Prevalence Of Fractures Research Articles

Management of pediatric distal humerus metaphyseal-diaphyseal junction fracture: A systematic review and meta-analysis.

Fractures occurring at the metaphyseal-diaphyseal junction of the distal humerus in children are not commonly documented in the literature. Until this moment, there is no gold standard technique regarding its management and most surgeons treat it as a regular supracondylar humerus fracture by conventional pinning. This systematic review explores the relevant literature to assess the efficacy of different techniques. This review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Our literature search encompassed several online databases, including PUBMED/MEDLINE, Scopus, Web of Science Core Collection, and Google Scholar. Data from articles that met our general inclusion criteria were extracted and categorized into treatment method groupings. Functional and cosmetic outcomes, demographic characteristics, and complications were the main parameters used to analyze the data. Ten retrospective studies met our inclusion criteria with a total of 178 participants of unilateral pediatric distal humerus metaphyseal-diaphyseal junction fractures. Most literature chose closed reduction and percutaneous pinning in seven articles, followed by elastic stable intramedullary nail technique used in three articles, then conservative treatment was chosen in two articles, while only one article used lateral miniplate and assisted K-wire and another article used combined closed reduction and percutaneous pinning and intramedullary K-wire. As regards the operation time; elastic stable intramedullary nails had the shortest time with a mean of 39.7 min (range: 37.5-41.9 min), while closed reduction and percutaneous pinning had the longest time with a mean of 75.47 min (range: 55.9-92.1 min). The shortest healing time was observed in miniplate with a mean of 7.2 weeks, while the most prolonged was in conservative management with a mean of 12 weeks and closed reduction and percutaneous pinning was a mean of 10 weeks. Regarding Flynn's criteria, all participants received excellent and good except in closed reduction and percutaneous pinning; 13 cases were fair and 2 cases were poor. Regarding complications, the most commonly observed complication after metaphyseal-diaphyseal junction fracture was cubitus varus, the highest incidence was in conservative management (33% of cases), followed by closed reduction and percutaneous pinning (10.9% of cases), the least incidence was observed in elastic stable intramedullary nails (3.77% of cases), and none of the cases treated with mini plate developed this complication. Other complications were observed only with closed reduction and percutaneous pinning; 8.5% of cases developed fixation loss, 6.2% of cases had a significantly reduced range of motion, and one case refractured. Pediatric distal humerus metaphyseal-diaphyseal junction fractures should be distinguished from the more prevalent supracondylar humerus fractures, as conventional pinning techniques are associated with a higher incidence of complications and increased both operative and healing times.Level of evidence: III.

Quantitative CT lumbar spine BMD cutpoint value for classifying osteoporosis among older Chinese men can be the same as that of older Chinese women, both much lower than the value for Caucasians.

For older Caucasian women and men, the QCT (quantitative CT) lumbar spine (LS) bone mineral density (BMD) threshold for classifying osteoporosis is 80mg/ml. It was recently proposed that, for older East Asian women, the QCT LS BMD value equivalent to the Caucasian women's threshold of 80mg/mL is about 45∼50mg/ml. For a data of 328 cases of Chinese men (age: 73.6 ± 4.4years) who had QCT LS BMD and DXA LS BMD at the same time and with the DXA BMD value of ≤ 0.613g/cm2 to classify osteoporosis, the corresponding QCT LS BMD threshold is 53mg/ml. Osteoporotic-like vertebral fracture sum score (OLVFss) ≤ -2.5 has been proposed to diagnose osteoporosis. For 316 cases of Chinese men(age:73.7±4.5 years), OLVFss ≤ -2.5 defines an osteoporosis prevalence of 4.4%; to achieve this osteoporosis prevalence, the corresponding QCT LS BMD value is < 47.5mg/ml. In the China Action on Spine and Hip Status study, a Genant grades 2/3 radiographic 'osteoporotic vertebral fracture' prevalence was 2.84% for Chinese men (total n = 1267, age: 62.77 ± 9.20years); to achieve this osteoporosis prevalence, the corresponding BMD value was < 42.5mg/ml. In a study of 357 Beijing older men, according to the clinical fragility fracture prevalence and femoral neck DXA T-score, the QCT LS BMD value to classify osteoporosis was between 39.45mg/ml and 51.38mg/ml. For older Chinese men (≥ 50years), we recommend the cutpoint for the QCT LS BMD definition of osteoporosis to be 45∼50mg/ml which is the same as the value for Chinese women.

