Objectives: Early death after trauma has been described several times. Little is known about it after traumatic brain injury (TBI) and decompressive craniectomy (DC). The aim of this study was to characterize patients who die after a TBI and DC during their in-hospital stay. Methods: In a subgroup analysis of a retrospective, multicenter, and observational study, non-survivors from in-hospital stays treated for severe TBI and DC were included. Propensity score matching (PSM) was used. Results: A total of 223 patients with severe TBI were treated with DC, and there were 65 (29.1%) patients who did not survive. Of these, 22 (33.8%) died within the first 24 h. Non-survivors were older (p = 0.010), and pupillomotor dysfunction and a higher heart rate on admission were more common (p < 0.001). PSM patients for overall survival (41, 18.4%) differed in mean heart rate from the deceased (p = 0.030). In a multivariate model, age (OR: 1.045, p = 0.013, CI95%: 1.010 to 1.082), Quick value (OR: 0.965, p = 0.049, CI95%: 0.931 to 1.000), and heart rate (OR: 1.099, p = 0.030, CI95%: 1.009 to 1.197) were confirmed as predictive factors. Conclusions: Even after DC, known factors, such as chronological age and comorbidities, have a significant influence on mortality. The value of DC in an aging society for a particular severity of TBI should be further assessed on the basis of prospective studies. Full article

Background/Objectives: The calcaneus is the most commonly injured tarsal bone, potentially resulting in long-term functional deficiencies and disability. The type of treatment mainly depends on fracture type and morphology. Treatment of these fractures can be challenging due to a limited soft tissue envelope and is frequently associated with complications. The aim of this study was to classify fracture types and identify factors associated with in-hospital complications. Methods: Patients with calcaneal fractures treated at our level I trauma center between 1997 and 2017 were included. Demographic data, comorbidities, fracture characteristics, type of treatment, complications and revisions, compliance and accompanying injuries were evaluated. Results: A total of 238 patients (m = 163, f = 75) at a mean age of 40 years sustaining either uni- or bilateral calcaneal fracture resulting in a total of 288 calcaneal fractures. Concomitant injuries were present in 103 patients (35.9%). Traumatic spine lesions were present in 21.9%. Complications were recorded in 59 fractures (20.5%). Open fractures were more likely to develop complications (76.0% vs. 15.2%, p < 0.001). Significant complication (33% vs. 14%, p < 0.001) and wound complication rates (29% vs. 10%, p < 0.001) were found in multiple-injured patients. All open fractures were surgically treated on the day of admission. In calcaneal fractures with a Böhler angle below 0 degrees, more complications were seen (33% vs. 17%, p < 0.05). Conclusions: High complication rates following calcaneal fractures were detected, with an increased likelihood in open fractures and in patients with multiple injuries. A negative Böhler angle was associated with worse outcomes. Full article

Background: Urinary tract trauma encompasses injuries to the kidneys, ureters, urinary bladder, and urethra and can result from both external and iatrogenic causes. We aimed to evaluate the epidemiology, clinical characteristics, and in-hospital outcomes of urinary tract trauma in Germany. Methods: We analyzed data from the GeRmAn Nationwide inpatient Data (GRAND) registry, provided by the Research Data Center of the Federal Bureau of Statistics, from 2005 to 2023. We included patients admitted to the hospital with kidney, ureteral, urinary bladder, or urethral trauma. We assessed baseline characteristics, perioperative outcomes, surgical interventions, in-hospital all-cause mortality, and trends. Results: We identified 239,657 patients with urinary tract trauma: 109,376 with kidney, 34,330 with ureteral, 57,886 with bladder, and 38,065 with urethral trauma. While the incidence of kidney trauma declined, the incidence of ureteral, bladder, and urethral trauma steadily increased over time. Kidney trauma was the most common trauma, affecting younger males (median age of 47 years), and was associated with in-hospital all-cause mortality of 2.4% and transfusion rates of 15%. Ureteral stenting was necessary in 9.3% and nephrectomy in 2.6% of all patients with kidney trauma. Moreover, ureteral, bladder, and urethral trauma predominantly affected older, multimorbid patients, leading to higher rates of transfusion (22–25%), intensive care unit admission (12–15%), and mortality (3.2–6.4%). Ureteral anastomosis was necessary in 14% of all ureteral injuries. Bladder repair was required in 53% of all patients with bladder injury, while 1% of these patients required cystectomy. Accordingly, urethral reconstruction was performed in 7.2% of all patients with urethral trauma. Conclusions: These findings highlight the evolving landscape of urinary tract trauma and underscore the need for tailored management strategies and preventive measures. Full article

