[Expert consensus on integrated traditional Chinese and western medicine diagnosis and treatment for osteoporotic fractures].

Osteoporotic fractures represent the most severe complications of osteoporosis,characterized by insidious onset,high mortality and disability rates,and a steadily increasing incidence,imposing a significant socioeconomic burden. Western medicine has advantages in diagnosis and surgical interventions,while traditional Chinese medicine excels in holistic management and the restoration of bodily equilibrium. The integration of both traditional Chinese medicine (TCM) and western medicine emerges as an effective therapeutic strategy for osteoporotic fractures. In order to propagate the concept of integrated diagnosis and treatment,foster the advancement of integrated medical techniques for osteoporotic fractures,and establish standardized and normative protocols for disease prevention,diagnosis,and treatment,a consensus expert group,led by Geriatric Branch of Chinese Geriatrics Society,the Young Osteoporosis Group of Orthopedics Branch of Chinese Medical Association,Osteoporosis Group of Orthopedics Branch of Chinese Physician Association,and Osteoporosis Professional Committee of the Shanghai Society of Integrated Traditional Chinese and Western Medicine,was established. This group engaged in deliberations and formulated the "Expert Consensus on Integrated Traditional Chinese and Western Medicine Diagnosis and Treatment of Osteoporotic Fractures" elucidating the concept of integrated medicine and offering recommendations in the domains of prevention,diagnosis,and treatment,with the aspiration of ameliorating the prognosis of osteoporotic fractures and enhancing the quality of life for these patients.

Comparative analysis of anti-osteoporosis medications in preventing vertebral body fractures after balloon kyphoplasty.

This retrospective study compared the efficacy of anabolic agents (romosozumab and teriparatide) with that of alendronate in preventing subsequent vertebral body fractures (SVBFs) after balloon kyphoplasty (BKP). All anabolic agents significantly reduced SVBFs. Romosozumab was most effective in increasing bone mineral density (BMD) and completely suppressed distant vertebral body fractures. INTRODUCTION: To determine optimal anti-osteoporosis medications, we compared romosozumab and teriparatide to alendronate as a control from perioperative BKP to the 1st postoperative year for treatment and secondary fracture prevention in osteoporosis. METHODS: A total of 603 patients who underwent initial BKP for osteoporotic vertebral fractures were evaluated and categorized into five groups based on drug administration: romosozumab (group R, 155 patients), twice-weekly teriparatide (group TW, 48), weekly teriparatide (group W, 151), daily teriparatide (group D, 138), and alendronate (control) (group C, 111). The 1-year incidence of SVBFs, BMD change rate, and probability of requiring BKP were compared among the groups. RESULTS: SVBF incidence was 3.9%, 6.5%, 8.3%, 6.0%, and 14.4% in groups R, D, TW, W, and C, respectively, with all other groups exhibiting significantly lower rates than group C. The groups that administered the anabolic agents had a notably lower incidence of distant fractures than group C. Compared with group C, group R showed significantly higher BMD change rates in lumbar vertebral bodies at 4, 8, and 12 months and group D at 12 months. Anabolic agent groups exhibited significantly higher improvement rates than group C after conservative treatment alone. CONCLUSION: The anabolic agents were found to be more effective at reducing the incidence of SVBF (especially distant vertebral fractures) than alendronate. These agents decreased the rate of repeat BKP even after the occurrence of a fracture. Overall, the use of an anabolic agent for the treatment of osteoporosis after BKP is better than the use of alendronate, even when treatment is initiated in the perioperative stage.

Improving patients' experiences of diagnosis and treatment of vertebral fracture: co-production of knowledge sharing resources.

