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.

Percutaneous vertebroplasty in the treatment of malignant vertebral compression fractures with epidural involvement

Purpose: To evaluate the safety and the clinical efficacy of percutaneous vertebroplasty(PVP) in treating malignant spinal tumors and malignant vertebral compression fractures with epidural involvement. Materials and methods: 43 patients with spinal metastatic tumors and malignant vertebral compression fractures with epidural involvement were treated using PVP. American Spinal Injury Association(ASIA) impairment scale results at presentation were used to divide patients into 2 groups. Patients in group A had no symptoms of neurological compression(n = 25); and patients in group B had symptoms of neurological compression(n = 28). A 13 G bone puncture needle was placed across the pedicle of the fractured vertebra, and polymethyl methacrylate(PMMA) was injected into the fractured vertebral body under fluoroscopic control. Patients were seen in follow-up at 1, 3, and 6 months after the procedure and every six months thereafter. Results: PVP was technically successful and well-tolerated in all patients. Clinical assessment at the final follow-up found complete pain relief(n = 19) or good pain relief(n = 14) in 33 patients(62.3%, 95% CI: 49%, 76%). ASIA impairment scale assessment at the final follow-up demonstrated symptoms of neurologic compression in 31 patients and no symptoms of neurologic compression in 22 patients. Symptoms of neurologic compression were found in five group A patients and eight group B patients. Conclusions: PVP was a safe and moderately effective procedure in the treatment of malignant vertebral compression fractures with epidural involvement.

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.

Injectable bioactive polymethyl methacrylate-hydrogel hybrid bone cement loaded with BMP-2 to improve osteogenesis for percutaneous vertebroplasty and kyphoplasty

Poly methyl methacrylate(PMMA)bone cement is used in augmenting and stabilizing fractured vertebral bodies through percutaneous vertebroplasty(PVP)and percutaneous kyphoplasty(PKP).However,applications of PMMA bone cement are limited by the high elasticity modulus of PMMA,its low biodegradability,and its limited ability to regenerate bone.To improve PMMA bio activity and biodegradability and to modify its elasticity modulus,we mixed PMMA bone cement with oxidized hyaluronic acid and carboxymethyl chitosan in situ cross-linking hydrogel loaded with bone morphogenetic protein-2(BMP-2)to achieve novel hybrid cement.These fabric ated PMMA-hydrogel hybrid cements exhibited lower setting temperatures,a lower elasticity modulus,and better biodegradability and biocompatibility than that of pure PMMA cement,while retaining acceptable setting times,mechanical strength,and inj ectability.In addition,we detected release of BMP-2 from the PMMA-hydrogel hybrid cements,significantly enhancing in vitro osteogenesis of bone marrow mesenchymal stem cells by up-regulating the gene expression of Runx2,Coll,and OPN.Use of PMMA-hydrogel hybrid cements loaded with BMP-2 on rabbit femoral condyle bone-defect models revealed their biodegradability and enhanced bone formation.Our study demonstrated the favorable mechanical properties,biocompatibility,and biodegradability of fabricated PMMA-hydrogel hybrid cements loaded with BMP-2,as well as their ability to improve osteogenesis,making them a promising material for use in PKP and PVP.

Percutaneous vertebroplasty versus percutaneous kyphoplasty for the treatment of delayed post-traumatic vertebral body collapse(Kümmell’s disease) in Chinese patients: a systematic review and meta-analysis

