RESUMO
The frequency of osteoporotic vertebral fractures in the clinical routine is increasing due to the demographic change. They are the most frequent fractures associated with osteoporosis and affect an especially morbid and vulnerable group of patients. These fractures often occur after minor trauma or spontaneously. Pain is the predominant symptom, whereas mechanical stability is mostly sufficient, in comparison to vertebral fractures after high-energy trauma, and is not a predominant indication for surgery. These fractures can be described using the classification for fractures associated with osteoporosis and the corresponding treatment recommendations are guided by them. Besides the specific treatment of osteoporotic vertebral fractures, a holistic treatment of patients taking pre-existing comorbidities into consideration is decisive. A mobilization as quickly as possible and treatment of the underlying osteoporosis are important to prevent further fractures.

BACKGROUND: Injectable bone cement is commonly used in clinical orthopaedics to fill bone defects, treat vertebral compression fractures, and fix joint prostheses during joint replacement surgery. Poly(propylene fumarate) (PPF) has been proposed as a biodegradable and injectable alternative to polymethylmethacrylate (PMMA) bone cement. Recently, there has been considerable interest in two-dimensional (2D) black phosphorus nanomaterials (BPNSs) in the biomedical field due to their excellent photothermal and osteogenic properties. In this study, we investigated the biological and physicochemical qualities of BPNSs mixed with PPF bone cement created through thermal cross-linking. METHODS: PPF was prepared through a two-step process, and BPNSs were prepared via a liquid phase stripping method. BP/PPF was subsequently prepared through thermal cross-linking, and its characteristics were thoroughly analysed. The mechanical properties, cytocompatibility, osteogenic performance, degradation performance, photothermal performance, and in vivo toxicity of BP/PPF were evaluated. RESULTS: BP/PPF exhibited low cytotoxicity levels and mechanical properties similar to that of bone, whereas the inclusion of BPNSs promoted preosteoblast adherence, proliferation, and differentiation on the surface of the bone cement. Furthermore, 200 BP/PPF demonstrated superior cytocompatibility and osteogenic effects, leading to the degradation of PPF bone cement and enabling it to possess photothermal properties. When exposed to an 808-nm laser, the temperature of the bone cement increased to 45-55 °C. Furthermore, haematoxylin and eosin-stained sections from the in vivo toxicity test did not display any anomalous tissue changes. CONCLUSION: BP/PPF exhibited mechanical properties similar to that of bone: outstanding photothermal properties, cytocompatibility, and osteoinductivity. BP/PPF serves as an effective degradable bone cement and holds great potential in the field of bone regeneration.

BACKGROUND: Postmenopausal women face a heightened risk of developing new vertebral compression fractures (NVCFs) following percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fractures (OVCFs). This study aimed to develop and validate a visual nomogram model capable of accurately predicting NVCF occurrence post-PKP to optimize treatment strategies and minimize occurrence. METHODS: This retrospective study included postmenopausal women diagnosed with OVCF who underwent PKP at the Affiliated Hospital of Shandong University of Traditional Chinese Medicine between January 2016 and January 2021. Patient data, including basic information, surgical details, imaging records, and laboratory findings, were collected. The patients were categorized into two groups based on NVCF occurrence within 2 years post-PKP: the NVCF group and the non-NVCF group. Following the utilization of least absolute shrinkage and selection operator (LASSO) regression for feature selection, a nomogram was constructed. Model differentiation, calibration, and clinical applicability were evaluated using receiver operating characteristic (ROC), calibration, and decision (DCA) curve analyses. RESULTS: In total, 357 patients were included in the study. LASSO regression analysis indicated that cement leakage, poor cement diffusion, and endplate fracture were independent predictors of NVCF. The nomogram demonstrated excellent predictive accuracy and clinical applicability. CONCLUSIONS: This study used LASSO regression to identify three independent predictors of NVCF and developed a predictive model that could effectively predict NVCF occurrence in postmenopausal women. This simple prediction model can support medical decision-making and is feasible for clinical practice.