BACKGROUND: Osteoporosis involves changes to bones that makes them prone to fracture. The most common osteoporotic fracture is vertebral, in which one or more spinal vertebrae collapse. People with vertebral fracture are at high risk of further fractures, however around two-thirds remain undiagnosed. The National Institute for Health and Care Excellence (NICE) recommends bone protection therapies to reduce this risk. This study aimed to co-produce a range of knowledge sharing resources, for healthcare professionals in primary care and patients, to improve access to timely diagnosis and treatment. METHODS: This study comprised three stages: 1. In-depth interviews with primary care healthcare professionals (n = 21) and patients with vertebral fractures (n = 24) to identify barriers and facilitators to diagnosis and treatment. 2. A taxonomy of barriers and facilitators to diagnosis were presented to three stakeholder groups (n = 18), who suggested ways of identifying, diagnosing and treating vertebral fractures. Fourteen recommendations were identified using the nominal group technique. 3. Two workshops were held with stakeholders to co-produce and refine the prototype knowledge sharing resources (n = 12). RESULTS: Stage 1: Factors included lack of patient information about symptoms and risk factors, prioritisation of other conditions and use of self-management. Healthcare professionals felt vertebral fractures were harder to identify in lower risk groups and mistook them for other conditions. Difficulties in communication between primary and secondary care meant that patients were not always informed of their diagnosis, or did not start treatment promptly. Stage 2: 14 recommendations to improve management of vertebral fractures were identified, including for primary care healthcare professionals (n = 9) and patients (n = 5). Stage 3: The need for allied health professionals in primary care to be informed about vertebral fractures was highlighted, along with ensuring that resources appealed to under-represented groups. Prototype resources were developed. Changes included help-seeking guidance and clear explanations of medical language. CONCLUSIONS: The study used robust qualitative methods to co-produce knowledge sharing resources to improve diagnosis. A co-production approach enabled a focus on areas stakeholders thought to be beneficial to timely and accurate diagnosis and treatment. Dissemination of these resources to a range of stakeholders provides potential for substantial reach and spread.

Understanding the long-term impact of incident osteoporotic fractures on healthcare utilization and costs in Korean postmenopausal women.

This study provides long-term evidence that healthcare resource utilization and costs of care in women who experienced incident osteoporotic fractures remained higher than those in women without fractures over a span of 5 years. These findings emphasize the importance of early diagnostics and treatment for osteoporosis. PURPOSE: To evaluate healthcare resource utilization (HCRU) and costs of care over 5 years after the incident osteoporotic fractures (OF) in postmenopausal women. METHODS: We used data from the National Health Insurance Service databases 2011-2018. Women aged ≥ 50 years with incident OF (OF group) were matched to women without OF (non-OF group). HCRU (inpatient, outpatient, and emergency room [ER] visits) and costs of care (inpatient, outpatient, and ER visits) during the 5-year follow-up period were derived after propensity score matching (PSM). Additionally, we identified women with subsequent fractures within the first 2 years after the incident OF. RESULTS: After PSM, 47,238 OF and 134,813 non-OF women were identified. HCRU rates and costs of care were highest in the first year after OF and decreased substantially, but remained higher in the OF group during the entire follow-up period. The increase in cumulative HCRU rates over 5 years was highest in inpatient admissions with ER visits (138% higher in OF vs non-OF). The cumulative total costs over 5 years were 73% higher in the OF group than in the non-OF group, which was mostly driven by inpatient costs. Trends were similar for women with subsequent fractures, but they generally showed higher HCRU and costs than those in the total OF group. CONCLUSION: OF imposes a substantial and sustained economic burden on women, resulting in an approximately twofold increase in the cumulative cost over 5 years compared to women without fracture, which highlights the need for early diagnostics and treatment of osteoporosis.

Evaluating Male Patients' Understanding of Osteoporosis Evaluation and Treatment Following a Distal Radius Fracture.

