RESUMO

ABSTRACT: To identify the risk factors of the secondary fractures for osteoporotic vertebral compression fractures (OVCFs) after percutaneous vertebroplasty (PVP).We conducted a search of relevant articles using Cochrane Library, PubMed, Medline, Science Direct, Embase, the Web of Science and other databases. The time range we retrieved from establishment of the electronic database to November 2017. Gray studies were found in the references of included literature reports. STATA version 11.0 (Stata Corporation, College Station, Texas) was used to analyze the pooled data.Fourteen studies involving 1910 patients, 395 of whom had fracture secondary to the surgery were included in this meta-analysis. The result of meta-analyses showed the risk factors of the secondary fractures for OVCFs after PVP was related to bone mineral density (BMD) [95%CI (-0.650, -0.164), SMD=-0.407, P=.001], cement leakage ((RR=0.596, 95%CI (0.444,0.798), P = .001)), and kyphosis after primary operation ((SMD=0.741, 95%CI (0.449,1.032), P = .000)), but not to gender, age, body mass index, cement volume, thoracolumbar spine, and cement injection approaches.Bone mineral density, cement leakage, and kyphosis after primary operation are the risk factors closely correlative to the secondary fracture after PVP. There have not been enough evidences to support the association between the secondary fracture and gender, age, body mass index, cement volume, thoracolumbar spine, and cement injection approaches.

RESUMO

Objective: To investigate the risk factors of adjacent fractures after percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fracture (OVCF). Methods: A total of 2 216 patients who received PVP due to symptomatic OVCF between January 2014 and January 2017 and met the selection criteria were selected as study subjects. The clinical data was collected, including gender, age, height, body mass, history of smoking and drinking, whether the combination of hypertension, diabetes, coronary arteriosclerosis, chronic obstructive pulmonary disease (COPD), bone mineral density, the number of fractured vertebrae, the amount of cement injected into single vertebra, the cement leakage, and whether regular exercise after operation, whether regular anti-osteoporosis treatment after operation. Firstly, single factor analysis was performed on the observed indicators to preliminarily screen the influencing factors of adjacent fractures after PVP. Then, logistic regression analysis was carried out for relevant indicators with statistical significance to screen risk factors. Results: All patients were followed up 12-24 months, with an average of 15.8 months. Among them, 227 patients (10.24%) had adjacent fractures. The univariate analysis showed that there were significant differences between the fracture group and non-fracture group in age, gender, preoperative bone density, history of smoking and drinking, COPD, the number of fractured vertebrae and the amount of bone cement injected into the single vertebra, as well as regular exercise after operation, regular anti-osteoporosis treatment after operation ( P<0.05). Further multivariate logistic regression analysis showed that the elderly and female, history of smoking, irregular exercise after operation, irregular anti-osteoporosis treatment after operation, low preoperative bone density, large number of fractured vertebrae, and small amount of bone cement injected into the single vertebra were risk factors for adjacent fractures after PVP in OVCF patients ( P<0.05). Conclusion: The risk of adjacent fractures after PVP increases in elderly, female patients with low preoperative bone mineral density, large number of fractured vertebrae, and insufficient bone cement injection. The patients need to quit smoking, regular exercise, and anti-osteoporosis treatment after PVP.

RESUMO

Vertebral compression fractures (VCFs) result from either trauma or a pathologic process that weakens the bone by conditions such as osteoporosis or tumor. The incidence of VCFs has been rising over the last few decades in accordance with the aging population. These fractures can result in severe pain, physical limitation and disability, as well as increased morbidity and mortality. Patients with VCFs are optimally treated by accurate and early diagnosis and treatment. An effective method to treat these fractures is percutaneous vertebral augmentation, which is a set of minimally invasive procedures that stabilizes osseous fractures, provides immediate pain relief, and improves quality of life. Vertebral augmentation procedures include vertebroplasty, kyphoplasty, and vertebral augmentation with implants. Each of these techniques is described in general terms in this article. The ideal candidate for vertebral augmentation is a patient with a symptomatic fracture seen on cross-sectional imaging in which nonsurgical management has failed and has positive signs on physical examination with no absolute contraindication. This procedure should be done with the appropriate equipment and personnel in a facility designed for this purpose. After the procedure, the patient should undergo the appropriate follow-up to ensure optimal recovery. Additionally, it is essential that the patient receives appropriate therapy for the underlying disorder that predisposed them to the vertebral fracture.