OBJECTIVE: To explore the clinical efficacy of percutaneous vertebroplasty(PVP) combined with nerve block in the treatment of lumbar osteoporotic vertebral compression fractures under the guidance of traditional chinese medicine "theory of equal emphasis on muscle and bone". METHODS: Total of 115 patients with lumbar osteoporotic vertebral compression fractures were treated by percutaneous vertebroplasty from January 2015 to March 2022, including 51 males and 64 females, aged 25 to 86 (60.5±15.9) years. Among them, 48 cases were treated with PVP operation combined with erector spinae block and joint block of the injured vertebral articular eminence (intervention group), and 67 cases were treated with conventional PVP operation (control group). The visual analogue scale(VAS) and Oswestry disability index(ODI) before operation, 3 days, 1 month and 6 months after operation between two groups were evaluated. The operation time, number of punctures and intraoperative bleeding between two groups were compared. RESULTS: The VAS and ODI scores of both groups improved significantly after operation compared with those before operation(P<0.05). Moreover, the VAS and ODI scores of 3 days and 1 month after operation of the intervention group improved more significantly than that of the control group(P<0.05). The difference of VAS and ODI scores before operation and 6 months after operation between two groups had no statistical significances(P>0.05). There was no statistically significant difference in the number of punctures and intraoperative bleeding between the two groups (P>0.05). CONCLUSION: Based on the theory of "equal emphasis on muscles and bones", PVP combined with nerve block can effectively relieve paravertebral soft tissue spasm and other "muscle injuries", which can significantly improve short-term postoperative low back pain and lumbar spine mobility compared to conventional PVP treatment, and accelerate postoperative recovery, resulting in satisfactory clinical outcomes.

OBJECTIVE: Recompression of augmented vertebrae (RCAV) is often seen after percutaneous kyphoplasty (PKP), especially at the thoracolumbar junction. The authors aimed to develop and validate a risk prediction model (nomogram) for RCAV and to evaluate the efficacy of a modified puncture technique for RCAV prevention after PKP for thoracolumbar osteoporotic vertebral fractures (OVFs). METHODS: Patients who underwent PKP for single thoracolumbar OVFs (T10-L2) between January 2016 and October 2020 were reviewed and followed up for at least 2 years. All patients were randomly divided into a training group (70%) and a validation group (30%). Relevant potential data affecting recompression were collected. Predictors were screened by using binary logistic regression analysis to construct the nomogram. Calibration and receiver operating characteristic curves were used to evaluate the consistency of the prediction models. Finally, the efficacy of the modified puncture technique for prevention of RCAV in OVF patients with a preoperative intravertebral cleft (IVC) was further demonstrated through binary logistic regression analysis. RESULTS: Overall, 394 patients were included and 116 of them (29.4%) sustained RCAV. The independent risk factors included decreased bone mineral density, lower level of serum 25-hydroxy vitamin D3, larger C7-S1 sagittal vertical axis (SVA), preoperative IVC, and solid-lump cement distribution. The area under the curve (AUC) of the prediction model was 0.824 in the training group and 0.875 in the validation group patients. The calibration curve indicated the predictive power of this nomogram, with the preoperative IVC having the highest prediction accuracy (AUC 0.705). The modified puncture technique significantly reduced the incidence of RCAV by enhancing bone cement distribution into a sufficiently diffused distribution in OVF patients with preoperative IVC. CONCLUSIONS: The nomogram prediction model had satisfactory accuracy and clinical utility for identification of patients at low and high risk of postoperative RCAV. Patients at high risk of postoperative RCAV might benefit from the target puncture technique and vitamin D supplementation as well as effective antiosteoporotic therapies.