PURPOSE: Current estimates suggest that 1-2 million men in the United States have osteoporosis, yet the majority of osteoporosis literature focuses on postmenopausal women. Our aim was to understand men's awareness and knowledge of osteoporosis and its treatment. METHODS: Semistructured interviews were conducted with 20 male patients >50 years old who sustained a low-energy distal radius fracture. The goal was to ascertain patients' knowledge of osteoporosis, its management, and experience discussing osteoporosis with their primary care physicians (PCP). RESULTS: Participants had little knowledge of osteoporosis or its treatment. Many participants regarded osteoporosis as a women's disease. Most participants expressed concern regarding receiving a diagnosis of osteoporosis. Several patients stated that they believe osteoporosis may have contributed to their fracture. Families, friends, or mass media served as the primary information source for participants, but few had good self-reported understanding of the disease itself. The majority of participants reported never having discussed osteoporosis with their PCPs although almost half had received a dual x-ray absorptiometry scan. Participants expressed general interest in being tested/screened and generally were willing to undergo treatment despite the perception that medication has serious side effects. One patient expressed concern that treatment side effects could be worse than having osteoporosis. CONCLUSION: Critical knowledge gaps exist regarding osteoporosis diagnosis and treatment in at-risk male patients. Specifically, most patients were unaware they could be osteoporotic because of the perception of osteoporosis as a women's disease. Most patients had never discussed osteoporosis with their PCP. CLINICAL RELEVANCE: Male patients remain relatively unaware of osteoporosis as a disease entity. Opportunity exists for prevention of future fragility fractures by improving communication between patients and physicians regarding osteoporosis screening in men following low-energy distal radius fractures.

Progression toward Vertebral Collapse of Vertebral Metastases Treated with Percutaneous Vertebroplasty: Rate and Risk Factors.

PURPOSE: To evaluate of the rate of and risks for progression toward collapse in vertebral metastases (VMs) treated with percutaneous vertebroplasty (PV). MATERIALS AND METHODS: A total of 151 PVs were performed in 81 patients with vertebral metastases and were retrospectively analyzed. Follow-up imaging was performed at 12 months to measure vertebral body height and to report vertebral collapse at the level of the treated vertebrae. Vertebral characteristics (spine instability neoplastic score [SINS], number of lysed cortices, and prior radiotherapy) and procedural parameters (Saliou score, cortical contact with cement, and intradiscal cement leakage) were compared between the group of patients with and without collapse of the treated vertebrae. RESULTS: Of the vertebrae treated with PV, 41 of 151 (27%) progressed toward collapse. Vertebral collapse was influenced by a high SINS (odds ratio [OR] = 1.27, P = .004), SINS value > 9 (OR = 2.96, P = .004), intradiscal cement leakage (OR = 2.18, P = .048), pre-existing spinal deformity (OR = 2.65, P = .020), and pre-existing vertebral fracture (OR = 3.93, P = .045). A high Saliou score (OR = 0.82, P = .011), more than 3 cortices in contact with the cement (OR = 0.38, P = .014), and preserved spinal alignment (OR = 0.38, P = .020) were associated with a lower incidence of collapse. CONCLUSIONS: Rate of vertebral collapse despite PV was influenced by vertebra-specific characteristics and by cement injection quality. Vertebrae with a SINS of ≤9 and with homogeneous cement filling had a lower incidence of collapse.

Reporting of paediatric osteoporotic vertebral fractures in Duchenne muscular dystrophy and potential impact on clinical management: the need for standardised and structured reporting.

BACKGROUND: In boys with Duchenne muscular dystrophy (DMD), initiation of bisphosphonate is recommended upon identification of moderate or severe vertebral fractures, even if asymptomatic. Clear radiological reporting is important for consistency of clinical interpretation and management. OBJECTIVES: To audit radiology reports of spine imaging for vertebral fracture assessment in DMD, and assess potential impact on diagnosis and management. MATERIALS AND METHODS: Lateral thoracolumbar spine imaging (71 lateral spine radiographs and 13 lateral dual energy absorptiometry spine image) in 84 boys with DMD performed across two centres. Anonymised radiology reports by paediatric radiologists were circulated to two neuromuscular clinicians and two endocrinologists. Clinicians determined if there was vertebral fracture, no vertebral fracture, or unclear interpretation. Endocrinologists also determined if bisphosphonate was indicated. A single observer (a clinician with expertise in vertebral fracture assessment) performed vertebral fracture assessment in 37 images and re-reported using a structured format. Structured reports were re-circulated to the four clinicians to re-evaluate the degree of concordance in clinical diagnosis of vertebral fracture and treatment decisions with bisphosphonate. RESULTS: The term "fracture" was used in 25/84 (30%) radiology reports and only in 8/43 (19%) with description of vertebral body abnormalities. Fracture grading was included in 7/43 (16%) radiology reports. Diagnostic concordance by the clinicians was noted in 36/84 (43%). Unclear interpretation was noted in 22% to 51% based on radiology reports. No unclear interpretation was noted with structured reports. Complete diagnostic (37/37, 100%) and treatment (37/37, 100%) concordance was noted with the structured reports, whereas complete diagnostic and treatment concordance was noted in only 16/37 (43%) and 17/37 (46%) of the radiology reports, respectively. CONCLUSION: Only a third of radiology reports of spine imaging in DMD explicitly used the terminology "fracture". Grading was only noted in a small percentage. Variability in diagnostic interpretation by clinicians may lead to differing management plans. As identification of vertebral fracture is a trigger for treatment, developing reporting guidelines for paediatric vertebral fracture assessment will improve care. A structured template should be introduced for radiological reporting of paediatric vertebral fracture assessment.

