Burden Of Fractures Research Articles

Prediction of hip fracture by high-resolution peripheral quantitative computed tomography in older Swedish women.

The socioeconomic burden of hip fractures, the most severe osteoporotic fracture outcome, is increasing and the current clinical risk assessment lacks sensitivity. This study aimed to develop a method for improved prediction of hip fracture by incorporating measurements of bone microstructure and composition derived from high-resolution peripheral quantitative computed tomography (HR-pQCT). In a prospective cohort study of 3028 community-dwelling women aged 75 to 80, all participants answered questionnaires and underwent baseline examinations of anthropometrics and bone by dual x-ray absorptiometry (DXA) and HR-pQCT. Medical records, a regional x-ray archive, and registers were used to identify incident fractures and death. Prediction models for hip, major osteoporotic fracture (MOF), and any fracture were developed using Cox proportional hazards regression and machine learning algorithms (neural network, random forest, ensemble, and XGBoost). In the 2856 (94.3%) women with complete HR-pQCT data at 2 tibia sites (distal and ultra-distal), the median follow-up period was 8.0years, and 217 hip, 746 MOF, and 1008 any type of incident fracture occurred. In Cox regression models adjusted for age, BMI, clinical risk factors (CRF), and femoral neck bone mineral density (FN BMD) the strongest predictors of hip fracture were tibia total volumetric BMD and cortical thickness. The performance of the Cox regression-based prediction models for hip fracture was significantly improved by HR-pQCT (time-dependent AUC; area under receiver operating characteristic curve at 5years of follow-up 0.75 [0.64-0.85]), compared to a reference model including CRFs and FN BMD (AUC = 0.71 [0.58-0.81], p<.001) and a FRAX risk score model (AUC = 0.70 [0.60-0.80], p<.001). The Cox regression model for hip fracture had a significantly higher accuracy than the neural network-based model, the best-performing machine learning algorithm, at clinically relevant sensitivity levels. We conclude that the addition of HR-pQCT parameters improves the prediction of hip fractures in a cohort of older Swedish women.

Fracture liaison service (FLS) is associated with lower subsequent fragility fracture risk and mortality: NoFRACT (the Norwegian capture the fracture initiative).

Efficient fracture prevention strategies are warranted to control the global fracture burden. We investigated the effect of a standardized fracture liaison service (FLS) intervention on subsequent fracture risk and mortality. The NoFRACT study was designed as a multicenter, pragmatic, register-supported, stepped-wedge cluster-randomized trial. The FLS intervention was introduced in three clusters with 4-month intervals starting May 2015 through December 2018 and included evaluation of osteoporosis and treatment in patients over 50years with a low-energy fracture. Based on data from the Norwegian Patient Registry, patients with index fractures were assigned to the control period (2011-2015) or intervention period (2015-2018) depending on the time of fracture. Rates of subsequent fragility fractures (distal forearm, proximal humerus, or hip) and all-cause mortality were calculated. A total of 100,198 patients (mean age 69.6years) suffered an index fracture of any type. During a maximum follow-up of 4.7years, 11% (6948) of the women and 6% (2014) of the men experienced a subsequent fragility fracture, and 20% (14,324) of the women and 22% (8,326) of the men died. FLS was associated with 13% lower subsequent fragility fracture risk in women (hazard ratio (HR) 0.87, 95% confidence intervals (CI) 0.83-0.92) and 10% in men (HR 0.90, 95% CI 0.81-0.99) and 18% lower mortality in women (HR 0.82, 95% CI 0.79-0.86) and 15% in men (HR 0.85, 95% CI 0.81-0.89). A standardized FLS intervention was associated with a lower risk of subsequent fragility fractures and mortality and may contribute to reduce the global fracture burden.

Cost and Inpatient Burden of Mandible Fracture Management: A 14-Year Analysis.