Context: Associations between genes and diseases manifest as the influence of gene expression on disease development as well as the impact of variations in the disease-related genes themselves. It's important to determine the genetic variations that can lead to compressed fractures of osteoporotic, thoracic lumbar vertebrae to develop personalized clinical methods to prevent or delay the disease's development. Objective: The study intended to explore the correlations between the gene polymorphisms and gene expressions of the interleukin-6 (IL-6) gene and the transforming growth factor-beta (TGF-ß) gene and osteoporotic, thoracolumbar, vertebral compression fracture. Design: The research team performed an observational study using data from medical records. Setting: The study took place at Xuzhou Medical University in Xuzhou, China. Participants: Participants were 200 patients with an osteoporotic, thoracolumbar, vertebral compression fracture who had been admitted to the hospital at the university between 2019 and 2021 prior to the study and 200 healthy people The research team divided the participants into two groups. The patients became participants in the disease group, and the healthy individuals became participants in the control group. Outcome Measures: The research team: (1) collected peripheral blood from the two groups, (2) extracted genomic deoxyribonucleic acids (DNAs) from karyocytes, (3) examined the IL-6 and TGF-ß gene polymorphisms, and (4) analyzed and correlated participants' clinical data with the gene polymorphisms and expressions. The team used a quantitative polymerase chain reaction (qPCR) to examine the expression levels of IL-6 and TGF-ß. Results: Compared to the control group, the disease group: (1) had allele distributions that were significantly different at the rs2069829 locus of the IL-6 gene (P < .001) and at the rs3087453 of the TGF-ß gene (P = .004); (2) had significantly higher frequencies of allele T at the rs2069829 locus of the IL-6 gene and of allele G at the rs3087453 locus of the TGF-ß gene; (3) had genotype distributions that were significantly different at the rs2069829 locus (P < .001) and the rs2069857 locus (P = .048) of the IL-6 gene and at the rs3087453 locus (P < .001) of the TGF-ß gene; (4) had frequencies that were significantly higher of the TT genotype at the rs2069829 locus, the CC genotype at the rs2069857 locus, and the GC genotype at the rs3087453 locus of the IL-6 gene and the TGF-ß gene; (5) had dominant models that were significantly different at the rs2069829 locus of the IL-6 gene (P = .009) and at rs3087453 locus of the TGF-ß gene (P = .026) and had a recessive model that was significantly different at the rs2069857 locus of the IL-6 gene (P = .040); (6) had significantly different haplotypes CC (P < .001) and TC (P < .001) at the rs2069829 locus and the rs2069857 locus of the IL-6 gene and a significantly different haplotype AC (P = .011) at the rs1800469 locus and the rs3087453 locus of the TGF-ß gene; (7) had an IL-6 gene polymorphism at the rs2069857 locus that was related to the expression of the IL-6 gene (P < .05) and an expression of the IL-6 gene for participants with the AA genotype that was significantly lower than for other genotypes; (8) had a TGF-ß gene polymorphism at the rs1800469 locus that was associated with the expression of the TGF-ß gene (P < .05), and an expression for participants with the GG genotype that was significantly higher than for other genotypes; (9) had an IL-6 gene polymorphism at the rs2069857 locus with an overt correlation with the genotype of osteoporotic, thoracolumbar, vertebral compression fracture (P < .001). Also, participants in the disease group with the genotype CC mainly had type 2 and 3 fractures, while those with genotype AA primarily had type 0 and 1 fractures. Conclusions: IL-6 and TGF-ß gene polymorphisms and expressions are significantly related to osteoporotic, thoracolumbar, vertebral compression fracture.