RESUMO

Objective: To analyze the safety and efficacy of percutaneous vertebroplasty combined with interstitial implantation (125)I of seeds (PVPI) in the treatment of thoracic vertebroplasty with posterior vertebra defect. Methods: A retrospective analysis of the clinical data of 64 patients with thoracic spine metastases admitted to Yunnan Cancer Hospital from November 2017 to May 2019 was conducted, including 32 patients with posterior vertebra defect (experimental group) and 32 cases without (control group). Forty-two vertebral bodies of 32 patients in the experimental group were treated with improved PVPI surgery, which performed with the secondary sealing method and inclined puncture needle injection bone cement rotary filling technology, to reduce leakage. The 54 vertebral bodies of 32 patients in control group underwent PVPI. The two groups of patients were followed up on the second day, one month, three months and six months after the operation, and the short-term efficacy, long-term efficacy and safety indicators of the two groups were compared. Results: All 64 patients successfully completed the surgical treatment. The visual analogue scores and Karnofsky scores of the experimental group and the control group were improved to varying degrees on the second day, 1 month, 3 months and 6 months after the operation. There was no statistically significant difference between the two groups (P>0.05). The amount of bone cement in the experimental group and control group was (2.36±0.20) ml and (2.39±0.17) ml, and the difference was not statistically significant (P=0.482). The amount of (125)I seed implantation was (30.63±0.91) and (32.56±0.68), respectively, the difference was not statistically significant (P=0.925). The partial response rates of the study group and the control group were 81.3% and 87.5%, the stable disease rates were 12.5% and 9.4%, the differences were not statistically significant (P>0.05). The median overall survival (mOS) of the study group was 13 months, and the median progression-free survival (mPFS) was 8 months. The mOS of the control group was 14 months, and the mPFS was 8 months. The differences were not statistically significant (P>0.05). In the experimental group, 6 (14.3%) vertebral bodies had cement leakage, of which 2 (4.8%) were cement leakage at posterior vertebra, 4 (9.5%) were paravertebral cement leakage. Seven (13.0%) paravertebral cement leakage occurred in the control group. There was no significant difference in bone cement leakage between the two groups (P=0.097). Bone cement leakage in both groups did not cause serious complications such as spinal cord injury and paraplegia. Conclusion: The application of PVPI in the treatment of thoracic metastatic tumor patients with posterior vertebra defect can acquire better clinical efficacy and safety through conduction of the improved intraoperative technology and paying more attention to the control of bone cement distribution and other issues.

RESUMO

HISTORY AND CLINICAL FINDINGS: Emergency admission of a 66-years-old man with right-sided and partly breath-dependent chest pain in the interdisciplinary emergency room. The complaints existed for several days and had a progressive character. Purulent expectoration and fever were negated. There was a history of COPD with occasional pulmonary exacerbations. Several weeks before the current event, community-acquired pneumonia had been treated with antibiotics. Moreover, the patient reported on multiple spine surgery procedures performed in recent months. INVESTIGATIONS AND DIAGNOSIS: In transthoracic echocardiography (TTE), detection of a foreign body (Palacos) in the right ventricle, which was confirmed to be a toothpick-like structure in the supplementary CT scan of the thorax and the transoesophageal echocardiography (TOE). TREATMENT AND COURSE: Foreign body extraction using right anterior mini thoracotomy. Subsequently, iatrogenic pneumothorax with bilateral nosocomial pneumonia and drainage. After short-term convalescence, renewed admission with bilateral pulmonary infiltrates. Under invasive ventilation, new left-sided pneumothorax was diagnosed, which was supplied with a Bülau drainage. Due to the detection of positive blood cultures, re-conducting of a TOE examination. Now first diagnosis of tricuspid valve endocarditis. Despite successful surgical biologic tricuspid valve replacement with an epicardial pacemaker electrode placement, the patient died approximately three quarters of a year after he became an emergency patient due to dyspnoea. DISCUSSION: The present case shows that a typical clinical symptom, associated with a previously known chronic illness, has to be reminded again and again of other and less common diseases. Even everyday diagnostic and therapeutic procedures are associated with a residual risk of possible complications.