To evaluate characteristics associated with increased cost and length of hospitalization of mandible fracture management. Retrospective chart review. Demographics, injury mechanism, associated injuries, treatment information, and associated costs were collected for all patients treated for mandible fracture treated at a single institution over a 14-year period. Univariable and multivariable analyses were performed to identify the patient and fracture characteristics associated with increased cost and length of hospitalization. We identified 552 patients with 834 mandible fractures from 2008 to 2022. Patients' mean age was 40 years, 67% were male, and 38% Caucasian. The median cost of treatment, adjusted for inflation, was $8,869.49, and median length of stay (LOS) was 3.0 days. Associated cranial/intracranial injury, transfer presentation, increased facial fractures, and traffic-related injuries resulted in a significant increase in both cost and LOS. LOS had a significant impact on cost, while age also significantly increased LOS for patients with mandible fractures. This study represents one of the largest comprehensive databases of mandible fractures and one of the first to provide a descriptive cost and inpatient burden analysis of mandible fracture management. To improve outcomes and reduce hospital cost and inpatient burden, protocols should be implemented to identify and mitigate factors that we identified as contributing to increased cost and length of hospitalization. This study represents one of the largest reviews of cost and inpatient burden of mandible fractures. We found that presentation via transfer, traffic-related injuries, and more facial fractures were associated with significantly higher cost and longer length of hospitalization. 4 Laryngoscope, 2024.

Management of Osteoporosis in Parkinson's Disease: A Systematic Review of Clinical Practice Guidelines.

Parkinson's disease (PD) is the fastest-growing neurological disorder globally. Defining features include tremor, muscular rigidity, bradykinesia, and postural instability, which in combination with nonmotor symptoms such as cognitive impairment and orthostatic hypotension increase the risk of falls. Along with low bone mineral density, fracture risk is high in PD. The aims were to identify and appraise clinical practice guidelines, consensus statements, and treatment algorithms containing recommendations for bone health in people with PD (PwP). We systematically searched 4 electroninc databases (MEDLINE, Embase, Emcare, and Web of Science) (n = 78), in addition to the websites of organizations, societies, and professional bodies focused on PD or osteoporosis (n = 28), up to April 22, 2024. After duplicate removal, screening, and full-text review, 6 records were included. Included records were appraised using the AGREE II (Appraisal of Guidelines for Research and Evaluation) tool. All records recognized bone health as a concern in PD, yet recommendations for fracture-risk screening were inconsistent. Two of six records grouped PD under the broad category of neurological diseases. The acceptability and tolerance of anti-osteoporosis medications in PwP was discussed only in 1 record, which incorporated national osteoporosis guidelines into a PD-specific treatment algorithm. This review highlights that despite the documented high fracture rates of PwP, health professionals do not always have adequate resources to support them when considering how to manage osteoporosis. Osteoporosis screening and management needs to be incorporated into PD treatment guidelines, and equally providing specific recommendations for PwP related to bone health in national osteoporosis guidelines should be a priority given the high burden of fracture in the patient population.

Falls prevention in older adults: How can primary care pave the way?

Primary care sees a large proportion of older adults experiencing or at risk of falls, providing an important opportunity for falls prevention. Falls can result in significant burden of fractures, hospitalisation and mortality and they have high associated healthcare costs. A third of falls could be prevented through use of evidence-based interventions. This article will present up-to-date evidence in falls prevention from the latest global guidance and experts in the field. It will provide an overview of how to assess the likelihood of an individual experiencing falls in the future, provide guidance on signposting and referral to appropriate services. In current primary care practice, with significant time pressure and conflicting priorities, this article aims to focus our attention and provide a practical approach to prevention of falls in the community.

Estimated frequency and economic burden of incident fragility fractures during 2023 in Mexico

SummaryEpidemiologic and economic data regarding osteoporotic fractures in Mexico is scarce and mostly outdated. Through a model, we estimated the incidence and costs of osteoporotic fractures in adults ≥ 50 years old in Mexico during the year 2023. Results showed that these events are both frequent and costly, leading to a considerable economic impact.PurposeOsteoporosis and its fractures impose a high clinical and economic burden. The objective of this analysis was to estimate the frequency and costs owing to incident fragility fractures (FFs) during the year 2023 in Mexico.MethodsThis is an incidence-based cost-of-illness study. The target population is adults ≥ 50 years old sustaining a fracture related to osteoporosis (caused by a fall on the same level). The model estimates the costs and productivity losses associated with their treatment within 1 year post-fracture. National epidemiologic databases supplemented with information, derived from literature when appropriate, were used to estimate the frequency of new FFs during 2023 in the study population. Resource use included surgical and non-surgical inpatient or ambulatory care the patients received immediately after fracture plus the outpatient physiotherapy post-discharge and the eventual follow-up with a specialist who may prescribe pharmacotherapy. Sick days taken in employed patients were estimated from the literature. Local unitary costs of services and drugs for both public and private settings as well as average income in those occupied were applied. All costs are reported in Mexican pesos (MXN) from 2023.ResultsThe model estimated a total of 229,239 FFs, among which 63% were classified as a major osteoporotic fracture, including 53,842 and 41,459 fractures located at the hip and vertebral, respectively. The total costs were estimated at 15,593 million MXN; most of them (75.2%) were attributable to acute-phase care.ConclusionsFragility fractures represent a serious health problem for Mexico. Better preventive/therapeutic strategies may help to mitigate their significant financial toll.

