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.

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.

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.

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.

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.

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.

Minimally Invasive Open Reduction and Internal Fixation for Osteoporotic Vertebral Compression Fractures: Technical Report and Mid-Term Outcomes

Background: Traditional open instrumentation may cause surgical complications due to fragile bones and induce medical comorbidities in senile patients. Vertebroplasty and kyphoplasty are palliative augmentation procedures that have been associated with increased risks of cement leakage, adjacent fractures and non-union. Objective: The aim of this study was to describe a novel approach for the union of osteoporotic vertebral compression fractures with minimally invasive open reduction and internal fixation. Patients and Methods: Seven consecutive patients with intractable back pain without neurological deficits due to osteoporotic vertebral compression fractures were treated using minimally invasive fixation with intra-vertebral expandable pillars and artificial bone substitute. The clinical symptoms and image findings were recorded. Results: All of the patients reported relief of back pain, and the height of the vertebral bodies was well restored. X-ray findings obtained 2 to 4 years after the procedures showed fracture healing and favorable formation of the callus confirmed in the anterior longitudinal ligament. Conclusion: This mini-open procedure with intravertebral devices is an effective and reliable technique for osteoporotic vertebral compression fractures and may avoid complications related to traditional open spinal instrumentation procedures and augmentation with bone cement.

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.

Meta-analysis of percutaneous kyphoplasty for elderly osteoporotic vertebral compression fractures

Objective:To evaluate the clinical efficacy of percutaneous kyphoplasty(PKP)in the treatment of osteoporotic vertebral compression fractures(OVCF)in the elderly by meta-analysis,and to provide a basis for clinical application.Methods:CNKI,Wanfang,Weipu,CBM,PubMed,the Cochrane Library and EMbase were retrieved by computer from the date of establishment to January 2019.The literature on randomized controlled trials of PKP and conservative treatment of OVCF was collected and diagnosed as thoracolumbar vertebral compression fracture by X-ray,CT,and MRI.Osteoporosis of thoracolumbar vertebrae(T<2.5)was determined by bone mineral density measurements.Age(>50 years old)and course of the disease(<3 months).Postoperative outcome indicators included at least one of the following indicators:visual analogue scale.VAS and Oswestry Dysfunction Index(ODI),changes of Cobb angle of diseased vertebrae and height of the anterior edge of diseased vertebrae.The quality of the included literature was evaluated by referring to the evaluation criteria for randomized controlled trials provided in the Cochrane Systematic Evaluation Manual.Results:Six randomized controlled trials studies were included,all of which were Chinese literature.Five of them had 4 or more points in methodological quality evaluation and one had 3 points in methodology quality evaluation.There were 525 patients in the two groups,267 in the PKP group and 258 in the conservative treatment group.Meta-analysis showed that the pain visual analogue score in the PKP group was significantly higher than that in the conservative treatment group[MD=2.10,95%CI(-2.25,-1.95),P<0.00001].There were significant differences between the PKP group and the conservative treatment(CT)group[MD=8.90,95%CI(-9.86,-7.94),P<0.00001]in the changes of the Cobb angle of the diseased vertebrae after treatment.There were significant differences in the ODI and the height of the anterior edge of the diseased vertebrae(P<0.05).Conclusion:PKP treatment of OVCF can effectively reduce pain visual analogue score,improve dysfunction index(ODI)and improve the quality of life of patients.It can also effectively restore the height of vertebral loss,correct the Cobb angle of the diseased vertebrae,and reduce the risk of recurrent fracture of the adjacent vertebral body and serious complications.

