Factors influencing further vertebral height loss following percutaneous vertebroplasty in osteoporotic vertebral compression fractures:A 1-year follow-up study

BACKGROUND Osteoporotic vertebral compression fractures(OVCFs)contribute to back pain and functional limitations in older individuals,with percutaneous vertebroplasty(PVP)emerging as a minimally invasive treatment.However,further height loss post-PVP prompts investigation into contributing factors.AIM To investigate the factors associated with further height loss following PVP with cement augmentation in OVCF patients.METHODS A total of 200 OVCF patients who underwent successful PVP between January 2021 and December 2022 were included in this study.“Further height loss”during 1 year of follow-up in OVCF patients with bone edema was defined as a vertical height loss of≥4 mm.The study population was divided into two groups for analysis:The“No Further Height Loss group(n=179)”and the“Further Height Loss group(n=21).”RESULTS In comparing two distinct groups of patients,significant differences existed in bone mineral density(BMD),vertebral compression degree,prevalence of intravertebral cleft(IVF),type of bone cement used,and cement distribution patterns.Results from binary univariate regression analysis revealed that lower BMD,the presence of IVF,cleft distribution of bone cement,and higher vertebral compression degree were all significantly associated with further height loss.Notably,the use of mineralized collagen modified-poly(methyl methacrylate)bone cement was associated with a significant reduction in the risk of further height loss.In multivariate regression analysis,lower BMD and the presence of IVF remained significantly associated with further height loss.CONCLUSION Further height loss following PVP in OVCF patients is influenced by a complex interplay of factors,especially lower BMD and the presence of IVF.These findings underscore the importance of assessing and managing these factors when addressing height loss following PVP in OVCF patients.

Managements of osteoporotic vertebral compression fractures:A narrative review

Osteoporotic vertebral compression fractures(OVCFs)are the most common fragility fracture and significantly influence the quality of life in the elderly.Currently,the literature lacks a comprehensive narrative review of the management of OVCFs.The purpose of this study is to review background information,diagnosis,and surgical and non-surgical management of the OVCFs.A comprehensive search of PubMed and Google Scholar for articles in the English language between 1980 and 2021 was performed.Combinations of the following terms were used:compression fractures,vertebral compression fractures,osteoporosis,osteoporotic compression fractures,vertebroplasty,kyphoplasty,bisphosphonates,calcitonin,and osteoporosis treatments.Additional articles were also included by examining the reference list of articles found in the search.OVCFs,especially those that occur over long periods,can be asymptomatic.Symptoms of acute OVCFs include pain localized to the mid-line spine,a loss in height,and decreased mobility.The primary treatment regimens are pain control,medication management,vertebral augmentation,and anterior or posterior decompression and reconstructions.Pain control can be achieved with acetaminophen or nonsteroidal anti-inflammatory drugs for mild pain or opioids and/or calcitonin for moderate to severe pain.Bisphosphonates and denosumab are the first-line treatments for osteoporosis.Vertebroplasty and kyphoplasty are reserved for patients who have not found symptomatic relief through conservative methods and are effective in achieving pain relief.Vertebroplasty is less technical and cheaper than kyphoplasty but could have more complications.Calcium and vitamin D supplementation can have a protective and therapeutic effect.Management of OVCFs must be combined with multiple approaches.Appropriate exercises and activity modification are important in fracture prevention.Medication with different mechanisms of action is a critical long-term causal treatment strategy.The minimally invasive surgical interventions such as vertebroplasty and kyphoplasty are reserved for patients not responsive to conservative therapy and are recognized as efficient stopgap treatment methods.Posterior decompression and fixation or Anterior decompression and reconstruction may be required if neurological deficits are present.The detailed pathogenesis and related targeted treatment options still need to be developed for better clinical outcomes.