Age-dependent gender differences in the diagnosis and treatment of osteoporosis during hospitalization in patients with fragility fractures.

BACKGROUND: There is a gender difference in the acceptance of osteoporosis diagnosis and treatment in patients after fragility fractures, but this difference is rarely assessed during hospitalization, and it is unclear whether these differences are age-dependent. This study aimed to evaluate the differences between male and female fragility fracture patients of different age groups who received the diagnosis and treatment of osteoporosis during hospitalization. METHODS: 31,265 fragility fracture patients aged ≥ 50 years from the Fragility Fracture Management Database in a high-volume orthopedic hospital from December 2019 to February 2023 were included in this study. We compared the differences in the rates of men and women with fragility fracture who received the measurement of bone mineral density (BMD) and bone metabolism biochemical markers (BMBMs) and treatment with anti-osteoporosis medications (AOMs), and follow-up to the internal medicine clinic within 3 months after discharge, across all age groups and across different age stages (50-59, 60-69, 70-79, and ≥ 80 years). RESULTS: The detection rates of female patients receiving BMD and BMBMs during hospitalization were 31.88% and 5.30%, respectively, compared with 22.23% and 2.69% for men. The rate of receiving any AOMs treatment was 44.63% for women and 31.60% for men. The follow-up rate of returning to the internal medicine clinic within 3 months after discharge was 9.79% for women compared to 3.00% for men. There was a significant difference between males compared to females (P < 0.0001). Analysis of patients by different age group revealed that differences in the diagnosis and treatment of osteoporosis were found only in patients under 80 years of age, while gender differences in the return to the internal medicine clinic for follow-up after discharge were present in all age groups. CONCLUSIONS: Gender differences present in osteoporosis management in patients with fragility fracture during hospitalization, especially for patients under 80 years of age. This finding suggests that orthopedic surgeons neglect to manage osteoporosis in male patients with fragility fracture during hospitalization.

Effect of bedside health education for elderly patients with fragility fracture by specialist physicians on the diagnosis and treatment of osteoporosis during hospitalization and the visiting rate to osteoporosis clinic after discharge in a high-volume orthopedic hospital.

We retrospectively analyzed 12,999 elderly patients with fragility fracture and found that the detection rate of bone mineral density (BMD) and bone turnover markers (BTMs), the treatment rate of osteoporosis, and the visiting rate to the osteoporosis specialist clinic after discharge are significantly enhanced in fragility fracture patients after receiving health education on osteoporosis-related knowledge during hospitalization. PURPOSE: To observe the effect of health education on the diagnosis and treatment of osteoporosis during hospitalization and the rate of come back to osteoporosis clinic after discharge in elderly patients with fragility fracture. METHODS: A retrospective analysis was performed on 12,999 elderly patients with fragility fracture admitted to Xi'an Honghui Hospital from March 2021 to December 2022. The patients were divided into the health education group and the non-health education group according to whether they received health education on osteoporosis-related knowledge during hospitalization. The diagnosis and treatment of osteoporosis during hospitalization and the outpatient treatment of osteoporosis after discharge were compared between the two groups. RESULTS: Among the 7784 patients in the health education group, 4551 (58.47%) received BMD test, 798 (10.25%) received BTMs test, 3990 (51.26%) received anti-osteoporosis medications (AOMs) treatment, and 1232 (15.83%) came back to the osteoporosis specialist clinic after discharge. Among the 5215 patients in the non-health education group, 681 (13.06%) received BMD test, 6 (0.12%) received BTMs test, 2071 (39.71%) received AOMs treatment, and 440 (8.44%) came back to the osteoporosis specialist clinic within one month after discharge. CONCLUSION: The education of osteoporosis-related knowledge for patients with fragility fracture contribute to enhance the detection rate of BMD and BTMs and the treatment rate of osteoporosis during hospitalization, and increase the rate of coming back to the osteoporosis clinic after discharge.