Context: With the rapidly aging population globally, osteoporosis (OP) has become a major public health problem, and fracture is a common complication of OP. Older adults, especially postmenopausal women, have a higher incidence of OP. Objective: The study intended to analyze the clinical information, epidemiological characteristics, treatments, and follow-up results of patients with osteoporotic fractures (OPFs) in adults over 65 years old, to provide data support for the prevention, treatment, and use of OPF focus groups in clinical practice. Design: The research team performed a retrospective analysis using electronic medical records and related imaging data of patients. Setting: The study took place at Hebei General Hospital in Hebei, China. Participants: Participants were 387 patients over 65 years old with osteoporotic fractures who had been admitted to the hospital between July 2012 and July 2018. Outcome Measures: The research team recorded participants' ages, genders, fracture causes, and fracture sites. The team performed a follow-up analysis on refractures, treatment with anti-osteoporotic drugs, exercise, and survival status within the 3 years after surgery. Results: The study's male-to-female ratio was 1:3.1, and the rate of osteoporotic fracture for females was significantly higher than that of males. The mean age of participants with fractures was 75.6 ± 8.5 years, and most fractures occurred in participants 78 to 85 years old. Of the 387 participants, 169 participants had hip fractures (43.67%); 98 had vertebral compression fractures (25.32%); 51 had distal radius and ulna fractures (13.18%); 42 had proximal humerus fractures (10.85%); and 27 had other fractures (6.98%). The number of women with fractures at each site was greater than the number of men, but the differences weren't statistically significant (P > .05). The main causes of injury were falls (71.58%), and the main place of the occurrence of injury was at home (65.6%). Of the 387 participants, 346 had surgical treatment (89.41%), and the effective rate of surgical treatment was 99.42%. Three years after surgery, the research team followed up with 235 participants, for a follow-up rate of 60.72%. Within the 3 years of the follow-up period, 61 participants had refractures (25.63%), 29 received treatment with regular anti-osteoporotic drugs (12.34%), 36 exercised twice or more a week (15.32%), and 32 had died for various reasons (13.62%). Conclusions: The study preliminarily described the epidemiological characteristics of 387 osteoporotic fractures in adults over 65 years old. More women had fractures than men; the hip was the most common fracture site, and falls were the main cause of injury. Most of the fractures occurred in the place of residence, and the refracture rate was 25.96% at three years after surgery.

Vertebral compression fractures are typical of osteoporosis and their treatment can require the injection of a cement through a minimally invasive procedure to restore vertebral body height. This study reports the development of an injectable calcium sulphate-based composite cement able to stimulate bone regeneration while inhibiting osteoclast bone resorption. To this aim, different types of strontium-containing mesoporous glass particles (Sr-MBG) were added to calcium sulphate powder to impart a pro-osteogenic effect, and the influence of their size and textural features on the cement properties was investigated. Anti-osteoclastogenic properties were conferred by incorporating into poly(lactic-co-glycolic)acid (PLGA) nanoparticles, a recombinant protein able to inhibit osteoclast activity (i.e., ICOS-Fc). Radiopaque zirconia nanoparticles (ZrO2) were also added to the formulation to visualize the cement injection under fluoroscopy. The measured cement setting times were suitable for the clinical practice, and static mechanical testing determined a compressive strength of ca. 8 MPa, comparable to that of human vertebral bodies. In vitro release experiments indicated a sustained release of ICOS-Fc and Sr2+ ions up to 28 days. Overall, the developed cement is promising for the treatment of vertebral compression fractures and has the potential to stimulate bone regeneration while releasing a biomolecule able to limit bone resorption.