Experimental Study on the Repair Effect of Xianlinggubao Capsule on Osteoporotic Vertebral Compression Fracture in Rabbits

[Objectives]To observe the effect of Xianlinggubao Capsule on osteoporotic vertebral compression fracture(OVCF)in rabbits and the influence mechanism of the repair of fractures.[Methods]Female June age 30 rabbits were randomly divided into control group,model control group and Xianlinggubao group.After bilateral ovariectomy,the model control group and Xianlinggubao group were injected with dexamethasone continuously for 4 weeks,and then the OVCF compound model was established by surgery.The Xianlinggubao group was treated with Xianlinggubao at a dose of 300 mg/(kg·d)for 60 d,while the blank control group and the model control group were treated with the same amount of normal saline for 60 d.The number of blood vessels and the expression of bone morphogenetic protein-2(BMP-2)were detected by immunohistochemical staining and the bone mineral density(BMD)in the callus of the third lumbar fracture area of rabbits was measured.The content of serum phosphorus(P),alkaline phosphatase(ALP)and total calcium(TCa)in rabbit venous blood were measured by automatic biochemical analyzer.The content of vascular endothelial growth factor(VEGF)and platelet-derived growth factor(PDGF)in rabbit venous blood were measured by ELISA kit.[Results]The number of blood vessels and the expression of BMP-2 in the callus of the third lumbar fracture area of rabbits was high in Xianlinggubao group,the content of serum P,ALP,TCa,VEGF and PDGF was obviously increased,BMD was obviously increased,the bone microstructure of the third lumbar vertebrae fracture area of rabbits was basically restored.Compared with the model control group(P<0.05),the difference was statistically significant.[Conclusions]Xianlinggubao Capsule can increase calcium and phosphorus deposition,promote the formation of blood vessels in the fracture area of OVCF in rabbits,and have a strong repair effect on OVCF in rabbits.

Reinforcing effect of calcium sulfate cement bovine bone morphogenetic protein on vertebral in the rabbit model of osteoporosis

Objective:To observe reinforcing effect of calcium sulfate cement(CSC) bovine bone morphogenetic protein(bBMP) on vertebral in the rabbit model of osteoporosis.Methods:A total of 48 New Zealand white rabbits were randomly divided into group Ⅰ(blank control group),groupⅡ(CSC injection group),group Ⅲ(CSC/bBMP injection group) and control group.White rabbit osteoporosis model was established rapidly by using castration mcthod+methylprcdnisolone candidate.After modeling,groups Ⅱ.Ⅲ were given corresponding vertebral body injection material,and 4 animals were sacrificed respectively at 24 h,6 weeks,12 weeks after vertebral plasty.Tissue pathological status,vertebral mineral density and vertebral body bone mechanical strength were observed.Results:Vertebral body structure form was normal in the groups Ⅱand Ⅲ.Trabecular bone coarsens,connection and repair were observed in micro fracture and bone defects,bone trabecular connectivity was superior to group I significantly;vertebral body compression strength in the group I was on the decline,vertebral compression strength in the groups Ⅱ and Ⅲ was on the rise,the largest vertebra.Postoperative BMC and BMD in groups Ⅱand Ⅲ were incresed,and significantly higher than group I after 6 weeks(P<0.05),BMC and BMD in group Ⅲ after 12 weeks were higher than the other three groups.Conclusion:Compound bBMP CSC has good bone induction.It can improve the three-dimensional construction effect for osteoporosis vertebral trabecula,and can significantly improve the vertebral strength,as a vertebral packing material with good application prospect.

Effect of osteoporosis and intervertebral disc degeneration on endplate cartilage injury in rats