Targeted optimum care approach for osteoporotic fragility fractures: tailored strategy based on risk stratification to reduce incidents of falls-an initiative by the Egyptian Academy of bone health based on the FLS national register.

Since falling is the third cause of chronic disability, a better understanding of the frequency, severity, and risk factors of falls across diagnostic groups is needed to design and implement customized, effective fall prevention, and management programs for these individuals, particularly those at risk of sustaining a fragility fracture. OBJECTIVE: (1) To assess the incidence of falls among osteoporotic patients with fragility fractures. (2) To evaluate the potential for stratifying the people at risk of falling in bone health setting aiming to provide targeted optimum care for them. METHODS: This was a multi-center, cross-sectional, observational study. Both men and postmenopausal women, admitted with an osteoporotic fracture (whether major osteoporosis or hip fracture), were consecutively recruited for this work and managed under Fracture Liaison Service. All the patients were assessed for their Fracture risk (FRAX), falls risk (FRAS), and sarcopenia risk (SARC-F) as well as functional disability (HAQ). Blood tests for bone profile as well as DXA scan were offered to all the patients. RESULTS: Four hundred five patients (121 males, 284 females) were included in this work. Mean age was 70.1 (SD = 9.2) years. The incidence of falls was 64.9%. The prevalence of falls was high (64.8%) in the patients presenting with major osteoporosis fractures and in those with hip fractures (61.8%). The prevalence of fragility fractures was positively correlated with HAQ score and the SARC-F score (p = 0.01 and 0.021 respectively). Falls risk score was positively correlated with FRAX score of major osteoporotic fractures, HAQ score, and SARC-F score (p = 0.01, 0.013, and 0.003 respectively). Seventy percent of the osteopenia patients who sustained fragility fracture had high falls risk and/or SARC-F score. CONCLUSION: This study highlighted the importance of falls risk stratification in osteoporotic patients presenting with fragility fractures. Identification of the patients at increased risk of falls should be a component of the standard practice.

Higher-intensity ultrasound accelerates fracture healing via mechanosensitive ion channel Piezo1.

Osteoporosis-related fractures are a major public health problem. Mechanobiological stimulation utilizing low-intensity pulsed ultrasound (LIPUS) is the most widely accepted modality for accelerating fracture healing. However, recent evidence has demonstrated the ineffectiveness of LIPUS, and the biophysical mechanisms of ultrasound-induced bone formation also remain elusive. Here, we demonstrate that ultrasound at a higher intensity than LIPUS effectively accelerates fracture healing in a mouse osteoporotic fracture model. Higher-intensity ultrasound promoted chondrogenesis and hypertrophic differentiation of chondrocytes in the fracture callus. Higher-intensity ultrasound also increased osteoblasts and newly formed bone in the callus, resulting in accelerated endochondral ossification during fracture healing. In addition, we found that accelerated fracture healing by ultrasound exposure was attenuated when the mechanosensitive ion channel Piezo1 was inhibited by GsMTx4. Ultrasound-induced new bone formation in the callus was attenuated in fractured mice treated with GsMTx4. Similar results were also confirmed in a 3D osteocyte-osteoblast co-culture system, where osteocytic Piezo1 knockdown attenuated the expression of osteoblastic genes after ultrasound exposure. Together these results demonstrate that higher-intensity ultrasound than clinically used LIPUS can accelerate endochondral ossification after fractures. Furthermore, our results suggest that mechanotransduction via Piezo1 mediates ultrasound-stimulated fracture healing and bone formation.