RESUMO

PURPOSE: To assess the safety and efficacy of multilevel thoracolumbar vertebroplasty in the simultaneous treatment of ≥ 6 painful pathologic compression fractures. MATERIALS AND METHODS: Retrospective review was conducted of 50 consecutive patients treated with vertebroplasty for ≥ 6 pathologic compression fractures in a single session for pain palliation at a tertiary single cancer center from 2015 to 2019. Outcomes measured included procedural safety according to Common Terminology Criteria for Adverse Events (CTCAE), change in 4-week postprocedure back pain by numeric rating scale (NRS), comparison of daily opioid medication consumption, and development of skeletal-related events. RESULTS: A total of 397 pathologic compression fractures were treated during 50 sessions (mean, 7.9 per patient ± 1.5). Mean procedure duration was 162 minutes ± 35, mean postoperative hospitalization duration was 1.6 days ± 0.9, and mean follow-up duration was 401 days ± 297. Seven complications were recorded, including 1 case of symptomatic polymethyl methacrylate pulmonary embolism. No major complications (CTCAE grade 4/5) were reported. NRS pain score was significantly decreased (5.0 ± 1.8 vs 1.7 ± 1.4; P < .0001), with a mean score decrease of 3.3 points (66%). Opioid agent use decreased significantly (76 mg/24 h ± 42 vs 45 mg/24 h ± 37; P = .0003), with a mean decrease of 30 mg/24 h (39%). Skeletal-related events occurred in 7 patients (14%). CONCLUSIONS: Multilevel vertebroplasty for ≥ 6 pathologic compression fractures is safe and provides significant palliative benefit when performed simultaneously.

RESUMO

BACKGROUND: Intraspinal cement leakage is a catastrophic complication of percutaneous vertebroplasty (PVP). Percutaneous endoscopic spinal surgery (PESS) for intraspinal cement leakage has rarely been reported. OBJECTIVES: To evaluate the therapeutic effectiveness of PESS for intraspinal cement leakage following PVP. STUDY DESIGN: This was a retrospective study approved by the ethics committee of our institution. SETTING: Department of Orthopedics from an affiliated hospital. METHODS: Twelve patients with neurologic impairments resulting from intraspinal cement leakage after PVP were treated with PESS for spinal decompression from May 2014 to June 2018. Computed tomography and 3-dimensional reconstruction were used to confirm the vertebral level of cement leakage. The surgical index, neurologic function, and clinical results were recorded in this study. RESULTS: The leaked cement of all patients was successfully removed under PESS, and no severe intraoperative complications were reported in our study. The operation time ranged from 43 to 119 minutes (mean, 65.5 minutes). The amount of intraoperative blood loss was 64.25 ± 9.62 mL. The lengths of postoperative hospital stays were 5.25 ± 2.53 days. The follow-up rate was 83.3% (10/12). The follow-up time ranged from 14 to 30 months (mean, 22 months). The Visual Analog Scale scores of foraminal leaks improved from 6.50 ± 0.93 preoperatively to 1.75 ± 0.71 at the last follow-up (P < 0.05). Neurologic function was evaluated by Japanese Orthopaedic Association 29 scores, which improved from 18.75 ± 1.06 to 22.70 ± 1.64 (P < 0.0001). The good and excellent rates were 80% according to the modified Macnab criteria. LIMITATIONS: This study is limited by the volume of patients and the deep learning curve needed for PESS. CONCLUSIONS: PESS, as a minimally invasive technique, can achieve targeted spinal cord decompression and may be a safe and effective alternative approach to conventional procedures for cement leakage after PVP. KEY WORDS: Endoscopes, cement leakage, minimally invasive surgery, percutaneous vertebroplasty.

RESUMO

Percutaneous thermal ablation has proven to be safe and effective in the management of patients with spinal tumors. Such treatment is currently proposed following the decision of a multidisciplinary tumor board to patients with small painful benign tumors such as osteoid osteoma or osteoblastoma, as well as carefully selected patients presenting with spinal metastases. In both scenarios, in order to provide a clinically effective procedure, ablation is often tailored to the specific patients' clinical needs and features of the target tumor. In this review, we present the most common clinical contexts in which spine ablation may be proposed. We scrutinize technical aspects and challenges that may be encountered during the procedure, as well as offering insight on follow-up and expected outcomes.