Undiagnosed vertebral fragility fractures in patients with distal radius fragility fractures: an opportunity for prevention of morbimortality in osteoporotic patients in developing countries.

This study's main goal was to look into the frequency, location, kind, and severity of asymptomatic vertebral fragility fractures (VFF) in people who had fractures of the fragility of the distal radius. Although VFF is frequently misdiagnosed, it is linked to higher mortality, morbidity, and hip fracture risk. The study also attempted to investigate the relationship between VFF and certain demographic and lifestyle factors, as well as FRAX data, in this patient population. Between January, 2021, and January, 2022, individuals with low-energy distal radial fractures who presented to the emergency room of tertiary care hospital of Karachi, Pakistan, were the subject of a cross-sectional study and were 45years of age or older except those who fitted the exclusion criteria (n = 208). The thoracic and/or lumbar spine was imaged using radiology, and information on demographics, way of life, and FRAX (Fracture Risk Assessment Tool) was gathered. Using the Genant semiquantitative approach, an impartial and blinded orthopaedist identified VF in the images and determined their severity. SPSS version 20 was used to analyse the data. Two hundred eleven (41.21%) of them were found to have radiographic VFF and only 12 (2.34%) of the 512 patients who were tested were getting osteoporotic therapy. The thoracic spine (32.7%), followed by the lumbar spine (43.12%), was the area most frequently afflicted. In 24.17% of the patients, multiple fractures of the thoracolumbar spine were found. The wedge form (54.5%), followed by biconcave (30.81%) and crush (14.7%), was the most prevalent VFF type. The majority of detected VFF were rated as having a 25-40% height loss (64.9%) then severe (> 40%) fractures (35.1%), according to the Genant grading method. Notably, there were no variations in smoking, drinking, BMI, or FRAX score between patients with and without VFF that were statistically significant. Based on our study's findings, it is clear that osteoporotic vertebral fragility fractures occur in almost half of individuals with distal radius fractures. The lumbar spine is notably the most affected region, predominantly with wedge fractures. Given the high prevalence of asymptomatic vertebral fragility fractures (VFF), proactive measures are necessary to mitigate associated risks. Prioritising comprehensive fall risk assessments for these patients and interventions to enhance bone mineral density and strength are crucial. Early identification of asymptomatic VFF enables timely intervention, optimising patient care and minimising the risk of complications in this vulnerable population.

High and very high risk of osteoporotic fracture in Colombia, 2003-2022: identifying diagnostic and treatment gaps.

This study aimed to assess the clinical features and refracture rates among patients with high- and very-high-risk osteoporosis in Colombia, highlighting diagnostic and treatment gaps. A retrospective observational study was conducted using the medical records of patients aged ≥ 50years who experienced fragility fractures between 2003 and 2022. Clinical and demographic characteristics at the time of the initial fracture were analyzed, as well as the subsequent imminent risk (refracture rate) and the diagnosis and treatment gap. 303.982 fragility fractures occurred, and only 5.3% of patients were diagnosed with osteoporosis upon discharge. The most prevalent index fractures were forearm, vertebral, rib, and hip. Only 17.8% of the cohort had a matched osteoporosis diagnosis, indicating a low healthcare capture. Among the diagnosed patients, 10.08% were classified as high- and very high-risk of fracture, predominantly women with a mean age of 73years. Comorbidities included diabetes, Sjögren's syndrome, and heart failure. The prevalence of osteoporosis has increased significantly from 2004 to 2022, possibly due to improved detection methods, an aging population, or a combination of both. Despite this increase, treatment delay was evident. Refractures affected 70.5% of the patients, with forearm, hip, humerus, and vertebral fractures being the most common, with a mean time of refracture of 7months. Significant delays were observed in the diagnosis and treatment of fragility fractures. Colombia's government and health system must address osteoporosis by implementing national policies that prioritize osteoporosis and fragility fracture prevention and reduce delays in diagnosis and treatment.