Prevalence and Risk Factors of Hip Fracture at Tertiary Hospital in Mogadishu, Somalia.

This study aims to determine the frequency of hip fractures and associated risk factors among patients receiving care at the Somalia Turkish Training and Research Hospital in Mogadishu. A retrospective study of patients treated at the Somalia Turkish Training and Research Hospital in Mogadishu was carried out. 96 of the 108 patients who were admitted met the inclusion criteria. Analyzing the medical records of individuals diagnosed with hip fractures between January and December 2023 allowed for the collection of data on demographics, hip fracture type, and medical history and also conducted follow-ups to identify other potential contributing factors that may not be available in medical records. The main conclusions have been established using descriptive statistical analysis. About 8.67% of all fracture cases were hip fractures, Elderly people (60+) represented the largest group at 64.6%, followed by younger people (17-39) and Middle-aged people (40-59) at 15.6%, and children (3-16) at 4.2%. Females comprised 56.3% of cases, while males made up 43.8%. Most patients (78.1%) had low physical activity. Falls were the primary cause of fractures (83.3%), followed by other traumas (13.5%), and pathological fractures (7.3%). 32.3% of patients had comorbidities, 8.3% had a family history, and 22.9% had prior fractures. The most prevalent hip fractures (81.3%) were those of the femur neck, followed by subtrochanteric and intertrochanteric fractures (10.4% and 8.3%, respectively). This study emphasizes the frequency of hip fractures in Mogadishu, Somalia, as well as the significance of fall prevention, age, gender, and comorbidity treatment. We suggest comprehensive risk assessments, gender-specific bone health programs, fall prevention programs, focused prevention for the elderly, and public education campaigns to reduce the burden of hip fractures and encourage healthier people in our community by putting these measures into practice.

6577 National Trends in Fragility Hip Fractures Among Community Dwelling Women With Low Femoral Neck Bone Mineral Density

Abstract Disclosure: A. Atri: None. C. Anastasopoulou: None. Introduction: Fragility hip fractures are a major public health burden and are considered a good measure of the quality of healthcare. However, contemporary trends in fragility hip fractures in women with low femoral neck bone mineral density (BMD) in the United States are not known. Methods: We used data from the National Health and Nutrition Examination Survey (NHANES) for the years 2009-10, 2013–14 and 2017–18 to include U.S. women aged ≥ 60 years with bone mineral density (BMD) T score ≤ -1 at the femur neck, which was measured by dual energy x-ray absorptiometry (DEXA) on Hologic Discovery Model A Densitometers (Hologic, Inc., Bedford, Massachusetts). Fragility fracture at the hip was defined as self-reported hip fracture resulting from a fall from standing height or less. Participants with missing BMD and fracture data were excluded. ANOVA was used for comparing means. The Cochran-Armitage test was utilized for trend analysis. Results: Overall, in women aged ≥ 60 years with femoral neck T score ≤ -1, the average age of women of low BMD decreased from 71(±7.2) years to 69.6 (±6.7) years, whereas the mean T-score modestly worsened from – 1.96 (±0.62) to -2.04 (±0.77) from 2009-10 to 2017-18. Similarly, the prevalence of women with T score ≤ -2.5 increased from 18.1% to 21.3%. We also found no significant change in proportion of women who reported treatment for osteoporosis (2009-10: 19.8%, 2013-14: 18.5%, 2017-18: 19.7%; p trend = 0.052). However, proportion of women who experienced fragility hip fractures decreased significantly (2009-10: 2.4%, 2013-14: 1.5%, 2017-18: 1.2%; p trend = 0.001). The mean age of index fragility hip fracture was 70.6 years in 2009-10, 68.3 years in 2013-14 and 71.7 years in 2017-18 (p = 0.001). Age stratified analysis showed a decreasing trend in proportion of women ≥ 80 years who experienced their index fragility hip fracture (2009-10: 25.9%, 2013-14: 14.7%, 2017-18: 15%; p trend = 0.001) and 70-79 years (2009-10: 40.9%, 2013-14: 21.1%, 2017-18: 35.8%; p trend = 0.001), while an increasing trend was seen in women 60–69 years (2009-10: 33.2%, 2013-14: 64.2%, 2017-18: 49.2%; p trend = 0.001). Discussion In this nationally representative cohort of community-dwelling US women with a low femoral neck BMD, we found a 50% decrease in burden of fragility hip fractures over a 10-year period from 2009-10 to 2017-18. This trend was observed despite worsening mean femoral neck T-scores, T score ≤ -2.5, and similar rates of osteoporosis treatment. Interestingly, the proportion of women who experienced their index fragility hip fracture showed a declining trend among the 70-79 years and ≥ 80 years age-groups. This change may be due to increasing awareness and utilization of measures to decrease falls such as exercise, nutrition, health education and environment modifications targeted towards the elderly population.