Objective:To investigate the effect of osteoporosis and intervertebral disc degeneration on the endplate cartilage injury in rats.Methods:A total of 48 female Sprague Dawley rats(3 months)were randomly divided into Groups A,B,C and D with 12 rats in each group.Osteoporosis and intervertebral disc degeneration composite model,simple degeneration model and simple osteoporosis model were prepared in Groups A,B and C respectively.After modeling,four rats of each group at 12th.18th and 24th week were sacrificed,Intervertebral height of cervical vertebra C6/C7 was measured.Micro-CT was used to image the endplate of cephalic and caudal cartilage at C6/C7 intervertebral disc.Abraded area rate of C6 caudal and C7 cephalic cartilage endplate was calculated,and then C6/C7 intervertebral disc was routinely embedded and sectioned.stained with safranin O to observe histological changes microscopically.Results:At 12,18 and24 weeks,intervertebral disc height of C6/C7 were(0.58±0.09)mm,(0.53±0.04)mm and(0.04±0.06)mm in Group A rats,(0.55±0.05)mm,(0.52±0.07)mm and(0.07±0.05)mm in Group B rats.At 24th week.intervertebral disc height of Group A rats was significantly lower than that of Group B rats(P<0.05);intervertebral disc height of Groups A and B rats at each time point were significantly lower than that of Groups C and D(P<0.05).There was no significantly statistical difference of intervertebral disc height between Groups C and D(P>0.05).At 12 and 18 weeks,the abraded rate of C6 caudal and C7 cephalic cartilage endplate in Group A rats were significantly higher than that in Groups B.C and D rats(P<0.05);the abraded rate in Group B was significantly higher than that in Groups C and D(P>0.05).Microscopic observation of CT showed that ventral defects in C6caudal or C7 cephalic cartilage endplate in Groups A and B appeared after 12 weeks of modeling;obvious cracks were found in front of the C6 and C7 vertebral body,and cartilage defect shown the trend of"repairing"at 18 and 24 weeks after modeling.Conclusions:Intervertebral disc degeneration and osteoporosis can cause damage to the cartilage endplate.Co-existence of these two factors can induce more serious damage to the endplate.which has possitive correlation with intervertebral disc degeneration.Osteoporosis plays a certain role in intervertebral disc degeneration process,and accelerates the degeneration of intervertebral disc in a specific time window.

The impact of endplate fracture on postoperative vertebral height loss and kyphotic deformity during treatment of osteoporotic vertebral compression fractures with balloon kyphoplasty

This retrospective study investigated the impact of endplate fracture on postoperative vertebral height loss and kyphotic deformity in 144 patients with osteoporotic vertebral compression fracture （OVCF）, who received balloon kyphoplasty. Patients were divided into four groups： Group 1 had no superior endplate fracture, Group 2 had fractures on the anterior portion of the superior endplate, Group 3 had fractures on the posterior portion of the superior endplate, and Group 4 had complete superior endplate fractures. Anterior and middle vertebral body height, vertebral compression ratio, vertebral height loss rate, and kyphosis Cobb angle of each patient were measured and visual analogue scale （VAS） and Oswestry disability index （ODI） scores were recorded. The anterior vertebral height and kyphosis deformity of all groups significantly improved after the surgery, whereas substantial anterior vertebral height loss and increased Cobb angle were observed in all patients at the last follow-up. Although the vertebral height loss rate and the Cobb angle in Group 2, 3 and 4 were larger compared with Group 1 at the last follow-up, only the vertebral height loss rate in Group 4 and the increase in the Cobb angle in Group 2 and 4 were statistically different from those in Group 1. The VAS and ODI scores in all groups measured after the surgery and at the last follow-up were significantly lower compared with preoperative scores, but there was no significant difference among these groups. Balloon kyphoplasty significantly improved vertebral fracture height and kyphosis. Vertebral height loss and increased kyphotic deformity were observed in OVCF patients with endplate fractures after the surgery. Postoperative aggravation of kyphosis was observed in Group 2. Furthermore, severe vertebral height loss and increased kyphotic deformity were confirmed in Group 4 after the surgery. Our results suggested that postoperative vertebral height loss and aggravation of kyphosis may be associated with biomechanical changes in the vertebral body caused by endplate fracture. Therefore, surgery should not only restore compressed vertebral body height and correct kyphosis, but also correct the deformity of endplate to achieve an effective treatment of OVCF patients with endplate fracture.

