RESUMO
Soluble CD163 (sCD163) is a biomarker of macrophage activation, not previously investigated in the circulation of traumatized patients. A biobank of 398 adult trauma patients was analyzed. Patients with an Injury Severity Score (ISS) >8 served as trauma patients (n = 195) and those with ISS ≤8 as trauma controls (n = 203). Serum samples obtained upon admission, 15h and 72h after were analyzed for sCD163 using an in-house ELISA. Multiple linear regression was used to analyze the association between admission levels of sCD163 with, 1: overall trauma severity (ISS), and 2: severity of injury to specified organs using Abbreviated Injury Score (AIS) and Glasgow Coma Scale (GCS). The association between the peak level of sCD163 with 1-year all-cause mortality was analyzed by logistic regression analysis. Median admission levels of sCD163 were higher in trauma patients than trauma controls [2.32 (IQR 1.73 to 2.86) vs. 1.92 (IQR 1.41 to 2.51) mg/L, p < 0.01]. Worsening GCS score was associated with a 10.3% (95% CI: 17.0 to 3.1, p < 0.01) increase in sCD163. Increasing Head-AIS score was associated with a 5.1% (95% CI: -0.5 to 11.0, p = 0.07) increase in sCD163. The remaining AIS scores and ISS were not consistently associated with sCD163 admission levels. Each mg/L increase in sCD163 peak level had an odds ratio 1.34 (95%CI: 0.98 to 1.83), p = 0.06) after adjustment for age, sex, and GCS. Circulating sCD163 is increased in traumatized patients and associated with worsening GCS. Our findings suggest an association between circulating sCD163 levels with 1-year all-cause mortality.
RESUMO
Elevated levels of CNS-derived serum proteins are associated with poor outcome in traumatic brain injury (TBI), but the value of adding acute serum biomarker levels to common clinical outcome predictors lacks evaluation. We analyzed admission serum samples for Total-Tau (T-Tau), Neurofilament light chain (Nfl), Glial fibrillary acidic protein (GFAP), and Ubiquitin C-terminal hydrolase L1 (UCHL1) in a cohort of 396 trauma patients including 240 patients with TBI. We assessed the independent association of biomarkers with 1-year mortality and 6-12 months Glasgow Outcome Scale Extended (GOSE) score, as well as the additive and cumulative value of biomarkers on Glasgow Coma Scale (GCS) and Marshall Score for outcome prediction. Nfl and T-Tau levels were independently associated with outcome (OR: Nfl = 1.65, p = 0.01; T-Tau = 1.99, p < 0.01). Nfl or T-Tau improved outcome prediction by GCS (Wald Chi, Nfl = 6.8-8.8, p < 0.01; T-Tau 7.2-11.3, p < 0.01) and the Marshall score (Wald Chi, Nfl = 16.2-17.5, p < 0.01; T-Tau 8.7-12.4, p < 0.01). Adding T-Tau atop Nfl further improved outcome prediction in majority of tested models (Wald Chi range 3.8-9.4, p ≤ 0.05). Our data suggest that acute levels of serum biomarkers are independently associated with outcome after TBI and add outcome predictive value to commonly used clinical scores.

INTRODUCTION: The STRYKER ADAPT computer-assisted navigation system provides intraoperative feedback to the surgeon regarding implant placement of the Gamma3 nail. The usability of the ADAPT system has not been evaluated. The aim of the study was to investigate the perceived usability of the ADAPT system. MATERIALS AND METHODS: This was a descriptive study with prospectively collected data. ADAPT was introduced at Aarhus University Hospital in February 2021. Prior to introduction, surgeons at the department attended a general introduction to the system. ADAPT was introduced to the surgical nurses and was on display at the surgical ward at more than one occasion, where personal introduction to the system was possible. After introduction, it was mandatory to use ADAPT when using the Gamma3 nail to treat intertrochanteric femur fractures. After each procedure, primary and an eventual supervisor answered a questionnaire, which encompassed the System Usability Scale (SUS) questionnaire. The SUS is a ten-item questionnaire regarding the perceived usability of a system. SUS scores were translated to adjectives, describing user experience on a 7-point adjective scale (worst imaginable, awful, poor, ok, good, excellent, best imaginable). User acceptability, defined as "not acceptable", "marginal" or "acceptable", was also used to interpret the SUS scores. RESULTS: ADAPT was used in 50 procedures by 29 different surgeons, with varying skill-level. Median SUS-score after first-time use of ADAPT for all 29 surgeons was 43 (range: 5-60), which translated to "poor" or "not acceptable". For surgeons who performed ≥ 3 ADAPT-assisted procedures, there were no statistically significant difference in their first to latest SUS-score (median difference: 4.3, p = 0.5). In free text comments ADAPT was positively described as helpful in placement of K-wire and providing educational opportunities for inexperienced surgeons and negatively as inconsistent, slow, time consuming, and causing excessive fluoroscopy. CONCLUSIONS: Usability and acceptability of ADAPT was rated as "poor" or "not acceptable" by the majority of operating surgeons. ADAPT has not been used at our institution based on these findings. The System Usability Scale may be used in further research exploring usability and acceptability of novel computer-assisted navigation systems for orthopaedic surgery.