Objective: Potassium levels (KLs) influence clinical outcomes in severe traumatic brain injury (TBI). This study investigates the relationship between KLs and clinical outcomes to improve prognosis and guide management. Method: A retrospective study was conducted at a level 1 trauma center in Queens, New York, from January 2020 to December 2023. Patients with an AIS score of 3 or higher were included. KLs were measured at the time of hospital admission, ICU admission, ICU discharge, hospital discharge, and death, if applicable. Clinical outcomes such as age, race, length of hospital stay (H LOS), ICU length of stay (ICU LOS), ventilation days (VDs), Glasgow Coma Scale (GCS), and mortality were assessed. Results: KLs were categorized into five groups: extreme hypokalemia (<2.5 mEq/L), hypokalemia (2.6–3.5 mEq/L), normokalemia (3.5–5.2 mEq/L), hyperkalemia (5.2–7.0 mEq/L), and extreme hyperkalemia (>7.0 mEq/L). Significant correlations were observed between KLs at hospital admission and age (p = 0.0113), race (p = 0.003), and H LOS (p = 0.079). ICU KLs showed positive correlations with AIS head score (p = 0.038), ISS (p = 7.84 × 10⁻⁶), and GCS (p = 2.6 × 10⁻⁶). ICU KLs were also associated with LOS in the Emergency Department (ED) (p = 6.875 × 10⁻⁶) and ICU (p = 1.34 × 10⁻²¹), as well as VDs (p = 7.19 × 10⁻⁷). ICU discharge KLs correlated with ISS (p = 2.316 × 10⁻³), GCS (p = 2.201 × 10⁻³), ED LOS (p = 3.163 × 10⁻⁴), and VDs (p = 7.44 × 10⁻⁴). KLs at discharge were linked with mortality (p < 0.0001) and H LOS (p = 0.0091). Additionally, KLs at the time of death were correlated with ISS (p = 0.01965), GCS (p = 0.01219), ED LOS (p = 0.00594), ICU LOS (p = 0.049), VDs (p = 0.00005), and mortality (p < 0.0001). Conclusions: Potassium imbalances, especially hypokalemia, significantly affect outcomes in severe TBI patients. Monitoring and managing KLs may improve prognosis. Full article

Background: Necroptosis, a regulated form of inflammatory cell death, is increasingly recognized as a key driver of sepsis and critical illness. The balance between necroptosis and apoptosis may influence immune responses and outcomes in ICU patients. Objective: To evaluate necroptosis- and apoptosis-related protein expression in critically ill pediatric and adult patients with sepsis/septic shock, trauma/SIRS, or cardiac conditions, and assess their association with clinical outcomes. Methods: In this prospective, observational study, 88 patients admitted to a tertiary ICU were categorized into four groups: sepsis/septic shock, trauma/SIRS, cardiac disease, and healthy controls. Serum levels of RIPK1, RIPK3, MLKL, A20, caspase-8, IL-1β, and IL-18 were measured within 24 h of admission using ELISA. Biomarkers were analyzed by disease group, age, and severity indices. Results: Patients with sepsis—both adults and children—exhibited significantly elevated levels of RIPK1, IL-1β, and IL-18 (p < 0.001) and reduced levels of caspase-8 (p = 0.015), indicating activation of the necroptosis pathway. A20 was significantly upregulated (p < 0.001) and independently associated with lactate levels. RIPK1, IL-1β, and IL-18 were positively correlated with ICU length of stay and illness severity, whereas caspase-8 showed an inverse correlation. ROC analysis demonstrated strong predictive performance for sepsis/septic shock using RIPK1 (AUC = 0.81), IL-18 (AUC = 0.71), and A20 (AUC = 0.71); conversely, caspase-8 was inversely associated with sepsis (AUC = 0.32). Conclusions: Necroptosis appears to play a central role in the pathophysiology of sepsis across age groups. Elevated levels of RIPK1, IL-1β, IL-18, and A20 may serve as biomarkers of disease severity, while reduced caspase-8 supports a shift away from apoptosis toward necroptotic cell death. These findings highlight the potential of necroptosis-related pathways as targets for risk stratification and therapeutic intervention in critically ill patients of all ages. Full article