Bone Homeostasis Modulating Orthopedic Adhesive for the Closed-Loop Management of Osteoporotic Fractures.

Patients with osteoporotic fractures often require effective fixation and subsequent bone repair. However, currently available materials are often limited functionally, failing to improve this cohort's outcomes. Herein, kaempferol-loaded mesoporous bioactive glass nanoparticles (MBGNs)-doped orthopedic adhesives are prepared to assist osteoporotic fracture fixation and restore dysregulated bone homeostasis, including promoting osteoblast formation while inhibiting osteoclastic bone-resorbing activity to synergistically promote osteoporotic fracture healing. The injectability, reversible adhesiveness and malleable properties endowed the orthopedic adhesives with high flexibility and hemostatic performance to adapt to complex clinical scenarios. Moreover, Ca2+ and SiO4 4- ions released from MBGNs can accelerate osteogenesis via the PI3K/AKT pathway, while kaempferol mediated osteoclastogenesis inhibition and can slow down the bone resorption process through NF-κB pathway, which regulated bone regeneration and remodeling. Importantly, implementing the orthopedic adhesive is validated as an effective closed-loop management approach in restoring the dysregulated bone homeostasis of osteoporotic fractures.

Disparities in the Epidemiology and Management of Fragility Hip Fractures.

PURPOSE OF REVIEW: The purpose of this review is to synthesize the recently published scientific evidence on disparities in epidemiology and management of fragility hip fractures. RECENT FINDINGS: There have been a number of investigations focusing on the presence of disparities in the epidemiology and management of fragility hip fractures. Race-, sex-, geographic-, socioeconomic-, and comorbidity-based disparities have been the primary focus of these investigations. Comparatively fewer studies have focused on why these disparities may exist and interventions to reduce disparities. There are widespread and profound disparities in the epidemiology and management of fragility hip fractures. More studies are needed to understand why these disparities exist and how they can be addressed.

Prediction of Progressive Collapse in Osteoporotic Vertebral Fractures Using Conventional Statistics and Machine Learning.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The objective of this study was to determine prognostic factors for the progression of osteoporotic vertebral fracture (OVF) following conservative treatment. SUMMARY OF BACKGROUND DATA: Few studies have evaluated factors associated with progressive collapse (PC) of OVFs. Furthermore, machine learning has not been applied in this context. MATERIALS AND METHODS: The study involved the PC and non-PC groups based on a compression rate of 15%. Clinical data, fracture site, OVF shape, Cobb angle, and anterior wedge angle of the fractured vertebra were evaluated. The presence of intravertebral cleft and the type of bone marrow signal change were analyzed using magnetic resonance imaging. Multivariate logistic regression analysis was performed to identify prognostic factors. In machine learning methods, decision tree and random forest models were used. RESULTS: There were no significant differences in clinical data between the groups. The proportion of fracture shape ( P <0.001) and bone marrow signal change ( P =0.01) were significantly different between the groups. Moderate wedge shape was frequently observed in the non-PC group (31.7%), whereas the normative shape was most common in the PC group (54.7%). The Cobb angle and anterior wedge angle at diagnosis of OVFs were higher in the non-PC group (13.2±10.9, P =0.001; 14.3±6.6, P <0.001) than in the PC group (10.3±11.8, 10.4±5.5). The bone marrow signal change at the superior aspect of the vertebra was more frequently found in the PC group (42.5%) than in the non-PC group (34.9%). Machine learning revealed that vertebral shape at initial diagnosis was a main predictor of progressive vertebral collapse. CONCLUSION: The initial shape of the vertebra and bone edema pattern on magnetic resonance imaging appear to be useful prognostic factors for progressive collapse in osteoporotic vertebral fractures.

Tetrahedral Framework Nucleic Acids Promote Senile Osteoporotic Fracture Repair by Enhancing Osteogenesis and Angiogenesis of Callus.