Objective: To compare the clinical efficacy between percutaneous vertebroplasty(PVP) and percutaneous kyphoplasty(PKP) in the treatment of Kümmell's disease in Chinese patients.Methods: The studies using randomized controlled trials to compare clinical efficacy between PVP and PKP in the treatment of Kümmell's disease in Chinese patients were retrieved from Embase, Pubmed, Central, Cinahl, PQDT, CNKI, CQVIP, Wanfang Data, and CBM(from September 2008 to September 2018). Keywords for both Chinese and English search were: percutaneous vertebroplasty, PVP, percutaneous kyphoplasty, PKP, and Kümmell's disease. A total of 132 articles were retrieved based on the search strategy through online database searching and manual searching. Finally, one foreign report and seven Chinese reports were included. After extracting the data, statistical software Review Manager 5.3 was used for data analysis.Results: Through comparison, Cobb angle(95% CI [0.54, 4.42), P = 0.01] and Oswestry Dysfunction Index(ODI)(95% CI [0.21, 2.15], P= 0.02) of PKP group was smaller than that of PVP group. Postoperative anterior vertebral body height of the PKP group was better than PVP group(95% CI [-1.27,-0.66], P < 0.001]. However, the PVP group had shorter operation time than PKP group(95% CI [-13.48,-7.43), P = 0.001]. In the other outcome measures, including Visual Analogue Scale(VAS) score(95% CI [-0.04, 0.27), P = 0.15), cement volume(95% CI [-0.82, 0.32], P = 0.39) and cement leakage(95% CI [0.90, 2.76], P = 0.11), there was no significant differences between the two procedures.Conclusions: At this stage, there is sufficient evidence to support that PKP is better than PVP in the treatment of Kümmell's disease in Chinese patients. Although PVP surgery requires much less operation time, PKP has better postoperative radiological results and lower ODI. Moreover, both of them had similar clinical results(e.g., analgesic effects, cement dosage, and leakage rate). Further evidence is dependent on the emergence of randomized controlled trials with higher quality and larger sample sizes in the future.

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.

Total spinal anesthesia caused by lidocaine during unilateral percutaneous vertebroplasty performed under local anesthesia:A case report

BACKGROUND Intradural anesthesia caused by anesthetic drug leakage during percutaneous vertebroplasty(PVP)has rarely been reported.We here report a 71-year-old woman who suffered this rare and life-threatening complication during PVP.CASE SUMMARY A 71-year-old woman,who suffered from 2 wk of severe back pain with a visual analog score of 8,came to our outpatient clinic.She was later diagnosed with a newly compressed L1 fracture and was then admitted in our department.PVP was initially attempted again under local anesthesia.However,serendipitous intradural anesthesia leading to total spinal anesthesia happened.Fortunately,after successful resuscitation of the patient,PVP was safely and smoothly performed.Great pain relief was achieved postoperatively,and she was safely discharged on postoperative day 4.The patient recovered normally at 3-mo follow-up.CONCLUSION Total spinal anesthesia secondary to PVP by anesthetic drug leakage rarely occurs.In cases of inadvertent wrong puncture leading to drug leakage when performing it under local anesthesia,surgeons should be highly vigilant during the whole procedure.Electrocardiogram monitoring,oxygen inhalation,intravenous cannula set prior to surgery,regular checking of motor activity and a meticulous imaging monitoring with slower pushing of anesthetic drugs,etc.should be highly recommended.

Traditional Chinese medicine manipulative reduction combined with percutaneous vertebroplasty for treating type Ⅲ Kummell's disease: A case report

BACKGROUND A patient with type Ⅲ Kummell’s disease had a ruptured posterior cortex of the fractured vertebral body, which caused spinal cord compression. An open surgery was considered the best choice of operation. However, the patient and her family refused open surgery and instead demanded a minimally invasive surgical treatment such as percutaneous vertebroplasty(PVP). After preoperative discussion, we finally adopted the novel therapy of traditional Chinese medicine manipulative reduction(TCMMR) combined with PVP.CASE SUMMARY A patient with type Ⅲ Kummell’s disease exhibiting bone block-induced spinal cord compression was admitted to our hospital. She suffered from a variety of medical disorders but refused open surgery, and instead asked for PVP surgery. TCMMR, in parallel with PVP, was used to restore the height of the compressed vertebral body and reduce the symptoms of spinal cord compression by the bone block in order to strengthen the vertebral body and prevent further collapse. The surgery was very successful. The height of the compressed vertebra was restored, and the symptom of spinal cord compression by bone block was reduced successfully via TCMMR. The fractured vertebra was solidified by the PVP. The pain visual analog score declined from preoperative 7 scores to postoperative 2 scores, and the Frankel spinal cord scale increased from preoperative D degree to postoperative E degree.CONCLUSION The new method has advantages in treating patients with type Ⅲ Kummell’s disease who cannot be treated with open surgery.

Percutaneous vertebroplasty: technical considerations

Percutaneous vertebroplasty (PVP) is a relative new interventional technique, which is widely used in treatment of vertebral collapse caused by vertebral neoplasms and osteoporotic compression fractures. The general technical considerations of PVP techniques are discussed based on authors’ experience obtained over 400 patients in the past years in this article, including preparation of PMMA, instrument of PVP, guidance and puncture approaches, and technique of the procedure, etc. The conclusion is that PVP is a safe procedure if the physicians handle it properly.