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

The Clinical Effect of Zoledronic Acid Combined with Teriparatide in Perverting Recurrent Fracture of Osteoporotic Vertebral Compressive Fractures in the Elderly after Percutaneous Kyphoplasty

Background: Zoledronic acid and teriparatide have been proved to be effective in improving bone metabolism and preventing fractures, but there is no clear clinical report on the efficacy of their combined application. Purpose: To discuss the clinical effect of zoledronic acid combined with teriparatide in perverting recurrent fracture of osteoporotic vertebral compressive fractures (OVCF) in the elderly after percutaneous kyphoplasty (PKP). Method: A randomized clinical trial was conducted at the First Affiliated Hospital of Hebei North University in China from September 2018 and September 2019. A total of 60 patients with OVCF were enrolled in the study (zoledronic acid: 20 cases;teriparatide: 20 cases;zoledronic acid + teriparatide: 20 cases). Observe and compare the changes of bone mineral density (BMD), pro-collagen type I N-terminal propeptide (PINP) and cross-linked C-terminal telopeptide of type I collagen (β-CTX) before surgery, 6 months and 1 year after surgery. At the same time, secondary fracture events and adverse reaction events were recorded during the follow-up period. Results: After normalized treatment, the bone metabolism indexes of PINP and β-CTX were improved and BMD was increased in three groups. Adverse Reactions: There was no statistical significance in the incidence of fever, gastrointestinal reactions and myalgia among the three groups (P > 0.05). The incidence of recurrent fractures in group A was higher than that in group C (P < 0.05), but there was no significant difference between group B and group C (P > 0.05). Conclusion: Zoledronic acid combined with teriparatide is superior to Zoledronic acid in preventing the risk of recurrent fracture after PKP for old patients with OVCF, but it has no significant advantage over teriparatide.

Pedicle Screw Fixation with Kyphoplasty Decreases the Fracture Risk of the Treated and Adjacent Non-treated Vertebral Bodies:a Finite Element Analysis

Adjacent vertebral fractures are common in patients with osteoporotic vertebral compression fractures（OVCFs） after kyphoplasty.This finite element study was to examine whether short segment pedicle screw fixation（PSF） with kyphoplasty may decrease the fracture risk of the treated and adjacent non-treated vertebrae after kyphoplasty for OVCFs.By simulating cement augmentation with or without short segment pedicle screw fixation（PSF）,two tridimensional,anatomically detailed finite element models of the T10–L2 functional spinal junction were developed.The insertion of pedicle screws into the intact vertebra apparently decreased the stress distribution of the treated vertebra in vertical compression and other load situations.The stress distribution in the bone structures of the intact vertebra adjacent to the intact-screwed vertebra was much less than that in the one adjacent to the treated vertebra.The insertion of pedicle screws into the intact vertebra greatly decreased the maximum displacement of the cortical bones and cancellous bones of the vertebrae.Our results indicated that short segment PSF with kyphoplasty may decrease the fracture risk of the treated and adjacent non-treated vertebrae in the management of OVCFs.

Adjacent Level Vertebral Fractures in Patients Operated with Percutaneous Vertebroplasty

Percutaneous vertebroplasty is a minimally invasive procedure that involves filling of a fractured vertebral body with bone cement to relieve pain and to restore the vertebral height. It is a safe and effective treatment and is widely used for treating Osteoporotic Vertebral Compression Fracture. Despite of its beneficial advantages over primary conservative managements, adjacent level vertebral compression fracture remains the challenge for surgeons. Adjacent level vertebral compression fracture following percutaneous vertebroplasty using PMMA cement has been reported as a complication. Numerous risk factors have been reported for the occurrence of new adjacent VCFs after PVP. The multiple level osteoporotic vertebral compression fractures and the increasing age of the patients are directly proportional to the risk of developing new symptomatic adjacent vertebral compression fracture after PVP. Moreover, low BMD and cement leakage are other factors that directly affect the incidence of new symptomatic adjacent vertebral fractures. The aim of this review is to evaluate the adjacent level vertebral compression fracture following percutaneous vertebroplasty on the basis of radiographs, Kaplan-Meier Estimation index and also the factors that lead to adjacent level vertebral compression fractures.