Senile osteoporotic fracture has aroused increasing attention due to high morbidity and mortality. However, to date, there is no effective therapeutic approach available. Senile osteoporosis is characterized by impaired osteogenesis and angiogenesis, osteoporotic fracture repair could also be promoted by enhancing osteogenesis and angiogenesis. Tetrahedral framework nucleic acids (tFNAs) are a multifunctional nanomaterial that have recently been extensively used in biomedical fields, which could enhance osteogenesis and angiogenesis in vitro. Therefore, we applied tFNAs to intact and femoral fractural senile osteoporotic mice, respectively, to evaluate the effects of tFNAs on senile osteoporosis and osteoporotic fracture repair regarding the osteogenesis and angiogenesis of the callus at the early healing stages and to initially explore the potential mechanism. The outcomes showed that tFNAs had no significant effects on the osteogenesis and angiogenesis of the femur and mandible in intact senile osteoporotic mice within 3 weeks after tFNA treatment, while tFNAs could promote osteogenesis and angiogenesis of callus in osteoporotic fracture repair, which may be regulated by a FoxO1-related SIRT1 pathway. In conclusion, tFNAs could promote senile osteoporotic fracture repair by enhancing osteogenesis and angiogenesis, offering a new strategy for the treatment of senile osteoporotic fracture.

Trabecular Bone Score Vertebral Exclusions Affect Risk Classification and Treatment Recommendations: The Manitoba Bmd Registry.

Lumbar spine trabecular bone score (TBS), a texture measure derived from spine dual-energy x-ray absorptiometry (DXA) images, is a bone mineral density (BMD)-independent risk factor for fracture. Lumbar vertebral levels that show structural artifact are excluded from BMD measurement. TBS is relatively unaffected by degenerative artifact, and it is uncertain whether the same exclusions should be applied to TBS reporting. To gain insight into the clinical impact of vertebral exclusion on TBS, we examined the effect of lumbar vertebral exclusions in routine clinical practice on tertile-based TBS categorization and TBS adjusted FRAX-based treatment recommendations. The study population consisted of 71,209 individuals aged 40 years and older with narrow fan-beam spine DXA examinations and retrospectively-derived TBS. During BMD reporting, 34.3% of the scans had one or more vertebral exclusions for structural artifact. When TBS was derived from the same vertebral levels used for BMD reporting, using fixed L1-L4 tertile cutoffs (1.23 and 1.31 from the McCloskey meta-analysis) reclassified 17.9% to a lower and 6.5% to a higher TBS category, with 75.6% unchanged. Reclassification was reduced from 24.4% overall to 17.2% when level-specific tertile cutoffs from the software manufacturer were used. Treatment reclassification based upon FRAX major osteoporotic fracture probability occurred in 2.9% overall, but in 9.6% of those with baseline risk ≥15%. For treatment based upon FRAX hip fracture probability, reclassification occurred in 3.4% overall, but in 10.4% in those with baseline risk ≥2%. In summary, lumbar spine TBS measurements based upon vertebral levels other than L1-L4 can alter the tertile category and treatment recommendations based upon TBS-adjusted FRAX calculation, especially for those close to or exceeding the treatment cut-off. Manufacturer level-specific tertile cut-offs should be used if vertebral exclusions are applied.

The influence of osteoporotic vertebral fractures on global sagittal alignment in elderly patients: a systematic review and meta-analysis.

