Purpose: Knowledge about factors associated with mortality after hip fracture is important both for analytical and clinical purposes. This study aimed to assess patient risk factors and commonly used composite scores for prediction of 1-year mortality in a large clinical cohort.

Methods: Hip fracture patient data were prospectively recorded in a local hospital database. Consecutive fractures from 2006 to 2020 were included, 6040 fractures in 5496 patients. Associations between 1-year mortality and different exposures were estimated using univariate and two multivariate logistic regression models. ROC analysis was used to compare the ability of the Nottingham Hip Fracture Score (NHFS), Age-adjusted Charlson Comorbidity Index (ACCI) the American Society of Anesthesiologists score (ASA) and the Orthopedic Frailty Score (OFS) to predict 1-year mortality.

Results: Females sustained 73.9% of the fractures. Total 1-year mortality was 24.8%. Patients with overweight and class 1 obesity had lower 1-year mortality rates than normal weight patients [overweight: adjusted OR 0.58 (0.45-0.77), class 1 obesity: adjusted OR 0.40 (0.21-0.75)]. Mortality was elevated in males (adjusted OR 2.04, 95% CI 1.76-2.36), and nursing home residents (adjusted OR 2.99, 95% CI 2.60-3.44). We found no significant association between waiting time before surgery and mortality. Models including ACCI (AUC 0.74), NHFS (AUC 0.75) and OFS (AUC 0.73) had a similar ability to predict 1-year mortality, while a model including ASA (AUC 0.71) had a significantly lower prediction ability than ACCI and NHFS.

Conclusions: Sex, age, cognitive impairment, and residential status predicted 1-year mortality. The study found an apparent "obesity paradox", where overweight patients had a lower mortality rate than normal weight patients, but unmeasured confounding may have biased this analysis. ACCI and NHFS predicted mortality better than the combination of age, sex, and ASA.

Purpose: Self-inflicted injuries are a leading cause of death in young adults. Trauma to the anterior neck, such as from cutting and hanging, can have serious consequences given the complex anatomy and closeness of critical structures. Considering the recent increase in intended and inter-personal violence, we evaluated the occurrence and clinical characteristics of self-harm neck injuries in young adults.

Methods: We retrospectively reviewed all neck traumas treated at the Helsinki University Hospital in patients aged 18 to 30 years in 2005-2023. Patient records were systematically evaluated for cohort demographics, injury type, clinical characteristics, given treatment, follow-up, and possible psychiatric comorbidities.

Results: In total 169 events were recorded, with an evident increase in the recent years (45% of all in 2020-2023) and particularly in females. Females were younger than males (p = 0.010) and their trauma generally milder, often managed in outpatient care (82%). Severe penetrating injuries occurred primarily in males (p = 0.005) who were older (p = 0.004) and without prior suicidal events (p = 0.005). They required surgical interventions and prolonged in-house treatment. Overall, the cohort was characterized by a heavy burden of psychiatric comorbidities (98%) and substance abuse (53%); 78% had other suicidal events. Four patients (2.9%) deceased from a recorded suicide during the study period.

Conclusions: We report an alarming increase in suicidal self-harm especially among young females and severe intended neck traumas in older males without preceding suicidal behavior. Our findings warrant timely preventative actions on an individual and societal level and call for refined guidelines for clinical management.

Purpose: The purpose of this study was to assess severe abdominal injury in child passengers of different ages of motor vehicle accidents and analyze the concomitant pattern of injury regarding injury severity, trauma management and outcome.

Method: Data acquisition from Trauma Register DGU^® (TR-DGU) in a 10-years period (2010-2020) of seriously injured children (max. AIS 2+ / intensive care) 0-15 years of age, as motor vehicle passengers (cMVP) (n = 1,035). Primarily treated in or transferred to a German Trauma Center. Matched pairs analysis with adult severely injured motor vehicle passengers (aMVP) (age 20-50 years, n = 26,218), matching 1:4 (child: adult), was performed to identify causes of mortality.

Results: The study group (cMVP) included 1,035 children. The mean age was 9.5 years, 50.5% were male and the mean Injury Severity Score (ISS) was 18.7 points. 93.0% were transported from scene directly to the final trauma center. Transferred patients showed a higher ISS (26 vs. 18 points), higher rate of severe traumatic brain injury (TBI), a higher rate of serious abdominal injury and a higher mortality rate (12.5% vs. 7.4%). Most of the severe abdominal injuries occurred after the third year of age (first peak between 8 and 9 years; second peak 14-15 years). Serious injuries to the pelvis show a similar distribution but less often, the same applies to thoracical injuries. Severe brain and head injuries show an antiproportional distribution to the age groups with the highest rate in the 0-1 year old (78%) and the lowest in the 14-15 year old (40%). The highest mortality rate was shown in the youngest age groups, related to TBI (AIS_TBI ≥ 3; 62% in 0-1 years). The matched pairs analysis shows a higher mortality rate of cMVP compared to aMVP within the first 24 h after hospital admission and a significantly higher rate of shock and unconsciousness, while the intubation rate is significantly lower.