INTRODUCTION: Osteoporotic vertebral fractures are a major healthcare problem. Vertebral cement augmentation (VCA) is frequently used as a minimally invasive surgical approach to manage symptomatic fractures. However, there is a potential risk of adjacent segment fracture (ASF), which may require second surgery. The addition of transcutaneous screw-fixation with cement augmentation superior and inferior to the fracture [Hybrid transcutaneous screw fixation (HTSF)] might represent an alternative treatment option to reduce the incidence of ASF. MATERIALS AND METHODS: We retrospectively compared surgery time, hospital stay, intraoperative complication rate and the occurrence of ASF with the need for a surgical treatment in a cohort of 165 consecutive patients receiving either VCA or HTSF in our academic neurosurgical department from 2012 to 2020. The median follow-up was 52.3 weeks in the VCA-group and 51.9 in the HTSF-group. RESULTS: During the study period, 93 patients underwent VCA, and 72 had HTSF. Of all patients, 113 were females (64 VCA; 49 HTSF) and 52 were males (29 VCA; 23 HTSF). The median age was 77 years in both groups. Median surgery time was 32 min in the VCA-group and 81 min in the HTSF-group (p < 0.0001). No surgery-related complications occurred in the VCA-group with two in the HTSF-group (p = 0.19). ASF was significantly higher in the VCA-group compared to HTSF (24 [26%] vs. 8 [11%] patients; p < 0.02). The proportion of patients requiring additional surgery due to ASF was higher in the VCA-group (13 vs. 6%), but this difference was not statistically significant (p = 0.18). Median hospital stay was 9 days in the VCA-group and 11.5 days in the HTSF-group (p = 0.0001). CONCLUSIONS: Based on this single-center cohort study, HTSF appears to be a safe and effective option for the treatment of osteoporotic vertebral compression fractures. Surgical time and duration of hospital stay were longer in the HTSF-group, but the rate of ASF was significantly reduced with this approach. Further studies are required to ascertain whether HTSF results in superior long-term outcomes or improved quality of life.

BACKGROUND: Patients with adrenal Cushing's syndrome (ACS) typically present with central obesity, hirsutism, hypertension, or glucose intolerance, which can be easily identified by a clinical physician. However, recognizing those with subclinical CS or those with less common symptoms and signs is challenging to the subspecialist, which can lead to delayed diagnosis and treatment. We report a case who presented with repeated vertebral fractures in 6 months. Typical physical appearance of CS was not shown so that suspicions were not raised until severe osteoporosis was demonstrated from bone marrow density study. From our case report, endocrine tests and image survey should always be considered in young patients with repeat vertebral fractures. CASE PRESENTATION: A 48-year-old man presented with severe back pain for 3 months. Second and fifth lumbar spine (L2 and L5) vertebral compression fractures were noted from X-ray and magnetic resonance imaging (MRI), and vertebroplasty was performed by orthopedic surgeons. After 1 month, a newly developed compression fracture of the ninth to twelfth thoracic spine and L4-L5 were noted. Severe osteoporosis was noted from the hip bone mineral density test, and he was referred to an endocrinologist for analysis. Serial endocrine tests confirmed hypercortisolism, and subsequent abdomen MRI showed a left adrenal tumor. ACS was diagnosed. Left laparoscopic adrenalectomy was performed, and the patient received cortisol supplement for 12 months. Thereafter, no new fractures were identified. CONCLUSIONS: ACS should be considered and carefully verified in middle-aged adults who present with severe osteoporosis and repeated vertebral compression fracture.

Background: The relationship between a poor nutritional state and the risk of fractures has not been investigated. This study aimed to investigate the ability of the Controlling Nutritional Status (CONUT) and Geriatric Nutritional Risk Index (GNRI) to predict the incidence of subsequent vertebral fracture (SVF) after percutaneous vertebroplasty (PVP). Methods: A total of 307 women and 138 men over 50 years old who underwent PVP for osteoporotic vertebral compression fracture (OVCF) were included. Blood biochemical indexes, body mass index (BMI), bone mineral density (BMD), physical function, and muscle strength were measured at baseline. Cox regression analysis was used to determine whether nutritional state was an independent predictor for SVF. Results: During follow-up, 35 (25.4%) men and 85 (27.7%) women suffered SVF. Patients with SVF had lower BMI, serum albumin levels, GNRI scores, grip strength, lumbar BMD, and Short-Physical Performance Battery (SPPB) scores and higher fall rates and CONUT scores (P < 0.05). Compared with normal nutrition, mild malnutrition was associated with higher risk for SVF (women: HR 2.37, p=0.001, men: HR 2.97, p=0.021 by GNRI; women: HR 2.36, p=0.005, men: HR 3.62, p=0.002 by CONUT) after adjusting for confounding factors. Those with moderate-severe malnutrition also had a higher risk of SVF. Kaplan-Meier analysis showed that poor nutrition state was significantly associated with lower SVF-free survival (P<0.05). The area under curve (AUC) for predicting SVF was 0.65 and 0.73 for the GNRI and 0.67 and 0.66 for the CONUT in men and women, respectively. Conclusion: GNRI and CONUT are simple and effective tools for predicting SVF in patients undergoing PVP. Health management and nutrition supplement after PVP is a potentially effective prevention strategy against SVF.

