a cast.

Antimicrobial resistance: Biofilms, small colony variants, and intracellular bacteria

Soft tissue and bone infections continue to be a serious complication in orthopedic and trauma surgery. Both can lead to a high burden for the patients and the healthcare system. Musculoskeletal infections can be induced by intraoperative contamination, bacterial contamination of open wounds or hematogenous bacterial spread. During the recent decades, advances were achieved in the understanding of pathogenesis and antibiotic resistance. Despite some progress in the diagnosis and advancing of therapeutic concepts, groundbreaking successful improvement of treatment concepts is still missing. Current therapy concepts are based on the two pillars consisting of surgical debridement with joint or bone reconstruction as well as prolonged antibiotic therapy. An improved understanding of both host and pathogen-related factors leading to treatment failure is essential in musculoskeletal infections. Therefore, this review aims to give an overview of pathogen-related pathophysiology in musculoskeletal infections. It describes defense strategies of pathogens such as (1) biofilm, its development, characteristics, and treatment options. In addition, (2) characteristics of small colony variants and (3) intracellular bacteria are highlighted. Lastly (4) an outlook for potential and promising future therapeutic strategies is provided.

The role of tranexamic acid for infection prevention after fracture fixation

Despite the measures employed, fracture-related infections remain a concern after fracture fixation worldwide. Recently, the role of tranexamic acid as a protective drug against postsurgical infections in joint replacement and orthopedic trauma surgery has been proposed, where tranexamic acid has been associated with less surgical wounds complications and infectious complications including periprosthetic joint infection. The mechanism through which tranexamic acid exerts a protective effect against peri-implant infection is still the subject of debate. Although some authors hypothesize an indirect effect inhibiting the formation of postoperative hematoma, there are several studies that show a direct antibacterial effect of the drug against the capacity of bacterial aggregation, even avoiding biofilm formation, favoring the immune response of the host and the action of antibiotics. The purpose of this narrative review is to show the current role of tranexamic acid in orthopedic trauma, specifically its relationship with the prevention of infections related to implants.

Impact of routine pre-operative risk assessment on patients undergoing emergency major abdominal surgery in a regional Victorian hospital.

Routine preoperative risk assessment (RPRA) using objective risk prediction tools may improve the perioperative outcomes of emergency major abdominal surgery (EMAS). This project aims to identify whether the introduction of RPRA with the 'National Emergency Laparotomy Audit (NELA) Calculator' as standard-of-care for EMAS at a regional Victorian hospital has improved postoperative outcomes, reduced unplanned postoperative critical care unit (CCU) admission rates, and impacted the 'no-lap' rate. An audit was performed including all adult general surgery patients who required EMAS at Bendigo Health between September 2017 and August 2022, including those palliated up-front. Patients requiring surgery for uncomplicated appendicitis, cholecystitis, trauma, and diagnostic laparoscopy were excluded. Patient demographics, preoperative NELA score, CCU admission data and postoperative outcomes were collected and compared between patients undergoing surgery before and after the introduction of RPRA. Six hundred and ninety-one patients were included in the analysis. Median NELA score was 5 (IQR 1.5-11.75). 2.60% of patients were palliated up-front and did not proceed to surgery. Among the 673 operative patients, 30-day mortality was 5.20%. Following the introduction of RPRA there was a significant reduction in the unplanned CCU admission rate, from 9.14% to 3.48% (P = 0.04). There was no change in postoperative mortality, severe complication rate or planned CCU admission rate. RPRA reduced rate of unplanned CCU admissions. Postoperative mortality and complication rates did not change following introduction of RPRA. RPRA appears useful in guidance of preoperative palliative decision-making, but further study is required to validate its use in this context.

Role of liver enzymes in patients with blunt trauma to liver on conservative management

Background: When blunt abdominal trauma occurs, the liver is the organ most often affected. The liver enzymes are often elevated in blunt trauma to the liver. However, the variation of liver enzymes among various grades of liver injury is not clear. The aim of our investigation is to determine the variation of liver enzymes across various grades of liver injury as well as whether it affects any change in management including surgical intervention. Methods: Our research was a prospective observational study. Patients of blunt abdominal trauma having a liver damage which was detected on a contrast CT scan and managed conservatively were included. They were categorized as per the AAST (American Association for the Surgery of Trauma) system. Various biochemical markers including liver enzymes were compared between the groups. Any change in management or need for intervention was found out. Results: A total of 35 patients has been included. Ages between 31 and 40 accounted for the majority of cases (34.3%). Our study showed male preponderance (85.7%). Most patients presented to the hospital within 24 hours of trauma (82.9%). Most of our patients had blood transfusions during their hospital stay (71.4%). AAST grade III injury was predominant (48.6%). Subgroup analysis between minor and major liver injury patients was done. No significant distinction was seen among the two groups concerning the assessed biochemical parameters. No significant variation was observed regarding the necessity for intervention. Conclusions: Liver enzymes can not be used to differentiate among various grades of liver injury. Patients who are managed conservatively can be managed so with close monitoring and supportive treatment without the need for any intervention. However, larger and randomized studies are needed to validate the results.