Results: Follow-up results among 15 pa tients were studied, other two patients lost contact. The follow-up period was from three to seven months. No patient had relapse of compression fracture. Leak age of the cement outside the vertebral body was seen in four bodies. All patien ts had a complete relief after Percutaneous vertebroplasty(PVP). Conclus ion: PVP is an efficient minimally invasive technique to treat osteoporo tic vertebral body compression fractures.

Clnical Study of the Treatment of Patients with a Metastatic Spinal Tumor by Percutaneous Vertebroplasty under the Guidance of DSA

OBJECTIVE To explore the clinical effect in patients with metastatic spinal tumors treated by percutaneous vertebroplasty （PVP） under the guidance of digital subtraction angiography （DSA）. METHODS A total of 110 cases with a metastatic spinal tumor were di- vided into 55 cases in the treatment group （group A ） and 55 cases in the control group （group B ）. The general clinical data were statistically analyzed before treatment with the parameters showing no differences. Group A was treated by PVP and chemotherapy as well. Group B was treated by the regular chemotherapy and regular radiation therapy. The same chemotherapy program was used for the same type of disease. All cases were provided with a follow-up survey for 12 months. During the follow-up survey, changes in the quality of life, in evaluation of bone pain and in vertebral column stability as well as adverse reactions were observed. RESULTS The statistics showed a significant difference between the 2 groups, specifically changes in the quality of life and evaluation of bone pain （P〈0.05, t1=2.74, t2=9.02）. During the follow-up survey, 5 cases in group A died of other organ complilcations, the death rate being 9.1% （5 out of 55）, but all survived more than 3 months following PVP. The vertebral columns of the survivors were kept stable, with no pathological fractures occurring in the vertebral bodies filled with bone cement, there were no obvious adverse reactions, and no paraplegia occurred. Thirteen cases died in group B with a death rate of 23.6% （13 out of 55）. Pathological compression fractures in the vertebral bodies occurred in 30 cases, and 12 cases of complicated paraplegia were noted. The incident rate of paraplegia was 21.8% （12 out of 55）. CONCLUSION PVP is a simple operation causing only small wounds and few complications. It can effectively alleviate pain of metastatic spinal tumors in patients, improve quality of life and reduce the incidence rate of paraplegia.

Percutaneous osteoplasty for extraspinal metastases

As an extension of percutaneous vertebroplasty(PVP), percutaneous osteoplasty(POP) refers broadly to percutaneous bone cement injected into various parts of the body and narrowly to cement injected into extraspinal bone lesions. POP mainly includes such surgeries as percutaneous sacroplasty, percutaneous acetabuloplasty, percutaneous femoral osteoplasty, and percutaneous iliac osteoplasty(Figure 1). Currently, POP is a positive and an effective treatment for extraspinal bone lesions in that it can rapidly relieve pain, effectively prevent pathological fractures, and partially inactivate tumors, with few complications. The aim of this review is to detail the POP techniques and report their safety and efficacy in the treatment of extraspinal metastases.

PVP治疗骨质疏松性椎体压缩骨折术后24 h疗效分析

为了探讨影响经皮椎体成形术(percutaneous vertebroplasty,PVP)治疗骨质疏松性椎体压缩骨折(osteoporotic vertebral compression fractures,OVCF)术后24 h手术效果的影响因素,通过回顾性分析2015年1月—2022年1月邯郸市中心医院骨五科行PVP治疗的351名OVCF患者,根据Macnab量表将术后24 h手术效果分类,将患者分为满意组(A)和不满意组(B),分析患者骨折时间、术前VAS(visual analogue scale)评分、抑郁症病史等相关因素,将有统计学意义的变量进行二元Logistic回归分析。结果表明:两组比较,患者骨折时间、术前VAS评分、有无抑郁症病史均存在显著性差异(P<0.05)。Logistic回归分析显示骨折时间长、术前VAS评分低、有抑郁症病史为PVP术后24 h患者不满意的独立危险因素。可见PVP术后手术效果与患者骨折时间、术前VAS评分、有无抑郁症病史有关;骨折时间≤3周、术前VAS评分≥7分、无抑郁症的患者手术效果好,患者满意度更高。