RESUMO

BACKGROUND: Bone cement augmentation with polymethylmethacrylate is a reliable method for stabilizing osteoporotic compression fractures and improving fixation of pedicle screws. However, cement extrusion into the vertebral venous system can result in pulmonary cement embolism. The goal of this anatomic study was to identify the relationship between the internal/external vertebral plexus and neighboring abdominal caval system. METHODS: Thirty-two lumbar vertebral levels were used in this study. Anterior abdominal dissection was performed to access the lumbar vertebral bodies through the peritoneal cavity, and a 16-gauge needle was placed into the center of each lumbar vertebral body at its anterior aspect. Fluoroscopy was used to confirm if the needle was correctly placed. Next, latex and/or continuous air injections were performed into each lumbar vertebral level (L1-L5). Observations confirmed if the latex or air traveled into the inferior vena cava. In addition, the spinal canal was opened to see if any latex was found to enter inside the vertebral canal in cadavers injected with the latex. RESULTS: Latex or air was found to flow into the inferior vena cava at all the lumbar vertebral levels. The latex/air was not observed in the spinal canal in any specimen. CONCLUSIONS: An exact knowledge of the lumbar vertebral venous anatomy is essential when procedures that could affect the vertebral venous system are involved. Its complexity and anatomic variability necessitate such an understanding to better prevent/understand possible complications associated with polymethylmethacrylate extrusion.

RESUMO

BACKGROUND: Kümmell's disease is a special type of osteoporotic vertebral fracture that causes chronic low back pain and deformity, which seriously affects the living quality of patients. PVP is commonly used to treat osteoporotic vertebral fractures and can quickly relieve low back pain. So, the objective of this study was to analyze the clinical efficacy and experience of bipedicular percutaneous vertebroplasty combined with postural reduction for the treatment of Kümmell's disease. METHODS: A retrospective analysis of patients with Kümmell's disease who underwent bipedicular percutaneous vertebroplasty was conducted from February 2016 to May 2018. Operative time, VAS, bone cement injection volume, cement leakage rate, compression improvement of vertebral front edge and vertebral center, and correction degree of kyphosis were collected and analyzed meticulously. RESULTS: The operative time was 45.33 ± 7.64 min. The volume of bone cement injected was 5.38 ± 1.33 ml. The compression improvement of vertebral front edge was 7.31 ± 1.21%. The compression improvement of vertebral center was 10.34 ± 1.15% and the correction degree of kyphosis was - 2.73 ± 0.31゜. Bone cement leakage occurred in 6 of 39 patients (15.38%), but no clinical symptoms were observed. The VAS scores were significantly lower at 1 day after the surgery, 6 months and at the last follow-up than before the surgery (P = 0.000, respectively). The VAS score was lower at the last follow-up than at 1 day after the surgery (P = 0.001). CONCLUSION: Bipedicular percutaneous vertebroplasty combined with postural reduction could achieve satisfactory analgesic effect in the treatment of Kümmell's disease, and restore the height of the vertebral body and improve kyphosis to some extent.

RESUMO

The study aimed to analyze the radiographic and magnetic resonance imaging (MRI) findings that might predict the risk for adjacent segmental fractures (ASFs) when percutaneous vertebroplasty (PV) is used for the treatment of osteoporotic thoracolumbar fractures (OTFs). A total of 92 OTFs patients who underwent PV between January 2013 and January 2015 were retrospectively reviewed. The visual analog scale (VAS), Oswestry-Disability Index (ODI) and radiolographic measurements were assessed. The VAS and ODI scores improved significantly at the final follow-up (FU) compared with the preoperation scores. Compared with the preoperative values, the fractured body alignment (FBA) significantly improved at the 3-month FU and the final FU, but the adjacent segment alignment (ASA) and thoracolumbar alignment (TLA) did not improve. According to the correlation analysis, the final FU TLA and the final FU ASA were correlated with the preoperative FBA, ASA, and TLA on plain radiography and were highly correlated on MRI. However, the final FU FBA was not correlated with the preoperative FBA, ASA, or TLA on plain radiography or MRI (P > 0.05). The ASFs were correlated with the 3-month FU TLA (r = 0.6044, P = 0.0037) and the final FU TLA (r = 0.5699, P = 0.007) on plain radiography, and the final TLA was more correlated with the preoperative FBA, ASA, and TLA on MRI than on plain radiography. In conclusion, the preoperative ASA and TLA on MRI were risk factors associated with ASFs in OTFs treated with PV.