Intertrochanteric femoral fractures are commonly treated with intramedullary nails (IMNs). A tip-apex distance (TAD) of more than 20-25 mm is associated with an increased risk of cut-out. The Stryker Adaptive Positioning System (ADAPT) is a computer-assisted navigation system designed to reduce TADs. We aim to assess if the ADAPT reduces the number of outliers with a TAD > 20 mm. All patients with intertrochanteric fractures treated with an IMN between 1 September 2020 and 12 March 2022 were included. Patients were included in three periods: a pre-ADAPT period (55 patients); an ADAPT period (50 patients), where it was compulsory to use the system; and a post-ADAPT period after the discontinuation of the system (59 patients). The TADs and lag screw protrusions beyond the lateral cortex were measured. The median TADs in the three periods were 17.0 mm (8-31 mm), 15.5 mm (9-30 mm), and 18.0 mm (11-32 mm), respectively. The absolute number of outliers with a TAD > 20 mm decreased from 15/55 patients in the pre-ADAPT period to 11/50 patients during the ADAPT period. This observation was not statistically significant, but this is likely due to the lack of power of the present study to show changes of this magnitude. However, our expectation that the ADAPT would diminish outliers markedly or close to zero outliers was not met, as we observed 11/50 = 22% outliers with a TAD > 20 mm when using computer-assisted surgery, i.e., ADAPT and Gamma3 for intertrochanteric fractures. Based on these findings, the use of the ADAPT was discontinued at our level 1 trauma center.
RESUMO
Importance: Fractures of the hip have devastating effects on function and quality of life. Intramedullary nails (IMN) are the dominant implant choice for the treatment of trochanteric fractures of the hip. Higher costs of IMNs and inconclusive benefit in comparison with sliding hip screws (SHSs) convey the need for definitive evidence. Objective: To compare 1-year outcomes of patients with trochanteric fractures treated with the IMN vs an SHS. Design, Setting, and Participants: This randomized clinical trial was conducted at 25 international sites across 12 countries. Participants included ambulatory patients aged 18 years and older with low-energy trochanteric (AO Foundation and Orthopaedic Trauma Association [AO/OTA] type 31-A1 or 31-A2) fractures. Patient recruitment occurred between January 2012 and January 2016, and patients were followed up for 52 weeks (primary end point). Follow-up was completed in January 2017. The analysis was performed in July 2018 and confirmed in January 2022. Interventions: Surgical fixation with a Gamma3 IMN or an SHS. Main Outcomes and Measures: The primary outcome was health-related quality of life (HRQOL), measured by the EuroQol-5 Dimension (EQ5D) at 1-year postsurgery. Secondary outcomes included revision surgical procedure, fracture healing, adverse events, patient mobility (measured by the Parker mobility score), and hip function (measured by the Harris hip score). Results: In this randomized clinical trial, 850 patients were randomized (mean [range] age, 78.5 [18-102] years; 549 [64.6% female) with trochanteric fractures to undergo fixation with either the IMN (n = 423) or an SHS (n = 427). A total of 621 patients completed follow-up at 1 year postsurgery (304 treated with the IMN [71.9%], 317 treated with an SHS [74.2%]). There were no significant differences between groups in EQ5D scores (mean difference, 0.02 points; 95% CI, -0.03 to 0.07 points; P = .42). Furthermore, after adjusting for relevant covariables, there were no between-group differences in EQ5D scores (regression coefficient, 0.00; 95% CI, -0.04 to 0.05; P = .81). There were no between-group differences for any secondary outcomes. There were also no significant interactions for fracture stability (ß [SE] , 0.01 [0.05]; P = .82) or previous fracture (ß [SE], 0.01 [0.10]; P = .88) and treatment group. Conclusions and Relevance: This randomized clinical trial found that IMNs for the treatment of trochanteric fractures had similar 1-year outcomes compared with SHSs. These results suggest that the SHS is an acceptable lower-cost alternative for trochanteric fractures of the hip. Trial Registration: ClinicalTrials.gov Identifier: NCT01380444.