Lower Limb Comprehensive Reconstructive Surgery: Experiences from an Orthopedic Teaching Unit

Abstract Introduction: The burden of open extremity fractures is well recognized in placing a burgeoning demand on an already exhausted medical facility in low- and middle-income countries. This study aims to evaluate the functional outcome following “orthoplastic management” by orthopedic surgeons trained in limb reconstruction surgery. Methodology: Adult patients with open lower limb injuries treated from January 1, 2022, to December 30, 2022, who underwent single or staged fixation and reconstruction procedures were identified. Patients with Gustilo–Anderson type IIIB fractures requiring skeletal stabilization with soft-tissue cover were included. Polytrauma patients requiring multidisciplinary surgical attention were excluded. A team of orthopedic surgeons trained in limb reconstruction was involved in the management. Inpatient and outpatient department follow-up by the treating team was done to document complications (infections, reoperations, and graft failures) and functional outcomes using the Lower Extremity Function Score. The duration of mean follow-up was 1 year since index surgery. Results: A total of 24 adult patients with open lower limb injuries with preoperative Ganga Hospital Score (GHS) were included. Decision toward fixation with primary closure or further reconstruction was made collectively. The gray zone (GHS score of 15–16) of patients was more aggressively managed with emphasis on salvage. Additional reconstructive procedures were carried out based on the assessment at consequent follow-up. Three patients had a suboptimal joint function (less than functional range of motion for the involved joint) due to the resultant loss of compartment(s) and joint contracture. Five patients were retaken to the theater for further supplementary or corrective procedures following the index, definitive surgical procedure (bone grafting, partial flap loss, and fixator readjustment). Conclusion: Good-to-excellent functional outcome was demonstrated with the “orthoplastic approach” where skeletal stabilization as well as soft-tissue reconstruction was performed by trained orthopedic surgeons. This study demonstrated that orthoplastic surgery is a safe and effective method of limb salvage.

High bone fracture risk in a large modern cohort of liver transplant recipients

Liver transplantation (LT) has historically been associated with a high prevalence of osteoporosis, but most of the available data date back to late 1990s–early 2000s with limited sample size. Our aim was to assess the prevalence of bone fragility fractures and contributing factors in a large modern cohort of liver transplant recipients. Retrospective study of 429 consecutive patients receiving liver transplantation from 1/1/2010 to 31/12/2015. Final cohort included 366 patients. Electronic radiological images (lateral views of spine X-rays or Scout CT abdominal scans) performed within 6 months from LT, were blinded reviewed to screen for morphometric vertebral fractures. Symptomatic clinical fragility fractures were recorded from the medical records. Patients with fragility fractures in the cohort were 155/366 (42.3%), with no significant differences between sexes. Most sustained vertebral fractures (145/155, 93.5%), mild or moderate wedges, with severe fractures more frequently observed in women. Multiple vertebral fractures were common (41.3%). Fracture rates were similar across different etiologies of cirrhosis and independent of diabetes or glucocorticoids exposure. Kidney function was significantly worse in women with fractures. Independently of age, sex, alcohol use, eGFR, and etiology of liver disease, low BMI was significantly associated with an increased risk for fractures (adjusted OR 1.058, 95%CI 1.001–1.118, P = 0.046). Our study shows a considerable fracture burden in a large and modern cohort of liver transplant recipients. Given the very high prevalence of bone fractures, a metabolic bone disease screening should be implemented in patients awaiting liver transplantation.