The association between computed tomography-based osteosarcopenia and osteoporotic vertebral fractures: a longitudinal study.

Osteoporosis and sarcopenia usually coexist in older population. The concept of osteosarcopenia has been proposed in recent years. However, studies on the relationship between osteosarcopenia and the risk of fracture are rare, and the association is unclear at present. This study aimed to investigate the association between osteosarcopenia evaluated based on chest computed tomography (CT) and osteoporotic vertebral fracture (OVF). This study recruited 7906 individuals aged 50 years and older who did not have OVFs and underwent chest CT for physical examination between July 2016 and September 2019. Subjects were followed up annually until June 2023. Osteosarcopenia was defined by a low muscle area of the erector spinae (< 25.4 cm2) and the bone attenuation (Hounsfield unit, HU < 135). Genant's grades were used to define OVFs. Control subjects were selected by Propensity Score Matching at a ratio 20:1. Cox proportional hazards models were used to assess the associations between osteosarcopenia and OVFs. Of the 7906 participants included, 95 had a new OVF within a median follow-up of 3 years. A total of 1900 control subjects were matched. Individuals in the osteosarcopenia group had a higher prevalence of spinal fractures than those in normal group (16.4% vs. 0.4%, P < 0.001). Osteosarcopenia was independently associated with OVF (adjusted hazard ratio (aHR): 12.67, 95% confidence interval (CI) 3.79-42.40) and severe OVF (aHR = 14.07, 95% CI 1.84-107.66). Similar trends were observed in males, females and those subjects aged older than 60 years. Osteosarcopenia had good predictive efficacy for OVF (area under the curve = 0.836). A nomogram was also developed for clinical application. Osteosarcopenia assessed based on chest CT was associated with OVF, and osteosarcopenia has good performance for vertebral fracture prediction.

Associations of different dietary patterns, bone mineral density, and fracture risk among elderly women: the China Osteoporosis Prevalence Study.

Despite the fact that China amounts to one-fifth of the world's population, has a higher proportion of the elderly, and has a higher prevalence of osteoporosis and fracture, limited studies have investigated the association between dietary patterns and bone mineral density (BMD) as well as fracture risk among the elderly Chinese population. We aimed to investigate the association between different dietary patterns and BMD as well as the risk of fractures, and this association may vary between elderly women and men. Building upon the China Osteoporosis Prevalence Study, we included 17,489 subjects aged ≥40 years old randomly sampled across 44 counties/districts of 11 provinces or municipalities in China who completed a food frequency questionnaire. BMD was measured by dual x-ray absorptiometry. Vertebral fracture was defined based on lateral spine radiographs using the semi-quantitative technique of Genant. A diet rich in "carnivorous", "vegetarian", "dairy, fruit, and egg" was significantly associated with higher BMD at total hip (TH), femoral neck (FN), and lumbar spine 1-4 (L1-4). Yet, a diet rich in "beverage and fried food" was associated with a lower BMD at the FN and L1-4. High quartiles of the carnivorous diet were associated with 34%-39% reduced risk of clinical fracture in the past 5 years and vertebral fracture. Stronger associations were observed among women. Sensitivity analysis among postmenopausal women presented even stronger positive associations between carnivorous and vegetarian diets and high BMD, as well as between carnivorous diet and reduced risk of fractures. Our study suggested that a diet rich in meat, vegetables, and dairy, fruit, and eggs might be associated with greater BMD and a lower fracture risk, while beverage and fried foods may be associated with a lower BMD at L1-4, especially among elderly women. These findings are relevant to provide recommendations on dietary nutrition regarding the elderly population at high risk of osteoporosis and fractures, especially postmenopausal women.