Outcomes of different minimally invasive surgical treatments for vertebral compression fractures:An observational study

BACKGROUND Osteoporosis with vertebral compression fractures is increasingly common in the elderly population.Cement augmentation is one of the effective surgical treatments for these patients.Currently,there are several different types of cement augmentation treatments.No studies have compared the safety and efficacy of different cement augmentation types for the treatment of such fractures;thus,we retrospectively compared vertebroplasty,balloon kyphoplasty,and kyphoplasty with SpineJack or an intravertebral expandable pillar.AIM To compare the postoperative safety and efficacy of each surgical intervention in treating vertebral compression fractures.METHODS We retrospectively analyzed 354 patients with acute vertebral compression fractures,defined as signal changes in the T1 weighted magnetic resonance imaging,and randomly divided the patients into five groups.Their visual analog scale scores for pain,kyphotic angle,average body height,rate of cement leakage,and occurrence of adjacent vertebral compression fractures were followed for 1 year.One-way analysis of variance,the post hoc Bonferroni test,and Fisher exact probability test were used for statistical analyses.RESULTS All pain scores significantly improved 12 mo postoperatively;however,there was no significant difference between the groups(P=0.325).Kyphoplasty with SpineJack significantly reduced the kyphotic angle(P=0.028)and restored the height of the vertebral body(P=0.02).The rate of adjacent compression fractures was the highest in the vertebroplasty group,with a statistically significant difference according to the Fisher exact probability test(P=0.02).The treatment with the lowest cement leakage rate cannot be identified because of the small sample size;however,kyphoplasty with SpineJack,an IVEP,and vesselplasty resulted in lower rates of cement leakage than balloon kyphoplasty and vertebroplasty.CONCLUSION Kyphoplasty with SpineJack has good outcomes in kyphotic angle reduction and body height restoration.Vertebroplasty has the highest cement leakage rate and adjacent compression fracture occurrence.

A Comparative Study of High-viscosity Cement Percutaneous Vertebroplasty vs. Low-viscosity Cement Percutaneous Kyphoplasty for Treatment of Osteoporotic Vertebral Compression Fractures

The clinical effects of two different methods–high-viscosity cement percutaneous vertebroplasty（PVP） and low-viscosity cement percutaneous kyphoplasty（PKP） in the treatment of osteoporotic vertebral compression fractures（OVCFs） were investigated. From June 2010 to August 2013, 98 cases of OVCFs were included in our study. Forty-six patients underwent high-viscosity PVP and 52 patients underwent low-viscosity PKP. The occurrence of cement leakage was observed. Pain relief and functional activity were evaluated using the Visual Analog Scale（VAS） and Oswestry Disability Index（ODI）, respectively. Restoration of the vertebral body height and angle of kyphosis were assessed by comparing preoperative and postoperative measurements of the anterior heights, middle heights and the kyphotic angle of the fractured vertebra. Nine out of the 54 vertebra bodies and 11 out of the 60 vertebra bodies were observed to have cement leakage in the high-viscosity PVP and low-viscosity PKP groups, respectively. The rate of cement leakage, correction of anterior vertebral height and kyphotic angles showed no significant differences between the two groups（P〉0.05）. Low-viscosity PKP had significant advantage in terms of the restoration of middle vertebral height as compared with the high-viscosity PVP（P〈0.05）. Both groups showed significant improvements in pain relief and functional capacity status after surgery（P〈0.05）. It was concluded that high-viscosity PVP and low-viscosity PKP have similar clinical effects in terms of the rate of cement leakage, restoration of the anterior vertebral body height, changes of kyphotic angles, functional activity, and pain relief. Low-viscosity PKP is better than high-viscosity PVP in restoring the height of the middle vertebra.

Vertebral Bone Drilling (Puncture) Attenuates the Acute Pain Due to Vertebral Compression Fractures