Global and regional estimates of hip fracture burden associated with type 1 diabetes from 1990 to 2021.

To assess the global and regional burden of hip fractures associated with type 1 diabetes (T1D) from 1990 to 2021. The population attributable fraction was calculated by combining the published risk ratio with T1D prevalence (age ≥ 20 years) from the Global Burden of Disease study to estimate the T1D-associated hip-fracture burden. Trends were assessed using the age-standardized incidence rate (ASIR) and estimated annual percentage change (EAPC). The global incidence of T1D-related hip fractures was 290 180 in 2021 with an ASIR of 3.96 (95% confidence interval: 1.92-5.87) per 100 000 population and a male-to-female ratio of 0.54. At the super-regional level, the highest incidence (204 610) and ASIR (13.09 per 100 000 population; 6.40-25.53) were observed in high-income regions, in particular in Australasia and Western Europe. Notably, Australasia exhibited the highest EAPC, 2.90% in T1D-associated ASIR, followed by East Asia (2.73%). The incidence among those aged 45-64 years grew significantly in 14 regions over the past decade. Nationally, the ASIR increased in 166 countries from 1990 to 2021. High-income regions experienced the greatest burden of T1D-associated hip fracture, while Australasia and East Asia witnessed the largest increase over the last 32 years. Prioritizing the promotion of T1D treatment and hip-fracture screening for middle-aged females living with T1D is crucial in these regions.

Multidisciplinary team approach for CKD-associated osteoporosis.

Chronic kidney disease-mineral and bone disorder (CKD-MBD) contributes substantially to the burden of cardiovascular disease and fractures in patients with CKD. An increasing arsenal of diagnostic tools, including bone turnover markers and bone imaging, is available to support clinicians in the management of CKD-associated osteoporosis. Although not mandatory, a bone biopsy remains useful in the diagnostic workup of complex cases. In this special report, the European Renal Osteodystrophy (EUROD) initiative introduces the concept of a kidney-bone multidisciplinary team (MDT) for the diagnosis and clinical management of challenging cases of CKD-associated osteoporosis. In 2021, the EUROD initiative launched virtual clinical-pathological case conferences to discuss challenging cases of patients with CKD-associated osteoporosis, in whom a bone biopsy was useful in the diagnostic workup. Out of these, we selected four representative cases and asked a kidney-bone MDT consisting of a nephrologist, an endocrinologist and a rheumatologist to provide comments on the diagnostic and therapeutic choices. These cases covered a broad spectrum of CKD-associated osteoporosis, including bone fracture in CKD G5D, post-transplant bone disease, disturbed bone mineralization, severely suppressed bone turnover and severe hyperparathyroidism. Comments from the MDT were, in most cases, complementary to each other and additive to the presented approach in the cases. The MDT approach may thus set the stage for improved diagnostics and tailored therapies in the field of CKD-associated osteoporosis. We demonstrate the clinical utility of a kidney-bone MDT for the management of patients with CKD-MBD and recommend their establishment at local, national, and international levels.