Case Report: Facial fracture sequelae: the importance of using a specific customized implant (PSI) for orbital reconstruction

The reconstruction of orbital fracture sequelae is a major challenge due to concerns regarding surgical approach and implant stability. Few anatomical sites of such minute size have presented with as much variation in treatment as the orbital floor fractures and related sequelae. Our patient developed sequelae of an orbital fracture over the last 3 years, presenting with dystopia, ophthalmoplegia, and diplopia in the supra- and lateroversion and aesthetic impairment. The variety of implant materials for reconstruction after orbital fractures is extensive, and the decision as to which material to use continues to be debated. The continuing development of computer-aided diagnosis and management and the construction of stereolithographic models offer comparable reproduction of anatomical detail. This technology is described in relation to the planning of trauma surgery and sequelae and the planning of ablative surgery for malignant neoplasms of the head and neck. The use of specific 3D printed titanium implants for bone defects was first reported in cranial reconstruction in 2012, and several studies have reported their use in orbital fractures. The advantages of this implant were increased stiffness, preventing shape loss during placement, a precise fit, and decreased surgical time. However, in the existing literature, the one-piece implant done in this way was a precise fit; therefore, it is possible that navigation between intraoperative anatomical landmarks is lost. However, in cases where reconstruction is difficult, such as extensive orbital wall fractures and large orbital sequelae, the 3D printed implant has been helpful in decreasing surgical time and can be accessed by a limited surgical approach with a precise fit. Our clinical case involved a 37-year-old male patient who experienced severe physical aggression in 2020, amid the COVID-19 pandemic. At the time, due to the overwhelming healthcare demands and resource constraints imposed by the pandemic, immediate surgical intervention for the correction of the fracture was not feasible. As a result of this delay, the patient developed sequelae of the orbital fracture over the last 3 years.

Sonographic anatomy of surgically acquired abdominal pseudohernia—A guide to the documentation of anterolateral integument denervation with ultrasound

AbstractIncisional hernia is a common clinical diagnosis when a patient presents with a post‐surgical abdominal wall bulge. Herniation is a complication that can result from a disruption to the anterior abdominal wall, however other differentials need to be considered to account for a localized prominence of the abdominal integument. One such differential is a pseudohernia; a bulging of an intact abdominal integument without protrusion of abdominal contents. This can occur as a direct consequence of operative trauma and subsequent denervation injury to abdominal wall musculature. Although surgical techniques have been refined to reduce the potential of segmental neuropathy, atrophy of the abdominal wall can be a long term sequalae that clinically mimics that of a hernia. Such an outcome can result from surgical approaches with a particular location and orientation leaving little option to avoid damage to nerves inherent to the area. Damage to these nerves can not only result in abdominal wall laxity but also to the development of further complications that can affect a patient's quality of life. The aim of this article is to increase sonographer awareness of postsurgical pseudohernia of the anterolateral abdominal wall as a differential to incisional hernia, and as such provide guidance on how to demonstrate this anomaly. Considering that pseudohernia and incisional hernia have differing management techniques, the sonographer can play a pivotal role in influencing patient management, negating the need for surgical hernia repair and advocate for a conservative management pathway.

Racial disparities persist in mortality after firearm assault injuries: A national analysis of the Trauma Quality Improvement Program database

ObjectivesIt is unclear whether improvements in the delivery of trauma care over the last decade have diminished racial disparities in mortality after firearm injuries. MethodsThe American College of Surgeons Trauma Quality Improvement Program was queried for patients (≥18 years old) who experienced penetrating firearm assault injuries between 2008 and 2018. Multivariable logistic regression was used to assess the association between mortality and race, controlling for demographics, comorbidities, shock index, injury severity score injury location, and hospital characteristics. ResultsThis retrospective cohort study included 261,116 patients who experienced firearm injuries secondary to assault between 2008 and 2018. Patients most frequently identified as Black (64.1%, n = 167,494), followed by White (16.3%, n = 42,649), Hispanic/Latino (15.7%, n = 41,044), and other racial groups (3.8%, n = 9,929). On multivariable logistic regression, Black patients (odds ratio, 1.53; 95% confidence interval, 1.45–1.62), and Hispanic/Latino patients (odds ratio, 1.11; 95% confidence interval, 1.03–1.19) were more likely to die after a firearm assault injury than White patients. Black patients were more likely to die in the emergency department (62.2%, n = 13,438) compared with White patients (52.7%, n = 2,838), Hispanic/Latino patients (53.0%, n = 2,635), and patients of other races (54.8%, n = 681). Across all years of the study period, Black patients had a greater risk-adjusted mortality rate than White patients and Hispanic/Latino patients. ConclusionSignificant racial disparities in mortality after firearm assault continue to persist. Early death within the emergency department appears to be a significant driver of these persistent disparities.