Whiplash injuries are common in Denmark affecting around 16,000 new patients annually. Approximately 50% of the casualties develop chronic symptoms and 10% become disabled. Many of these patients will have contact to the healthcare system, and there is a need for structured and knowledge-based examination, diagnosis and recording of findings in all clinical settings. This review discusses which variables should be recorded in clinical practice, in order to establish the best possible foundation for a structured individualized treatment protocol of the whiplash patient.

Trauma-induced coagulopathy (TIC) is a risk factor for death and is associated with deviations in thrombin generation. TIC prevalence and thrombin levels increase with age. We assayed in vivo and ex vivo thrombin generation in injured patients (n = 418) to specifically investigate how age impacts thrombin generation in trauma and to address the prognostic ability of thrombin generation. Biomarkers of thrombin generation were elevated in young (< 40 years) and older (≥ 40 years) trauma patients. In vivo thrombin generation was associated with Injury Severity Score (ISS) and this association was stronger in young than older patients. In vivo thrombin generation decreased faster after trauma in the young than the older patients. Across age groups, in vivo thrombin generation separated patients dying/surviving within 30 days at a level comparable to the ISS score (AUC 0.80 vs. 0.82, p > 0.76). In vivo and ex vivo thrombin generation also predicted development of thromboembolic events within the first 30 days after the trauma (AUC 0.70-0.84). In conclusion, younger trauma patients mount a stronger and more dynamic in vivo thrombin response than older patients. Across age groups, in vivo thrombin generation has a strong ability to predict death and/or thromboembolic events 30 days after injury.

Preoperative planning in orthopaedic fracture surgery corroborates with the goal of establishing the best possible surgical result and ensuring a functioning limb for the patient. From placing sketches on overhead projector paper and measuring lengths from anatomical landmarks, ways of preoperative planning have evolved rapidly over the last 100 years. Today, preoperative planning includes methods such as advanced 3-Dimensional (3D) printed models and software programs incorporating entire libraries of osteosynthesis materials that can be shaped and rotated to fit a patient's specific anatomy. Relevant literature was evaluated to review the development of preoperative templating from the past and present, in order to assess its impact on the future of osteosynthesis.We identified studies on 3D-imaging, computer-assisted systems, and 3D-printed fractured bones and drill guides. The use of some of these systems resulted in a reduction in operation time, blood loss, perioperative fluoroscopy and hospital stay, as well as better placement of osteosynthesis material. Only few studies have identified differences in patient morbidity and mortality. Future techniques of preoperative templating are on the rise and the potential is vast. The cost-effectiveness and usefulness of certain methods need to be evaluated further, but the benefit of preoperative templating has the potential of being revolutionary, with the possibility of radical advances within orthopaedic surgery.

This study examined the association between interpersonal violence and a range of psychiatric and physical health outcomes and assessed whether these associations changed when controlling for a stress-related diagnosis. An observational case-control study was conducted on a sample of 4,059 victims of violence. Using propensity score matching a number of risk factors (assessed five years prior assault) were used. Controls were matched 10:1 using the Danish Central Registry System. Outcomes were ICD-10 diagnoses of a range of psychiatric and physical health outcomes in the 15 years post-injury. Statistically significant associations were found for all psychiatric conditions and a diagnosis of a drug or substance misuse disorder. These findings remained even after controlling for a diagnosis of a stress-related disorder. Large scale case-control studies using the Danish nationwide registers enables a powerful way of assessing the relative impact of exposure to interpersonal violence on the development of psychiatric and physical health problems.