RESUMO

ABSTRACTPurpose: To measure the projection of the most anterior line of the spinal canal on lateral radiographs of the vertebra (C3-L5) and evaluate the efficacy of the safety line (SL) in preventing intraspinal cement leakage in percutaneous kyphoplasty (PKP) and percutaneous vertebroplasty (PVP). Materials and Methods: Fifteen adult dry-bone spine specimens were analyzed. The projection of the SL was viewed on lateral radiographs. The distance between the SL and the posterior vertebral body line (PVBL) was measured. Two groups of patients were treated by PKP, and cement injection was stopped either before the PBVL (group 1) or before the SL (group 2) under lateral fluoroscopy. The rate of cement leakage was compared between the two groups. Results: The largest distance between the SL and PVBL was at L1 (5.22 ± 0.62 mm). From L1 to L5, the distance decreased progressively to 1.05 ± 0.64 mm. Similar variation was also observed from L1 to T1 (0.19 ± 0.18 mm). The postoperative computed tomography scan was more sensitive and accurate in detecting intraspinal leakage than radiography in group 1 (p = 0.000); however, there was no significant difference in sensitivity or accuracy between methods in group 2 (p = 0.063). The rate of intraspinal cement leakage was significantly higher in group 1 than group 2 (p = 0.000). Conclusions: The operator should frequently check to ensure that cement injection has stopped upon reaching the SL. Surgeons may benefit from this quantitative anatomical study of PKP and PVP.

RESUMO

BACKGROUND: Vertebral compression fracture is one of the most common complications of osteoporosis. In this study an unilateral curved vertebroplasty device was developed, and the safety, effectiveness, and surgical parameters of curved vertebroplasty (CVP) in the treatment of painful osteoporotic vertebral compression fractures was investigated and compared with traditional bipedicular vertebroplasty (BVP). METHODS: We investigated 104 vertebral augmentation procedures performed over 36 months. CVP and BVP procedures were compared for baseline clinical variables, pain relief (Visual Analog Scale, VAS), disability improvement (Oswestry Disability Index, ODI), operation time, number of fluoroscopic images, volume of cement per level, and cement leakage rate for each level treated. Complications and refracture incidence were also recorded in the two groups. RESULTS: The VAS and ODI in both group had no significant difference preoperative (P > 0.05), and a significant postoperative improvement in the VAS scores and ODI was found in both group (P < 0.001). However, the CVP group had significantly lower operation time, number of fluoroscopic images, and cement leakage rate per level than the BVP group (P < 0.05); however, the volumes of cement per level were similar in the two groups (P > 0.05). Neither group had any serious complications. Five and two patients in the BVP group developed refractures at non-adjacent and adjacent levels, respectively, with one patient developing refractures twice; however, none of the patients in the CVP group developed refractures at any level. CONCLUSIONS: Our findings revealed that both CVP and BVP were safe and effective treatments for osteoporotic vertebral compression fractures, and CVP entails a shorter operation time, less exposure to fluoroscopy, and lower rate of cement leakage.

RESUMO

BACKGROUND: The risk factors, incidence, and clinical management of pulmonary cement embolism and neurological deficit during percutaneous vertebroplasty (PVP) were evaluated. METHODS: Three thousand one hundred and seventy-five patients with symptomatic osteoporotic vertebral compression fractures (OVCFs) treated with PVP were retrospectively reviewed in a single institution. Clinical parameters such as age, gender, number of fractures, and time from fracture to vertebroplasty were recorded at the time of surgery. Image and surgical parameters including the amount of cement, the vertebral level, uni- or bipedicle surgical approach, and leakage pattern were recorded. RESULTS: Type-C leakage, including paraspinal (25%), intradiscal (26%), and posterior (0.7%) leakage, was more common than type-B (11.4%) and type-S leaks (4.9%). Cement leakage into the spinal canal (type-C posterior) occurred in 26 patients (0.7%), and four patients needed surgical decompression. Three in nine patients with leakage into thoracic spine needed decompressive surgery, but only one of 17 patients into lumbar spine needed surgery (p < 0.01). Age, gender, number of fractures, and time from fracture to vertebroplasty were not risk factors of pulmonary cement embolism or neurological deficit. The risk factor of pulmonary cement embolism was higher volume of PMMA injected (p < 0.001) and risk factor of neurological deficit was type-C posterior cement leakage into thoracic spine. The incidence of pulmonary cement embolism was significantly high in the volume of PMMA injected (PMMA injection < 3.5 cc: 0%; 3.5-7.0 cc: 0.11%; > 7.0 cc: 0.9%; p < 0.01) which needed postoperative oxygen support. CONCLUSIONS: Cement leakage is relatively common but mostly of no clinical significance. Percutaneous vertebroplasty in thoracic spine and high amount of PMMA injected should be treated with caution in clinical practice.