Purpose: The Investigational Vertebroplasty Efficacy and Safety Trial (INVEST), a randomized blinded controlled study of Vertebroplasty, demonstrated similar improvements in pain between blinded Vertebroplasty and sham-Vertebroplasty groups. The result from the RCT study suggested that the observed efficacy of the Vertebroplasty procedure, instead of representing the cement-mediated reduction in pain, may relate to the vertebral bone drilling per se. The aim of this study was to demonstrate the effectiveness of pain relief of vertebral bone drilling at the site of painful osteoporotic vertebral compression fractures in the acute phase. Materials and Methods: Twenty-six patients with painful osteoporotic compression fractures underwent the vertebral bone drilling. We assessed primary outcome measures in the NRS pain score and RDQ score at day 0 and 3 following the drilling. Comparisons were made by using Wilcoxon signed rank test. Results: The mean baseline NRS and RDQ score, and the mean NRS and RDQ score at day 3 were 7.3 ± 1.2, 15.7 ± 4.2, 4.6 ± 1.4, 7.3 ± 2.2, respectively. Among the patients, we detected significant improvements in NRS pain score and RDQ score at day 3 following the drilling compared with day 0 (P < 0.001). Conclusion: Vertebral bone drilling at the site of painful vertebral compression fractures alleviated the intractable pain due to osteoporotic vertebral compression fractures.

Do osteoporosis-related vertebral fractures precede hip fractures?

AIM:To evaluate the relationship between a vertebral fracture and a hip fracture in Saudi Arabians with osteoporosis.METHODS:In this retrospective study,154 Saudi Arabian patients with osteoporosis-related hip fractures were analyzed for the presence of a vertebral fracture.Radiographs were retrieved from the IPAC(Image Picture Archiving and Computing)System,an imaging retrieval system,and were reviewed independently by two of the authors,Abid Hussain Gullenpet,and Mir Sadat-Ali,and later reviewed jointly.Patients admitted with proximal hip fracture who were≥50 years and had undergone Thoraco-lumber imaging and a dual energy X-ray absorptiometry(DEXA)scan were included in the study.Patients with a history of significant trauma to the spine and those with a malignancy or connective tissue disorder were excluded from the analysis.RESULTS:Out of 154 patients with hip fractures,78had a fracture of the femoral neck while 76 had an intertrochanteric hip fracture.Of the 111 patients whowere finally included in the study,after applying inclusion and exclusion criteria,76 patients with an average age of 67.28±12 years had no fractures of the spine.Thirty-five patients with an average age of 76.9±14.5years(31.53%)had a total of 49 vertebral fractures.Patients with vertebral fractures were significantly older than those without fractures P<0.001.Overall,24.7%of these patients had an asymptomatic vertebral fracture.Further analysis showed that 11 males(18.96%)and 24 females(45.28%)had suffered a previous asymptomatic vertebral fracture.Interestingly,all women who participated in this study and who presented with a femoral neck fracture had experienced a prior asymptomatic vertebral fracture.CONCLUSION:We recommend that all elderly patients who go to the radiology department for a chest X-ray also have a DEXA scan and a lateral thoracic spine radiograph.

Full-endoscopic spine surgery treatment of lumbar foraminal stenosis after osteoporotic vertebral compression fractures:A case report

BACKGROUND Few reports have described lumbar foraminal stenosis-induced radiculopathy after treatment by full-endoscopic spine surgery(FESS)combined with percutaneous vertebroplasty(PVP)in patients with vertebral compression fractures.We herein report such a case,including the patient’s treatment process and doctor’s surgical experience.CASE SUMMARY A 79-year-old man presented with symptoms of radiculopathy after sustaining L4 vertebral compression fractures.Imaging and physical examination revealed L4 vertebral compression fractures combined with L3/4 Lumbar foraminal stenosis(LFS).The patient’s symptoms were low back pain with pain in the lateral left leg.Although many reports have described radiculopathy induced by osteoporotic vertebral compression fractures,the use of FESS combined with PVP has rarely been reported.This case report indicates that the combination of FESS and PVP is a safe and effective approach for the treatment of LFS-induced radiculopathy after vertebral compression fractures.This minimally invasive technique has great potential to replace traditional lumbar fixation and decompression surgery.Thus,we suggest the continued accumulation of similar cases to discuss the wider application of FESS.CONCLUSION For patients with osteoporotic vertebral compression fracture(OVCF)and LFS,PVP and FESS can be used to restore the vertebral height and reduce the pressure around the intervertebral foramen.Additionally,the combination of FESS and PVP can treat the pain or numbness of the low back and lower limbs and allow for recovery in a short time with excellent postoperative effects.In general,FESS is a good treatment for radiculopathy caused by foraminal stenosis after OVCF.