Pediatric skeletal injuries in emergency department; an alarm of child maltreatment in Egypt: A cross-sectional study

BackgroundChild physical abuse, a type of child maltreatment (CM), poses a significant global public health concern. Nonaccidental fractures and soft tissue injuries, which encompass any action that directly or indirectly harms a child, are the primary indicators of physical abuse in children. ObjectiveThis study aimed to investigate the prevalence, risk factors, and outcomes of accidental and nonaccidental skeletal fractures in a sample of Egyptian children. MethodsA cross-sectional analytical study was conducted between March 2022 and August 2022. A total of 156 children who presented with skeletal injuries and attended Mobarak Central Hospital were enrolled. Patients were subjected to full history taking, complete examination, and investigations. A structured questionnaire was administered to all the legal guardians. ResultsPhysical abuse was reported in 22.4 % of cases, while medical neglect was reported in 19.9 % of cases. The incidence of physical abuse was notably higher among children whose fathers were smokers and/or drug addicts (p ≤ 0.05). The most common form of physical abuse was hitting (94.3 %). Among skeletal injuries, fractures were predominant (94.3 %), primarily closed fractures associated with contusions. Fractures of the upper limb accounted for the highest incidence (94.3 %) of skeletal injuries, and 60 % of physically abused children experienced moderate-severity injuries. ConclusionThe most common fracture observed in abused children is the upper limb fracture, typically involving a single bone. Clinicians should be more vigilant in suspecting abuse, even in cases where there is an isolated fracture, and advocate for the development of parental training programs.

Prevalence and risk factors for atypical femoral fracture among Lebanese patients with hip and shaft fractures.

This retrospective study investigates the prevalence of atypical femoral fractures (AFFs) among patients admitted with hip and shaft fractures at a tertiary referral center in Beirut, Lebanon. We analyzed electronic medical records and radiology studies of patients aged above 40 admitted with hip and shaft fractures between January 2006 and December 2019. Fractures were confirmed by ICD9 or ICD10 codes. All cases were reviewed by radiologists, and AFFs were identified according to the 2013 revised ASBMR criteria. We identified 1366 hip and shaft fracture patients, of which 14 female patients had 19 AFFs. This represents a prevalence of 1.0% among all hip and shaft fractures patients and 1.7% among all female hip and shaft fracture patients. Bilateral AFFs were found in 5 of the 14 patients. Patients with AFF tended to be younger, with a mean age of 74.3 (±8.6) yr compared to 78.0 (±10.6) for patients with non-AFF fractures. A total of 36% of AFF patients had a prior history of non-traumatic fracture at first admission. A high percentage of patients with AFFs reported intake of proton pump inhibitors (42.9%) and glucocorticoids (21.4%). Bisphosphonate exposure was noted in 64.3% of AFF patients. None of the AFF patients were active smokers or consumed alcohol regularly. BMD assessments were available for 7 AFF patients, indicating osteoporosis in 4 and osteopenia in 3 cases. Hip axis length measurements showed no significant difference between AFF patients (N = 7) and sex and age-matched controls (N = 21). The study underlines the prevalence and characteristics of AFFs in Lebanon, which is consistent with the numbers reported in the literature (0.32%-5%). A larger prospective study that includes hospitals across the nation is needed to gain a more comprehensive view of the prevalence of AFFs in the Lebanese population.