Introduction: Fractures of the vertebral bodies are a frequent complication of osteoporosis, hospitalization, decline in physical fitness and, in consequence, deterioration in the quality of life. Objective: The aim of the study was assessment of the quality of life according to the QUALEFFO-41 questionnaire in patients who had undergone fractures of the vertebral bodies, and presentation of the relationships between the quality of life, socio-demographic characteristics, and selected factors concerning the state of health. Materials and Method: The study included 243 women with osteoporotic vertebral fractures, and was conducted in the Outpatient Departments for the Treatment of Osteoporosis in the city of Lublin (eastern Poland). For the purposes of the study, the Quality of Life Questionnaire (QUALEFFO-41) and the author's questionnaire were employed, and Spearman's rank correlation coefficient, t-Student test, and Tukey test were used, along with analysis of variance (ANOVA). The level of statistical significance was set at α = 0.05. Results: The quality of life of woman with vertebral compression fractures remains on a mediocre level. Significant relationships were observed between the respondents' quality of life and certain socio-demographic characteristics, duration of the disease, and complaints related with osteoporosis. Conclusions: It is important to implement appropriate therapy and provide comprehensive, holistic care to women after fractures.

The efficacy of acupuncture combined with percutaneous kyphoplasty (PKP) or percutaneous vertebroplasty (PVP) in the treatment of osteoporotic vertebral compression fracture is systematically evaluated. The clinical trials of acupuncture combined with PKP or PVP in the treatment of osteoporotic vertebral compression fracture published before July 2021 are searched in databases of CNKI, WF, VIP, CBM, PubMed, Cochrane Library, and Embase. The information of included studies is extracted, and the quality is assessed by two independent researchers. The meta-analysis is performed by using RevMan 5.3 software. A total of 9 trials are included, involving 851 patients. The experimental results show that the therapeutic effect of acupuncture combined with PKP/PVP in the treatment of osteoporotic vertebral compression fracture (OVCF) is superior to that of PKP/PVP alone, and both the VAS score and ODI score of PKP/PVP combined with ordinary acupuncture or silver needle acupuncture are better than those of the control group one month after the operation. The effect of ordinary acupuncture combined with PKP/PVP on the increase of bone mineral density is better than that of the control group.

Background and Aim: Osteoporotic vertebral compression fractures (OVCFs) are acknowledged to be common fractures, especially in the elderly population. Minimally invasive percutaneous methods of treatment for these fractures such as kyphoplasty (KP) and vertebroplasty (VP) have been valid and effective tools for decreasing clinical problems, which are associated with more beneficial effects compared with traditional methods such as open surgery or conservative treatment. Hence, we conducted the current meta-analysis in order to gather updated evidence for the systematic assessment of clinical and radiographic outcomes of KP compared with VP. Methods: We searched articles published based on the electronic databases, including PubMed, EMBASE, and Cochrane Library. Publications of studies comparing KP with VP in the treatment of OVCFs were collected. After rigorous and thorough review of study quality, we extracted the data on the basis of eligible trials, which analyzed the summary hazard ratios (HRs) of the end points of interest. Results: Our inclusion criteria involved a total of 6 studies. In total, data from 644 patients, 330 who received VP and 284 who received KP, were included in the review. There was no significant difference in either group in terms of visual analog scale (VAS) scores (MD = 0.17; 95% CI, -0.39 to 0.73; P = .56), risk of cement leakage (odds ratio [OR] = 1.31; 95% CI, 0.62 to 2.74; P = .47) or Oswestry Disability Index (ODI) scores (MD = 0.51; 95% CI, -1.87 to 2.88; P = .68). Nevertheless, the injected cement volume (MD = -0.52; 95% CI, -0.88 to -0.15; P = .005) in the VP group was linked to a markedly lower statistically significant trend compared with the KP group. Conclusion: This meta-analysis evaluated acceptable efficacy levels across the involved trials. VP injected cement volume had several advantages in this meta-analysis. Yet, no significant differences were observed in terms of VAS scores, ODI scores, or cement leakage when KP was compared to VP therapy. Given the combined results of our study, the optimal treatment for patients with OVCFs should be determined by further high-quality multicenter randomized controlled trials with longer follow-up and larger sample sizes.