Diagnosis and Treatment and Infection Protection Strategy of Osteoporotic Vertebral Compression Fractures Minimally Invasive Percutaneous Kyphoplasty Surgery during the Prevention and Control of COVID-19

Background: As the global novel coronavirus pneumonia (NCP) remains severe, elderly people are at high risk for NCP and osteoporotic vertebral compression fractures, with high complications and mortality. How to treat patients and protect medical staff from infection, and at the same time strictly prevent the occurrence of clustered transmission events in the hospital, the establishment of perfect pre-hospital emergency measures and infection prevention and control strategy is the first element to ensure success. Objective: To establish the diagnosis and treatment and infection protection strategy for Osteoporotic vertebral compression fractures (OVCF) patients undergoing minimally invasive percutaneous kyphoplasty (PKP) surgery during the prevention and control of COVID-19, so as to ensure the stable, orderly and safe medical treatment. Methods: A total of 583 OVCF patients were admitted to the First Affiliated Hospital of Hebei North University during the epidemic prevention and control period from January 2020 to July 2022. After urgent and outpatient strict standardized screening, 382 patients met the inclusion criteria, including 112 males and 270 females, aged (70.50 ± 5.49) years. The preoperative visual analogue scale (VAS) score was 6.92 ± 1.86. Preoperative Oswestry disability index (ODI) was 74.67 ± 4.84. The satisfaction rate was (45.89 ± 3.67) %. According to the clinical diagnostic criteria and classification, 367 patients were diagnosed as ordinary OVCF, including 156 cases of mild compression and 226 cases of moderate compression. The clinical classification of 15 patients with OVCF diagnosed as COVID-19 was type I, including 10 cases of mild COVID-19 and 5 cases of common COVID-19. All patients were treated with PKP. Results: All patients were followed up at 1 day, 1 month and 3 months after operation, VAS (2.01 ± 0.56, 0.45 ± 0.11, 0 ± 0), ODI (45.41 ± 4.15, 10.22 ± 2.73, 4.03 ± 1.57) and satisfaction (90.12%, 95.57%, 99.23%) were significantly improved compared with those before operation (p < 0.05), and the original medical diseases were not aggravated. In this group, 15 cases of OVCF diagnosed with COVID-19 were given priority to treat COVID-19 under strict three-level protection in the designated isolation ward. PKP was carried out after the condition was stable, and the areas, items and personnel in contact with patients during the perioperative period must be strictly and thoroughly disinfected. The patient had a good prognosis, no complications, no cross-infection in the hospital, and no infection rate among medical staff. Conclusions: The implementation of the diagnosis and treatment and infection protection strategy for OVCF patients undergoing minimally invasive PKP surgery during the prevention and control of COVID-19 has a guiding role in preventing the spread of infection, improving the cure rate, promoting rapid recovery, reducing complications and reducing mortality.

Clinical Research of Pre-Hospital Emergency Care, Nursing, Infection Prevention and Control for Senile Osteoporotic Vertebral Compression Fracture during Epidemic Period