Discrepancies in the prevalence, risk factors, diagnosis, and treatment of stress fractures between long-distance runners and sprinters: A qualitative review of systematic reviews

This qualitative review of systematic reviews consolidates current knowledge on stress fractures among endurance athletes and sprinters, including epidemiology, risk factors, diagnosis, and treatment strategies. A search across PubMed, Web of Science, SCOPUS, Science Direct, and Google Scholar, limiting results to articles published within the last year, yielded 90 relevant articles. Initial search results were narrowed down to 56 articles following abstract screening, with an additional article obtained through direct author correspondence. Stress fractures, a subset of bone stress injuries, result from persistent mechanical pressure surpassing bone regeneration capacity. They predominantly affect lower extremities, notably the tibia and metatarsals in endurance runners, and the toe phalanx in sprinters. Various risk factors contribute to stress fracture susceptibility, including gender, nutritional deficiencies, biomechanical factors, and psychological aspects like perfectionism and fear of failure. Diagnosis involves detailed patient history, clinical examination, and imaging modalities such as MRI, which remains the gold standard. Treatment emphasizes rest, gradual return to activity, and addressing underlying risk factors. Surgical intervention is reserved for high-risk fractures or cases of non-union. Preventive measures encompass nutritional optimization, biomechanical assessment, appropriate footwear, and psychological support. Notably, strategies targeting the Female Athlete Triad and ensuring adequate energy availability are crucial in both endurance and sprinting athletes. While more research directly comparing distance runners to sprinters is warranted, along with more sprinting-related research in general, this review provides a comprehensive understanding of stress fractures in endurance athletes and sprinters, aiding clinicians in diagnosis, management, and prevention strategies to optimize athlete health and performance.

Implant-Positioning and Patient Factors Associated with Acromial and Scapular Spine Fractures After Reverse Shoulder Arthroplasty

Background: This study aimed to identify implant positioning parameters and patient factors contributing to acromial stress fractures (ASFs) and scapular spine stress fractures (SSFs) following reverse shoulder arthroplasty (RSA). Methods: In a multicenter retrospective study, the cases of patients who underwent RSA from June 2013 to May 2019 and had a minimum 3-month follow-up were reviewed. The study involved 24 surgeons, from 15 U.S. institutions, who were members of the American Shoulder and Elbow Surgeons (ASES). Study parameters were defined through the Delphi method, requiring 75% agreement among surgeons for consensus. Multivariable logistic regression identified factors linked to ASFs and SSFs. Radiographic data, including the lateralization shoulder angle (LSA), distalization shoulder angle (DSA), and lateral humeral offset (LHO), were collected in a 2:1 control-to-fracture ratio and analyzed to evaluate their association with ASFs/SSFs. Results: Among 6,320 patients, the overall stress fracture rate was 3.8% (180 ASFs [2.8%] and 59 SSFs [0.9%]). ASF risk factors included inflammatory arthritis (odds ratio [OR] = 2.29, p &lt; 0.001), a massive rotator cuff tear (OR = 2.05, p = 0.010), osteoporosis (OR = 2.00, p &lt; 0.001), prior shoulder surgery (OR = 1.82, p &lt; 0.001), cuff tear arthropathy (OR = 1.76, p = 0.002), female sex (OR = 1.74, p = 0.003), older age (OR = 1.02, p = 0.018), and greater total glenoid lateral offset (OR = 1.06, p = 0.025). Revision surgery (versus primary surgery) was associated with a reduced ASF risk (OR = 0.38, p = 0.019). SSF risk factors included female sex (OR = 2.45, p = 0.009), rotator cuff disease (OR = 2.36, p = 0.003), osteoporosis (OR = 2.18, p = 0.009), and inflammatory arthritis (OR = 2.04, p = 0.024). Radiographic analysis of propensity score-matched patients showed that a greater increase in the LSA (ΔLSA) from preoperatively to postoperatively (OR = 1.42, p = 0.005) and a greater postoperative LSA (OR = 1.76, p = 0.009) increased stress fracture risk, while increased LHO (OR = 0.74, p = 0.031) reduced it. Distalization (ΔDSA and postoperative DSA) showed no significant association with stress fracture prevalence. Conclusions: Patient factors associated with poor bone density and rotator cuff deficiency appear to be the strongest predictors of ASFs and SSFs after RSA. Final implant positioning, to a lesser degree, may also affect ASF and SSF prevalence in at-risk patients, as increased humeral lateralization was found to be associated with lower fracture rates whereas excessive glenoid-sided and global lateralization were associated with higher fracture rates. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Incidence, patterns, and management of frontal sinus fractures: A 10-year retrospective study at a tertiary medical center, Saudi Arabia.