Conclusion: Child passengers of motor vehicle accidents are in need of a specific and age-related attention towards security systems. Severe injuries in children are rare, yet life threatening. The highest mortality rate is related to severe TBI, especially in the youngest children. But also severe abdominal as well as thoracic injuries their concomitant trauma need to be prevented and are indicators for even more severe injuries. It seems to be favorable for cMVP to be directly transported to designated special centers with sufficient capacity and competency to treat and manage severely injured children.

Trauma systems are vital components of healthcare infrastructure, addressing the significant burden of severe injuries across Europe. Effective trauma systems improve patient outcomes and reduce mortality by providing timely, specialised care. However, significant disparities remain between countries, with only a few well-structured and maintained systems currently operating in Europe.Developing trauma systems requires collaboration among healthcare providers, emergency services, and government agencies. Standardised protocols for triage, transport, and treatment are essential, supported by robust infrastructure, public education, and injury prevention initiatives.Trauma systems comprise four core components:• Injury Prevention.• Pre-Hospital Care.• Facility Care.• Post-Hospital Care/Rehabilitation.These components rely on key elements such as leadership, professional resources, education, quality improvement, and funding. Political commitment, geographical considerations, and the efforts of dedicated clinicians are crucial for ensuring system success.Trauma systems across Europe are evolving under diverse healthcare structures. Over recent decades, dedicated clinicians, often with support from national medical societies, have initiated and sustained these systems. Typically, trauma hospitals, or trauma centres (TCs), are categorised into two or three levels, with the highest being 'Level I TC' or 'Major TC,' capable of managing the most complex cases. This chapter outlines general requirements for these categories, leaving individual nations to tailor standards to their healthcare systems.

The reconstruction of large bone defects remains challenging for orthopedic surgeons. Autologous bone grafts (ABGs) are the gold standard treatment for limited size defects, but larger bone defects (> 5 cm) require the use of more sophisticated techniques, such as the Masquelet technique. Over the last three decades, the Masquelet or induced membrane technique (IMT) has become increasingly popular as it does not require high-precision microsurgery skills and the time taken to achieve bone consolidation is independent of the length of the defect. IMT is a two-stage procedure. In the first stage, a polymethylmethacrylate (PMMA) cement spacer is implanted into the bone lesion and a physiological immune reaction initiates the formation of a fibrotic induced membrane (IM) with both angiogenic and osteogenic properties. The second stage, performed several weeks later, involves removal of the spacer followed by the implantation of a standard ABG in the preserved IM cavity for subsequent bone repair. In this extensive review, we explain how the success of this surgical procedure can be attributed to the synergy of four key components: the inducer (the PMMA cement), the recipient (the IM), the effector (the bone graft) and the modulator (the mechanical environment). Conversely, we then explain how each key component can contribute to the failure of such treatment. Finally, we discuss existing or emerging innovative and biotechnology-oriented strategies for optimizing surgical outcome with respect to the four components of IMT described above.

The International Health Facility Guidelines 2023 provide critical recommendations for operating room (OR) design and management, addressing layout, equipment specifications, and safety protocols. By adhering to these guidelines, healthcare facilities can ensure optimal conditions for surgical procedures, minimise risks to patients and staff, and enhance overall efficiency. These recommendations serve as a vital resource for healthcare administrators, architects, and medical personnel, facilitating high-quality surgical care and improved outcomes for trauma patients.

Purpose: In patients with hemorrhagic shock and an intracranial space occupying lesion (SOL), brain perfusion is severely compromised due to raised intracranial pressure (rICP), significantly worsening outcomes. This study aims to develop a swine model of a SOL with rICP and shock and characterize the effect on brain perfusion.

Methods: Ten male swine were divided into two groups- normal ICP (nICP) and rICP. rICP animals had an intracranial Fogarty balloon catheter inserted, which was infused with saline to simulate a SOL. Animals underwent hemorrhage to systolic blood pressures (SBP) of 60, 40, and 20mmHg. Cerebral blood flow (CBF) and cerebral blood volume (CBV) were measured using CT perfusion.