BACKGROUND: Kyphoplasty for osteoporotic vertebral compression fractures (OVCF) is a short but painful intervention. Different anesthetic techniques have been proposed to control pain during kyphoplasty; however, all have limitations. OBJECTIVE: To compare the effectiveness and safety of ultrasound-guided thoracic paravertebral block with local anesthesia for percutaneous kyphoplasty (PKP). METHODS: In this prospective study, non-randomized patients with OVCF undergoing PKP received either ultrasound-guided thoracic paravertebral block (group P) or local anesthesia (group L). Perioperative pain, satisfaction with anesthesia, and complications were compared between the groups. RESULTS: Mean intraoperative (T1-T4) perioperative visual analog scale (VAS) scores were significantly lower in group P than in group L (2 [1-3] vs. 3 [2-4], 2 [2-3] vs. 4 [2-4], 2 [2-3] vs. 5 [3-5], and 3 [2-3] vs. 5 [3-5], respectively; P< 0.05). Investigators' satisfaction scores, patients' anesthesia satisfaction scores, and anesthesia re-administration intention rate were significantly higher in group P than in group L (4 [3-5] vs. 3 [2-4], 2 [2-3] vs. 2 [1-3], 90.63% vs. 69.70%; P< 0.05). There was no significant intergroup difference in complications. CONCLUSIONS: Ultrasound-guided thoracic paravertebral block has similar safety to and better effectiveness than local anesthesia in PKP.

INTRODUCTION: Bone loss is a major issue in patients affected by Duchenne muscular dystrophy (DMD), a rare musculoskeletal disorder, particularly in those treated with glucocorticoids (GCs). We aimed to assess the effectiveness of neridronate in terms of bone mineral density (BMD) changes in this population. METHODS: We retrospectively reviewed the records of patients affected by DMD receiving GCs referred to our outpatient from 2015 to 2020. All patients were treated with an intramuscular (IM) injection of neridronate (25 mg every month). Bone density was measured at the lumbar spine (LS; L1-L4 tract) using dual-energy x-ray absorptiometry (DXA) (GE Lunar), no more than 4 weeks before (T0) and after 1 year from neridronate treatment (T1). RESULTS: Eight boys with DMD were included with a mean age at diagnosis of 4.75 ± 2.81 years. Six of them were non-ambulant and two of them had previous low-trauma fractures (a distal femur fracture and a vertebral compression fracture, respectively). All patients were receiving deflazacort [median duration of therapy 11.5 years (interquartile range 2-25)]. At the DXA evaluation (T0), the mean L1-L4 BMD value was 0.716 ± 0.164 g/cm2. Six patients (75%) showed an L1-L4 Z-score height-adjusted of less than - 2. The mean age of neridronate initiation was 18.87 ± 6.81 years. All patients were supplemented with calcium carbonate and vitamin D at baseline. After 12 months of treatment (T1), the mean L1-L4 BMD value was 0.685 ± 0.190 g/cm2. Seven patients (87.5%) showed an L1-L4 Z-score of less than - 2. Changes in LS BMD and Z-score were not significant between T0 and T1 in our cohort (p = 0.674 and p = 0.208, respectively) as well as among non-ambulant patients with DMD without previous fragility fractures. CONCLUSIONS: In this study, we reported for the first time that neridronate may slow bone loss in GC-treated patients with DMD at 1-year follow-up.