RESUMO

The aim of this study was to evaluate the safety and efficacy of percutaneous vertebroplasty (PVP) in Kambin triangle approach for the treatment of osteoporotic vertebral compression fractures (OVCFs).Between November 2017 and September 2018, 109 patients (144 vertebral bodies) with OVCFs, with a mean age of 76.7 ±â€Š9.9 years (55-96 years), underwent PVP in Kambin triangle approach. The time of operation, the volume of bone cement, the incidence of complication, the Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) score, the position of puncture needles, and the spread of polymethylmethacrylate (PMMA) in vertebral body (VB) were recorded.All patients had been completed the operation successfully and were followed up 9.1 ±â€Š2.9 months. The average operation time of each VB was 24.0 ±â€Š3.5 minutes. The average volume of cement was 4.8 ±â€Š0.6 ml. The mean VAS scores were 8.4 ±â€Š0.7 preoperatively, 1.6 ±â€Š0.6 at the first day postoperatively, and 1.2 ±â€Š0.6 at the last follow-up. The mean ODI scores were 70.97 ±â€Š7.73 preoperatively, 27.99 ±â€Š4.12 at the first day postoperatively, and 19.65 ±â€Š3.49 at the last follow-up. The position of puncture needles in the VB was: 119 vertebral puncture needles reached the midline, 15 were close to the midline, and 10 exceeded the midline. The spread of PMMA in the VB was: type 1 in 81 levels (56.3%), type 2 in 37 (25.7%), type 3 in 18 (12.5%), type 5 in 8 (5.5%), and no case in type 4. One case developed pneumothorax after operation. No other complications (hematoma, cement embolism, spinal cord, and nerve injury) occurred.Kambin triangle approach in PVP, which can deliver the puncture needle to the midline of VB easily and with excellent cement distribution, is a safe and effective method.

RESUMO

INTRODUCTION: This study aimed to assess the treatment effects of kyphoplasty (KP) compared with percutaneous vertebroplasty (VP) in patients with osteoporotic vertebral compression fracture, based on evidence from randomized controlled trials (RCTs). METHODS: The electronic databases PubMed (from 1966), EmBase (from 1974), and Cochrane Library (including Cochrane Central Register of Controlled Trials and Cochrane Reviews) were searched systematically to identify relevant studies published up to August 31, 2019. Meta-analyses were conducted for subjective pain as measured using visual analogue scale (VAS), disability function as measured by Oswestry disability index (ODI), and cement leakage. For VAS and ODI, mean change from the baseline and standard deviation were used; for cement leakage, numbers of events and patients in each group were used. The random-effects model was applied to summarize the effects across trials. RESULTS: Previous reviews and meta-analysis included non-RCTs, which brought (for those studies) a higher risk of bias. Therefore, 6 RCTs involving 1077 patients were included in the meta-analysis. No between-group difference was found. The weighted mean difference was -0.19 (95% confidence interval [CI], -0.39-0.01; P = .057) for VAS and -3.51 (95% CI, -8.70-1.67; P = .184) for ODI. However, KP had numerically lower rates of cement leakage across trials in a consistent fashion (relative risk, 0.83; 95% CI, 0.74-0.94; P = .004). CONCLUSIONS: Both KP and VP had clinically meaningful beneficial effects on pain and disability, and the effects were stable and similar. KP had significantly fewer cement leakages.

RESUMO

While vertebroplasty enjoys continued use in some settings, there is now high-moderate quality evidence based on systematic review that includes five placebo-controlled trials that it provides no benefits over placebo and these results do not differ according to pain duration (≤6 vs >6 weeks). A clinically important increased risk of incident symptomatic vertebral fractures or other serious adverse events cannot be excluded due to small event numbers. Serious harms including cord compression, ventricular perforation, pulmonary embolism, infection and death have been reported. This unfavourable risk-benefit ratio should be convincing doctors and patients to stop the use of vertebroplasty. At the very least, clinicians should fully inform their patients about the evidence including the likelihood of improving without vertebroplasty and the potential harms, so that patients can make evidence-informed decisions about their treatment. They should also warn patients about the pitfalls of relying on information sourced from the internet or from 'awareness raising' campaigns.