Global burden of fracture of sternum and/or ribs: An analysis of 204 countries and territories between 1990 and 2019

Sternum and rib fractures represent a significant global health concern, contributing to morbidity and disability on a worldwide scale. However, there is a notable lack of recent epidemiological data detailing the global and regional burden of these fractures. We undertook a systematic analysis of the prevalence of sternum and rib fractures at the global, regional, and national levels in 2019, while also examining time trends spanning from 1990 to 2019. To achieve this, we extracted data from the Global Burden of Disease Study 2019, enabling us to determine incidence, prevalence, years lived with disability (YLDs), and their corresponding age-standardized rates. In 2019, there were 4.1 million incident cases and 2 million prevalent cases of sternum and rib fractures worldwide. These figures represent increases of 43.7 % and 64.1 %, respectively, since 1990. YLDs also exhibited a notable increase, rising by 62.4 % to reach 190,834 cases. However, since 1990, their equivalent age-standardized rates, which ranged from 5.5 % to 7.1 %, have decreased. Notably, China had the greatest incidence (1.2 million cases), prevalence (573,000 cases), and number of YLDs (55,400 cases), all in 2019. The greatest age-standardized incidence rate (143/100,000) and age-standardized prevalence rate (65/100,000) were both recorded in Greenland in the same year. It's critical to emphasize that men experience these fractures at considerably higher rates than women. Around 70 % of incident instances included unintentional injuries worldwide and across all regions. High-socioeconomic regions had the highest rates of incidence, prevalence, and YLDs, albeit these rates have declined by 6.4 % to 7.1 % since 1990, whereas low-middle and low-income areas have had rises. This study, which spans the years 1990 to 2019, provides a thorough and current assessment of the global burden attributed to sternum and rib fractures. In terms of nations, regions, sociodemographic index (SDI) levels, age groups, genders, and reasons, it reveals significant variances and trends. The knowledge obtained from this study can be extremely useful in formulating health policy, allocating resources, and developing methods to prevent these injuries.

Multimorbidity and risk of falls, fractures, and joint replacements over two decades: Findings from the Hertfordshire Cohort Study.

To examine the relationship between level of morbidity burden and long-term risk of fractures, falls, and joint replacements in the community-dwelling participants of the Hertfordshire Cohort Study. Data were analyzed from 2997 individuals (age 59-73 at baseline). Outcomes (fractures, falls, and lower limb joint replacements) were identified using ICD-10 and OPCS-4 codes from Hospital Episode Statistics data, available from baseline (1998-2004) until December 2018. Number of systems medicated (marker of morbidity level) in relation to risk of outcomes was examined using sex-stratified Cox regression. Among both men and women, a greater number of systems medicated was related to increased risk of falls (P < 0.001) and lower limb joint replacements (P < 0.003). More systems medicated was only related to increased risk of fracture among women (P-values for trend of <0.001 among women and 0.186 among men). Higher morbidity was associated with increased risk of adverse health outcomes related to poor musculoskeletal health, but these relationships varied according to the musculoskeletal outcome studied. Intervention strategies to reduce multimorbidity among middle-aged and older people may hence reduce the burden of musculoskeletal aging. Geriatr Gerontol Int 2024; 24: 912-917.

The Use of Radiomics Data Obtained from ADC Map of Lumbar MRI and Machine Learning in Diagnosis of Osteoporosis