Objectives: Carbapenem-resistant Gram-negative bacteria (CR-GNB) infections in intensive care units (ICUs) are increasingly prevalent and associated with high mortality. This study aimed to investigate the distribution of isolated bacteria and determine the factors associated with mortality among ICU patients diagnosed with CR-GNB infections. Methods: This retrospective study included 95 patients admitted to the ICU between February 2022 and July 2024 who were diagnosed with CR-GNB infections via culture and initiated on treatment. Thirty-day mortality was defined as the clinical outcome, and patients were divided into two groups: survivors (Group 1, n = 42) and deceased (Group 2, n = 53). Demographic, clinical, laboratory, and microbiological data were analyzed. Results: Advanced age, the presence of malignancy, an elevated Charlson Comorbidity Index (CCI), lower platelet counts, and higher C-reactive protein (CRP) levels were significantly associated with mortality (p < 0.05). Trauma-related admissions were more common among survivors, while sepsis-related admissions predominated among non-survivors. No statistically significant associations were observed between antibiotic regimen type and mortality. Culture-based pathogen distribution revealed A. baumannii as the predominant organism in respiratory samples, while K. pneumoniae was more frequently isolated from bloodstream and urinary specimens. Conclusions: Mortality in ICU patients with CR-GNB infections is influenced by both baseline comorbidities and infection-related inflammatory markers. This study provides region-specific insights from a high-resistance ICU setting and may inform risk stratification, prognostication, and management strategies in critically ill patients with CR-GNB infections.

Background/Objectives: As the incidence of diabetes mellitus (DM) is increasing rapidly worldwide, it is anticipated that an increasing number of women will enter pregnancy with pregestational diabetes mellitus (PGDM) in the future. Compelling evidence suggests that hyperglycemia in pregnancy is related to multiple adverse perinatal outcomes. This systematic review and meta-analysis aims to assess and quantify the association of PGDM with a range of adverse perinatal outcomes, providing a comprehensive understanding of its impact on pregnancy. Methods: The data sources of this systematic review and meta-analysis were Medline/PubMed, Scopus and Cochrane Library (January 1999 to August 2023), complemented by hand-searching for additional references. Observational studies reporting perinatal outcomes of pregnancies with PGDM diagnosed before pregnancy versus control pregnancies were eligible for inclusion. A systematic review and meta-analysis were conducted as per the PRISMA guidelines. Pooled estimate odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to determine the risk of adverse pregnancy outcomes between PGDM and control pregnancies. Results: The systematic search of the literature yielded 81 observational studies meeting inclusion criteria and in total, 137,237,640 pregnancies were included in the analysis. A total of 19 adverse perinatal outcomes were assessed, revealing a significant association with PGDM. In pregnancies with PGDM there was an increased risk of adverse perinatal outcomes, including gestational hypertension (OR 3.16, 95% CI 2.65–3.77), preeclampsia (OR 4.46, 95% CI 3.94–5.05), preterm delivery (OR 3.46, 95% CI 3.06–3.91), cesarean delivery (OR 3.12, 95% CI 2.81–3.47), induction of labor (OR 2.92, 95% CI 2.35–3.63), macrosomia (OR 2.23, 95% CI 1.76–2.83), LGA neonates (OR 3.95, 95% CI 3.47–4.49), low 5-min Apgar score (OR 2.49, 95% CI 2.07–2.99), shoulder dystocia (OR 3.05, 95% CI 2.07–4.50), birth trauma (OR 1.40, 95% CI 1.22–1.62), polyhydramnios (OR 5.06, 95% CI 4.33–5.91), oligohydramnios (OR 1.61, 95% CI 1.19–2.17), neonatal hyperbilirubinemia (OR 3.45, 95% CI 2.51–4.74), neonatal hypoglycemia (OR 19.19, 95% CI 2.78–132.61), neonatal intensive care unit (NICU) admission (OR 4.54, 95% CI 3.87–5.34), congenital malformations (OR 2.44, 95% CI 1.96–3.04), stillbirth (OR 2.87, 95% CI 2.27–3.63) and perinatal mortality (OR 2.94, 95% CI 2.18–3.98). Subgroup analyses indicated a higher risk of neonatal hypoglycemia, stillbirth and perinatal mortality in T1DM pregnancies compared with T2DM pregnancies. Conclusions: This study provides a robust synthesis of evidence underlying the strong association between PGDM and several adverse perinatal outcomes. Early detection, optimal glycemic control during the periconceptional and pregnancy periods, and proper antenatal care are critical to mitigate these risks. Full article