Results: The CBF/Mean arterial pressure (MAP) and CBV/MAP curves were modeled using non-linear regression, with both groups demonstrating a sigmoid relation. In both the CBF/MAP and CBV/MAP curves, animals with rICP had loss of autoregulation at a higher MAP compared to nICP. The curves were an excellent fit for CBF (nICP R² = 0.95; rICP R² = 0.77) and CBV (nICP R² = 0.96; rICP R² = 0.78).

Conclusions: This study aids in quantifying the compounding insult of raised ICP and hemorrhage with regard to brain perfusion. Raised ICP results in autoregulatory failure at a higher MAP compared to animals with nICP. These results can help inform future studies that should be aimed at evaluating novel interventions for this complex clinical scenario.

Effective shock (or trauma) room management requires thorough preparation, staff competence, dedicated infrastructure and organised protocols. Shock rooms must be sufficiently equipped according to the hospital's designated level of care. This chapter outlines essential aspects, including equipment and facilities, staff qualifications and composition, and communication practices. Key areas including initial assessment, diagnostic procedures, emergency interventions, and future aspects in the care of severely injured patients are addressed, along with emerging innovations in trauma care.

Purpose: Our aim was to update the evidence-based and consensus-based recommendations on criteria for trauma team activation (TTA) and staffing requirements for the management of patients with (suspected) multiple and/or severe injuries in the resuscitation room on the basis of available evidence. This guideline topic is part of the 2022 update of the German Guideline on the Treatment of Patients with Multiple and/or Severe Injuries.

Methods: MEDLINE and Embase were systematically searched to August 2021. Further literature reports were obtained from clinical experts. Randomised controlled trials, prospective cohort studies, cross-sectional studies and comparative registry studies were included if they compared criteria for identifying severely injured patients requiring trauma team activation or different staffing components (e.g. team composition, training) for the management of patients with (suspected) multiple and/or severe injuries in the resuscitation room. We considered patient relevant outcomes such as mortality as well as prognostic accuracy outcomes. Risk of bias was assessed using NICE 2012 checklists. The evidence was synthesised narratively, and expert consensus was used to develop recommendations and determine their strength.

Results: Twenty-one new studies were identified. Potential trauma team activation criteria included vital signs (e.g. systolic blood pressure), type and extent of injury (e.g. central gunshot wound), mechanism of injury (e.g. traffic accident), interventions (e.g. chest tube), specific criteria for geriatric patients, and combined criteria (N = 20). Staffing requirements for the resuscitation room included specific training for orthopaedic trainees (N = 1). Two recommendations were modified, and six additional recommendations were developed. All but two recommendations achieved strong consensus.

Conclusion: The key recommendations address the following topics: inter-professional trauma teams in the resuscitation room; trauma team activation for geriatric patients; and trauma team activation criteria based on physiological, anatomical, interventional, and mechanism of injury parameters.

Purpose: Current literature lacks recommendations regarding proper fixation of tibial tubercle avulsion fractures involving the proximal tibial epiphysis (Ogden fractures). Therefore, the aim of this study was to compare isolated apophyseal screw fixation and additional fixation techniques in Ogden fractures.

Methods: Two different types of apoepiphyseal tibial tubercle avulsion fractures were created in 40 proximal tibiae according to the modified Ogden classification: (1) Ogden type IIIA and (2) Ogden type IV. The fractures were fixed with either isolated apophyseal screws or additionally with a medial plate or epiphyseal screws. All specimens were biomechanically tested under progressively increasing cyclic loading until failure, while capturing the interfragmentary movements with motion tracking.

Results: Augmentation of apophyseal screw osteosynthesis by a medial plate in Ogden IV fractures or epiphyseal screws in Ogden IIIA fractures exhibited significantly higher cycles to failure and failure loads (P< 0.05), and significantly less axial displacement (P < 0.05) compared to isolated apophyseal screw fixation. Fixation of Ogden type IIIA fractures resulted in significantly less axial displacements and higher construct stiffness, cycles to failure and failure loads compared to Ogden type IV fracture (P < 0.001). Fracture gap opening did not differ significantly between the fixation techniques.

Conclusions: Augmented apophyseal screw fixation of apoepiphyseal tibial tubercle avulsion fractures provides greater biomechanical stability than isolated apophyseal screw fixation. Regardless of fixation technique, Ogden type IV fractures are more unstable than Ogden type IIIA fractures, so an individualized treatment strategy based on fracture morphology is crucial. In case of an Ogden type IIIA or Ogden type IV fracture, surgeons should consider adding epiphyseal screws or a medial plate osteosynthesis to apophyseal screw fixation to best neutralize forces of the extensor mechanism, as long as the often compromised soft tissue envelope can tolerate greater surgical invasiveness.