Background: Osteoporosis is a systemic skeletal disorder marked by reduced bone density and microarchitectural deterioration, leading to increased fracture risk. While the DEXA scan is the WHO-recommended diagnostic standard, its limitations necessitate alternative methods. Emerging magnetic resonance imaging (MRI) techniques, radiomics, and machine learning promise to enhance osteoporosis diagnosis through detailed analysis of lumbar MRI apparent diffusion coefficient (ADC) maps, potentially revolutionizing early detection and treatment strategies. Objectives: In this study, we are going to evaluate the performance of machine learning (ML) models using radiomics features of lumbar MRI ADC map for osteoporosis detection, and to identify significant features and their diagnostic thresholds. Specific performance metrics such as accuracy, sensitivity, specificity, and Area Under the receiver operating characteristic (ROC) Curve (AUC) were assessed. Patients and Methods: Patients and Methods: This retrospective study employed a cross-sectional design, with a total of 140 cases, including 21 with osteoporosis. The study's inclusion criteria consisted of concurrent lumbar MRI and DEXA within a year, while exclusion criteria included infectious or neoplastic lumbar lesions, fractures, instrumentation, significant osteodegenerative changes, cases where the first four lumbar vertebrae were not included in the imaging field, and absence of diffusion-weighted imaging. Manual segmentation of lumbar vertebrae from ADC maps was performed to create a comprehensive dataset, comprising 5,580 radiomics features per case. Subsequently, the top five features selected by fast correlation-based filter (FCBF) were used to test the performance of seven Machine Learning algorithms (k-Nearest neighbors, decision tree, random forest, logistic regression, support vector machine, naive bayes, and neural network). Statistical tests and ROC curve analysis were conducted to determine the significance and thresholds of these features. Results: The study included 140 cases, with 132 females (94.3%) and 8 males (5.7%), and a mean age of 65.32 ± 8.50 years. The mean BMI was 31.43 ± 5.53 kg/m² for females and 26 ± 3.59 kg/m² for males. In terms of demographic differences, no significant age difference was found between the osteoporotic and non-osteoporotic groups (P = 0.889). However, the osteoporotic group had significantly lower mean body weight (64.90 ± 10.13 kg vs. 74.68 ± 13.94 kg, P = 0.003) and BMI (27.40 ± 4.38 kg/m² vs. 31.77 ± 5.52 kg/m², P = 0.001) compared to the non-osteoporotic group. The median interval between DEXA and lumbar MRI was 1 month (range 0.1 - 11.87 months). The Neural Network model demonstrated the highest performance with an AUC of 0.616 and a classification accuracy of 0.764 using all features. The Naive Bayes model, using the top five features selected by FCBF, showed the highest performance with an AUC of 0.913, accuracy of 0.907, sensitivity of 0.667, and specificity of 0.95. All ML models’ performance were elevated by feature selection. Independent t-tests and Mann-Whitney U tests identified 521 and 670 significant features, respectively (P &lt; 0.05). ROC analysis revealed 58 features with AUC values above 0.70. Conclusion: This study's findings suggest that ML models, particularly the Naive Bayes algorithm, can effectively use lumbar ADC map radiomics to diagnose osteoporosis. These findings could enhance early detection and treatment strategies, potentially improving patient outcomes and reducing the burden of osteoporotic fractures. This study also established threshold values for significant features.

Current Status of Research on Anti-osteoporotic Drug Treatment and Compliance in Patients with Osteoporotic Fractures

Osteoporotic Fracture (OPF), also known as fragility fracture, is a low-energy, non-violent fracture that commonly occurs in the elderly. Such fractures mostly occur in the thoracolumbar vertebral body, hip, distal radius and other parts, and are the main factors that cause osteoporosis patients to be hospitalized for diagnosis and treatment. Secondary fractures are prone to occur after fractures, and anti-osteoporotic treatment can effectively prevent further fractures in patients with osteoporotic fractures. Due to factors such as patients and their families’ insufficient understanding of the necessity of anti-osteoporosis drug treatment after fragility fractures, insufficient awareness of the risk of re-fracture, lack of follow-up management of drug compliance after treatment, and untimely monitoring of anti-osteoporosis efficacy, etc. The treatment initiation rate and medication compliance of anti-osteoporosis drugs in patients with osteoporotic fractures are low. This article systematically reviews the incidence and disease burden of osteoporotic fractures, the understanding of diagnosis, treatment and management of osteoporotic fractures, the status of anti-osteoporotic drug treatment and compliance, and efficacy monitoring of patients after osteoporotic fractures. Provide a reference for establishing effective medication compliance management for OPF patients.

Relationship between Helicobacter pylori infection, osteoporosis, and fracture.

Osteoporotic fracture is a prevalent noncommunicable disease globally, causing significant mortality, morbidity, and disability. As the population ages, the healthcare and economic burden of osteoporotic fracture is expected to increase further. Due to its multifactorial features, the development of osteoporotic fracture involves a complex interplay of multiple risk factors, including genetic, environmental, and lifestyle factors. Helicobacter pylori, which infects approximately 43% of the world's population, has been associated with increased fracture risk due to hypochlorhydria from atrophic gastritis and systemic inflammation from elevated pro-inflammatory cytokines. However, the potential impact of H. pylori infection and eradication on fracture risk remains contentious among various studies due to the study design and inadequate adjustment of confounding factors including baseline gastritis phenotype. In this review, we provided a comprehensive evaluation of the current evidence focusing on the underlying mechanisms and clinical evidence of the association between H. pylori infection and osteoporotic fracture. We also discussed the potential benefits of H. pylori eradication on fracture risk.