In fracture surgery, large bone defects and non-unions often require bone transplantation, and alternatives to autograft bone substitutes in the form of allografts from bone banks and the derivate demineralised bone matrix (DBM) are widely used. With a focus on efficacy, clinical evidence, safety, cost, and patient acceptance, this review evaluated the difference between allogeneic allograft or DBM as a bone substitute in trauma surgery. The efficacy in supporting bone healing from allograft and DBM is highly influenced by donor characteristics and graft processing. Mechanical stability is achieved from a structural graft. Based on the existing literature it is difficult to identify where DBM is useful in trauma surgery, and the level of evidence for the relevant use of allograft bone in trauma is low. The risk of transmitting diseases is negligible, and the lowest risk is from DBM due to the extensive processing procedures. A cost comparison showed that DBM is significantly more expensive. The experiences of dental patients have shown that many patients do not want to receive allografts as a bone substitute. It is not possible to definitively conclude whether it makes a difference if allograft or DBM is used in trauma surgery. It is ultimately the surgeon's individual choice, but this article may be useful in providing considerations before a decision is made.

INTRODUCTION: Penetrating thoracic trauma presents a rare and serious condition with great diversity in impalement mechanisms and following injuries, resulting in a high mortality. This case reports successful management of a severe thoracic trauma and need for collaboration between surgical specialties. PRESENTATION OF CASE: An 18-year-old, otherwise healthy, Caucasian female had penetration of the chest with a wooden post due to a solo car accident and was admitted to a Level 1 trauma center at a university hospital. Trauma computed tomography scan showed costa fractures and fracture of the left clavicular bone. Damage to the subclavian artery, the brachial plexus and pulmonary artery were suspected. Extracorporeal circulation was on standby at surgery. However, removal of the foreign object did not result in any major bleeding. The patient was discharged from hospital on the 19th day after surgery. Fifteen months after the trauma, surgery was performed to remove the first two costae on the left side, as a disfiguring prominence on the neck was the patients' only complaint. DISCUSSION: Initial management of the patient should follow ATLS® principles with stabilization of airways, breathing and circulation. Multidisciplinary approach resulted in reconstruction of vessels, debridement and wound closure. The importance of follow-up after trauma and surgery are underlined by the current case, as the patient required additional surgery at follow up. CONCLUSION: Multidisciplinary approach to the current penetrating trauma resulted in rapid assessment of injuries and management with excellent outcome.
RESUMO
This case report illustrates a common clinical issue, where an 86-year-old woman was being referred to an emergency department because of severe hip and groin pain. The primary examination ruled out proximal femoral or pelvic fracture, and after an MRI was performed, the unusual cause of her pain was revealed: a rupture of the iliopsoas tendon at its insertion on the lesser trochanter. We present the causes and dispositions for iliopsoas tendon rupture among elderly, as well as the diagnostic order of imaging techniques and treatment for this condition.

INTRODUCTION: Undisplaced femoral neck fractures (FNFs) are usually treated by internal fixation (IF) but two randomised controlled trials (RCTs) have demonstrated advantages of treatment with arthroplasty. The complication rate was lowered but there were no clinically improved patient-reported outcome measures (PROM), which could be due to underpowering or choice of selected PROM as the studies do appear to report a better functional outcome. We will conduct an RCT comparing IF with arthroplasties in patients aged over 65 years with an undisplaced FNF. METHODS AND ANALYSIS: All hospitals in Denmark treating patients with hip fracture can provide patients for this study; therefore, the study can be considered a national RCT. Patients over 65 years old with an undisplaced FNF will be screened for eligibility and patients will only be excluded if they are unable to understand the study information (due to dementia or language), if they have a posterior tilt >20°, a pathological fracture or they cannot walk. Participants will be electronically randomised (in alternating blocks of 4 or 6) into either IF or arthroplasty. Postoperative care will follow the department standards.Primary and secondary outcomes and measuring points have been established in collaboration with patients with hip fracture by focus group interviews. The primary outcome measure is the New Mobility Score assessed after 1 year. Secondary outcomes are the Oxford Hip Score, EuroQol 5 domain (EQ-5D-5L), degree of posterior tilt, pain Verbal Rating Scale, reoperation and mortality. ETHICS AND DISSEMINATION: The study is approved by the Danish Data Protection Agency (19/7429) and the scientific ethics committee (S-20180036). All participants will sign an informed consent before entering the trial. Because this is a national trial, all relevant healthcare professionals in Denmark will automatically receive the trial results that will be published in international peer-reviewed journals. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT04075461).