To assess the prevalence of various frontal sinus fractures (FSF) and examine the relationships between these fractures, types of treatments, and potential complications. A retrospective study was carried out in King Saud Medical City, Riyadh, Saudi Arabia. The study analyzed the records of patients who were diagnosed and treated with FSF from 2011-2021. Files with missing documents or incomplete treatment were excluded. The retrieved data includes: patients age, gender, types, locations, treatment, and complications of FSF. Data was analyzed by the statistical Package for the Social Sciences Statistics, version 23.0 using descriptive statistics and Chi-square test. A total of 72 cases were included, 94.4% males and 5.6% females. Road traffic accidents were the common cause of trauma (91%). Frontal sinus fractures were unilateral in 59.7% and associated other injuries in 80.6% of cases. Anterior table fractures were the largest proportion (58.3%), followed by anterior and posterior table (37.5%). The carried out surgical procedures were obliteration (23.9%), cranialization and obliteration (23.9%), and fixation only (52.2%). The post-operative complications were categorized into; neurological (22.2%), ophthalmic (15.3%), infection (2.8%), and deformity (16.7%). Anterior and posterior table had the highest percentage among these categories. Frontal sinus fractures were mostly required surgical treatment (63.9%) and post-operative complications occurred especially the neurological and ophthalmic. We recommend studies on the association of complications and different types of obliteration materials.

Pickleball-Related Fractures in the United States From 2002 to 2022: An Analysis Using the NEISS Database.

Pickleball is one of the fastest-growing sports in the United States, with more than an 11-fold increase in injuries from 2010 to 2019. To (1) determine the prevalence and demographic variables associated with pickleball-related fractures among patients evaluated at emergency departments in the United States between 2002 and 2022 and (2) identify variables influencing patient disposition status. Descriptive epidemiology study. The US Consumer Product Safety and Commission's publicly available database, the National Electronic Injury Surveillance System (NEISS), was used in this study. Analyses consisted of descriptive statistics for fracture prevalence and demographic variables as well as univariate analysis for disposition status (discharged home vs hospital admission). A total of 397 pickleball-related fractures were recorded between 2002 and 2022, which indicated a 90-fold increase in our study period. Based on weighted national average of NEISS sampling, this equated to approximately 5400 fractures annually. Players who sustained pickleball fractures were primarily aged >60 years (n = 344 [87%]; P < .001) and female (n = 273 [69%]; P < .001). Most fractures involved the upper extremity (n = 262 [66%]; P < .001), with the most common ones involving the radius (n = 79 [30%]), humerus (n = 22 [8%]), and ulna (n = 8 [3%]). Fractures were due most commonly to falls (n = 365 [92%]; P < .001) and occurred in the winter months (n = 142 [36%]; P < .001). There was a significant difference in disposition status, with most patients discharged (n = 320 [81%] vs n = 77 [19%] for hospital admission; P < .001). Univariate analysis revealed that age >60 years, male sex, and fractures to the trunk and lower extremity all led to significantly increased odds of being admitted (odds ratios: 2.27, 2.31, 2.89, and 13.8, respectively). Between 2002 and 2022, there was a 90-fold increase in pickleball-related fractures. Most fractures were of the upper extremity after a fall in women aged >60 years. Despite female fracture predominance, men were 2.3 times more likely to be admitted after sustaining a fracture.