BACKGROUND: Thoracic kyphosis, or loss of lumbar lordosis, is often equated with osteoporosis because vertebral fractures are assumed to be a major causative factor, in addition to degeneration related to age. Despite the few studies aiming to measure the natural change in global sagittal alignment (GSA) that occurs with advancing age, the overall effect of conservatively managed osteoporotic vertebral compression fractures (OVCF) on the GSA in the elderly remains poorly understood. OBJECTIVE: To systematically evaluate the relevant literature regarding the influence of OVCF on the GSA compared to patients of similar age without fractures using the following radiological parameters: Pelvic Incidence (PI), Pelvic Tilt (PT), Lumbar Lordosis (LL), Thoracic Kyphosis (TK), Sagittal Vertical Axis (SVA) and Spino-sacral Angle (SSA). METHODS: A systematic review of the English language literature dating up until October 2022, was undertaken utilizing the PRISMA guidelines. RESULTS: Of a total of 947 articles, 10 studies met the inclusion criteria (4 Level II, 4 level III and 2 level IV evidence) and were subsequently analyzed. Overall, 584 patients (8 studies) of mean age 73.7 years (69.3-77.1) had acute OVCF of one or more vertebra that were managed conservatively. The male to female ratio was 82:412. Five studies mentioned the number of fractured vertebrae, with a total of 393 in 269 patients (average of 1.4 fractured vertebrae per patient). Their pre-operative radiological parameters on standing X-rays showed a mean PI of 54.8°, PT 24°, LL 40.8°, TK 36.5°, PI-LL 14°, SVA 4.8 cm, and SSA 115°. In addition, 437 patients were used as a control group with osteoporosis without fractured vertebrae, (6 studies) with an average age of 72.4 years (67-77.8) and male to female ratio of 96:210 (5 studies). They all had upright X-rays to assess their global sagittal alignments. Radiological parameters showed an average PI of 54.3°, PT 17.3°, LL 43.4°, TK 31.25°, PI-LL 10.95°, SVA 1.27 cm and SSA 125°. A statistical analysis comparing the OVCF group with the control group (4 studies), showed a significant increase in PT of 5.97° (95%CI 2.63, 9.32; P < 0.0005), a significant increase in TK by 8.28° (95%CI 2.15, 14.4; P < 0.008), an increase in PI-LL by 6.72° (95%CI 3.39, 10.04; P < 0.0001), an increase in SVA by 1.35 cm (95%CI 0.88, 1.83; P < 0.00001), and a decrease in SSA by 10.2° (95%CI 10.3, 23.4; P < 0.00001). CONCLUSION: Osteoporotic vertebral compression fractures managed conservatively appear to be a significant causate factor of global sagittal imbalance.

Subsequent Domino Osteoporotic Vertebral Fractures Adversely Affect Short-Term Health-Related Quality of Life: A Prospective Multicenter Study.

Background and Objectives: Conservative treatment is the gold standard for acute osteoporotic vertebral fractures (AOVFs). However, the treatment strategy for multiple AOVFs remains unknown. We conducted a prospective study using magnetic resonance imaging (MRI) to investigate how rapidly subsequent osteoporotic vertebral fractures (OVFs) occur as domino OVFs within 3 months. This study aimed to assess the incidence and impact of domino OVFs on quality of life (QOL) following conservative treatment for initial AOVFs. Materials and Methods: A prospective multicenter cohort study was conducted at eight hospitals. The included patients were those with AOVFs occurring within 3 weeks, aged >60 years, and diagnosed using MRI. All patients were treated conservatively and underwent MRI after 3 months. Subsequent domino OVFs were defined as newly occurring OVFs within 3 months. Patient characteristics, types of conservative treatment, and patient-reported outcomes, including a visual analogue scale (VAS), the Oswestry disability index (ODI), and the Japanese Orthopaedic Association back pain evaluation questionnaire (JOABPEQ), were evaluated and compared between the domino OVF and non-domino OVF groups. Results: A total of 227 patients were analyzed. The mean age was 80.1 ± 7.3 years and 78% were female. Subsequent domino OVFs were observed in 31 (13.6%) patients within 3 months. An increasing number of prevalent OVFs were significantly associated with domino OVFs (p = 0.01). No significant differences in bone mineral density, type of brace, and anti-osteoporosis medications were found between the two groups. The JOABPEQ (excluding social function), ODI, and VAS were significantly improved after 3 months. Patients with domino OVFs at 3 months had poorer JOABPEQ social life function, ODI, and VAS than those with non-domino OVFs. Conclusions: In this study, the incidence of domino OVFs was 13.6% within 3 months. Domino OVFs had a negative impact on QOL at 3 months and were associated with prevalent OVFs.