Background/Objectives: Perineal obstetrical trauma sustained during vaginal delivery has a profound impact on female quality of life. The aim of the cross-sectional study was to analyze the association between active bacterial cervical infection and group B Streptococcus (GBS) rectovaginal colonization in the 35th–37th weeks of pregnancy with the degree of delivery perineal trauma. Methods: The study included 778 women after vaginal delivery. Maternal characteristics, including age, concomitant diseases, parity, obstetrical history, and cervical swab results conducted at admission and rectovaginal bacterial swabs at the 35th–37th weeks of pregnancy, were analyzed. The rates of perineal tears were compared between the physiological and pathological cervical swab groups and between the GBS-positive and GBS-negative colonization groups. Results: At admission to delivery, active cervical infection was diagnosed in 269 (35.9%) women. After vaginal delivery, 361 (49.3%) women had an intact perineum, and 288 (39.3%), 78 (10.7%), 4 (0.6%), and 1 (0.1%) had 1st–4th-degree perineal tears, respectively. Statistical analyses of the logistic regression model found that GBS colonization at the 35th–37th weeks of pregnancy (OR 1.56, p = 0.035) and pathological flora at admission (OR 1.54, p = 0.019) were associated with perineal tears. A higher vaginal parity was found to be a protective factor (OR 0.49, p < 0.000). Conclusions: High birthweight, longer second stage of labor duration, and primiparity were associated with increased rates of perineal trauma. Active cervical infection at admission and GBS colonization at the 35th–37th weeks of pregnancy were found to be risk factors for perineal tears. A protective factor for an intact perineum was a higher number of prior vaginal deliveries. Full article

Objectives: This study aimed to describe the profile and identify the clinical and sociodemographic factors associated with emergency department (ED) use among patients aged ≥65 years. Methods: This was a retrospective cross-sectional study of patients aged ≥65 years who were seen in the emergency department of the Hospital de Mérida (Spain) in 2019, the year before the Coronavirus Disease 2019 (COVID-19) pandemic. Descriptive statistics were calculated for dependent variables such as hours of ED stay, total number of visits, reasons for discharge, and diagnostic specialty, disaggregated by gender, season, age group, day type (work or holiday), shift, and population area (rural or urban). Results: Significant differences in ED hours were found according to gender (p < 0.001), season (p = 0.024), age group (p < 0.001), attention shift (p < 0.001), and population area (p = 0.003). Discharge to home was the most common destination (63.5%), followed by hospital admission (25.7%). Admissions for gastrointestinal surgery and neurology were predominant in men, and admissions for internal medicine and trauma were predominant in women. Patients aged 65–79 years were admitted to internal medicine, and those over 80 years were admitted to cardiology. Among patients who presented to the hospital’s emergency department and required admission, 51.5% were men aged ≥ 75 years, rising to 53.3% among those aged 65 to 74 years. The clinical areas were related to cardiology (27.67%) and pneumology (20.63%). Conclusions: Demands for ED care in those over 65 years of age are associated with sociodemographic and clinical characteristics, which can be used to better plan and manage resources and improve user satisfaction.

Background/Objectives: This study investigates the evolution of hospital capacity and utilization in California between 2003 and 2023, focusing on emergency departments (EDs) and trauma centers (TCs). We seek to document structural changes in the healthcare delivery system with respect to hospital-based emergency and trauma services. Methods: This analysis examines changes in population demographics, hospital resources, and patient utilization patterns across facility types. Given the significant increase in the proportion of the population aged 65+ and the documented higher use of emergency and trauma services by this population, we expected to observe an expansion in ED and trauma service capacity and utilization. Results: Utilizing a comprehensive dataset of California general acute care hospitals over this 20+ year period, our descriptive analysis reveals major shifts in the healthcare delivery system, notably the increased prominence of hospitals with EDs, particularly those designated as trauma centers. Findings indicate that, while the overall number of hospitals and licensed beds has slightly decreased, facilities with EDs, especially trauma centers, have increased their capacity and manage a greater proportion of inpatient admissions and ED visits. Conclusions: The increase in ED visits and inpatient admissions at trauma centers, contrasted with decreases in both capacity and utilization at non-trauma hospitals, indicates a significant restructuring of the health delivery system with significant implications for healthcare policy, financing, operations, and affordability. The high and increasing percentage of inpatient admissions originating from hospital EDs and from hospitals with trauma centers suggests a need for policies that foster integration between ED and inpatient care and the broader healthcare delivery system, while at the same time managing the increase in prices and costs associated with growing emergency services utilization. Further research is needed to explore the implications of these trends, particularly concerning their impact on the affordability of healthcare in the US. Full article