INTRODUCTION: This study sought to expand the very limited data on Scandinavian paediatric poly-trauma patients by charactering patients from this population admitted to a Danish level-1 trauma centre. METHODS: This retrospective cohort study included all patients 15 years or younger who were admitted to the trauma centre at Aarhus University Hospital, Denmark from January 2000 to May 2014. Injury severity was calculated using the Injury Severity Score (ISS). The Wilcoxon rank-sum test was used to determine significant differences between sexes. RESULTS: A total of 880 children (499 boys and 391 girls) were included. No significant sex-related differences were observed in the numbers admitted during the study period, age at admission or severity of injuries. Overall, 30% of the paediatric patients were admitted in the afternoon (3-6 p.m.). The crude death rate was 2.7% of all admissions. Traffic accidents accounted for 48% of all admissions and two-thirds of all deaths. All non-survivors received ISSs of 16 or higher, and 20% of deaths in this group and 42% of overall deaths occurred within the first 24 hours. CONCLUSIONS: Our study suggests that in Denmark, children admitted to a trauma centre are most likely to have been injured in traffic accidents and/or in the afternoon. Deaths were few and limited to the severely injured children; many survived despite severe injuries. FUNDING: none. TRIAL REGISTRATION: not relevant.

Since the 1990s, there has been a reduction in the homicide rate in Denmark and other Western countries. Our hypothesis is that part of the decrease in the sharp force homicide rate can be explained by better and faster medical treatment over time, and we explore this via stab wound homicides, the largest group of homicides in Denmark. To investigate our hypothesis we undertook an epidemiological study of 428 stab wound homicides in Denmark 1992-2016 based on autopsy reports with registration of stab wounds, quantification of injury severity, treatment intensity and survival time. During 1992-2016, there was a significant reduction in the annual number of victims with a single stab wound, but no reduction in victims with multiple stab wounds. Victims with single stab wounds reached the hospital more often, survived longer and had less severe injuries (New Injury Severity Score (NISS)) than victims with multiple stab wounds. Higher NISS correlated with shorter survival time for all the stab wound victims and for the subgroup that underwent medical treatment. During the 25-year study period, the proportion of victims who underwent surgery before dying increased threefold. The victims in the first half of the study period had shorter survival times than the victims in the last half. We concluded that better and faster medical treatment could partly be responsible for the observed decrease in the number of single stab wound homicides and thereby possibly also in the total number of stab wound homicides.

Patients with hip fractures are typically elderly individuals with several co-morbidities. Upon admission to the hospital, they often present with acute pain, electrolyte disturbances, anaemia, coagulopathy, and delirium. Long waiting times for surgery are associated with increased morbidity and mortality. The balance between the number of clinical tests and optimisation, which may (i.e., fewer complications and better survival) or may not (i.e., more complications and increased mortality due to unnecessary surgical delay) benefit the patient, has been a preoperative challenge. This summary will review existing clinical guidelines and relevant selected studies to evaluate the extent of preoperative optimisation needed prior to hip fracture surgery.

Sharp force trauma is a common homicide method. The weapon is typically a knife, which is easily accessible and does not require special skills. We have analyzed all 471 sharp force homicides in Denmark during 1992-2016 with special focus on aspects that are relevant to forensic pathologists, including the distribution of wounds and organ injuries. Most homicides were committed inside with a kitchen knife. The front left thorax was the most common area to be affected by sharp force trauma. In 18.9% of the victims, there was only one sharp injury, the majority on the thorax. The most common trajectory for stab wounds was directly posterior with no deviation to the sides or up/down followed by directly anterior. The heart (including pericardium) and lungs (including hemo- and pneumothorax) had injuries in more than 75% of the victims. 67% of victims were males. Female victims had more sharp force injuries and defense wounds than male victims. Most females were killed in domestic homicides (73.7%), most commonly in partner killings (56.4%). In contrast, many male victims were killed in a setting of nightlife/intoxication (34.0%) most by a friend/acquaintance delivering a few stab wounds. The results clearly show strong sex differences in both victims and offenders. This could be useful for shaping policies and public opinion, and as a route for understanding the developments in interpersonal violence. In the narrow setting of death investigation, our results will provide an evidence-based approach to understanding the injury patterns in sharp force homicide.