Osteogenesis imperfecta (OI) is a group of heritable disorders affecting bone and other connective tissues. Dominant OI forms are mainly caused by mutations in collagen type I. Patients suffer from skeletal deformities, fractures of long bones and vertebral compression fractures from early childhood onward. Altered collagen structure and excess mineralisation are the main causes for the bone phenotype. The Chihuahua (Chi/+) zebrafish has become an important model for OI. Given that reduced dietary phosphorus (P) intake reduces the bone mineral content and promotes bone matrix formation in teleosts, including zebrafish, we tested whether a low dietary P (LP) intake mitigates the OI phenotype in the Chi/+ model. To answer this question, we characterised the Chi/+ vertebral column phenotype at a morphological, cellular and subcellular level. We present the first description of vertebral compression fractures in Chi/+ and assess the effects of LP diet on the Chi/+ phenotype (Chi/+LP). Compared to untreated Chi/+, two months of LP dietary treatment decreases vertebral deformities in the abdominal region and reduces shape variation of caudal vertebral bodies to a condition more similar to wild type (WT). At the histological level, the osteoid layer, covering the bone at the vertebral body endplates in WT zebrafish, is absent in Chi/+, but it is partially restored with the LP diet. Whole mount-stained specimens and histological sections show various stages of vertebral compression fractures in Chi/+ and Chi/+LP animals. Both Chi/+ and Chi/+LP show abundant osteoclast activity compared to WT. Finally, the ultrastructure analysis of WT, Chi/+ and Chi/+LP shows Chi/+ and Chi/+LP osteoblasts with enlarged endoplasmic reticulum cisternae and a high protein content, consistent with intracellular retention of mutated collagen. Nevertheless, the secreted collagen in Chi/+LP appears better organised concerning fibre periodicity compared to Chi/+. Our findings suggest that a reduced mineral content of Chi/+ bone could explain the lower frequency of vertebral column deformities and the restored shape of the vertebral bodies in Chi/+LP animals. This, together with the improved quality of the bone extracellular matrix, suggests that two months of reduced dietary P intake can alleviate the severe bone phenotype in Chi/+ zebrafish.

BACKGROUND: This study retrospectively analyzed and evaluated the potential correlations of serum calcium, serum phosphorus, and calcium-phosphorus product (Ca-P product) with the incidence of osteoporotic vertebral compression fractures (OVCFs), with the aim of exploring whether the Ca-P product can be used as a serological indicator to predict the risk of OVCFs. METHODS: This study randomly enrolled 400 elderly patients in our hospital with OVCFs and 400 patients with hip and knee arthroplasty due to femoral head necrosis or osteoarthritis from August 2013 to April 2021. Age, sex, past medical history, and admission biochemical indicators, including albumin, blood urea nitrogen, serum creatinine, serum calcium and serum phosphorus, were collected for statistical analysis. RESULTS: Albumin, serum calcium, serum phosphorus, Ca-P product, corrected serum calcium and corrected Ca-P product were lower in the OVCF group than in the non-OVCF group (P < 0.05). Multivariate logistic regression analysis showed that low values of serum calcium, serum phosphorus, Ca-P product, corrected blood calcium, and corrected Ca-P product can all be risk factors for OVCF. The ROC curve showed that the Ca-P product and corrected Ca-P product were effective in predicting the risk of OVCFs. The predictive value of the Ca-P product was the best; the cutoff point was 29.88, the sensitivity was 0.72 and the specificity was 0.62. The cutoff point of the corrected Ca-P product was 30.50, the sensitivity was 0.74, and the specificity was 0.62. CONCLUSION: The Ca-P product and corrected Ca-P product can be used as serological indicators to predict the risk of OVCFs in elderly individuals. Early clinical interventions targeting this risk factor can further reduce the risk of OVCFs. Also, timely and regular testing of the serum calcium and phosphorus level is recommended and encouraged for this group of people.