Background/Objective: South Korea continues to have the highest suicide rate among the Organization for Economic Co-operation and Development (OECD) countries, with a growing number of emergency department (ED) admissions related to self-harm and suicide attempts. However, trauma-focused analyses that integrate psychiatric profiles and suicide mechanisms remain limited, hindering effective clinical care and preventive strategies. Methods: This retrospective study analyzed trauma patients who presented to the ED of Wonju Severance Christian Hospital following suicide attempts between October 2015 and December 2023. Of 305 self-harm cases, 208 survivors who underwent psychiatric evaluation were included. The variables analyzed included the mechanism, site, and severity of injury (ISS and AIS); psychiatric diagnosis and prior psychiatric history; repeated suicide attempts; alcohol use; physical pain; interpersonal conflict; and economic vulnerability. Chi-square, Fisher’s exact, and Kruskal–Wallis’ tests were used for statistical comparisons. Results: Stabbing/cutting (56.7%) and falling (35.6%) were the most common attempts. Mood disorders were the predominant psychiatric diagnosis (63.9%), followed by adjustment disorders (26.0%), alcohol use (25.5%), and psychotic disorders (22.1%). Among the fall-related cases, patients were typically younger and predominantly women. The median ISS was highest in fall-related cases (17) compared with stabbing/cutting (4), with 25.96% of patients with an ISS ≥16, indicating severe trauma. A psychiatric history was associated with a higher incidence of falls (44.3%), and previous suicide attempts correlated with the use of high-lethality attempts. Severe physical pain was linked to stabbing/cutting in 10 of 11 cases. Interpersonal conflict was more frequently associated with stabbing/cutting (59.6%) than with falls (31.9%). No significant association was found between alcohol use and the method of suicide attempt. Conclusions: The suicide mechanisms in patients with trauma are closely associated with psychiatric and psychosocial factors. Stabbing/cutting is often impulsive and driven by interpersonal conflict or alcohol use, while falling is more frequent in patients with psychiatric histories of repeated attempts. These findings emphasize the importance of mechanism-informed psychiatric evaluations and trauma protocols. Regionally adapted, interdisciplinary approaches and early psychiatric intervention are crucial for effective post-attempt management and suicide prevention. Full article

Background: Percutaneous screw fixation has increasingly been used for pelvic ring fracture fixation. In older adult patients, especially in patients with a fragility fracture of the pelvis (FFP), minimally invasive techniques followed by early ambulation have been promoted in order to regain pre-injury levels of mobility and independence. The purpose of this study was to evaluate patient-centered outcomes, including post-operative pain relief, functional performance, and satisfaction, in older adults with pelvic ring fractures treated with percutaneous screw fixation and to assess injury characteristics, complications, and return-to-home rates. Methods: In this retrospective cohort study, patients 50 years and older who had their pelvic fracture treated in the Amsterdam UMC location AMC between January 2019 and December 2022 were identified. After a minimum follow-up period of 6 months, a questionnaire was conducted by phone to evaluate the pain, current living situation, and mobility of the patients. Results: A total of 51 patients were included in this study with a median age of 74 years (IQR 62–82), and the vast majority were female (n = 40, 78%). Over half of the pelvic fractures were caused by low-energy trauma (n = 29, 57%). Unilateral or bilateral sacral fractures with unilateral anterior ring fractures were the most common fracture pattern. The interoperative complication rate was 4%, and the in-hospital complication rate was 23%. Forty-five patients were reached to complete the questionnaire. Forty patients (91%) returned to an acceptable level of mobility after treatment, and almost all (n = 44, 98%) were pleased with the results of the surgery. Conclusions: Percutaneous screw fixation of pelvic fractures in older adult patients is a safe and effective operating technique. Most patients preserve their pre-morbid functionality and are able to return to their previous place of residence after admission. Furthermore, patients are almost unanimously very pleased with the results of the surgery despite some residual pain complaints. Full article