Background: Novel coronavirus pneumonia (NCP) and osteoporotic vertebral compression fractures (OVCF) are the high incidences of diseases in the elderly. During the epidemic period, if not treated in time, the complications are high and the mortality is high. If we do not pay attention to infection prevention and control in pre-hospital emergency care, it will lead to the first time infection of medical staff and in-hospital cross infection in emergency outpatient receiving area. The correct consideration of both and the establishment of perfect pre-hospital emergency treatment and infection prevention and control synchronous strategy is an important premise to ensure the stable, orderly and safe medical treatment. Objective: To explore the effect of synchronous implementation of pre-hospital emergency care, nursing and infection pre-vention and control for senile OVCF during the epidemic. In order to improve the efficiency of pre-hospital emergency care and prevent the spread of infection. Method: A total of 92 elderly patients with OVCF who received pre-hospital treatment in 18 hospitals in Zhangjiakou City during the epidemic prevention and control period from January 2020 to November 2022 and met the inclusion criteria were selected as research objects, including 24 males and 68 females, aged 65 - 82 (74.2 ± 2.2) years. All patients were associated with concomitant injuries and underlying diseases. All patients in this group underwent predictive pre-hospital rescue and infection prevention and control procedures. Results: All the 92 elderly patients with OVCF received timely pre-hospital treatment during the epidemic period, and no aggravation occurred of the 92 patients, 35 were in the high risk area, 10 were in the medium risk area, and 47 were in the low risk area. Exclude OVCF for NCP Patients were treated according to the conventional diagnosis and treatment principles. Suspected and confirmed cases are transferred to designated surgical hospitals for treatment. All patients were followed up 3 months, 6 months and 12 months after treatment. There was no death rate, high satisfaction of pre-hospital first aid, high diagnostic accuracy, and good curative effect. None of the rescue personnel had any infection rate, and no hospital infection transmission and nosocomial cross infection occurred. Conclusion: It is the first step to safely treat patients and prevent cross infection to establish a perfect synchronous strategy of pre-hospital first aid and infection prevention and control.

Effect of vertebroplasty combined with pedicle internal fixation on senile osteoporotic vertebral compression fracture

Objective:To investigate the effect of vertebroplasty combined with pedicle screw fixation in the treatment of senile osteoporotic vertebral compression fractures.Methods:Eighty-one patients with senile osteoporotic vertebral compression fractures were enrolled in our hospital from January 2015 to January 2019.They were randomly divided into a single group(40 cases)and a combined group(41 cases).),a single group was treated with pedicle screw internal fixation,and the combined group was treated with vertebroplasty.The recovery,pain and dysfunction index of the injured vertebrae before and after operation were compared between the two groups.The serum neurological function related indexes before and after operation were compared and the incidence of postoperative adverse events were recorded.Results:There was no significant difference in the recovery of the injured vertebrae between the two groups(P>0.05).The compression ratio,spinal stenosis rate and Cobb angle of the combined group were significantly lower than the single group(P<0.05).On the 3rd postoperative day,there were no significant differences between the two groups in Visual Analogue Scale/Score(VAS)and Oswestry Dability Index(ODI)scores(P>0.05).The VAS and ODI scores of the group were significantly lower than those of the single group(P<0.05).On the 3rd day after surgery,the neuron-specific enolase(NSE)and brain derived neurotrophic factor(brain-derived neurotrophic factor)were used.The levels of BDNF,S100βand Nerve growth factor(NGF)were not significantly different(P>0.05).At 3 months after operation,the level of BDNF in the combined group was significantly higher than that in the single group.The levels of NSE,S100βand NGF were significantly lower than that of the single group.The group(P<0.05);the incidence of adverse events in the combined group was significantly lower than that in the single group(P<0.05).Conclusions:Vertebroplasty combined with pedicle screw fixation for the treatment of senile osteoporotic vertebral compression fracture can effectively improve the recovery of postoperative vertebral body structure,postoperative pain and dysfunction in Jianing patients,improve postoperative neurological function To reduce the incidence of adverse events,with clinical promotion significance.

Incidental vertebral compression fractures in imaging studies:Lessons not learned by radiologists

AIM:To assess radiologists reporting rates of incidental vertebral compression fractures in imaging studies. METHODS:We performed a review of the current literature on the prevalence and reporting rates of incidental vertebral compression fractures in radiologic examinations. RESULTS:The bibliographic search revealed 12 studies:7 studies using conventional radiology and 5 using multidetector computed tomography(MDCT).The lossof height cut-off to define a vertebral fracture varied from 15%to 25%.Fracture prevalence was high (mean 21.1%;range 9.5%-35%)in both radiographic and MDCT studies(mean 21.6%and 20.2%,respectively).Reporting rates were low with a mean value of 27.4%(range 0%-66.3%)and were significantly lower in MDCT than in radiographic studies(mean 8.1%vs 41.1%).Notably,recent studies showed lower reporting rates than older studies. CONCLUSION:Many scientific studies have confirmed a high prevalence of vertebral compression fractures as incidental findings on imaging studies.However,the underreporting of these fractures,as determined in our study,may negatively affect patient care.