老年女性骨质疏松性骨折相邻椎体再骨折的影响因素及列线图预测模型构建

背景:有关老年女性骨质疏松性椎体压缩性骨折患者相邻椎体再骨折的研究较多,但其相关危险因素仍在争论中,如何将其风险直观地呈现以便于临床应用的研究较少。目的:分析影响老年女性骨质疏松性椎体压缩性骨折患者相邻椎体再骨折的危险因素并构建列线图(Nomogram)预测模型。方法:选择2018年1月至2022年11月赣州市人民医院收治的268例老年女性骨质疏松性椎体压缩性骨折患者,经皮穿刺椎体成形术后3个月根据是否发生相邻椎体再骨折分为研究组(发生相邻椎体再骨折,n=31)和对照组(未发生相邻椎体再骨折,n=237)。比较两组患者一般临床资料,采用多因素Logistic回归分析影响老年女性骨质疏松性椎体压缩性骨折患者相邻椎体再骨折的独立风险因素,利用R软件“rms”包构建Nomogram预测模型。结果与结论:①两组患者的年龄、绝经年龄、体质量指数、骨折病史、术前骨折椎体数、骨水泥渗漏、骨密度、术后后凸畸形角度、术前Oswestry功能障碍指数比较差异均有显著性意义(P<0.05);②多因素Logistic回归分析结果显示,年龄(>69岁)、绝经年龄(≤51岁)、体质量指数(>24.7 kg/m^(2))、骨折病史(有)、术前骨折椎体数(≥2)、术后后凸畸形角度(>13°)是影响老年女性骨质疏松性椎体压缩性骨折患者相邻椎体再骨折的独立危险因素(P<0.05);③Nomogram预测模型决策曲线结果显示,当风险阈值>0.09时,此预测模型可以提供显著额外的临床净收益;④结果表明,年龄较大、绝经年龄较低、体质量指数较高、有骨折病史、术前骨折椎体数较多、术后后凸畸形角度较大是老年女性骨质疏松性椎体压缩性骨折患者相邻椎体再骨折的独立影响因素,基于此构建的Nomogram预测模型可为此类患者相邻椎体再骨折的防治提供重要的策略指导。

目的研究骨化三醇用于老年骨质疏松性椎体压缩性骨折(OVCF)病人经皮椎体后凸成形术(PKP)后治疗对骨折愈合和血清骨碱性磷酸酶(BALP)、Ⅰ型前胶原N-端前肽(PINP)、胶原羧基端肽β特殊序列(β-CTX)表达水平的影响。方法纳入2019—2020年我院接受PKP手术的106例OVCF病人为研究对象,并采用随机数表法均分为观察组和对照组,每组53例。对照组PKP术后给予钙剂+阿仑膦酸钠片进行治疗,观察组在此基础上加用骨化三醇进行治疗,2组疗程均为6个月,比较2组临床疗效、Cobb角、Oswestry功能障碍指数(ODI)、骨密度和骨代谢指标的差异。结果2组治疗6个月有效率分别为90.57%和83.02%,差异无统计学意义(P>0.05),优良率分别为73.58%和52.83%,差异有统计学意义(P<0.05)。2组治疗1、3、6个月时Cobb角和ODI均明显低于治疗前(P<0.05),且观察组治疗6个月时ODI低于对照组,差异有统计学意义(P<0.05)。2组治疗3、6个月时骨密度均明显高于治疗前(P<0.05),且观察组治疗6个月时骨密度高于对照组,差异有统计学意义(P<0.05)。与治疗前相比,2组治疗1、3、6个月时BALP和PINP水平明显升高(P<0.05),β-CTX水平均明显降低(P<0.05),且观察组治疗1、3、6个月时BALP和PINP水平均高于对照组,差异有统计学意义(P<0.05)。结论OVCF病人PKP术后应用骨化三醇进行治疗具有良好效果,有利于改善骨代谢并增加骨密度,对促进骨折愈合、改善脊柱功能和提升日常生活能力具有积极作用。