Introduction: Traumatic brain injury (TBI) remains a significant challenge in older polytrauma patients, with age being a major determinant of outcomes. While mortality predictors have been studied in general polytrauma populations, less is known about specific risk factors in older adults with TBI. Methods: This retrospective study analysed data from 304 polytrauma patients over 18 years of age treated at a Level 1 trauma centre between 2013 and 2023. Patients were divided into three age categories: 18–64 years (n = 189), 65–84 years (n = 92), and ≥85 years (n = 23). The analysis included demographics, injury patterns, clinical indicators, surgical treatments, and in-hospital mortality to identify key mortality predictors. Results: The mean age was 54.5 years (SD 22.2); 72% of patients were male. In-hospital mortality was 36.3% overall, increasing to 60.8% in patients aged ≥85. TBI severity was moderate in 25% and severe in 75% of cases. Older patients were less frequently admitted to the ICU and more often managed conservatively. ICU admission was significantly lower in patients aged 65–84 (24.5%) and ≥85 (19.4%) compared to the 18–64 group (70.0%). Multivariate analysis identified age, male sex, and severe TBI as significant predictors of 30-day mortality. Conclusions: TBI management in older polytrauma patients requires distinct approaches due to higher mortality and poorer outcomes. Age is a critical risk factor, highlighting the need for tailored triage systems and ICU strategies to improve care and prognosis in this vulnerable population. Full article

Background: The clinical significance of serum potassium levels at admission in patients with blunt hepatic trauma remains insufficiently defined. This study aimed to evaluate the prevalence and prognostic value of admission hypokalemia in this patient population. Methods: We conducted a retrospective analysis of 164 patients with radiologically confirmed blunt liver trauma admitted between 2016 and 2023. Preoperative, intraoperative, and postoperative data were collected to assess the association between serum potassium levels and trauma severity (AAST grade—American Association for the Surgery of Trauma, ISS—Injury Severity Score), in-hospital morbidity, mortality, and length of stay. Univariate and multivariate analyses were performed, including checks for normality and multicollinearity. Results: Serum potassium levels showed a significant positive correlation with age (p = 0.0064), and an inverse correlation with liver injury severity (AAST grade; p = 0.01). Lower potassium levels were associated with longer hospital stays (p = 0.0459) and higher morbidity (p = 0.022). In multivariate analysis, only age (p = 0.036) and AAST grade (p = 0.014) were independent predictors of serum potassium concentration. Potassium levels were not independently associated with mortality. Conclusions: Admission hypokalemia is a common finding in blunt liver trauma and correlates with injury severity and adverse clinical outcomes. Potassium concentration may serve as a readily available, low-cost biomarker for early risk stratification in these patients. Further prospective studies are warranted to confirm its prognostic utility. Full article

Background: Flail chest (FC) injuries are multiple adjacent segmental rib fractures, commonly associated with a high complication and mortality risk. Recent evidence suggests that the early surgical stabilization of FC injuries is beneficial for restoring breathing mechanics. However, little is known about the effects on lung volumes when invasive ventilation is performed after surgery. Methods: This retrospective study included multiple trauma (MT) patients operatively treated for an FC injury between 2011 and 2024. The indication for surgery was based on a computed tomography (CT) proof of an FC, objectifiable paradoxical breathing, and prolonged weaning. All patients treated used a single osteosynthesis system. Lung volumes were manually measured in preoperative and postoperative CT scans of the thorax in the thinnest CT reconstructions available. The primary outcomes of interest were the changes in the lung volumes following surgical stabilization of the FC. Results: During this study, 21 patients (90.48% male) were operatively treated for their FC injury. All patients had been affected by high-energy trauma. The corresponding median Injury Severity Score (ISS) was 26 (IQR 17.5, 33). Patients suffered 7 (IQR 6, 10) and 6 (IQR 2, 9) fractured ribs of the left and right hemithorax, respectively. Three (IQR 0, 3) and two (IQR 0, 3) ribs of the left and right hemithorax, respectively, were stabilized at 7 (IQR 2, 18) days post admission. There were no significant changes in the lung volumes comparing preoperative and postoperative CT scans. Conclusions: As this study did not detect CT volume changes comparing preoperative and postoperative scans, CT scans following surgery may not qualify for an objective measurement of the surgical effectiveness regarding lung volume restoration in the short-term follow-up. Long-term changes in CT-measured lung volume changes need to be evaluated to prove an objective surrogate parameter for surgical effectiveness regarding the restoration of the thorax integrity.