Comment on “Outcomes of different minimally invasive surgical treatments for vertebral compression fractures: An observational study”

Recently we read the article entitled“Outcomes of different minimally invasive surgical treatments for vertebral compression fractures:An observational study”.This was an observational study that reviewed the safety and efficacy of different cement augmentation modalities for vertebral compression fractures under osteoporotic condition.Overall,this is a valuable study that can provide a reference for clinical practice.On the other hand,we also noticed some points in the article and are willing to share our views.Further studies with a higher level of evidence can add more knowledge regarding relevant concerns.

Effect of Osteoporotic Vertebral Compression Fracture on Adjacent Intervertebral Disc Degeneration

Objective:The influence of vertebral compression fracture on the degeneration of adjacent disc was analyzed.Methods:88 patients with osteoporotic vertebral compression fractures admitted to the orthopedic pain department from July 2014 to July 2019 were selected as the research objects.According to the previous MRI and the improved MRI results of admission,the patients were converted into old fractures after conservative treatment.They were followed up in 3,6 and 12 months after discharge,and the VAS score at each time point(visual acuity score)was calculated We collected and analyzed the classifcation of intervertebral disc degeneration and MRI index.Results:The follow-up rate was 659%(58/88);There were 42 cases(72.4%)of degenerative disc adjacent to the diseased vertebra,and 16 cases(27.5%)of adjacent intervertebral disc did not degenerate;VAS scores were 1ower at 14 days,3 months,6 months and 12 months after admission;The number of grade 1 of disc degeneration was lower in 6 months and 12 months than that in admission(P<0.05),and the number of grade 2,3 and 4 was significantly higher than that in the follow-up in December(P<0.05).The difference between 6 and 12 months was not statistically significant(P>0.05);MRI index at 6 and 12 months follow-up was lower than that at admission(P<0.05).Conclusion:Through the research and analysis,we found that osteoporotic vertebral compression fracture will have a corresponding impact on the adjacent intervertebral disc,which can make the adjacent intervertebral disc degenerate.

Comparative Analysis and Exploration of Clinical Value of Kyphoplasty and Conservative Treatment for Osteoporotic Vertebral Compression Fractures

Objective:To explore the clinical value of kyphoplasty and conservative treatment for osteoporotic vertebral compression fractures.Methods:40 patients with Osteoporotic vertebral compression fracture from May 2019 to November 2021 were selected.The control group was treated with conservative treatment and the experimental group was treated with kyphoplasty.Results:Compared with the control group,the experimental group had higher total effective rate(95.00%),better recovery of Cobb Angle and vertebral height,and higher quality of life score.The data was more meaningful(P<0.05).Conclusion:For patients with osteoporotic vertebral compression fractures,the application of kyphoplasty can improve the treatment effect,accelerate the recovery of vertebral body function and enhance the quality of life,which is worthy of popularization.

Outcome analysis of surgical interventions for osteoporotic vertebral compression fractures

Biomechanical Study of Vertebral Compression Fracture Using Finite Element Analysis

This research aimed to mechanically analyze vertebral stress concentration in one healthy subject and one subject with osteoporotic first lumbar (L1) vertebral compression fracture by using finite element analysis (FEA). We constructed three-dimensional image-based finite element (FE) models (Th12L2) by using computed tomographic (CT) digital imaging and communications in medicine (DICOM) for each patient and then conducted exercise stress simulations on the spine models. The loadings on the 12th thoracic vertebra (Th12) due to compression, flexion, extension, lateral bending, and axial rotation were examined within the virtual space for both spine models. The healthy and vertebral compression fracture models were then compared based on the application of equivalent vertebral stress. The comparison showed that vertebral stress concentration increased with all stresses in the vertebral compression fracture models. In particular, compression and axial rotation caused remarkable increases in stress concentration in the vertebral compression fracture models. These results suggest that secondary vertebral compression fractures are caused not only by bone fragility but possibly also by the increase in vertebral stress concentration around the site of the initial