Background: Interpersonal violence is a pervasive global public health problem associated with myriad health, social and economic consequences. In recent years the rates of interpersonal violence have decreased, however, high numbers of individuals continue to present to emergency departments for non-fatal violence-related injuries. Objective: This study aimed to examine a range of risk factors associated with violence-related injuries in an emergency department in Denmark. Method: A case-control study was conducted on a sample of 3,940 victims of violence collected by the Accident Analysis Center for Aarhus County Municipality. Using the Danish Civil Registry System, controls were matched 10:1 on age, gender and municipality. Risk factors were rendered from Danish health and social registers five years prior to the violent assault. These included marital status, educational qualification, employment status, national origin, involvement with child protective services (CPS), prior convictions, and a diagnosis of adjustment disorder and alcohol and/or substance use disorders. Results: Multivariate logistic regression identified that being male, divorced, unmarried, non-Danish origin, attending compulsory education, being outside the labour force, students, involvement with CPS, prior criminal conviction and a diagnosis of alcohol and/or substance use disorders were associated with an increased likelihood of being exposed to violence. The dominant risk factors were alcohol and/or substance use disorders (OR = 3.62) and prior criminal conviction (OR = 3.54). Attainment of tertiary education was associated with a reduced likelihood of being a victim of violence. Conclusion: These findings highlight that research into effective interventions offered in emergency departments may help the public health effort to reduce the health, social and economic burden of interpersonal violence.
Antecedentes: la violencia interpersonal es un problema generalizado de salud pública mundial asociado con innumerables consecuencias sanitarias, sociales y económicas. En los últimos años, las tasas de violencia interpersonal han disminuido, sin embargo, un gran número de personas continúan presentándose en los servicios de urgencias por lesiones relacionadas con la violencia no mortal.Objetivo: este estudio tuvo como objetivo examinar una serie de factores de riesgo asociados con lesiones relacionadas con violencia en un servicio de emergencias en Dinamarca.Método: se realizó un estudio de casos y controles en una muestra de 3,940 víctimas de violencia recolectadas por el Centro de Análisis de Accidentes del Municipio del Condado de Aarhus. Usando el Sistema de Registro Civil Danés, los controles fueron pareados 10: 1 en edad, género y municipio. Los factores de riesgo provinieron de los registros sociales y de salud daneses cinco años antes del ataque violento. Estos incluían estado civil, calificación educativa, estado laboral, origen nacional, participación en los servicios de protección infantil (CPS), condenas anteriores y un diagnóstico de trastorno de adaptación y trastorno por abuso de sustancias.Resultados: La regresión logística multivariada identificó que ser hombre, divorciado, no casado, de origen no danés, asistir a la educación obligatoria y no tener empleo, educación o capacitación, ser estudiante, participación en el CPS, condena criminal previa y diagnóstico de un trastorno por abuso de sustancias estaban asociados con mayor probabilidad de ser expuesto a violencia. Los factores de riesgo dominantes fueron un trastorno por abuso de sustancias (OR = 3,62) y una condena penal previa (OR = 3,54). El logro de la educación terciaria se asoció con una menor probabilidad de ser víctima de violencia.Conclusión: estos hallazgos resaltan que la investigación sobre intervenciones efectivas ofrecidas en los departamentos de emergencia puede ayudar al esfuerzo de salud pública para reducir la carga sanitaria, social y económica de la violencia interpersonal.
RESUMO
Patients suffering a low-energy fracture are at high risk of subsequent fractures. Investigation of all fragility fracture patients above the age of 50 years is recommended in order to prevent further fractures. The aim of this study was to investigate alternative strategies including known risk factors (age, sex, and body weight) for selecting fracture patients for osteoporosis assessment and investigate how these strategies would affect the proportion of patients with osteoporosis identified and the number of patients referred for Dual X-ray Absorptiometry (DXA) compared with the original FLS strategy. From OFELIA; a cohort study comprising 794 fragility fracture patients we included 622 patients aged 18 + years (mean age 56 ± 17) with fragility fractures. We investigated the predictive value of clinical risk factors using ROC curves and AUC analyses. The revised strategies were compared by analyzing sensitivity and specificity of different strategies based on sex, age, BMI, and bodyweight. For patients 50 + years, a strategy investigating men and women with body weight ≤ 85 kg resulted in sensitivity and specificity of 94% and 25%, respectively, reducing the number of DXAs by 21%. For patients < 50 years, the prevalence of osteoporosis was low and it was, therefore, difficult to develop an acceptable strategy. We found that the original FLS strategy can be modified to include substantially fewer patients and still only miss the osteoporosis diagnosis in a very few patients. A modified strategy would potentially save costs and concerns in many patients.