Smoking habits and osteoporosis in community-dwelling men subjected to dual-X-ray absorptiometry: a cross-sectional study.

Active and Environmental Tobacco Smoke (ETS) are a global cause of death. Osteoporosis (Op) is the most common metabolic bone disorder worldwide, impacting on mortality and disability, with high health and welfare costs. Active smoking is a known risk factor for Op, but there is few information regarding Op and ETS in men. The study aim is to evaluate the association between smoking habits and Op in community-dwelling men that have been subjected to Dual-X-ray Absorptiometry and completed a questionnaire about their own and cohabiter's smoking habits. We performed a cross-sectional study based on administrative data. This study is part of the SIMON protocol. The binary logistic regression analysis was used to estimate the role of ETS on the risk of Op, adjusting for age, body mass index (BMI), type 2 diabetes mellitus (T2DM) and eGFR. Four hundred sixteen men were selected and, based on questionnaire replies, 167 were classified as current smokers (CS), 93 as passive smokers (PS) and 156 as never smokers (NS). NS showed a lower prevalence of past fragility fracture, radiological features of osteoporosis and hypovitaminosis D compared to PS and CS (p < 0.05). NS showed a lower prevalence of Op compared to PS and CS, also after correction for age, BMI, T2DM and eGFR (p < 0.05). The study results demonstrate that PS and CS have a higher risk of Op, fragility fractures and vitamin D deficiency compared to NS.

High prevalence of morphometric vertebral fractures opportunistically detected on thoracic radiograms in patients with non-functioning pituitary adenoma.

Vertebral fractures (VFs), the hallmark of skeletal fragility, have been reported as an emerging complication in patients with pituitary diseases associated with hormonal excess and/or deficiency, independently from bone mineral density. Non-functioning pituitary adenoma (NFPA) is amongst the most frequent pituitary adenomas; however, skeletal health in this context has never been investigated. We aimed at assessing the prevalence and the determinants of morphometric VFs in patients with NFPA. We enrolled 156 patients (79M/77F, mean age 55.75 ± 12.94years) at admission in Neurosurgery Unit before trans-sphenoidal surgery and compared them with an age and sex-matched control group of subjects with neither history/risk factors for secondary osteoporosis nor pituitary disorders. We performed a vertebral morphometric evaluation of the thoracic spine on pre-operative X-ray images (MTRx) and collected biochemical, demographic, and clinical data from the entire cohort. The prevalence of thoracic VFs in patients with NFPA was significantly higher than the control group (26.3% vs. 10.3%; p < 0.001). In the NFPA group, 20 patients (48.8% of the fractured patients) showed multiple VFs, 14 (34.1% of them) showed moderate/severe VFs. Patients with VFs were significantly older and had lower serum free triiodothyronine (fT3) levels than non-fractured ones (p = 0.002 and p = 0.004; respectively). The prevalence of secondary male hypogonadism was higher among men with VFs as compared to those with no VFs (72% vs. 48.1%; p = 0.047). Consistently, total testosterone levels in males were significantly lower in fractured patients than in non-fractured ones (p = 0.02). The prevalence of gonadotroph adenomas was significantly higher among patients with VFs (p = 0.02). In multiple logistic regression analysis, older age and lower serum fT3 levels were independent factors predicting the risk for VFs. For the first time, we reported a high prevalence of thoracic radiological VFs in patients with NFPAs. Our data should prompt clinicians to proceed with a clinical bone fragility evaluation already during the diagnostic work-up, particularly in those with concomitant hypogonadism, or in those with older age and/or with lower fT3.

Mild Autonomous Cortisol Secretion (MACS) - Related Osteoporosis.

Mild autonomous cortisol secretion (MACS) has thus far been associated with several comorbidities, among which osteoporosis and fractures appear to be highly prevalent. Recent guidelines for adrenal incidentalomas have updated the definition of MACS, currently formulated on serum cortisol after a 1-mg dexamethasone test above 1.8 µg/dL or 50 nmol/L. Previous studies on bone health in adrenal incidentalomas had adopted different definitions of MACS, which produced heterogenous results in terms of fracture prevalence. This review aims to summarize the clinical impact of MACS in relation to fractures, bone quantity and quality, by providing a thorough update on MACS-related osteoporosis (MACS-ROP). Room for research in this area is large, and management of this comorbidity still needs to be elucidated.

A multicenter and epidemiological study of patterns and treatment strategies for mandibular condyle fractures

To evaluate retrospectively the epidemiological characteristics of the prevalence, type and treatment modalities of the condylar mandibular fractures. Data of all patients who underwent surgical or nonsurgical management for condyle mandibular fracture were collected. The study was conducted to assess the trauma etiology, age group, gender, treatment method, anatomic distribution of injury and complications by reviewing patients’ records. There were 139 patients with 171 mandibular condylar fractures. Among these patients, 85% were men, with an overall male-to-female ratio of 5.6:1. The highest occurrence of trauma was in the 21-30 years age group. The most frequently observed etiology was motorcycle traffic accidents and the subcondylar region was the most common location with 109 fractures. There was statistically significant difference between treatments (p &lt; 0,001). In the nonsurgical treatment group, the prevalence of complications was observed compared to the surgical group (p &lt; 0.001). The predominant complications were: mouth opening limitation, mandibular deviation, malocclusion, temporomandibular disorder, paresthesia and facial paralysis. Considering the limitations of this study, subcondylar fractures were the most frequent, especially in men aged 21-30 years, and the surgical treatment showed the fewest complications.

Quantitative characterization and fracture morphology in reservoirs with various lithologies: An experimental investigation

Accurately quantifying the development of hydraulic fractures is pivotal for further elucidating the relationship between reservoir physical properties and hydraulic fracture propagation. In this research, we centered on reservoirs featuring diverse lithologies, procured downhole full-diameter cores, conducted triaxial hydraulic fracturing experiments, and employed CT scanning and electron microscopy to characterize fracture morphology. The primary findings are summarized as follows: sandstones specimens typically exhibit bi-wing fractures inclined at a certain angle to σH, with internal microfractures predominantly comprised of corrugated shear fractures traversing mineral grains. Conversely, conglomerate specimens display a higher prevalence of branching fractures, with fracture zones forming in areas of gravel densities and weak heterogeneous matrices, along with the development of multiple microfractures. Volcanic rock specimens fractures primarily propagate via deflection following NF activation, showcasing two modes of microfracture propagation: through and alongside the NF. Quantitative parameters of fracture morphology indicate that the fractal dimension ranges from 2.02 to 2.08 for sandstone fractures, 2.19 to 2.22 for conglomerate fractures, and 2.11 to 2.13 for volcanic rock fractures. Notably, the NF filler in volcanic rock undergoes erosion by fracturing fluid, accumulating non-uniformly on the surface of rock crystals, thereby augmenting fracture tortuosity. Additionally, the fracture surface area of conglomerates surpasses that of sandstones and volcanic rocks by 1.3 times, with the stripping rate of conglomerate fracture surfaces exceeding 10%. Furthermore, the average normal width of conglomerate fractures surpasses 2 mm, whereas volcanic rock and sandstone measure 1.6 mm and 1.1 mm, respectively. Notably, sandstone fractures exhibit uniform normal width distribution, while conglomerate fractures, especially those around gravels and eroded by fracturing fluid, manifest larger widths. Moreover, NF influenced volcanic rock fractures also exhibit wider widths. Elucidating the quantitative attributes of fracture morphology in lithologically diverse reservoirs holds significant implications for formulating hydraulic fracturing and targeted optimization strategies aimed at enhancing fracturing efficacy.
