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

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

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

Pain is a common source of suffering for seriously ill patients. Typical first-line treatments consist of lifestyle modifications and medication therapy, including opioids. However, medical treatments often fail or are associated with limiting systemic toxicities, and more targeted interventional approaches are necessary. Herein, we present options for minimally invasive techniques for the alleviation of pain in palliative patients from a head-to-toe approach, with a focus on emerging therapies and advanced techniques. Head and neck: image-guided interventions targeted to sympathetic ganglia of the head and neck, such as sphenopalatine ganglion (SPG) and stellate ganglion, have been shown to be effective for some forms of sympathetically-maintained and visceral pain. Interventions targeting branches of cranial nerves and upper cervical nerves, such as the glossopharyngeal nerve (GPN), are options in treating somatic head and face pain. Abdominal and pelvic: sympathetic blocks, including celiac plexus, inferior hypogastric, and ganglion impar can relieve visceral abdominal and pelvic pain. Spine and somatic pain: fascial plane blocks of the chest and abdominal wall and myofascial trigger point injections can be used for somatic pain indications. Cementoplasties, such as kyphoplasty and vertebroplasty, are used for pain related to bony metastases and compression fractures. Tumor ablative techniques can also be used for lytic lesions of the bone. Spinal cord stimulation (SCS), intrathecal drug delivery systems (IDDS), and cordotomy have also been used successfully in patients requiring advanced options, such as those with significant spinal, ischemic, or visceral pain.

A central function of health technology assessment (HTA) agencies is the production of HTA reports to support evidence-informed policy and decision making. HTA agencies are interested in understanding the mechanisms of HTA impact, which can be understood as the influence or impact of HTA report findings on decision making at various levels of the health system. The members of the International Network of Agencies for HTA (INAHTA) meet at their annual Congress where impact story sharing is one important activity. This paper summarizes four stories of HTA impact that were finalists for the David Hailey Award for Best Impact Story.The methods to measure impact include: document review; claims analysis and review of reimbursement status; citation analysis; qualitative evaluation of stakeholders' views; and review of media response. HTA agency staff also observed changes in government activities and priorities based on the HTA. Impact assessment can provide information to improve the HTA process, for example, the value of patient and clinician engagement in the HTA process to better define the assessment question and literature reviews in a more holistic and balanced way.HTA reports produced by publicly funded HTA agencies are valued by health systems around the globe as they support decision making regarding the appropriate use, pricing, reimbursement, and disinvestment of health technologies. HTAs can also have a positive impact on information sharing between different levels of government and across stakeholder groups. These stories show how HTA can have a significant impact, irrespective of the health system and health technology being assessed.

OBJECTIVE: To evaluate the analgesic effect of vertebral cancellous bone infiltration anaesthesia during percutaneous vertebroplasty (PVP). METHODS: Patients treated with vertebral cancellous bone infiltration anaesthesia (intervention group) or local anaesthesia alone (control group) during PVP at our institution during 2016-2018 were reviewed. The visual analogue scale (VAS) score before the operation, during establishment of the puncture channel, during pressure changes in the vertebral body (e.g., when removing or inserting pushers or needle cores), during bone cement injection, immediately after the operation, and at 2 h and 1 day postoperatively were compared between the groups. The patient's satisfaction with the operation was recorded and compared between groups. RESULTS: A total of 112 patients were enrolled (59 cases in the intervention group and 53 cases in the control group). There was no difference in the VAS score between the groups before the operation or during establishment of the intraoperative puncture channel (P > 0.05). The VAS score in the intervention group was significantly lower than that in the control group during pressure changes in the vertebral body (removal or insertion of puncture needle cores or pushers) and bone cement injection (P < 0.05). Immediately after the operation and at 2 h postoperatively, the pain in the intervention group was also significantly lower than that in the control group (P < 0.05), but there was no significant difference between the groups at 1 day postoperatively (P > 0.05). The patient satisfaction rate was 88% (52/59) in the intervention group and 67% (35/53) in the control group (P < 0.05). CONCLUSIONS: Vertebral cancellous bone infiltration anaesthesia may effectively relieve intraoperative pain and improve the surgical experience of patients without affecting the clinical effect of surgery.

Therapeutic advances in oncology have led to longer survival in many forms of cancer, including those complicated by bone metastases. When a bone metastasis is painful or when there is a risk of fracture, interventional radiology procedures can be carried out for pain control and/or stabilisation. All of these techniques can be performed under local anaesthesia. Cementoplasty and vertebroplasty are stabilisation procedures consisting in the percutaneous injection of acrylic cement into a lytic bone lesion. The effect on pain can be explained by the consolidation of weakened, fractured or pre-fractured bone, but also to a lesser extent by the toxic, chemical and thermal effect of the cement. Tumour ablation techniques include alcoholisation or thermal ablation (by heat with radiofrequency and microwave or cold by cryoablation). Percutaneous thermal ablation of bone tumours is most often performed as a palliative measure resulting in a significant and lasting reduction in symptoms. Radiofrequency ablation consists in placing needles through which an electrical current passes. Microwave ablation acts by causing very high frequency vibrations of water molecules. Cryoablation releases argon gas at the tip of the needle, forming an "ice ball" effectively destroying tumour cells. Any of these techniques can be combined to radiation therapy, performed before or after radiation. Finally, tumour embolisation can have a goal of pain control, or preparation of surgery to reduce the risk of peroperative haemorrhage.

OPINION STATEMENT: Spinal metastases are the most commonly encountered tumour of the spine, occurring in up to 40% of patients with cancer. Each year, approximately 5% of cancer patients will develop spinal metastases. This number is expected to increase as the life expectancy of cancer patients increases. Patients with spinal metastases experience severe and frequently debilitating pain, which often decreases their remaining quality of life. With a median survival of less than 1 year, the goals of treatment in spinal metastases are reducing pain, improving or maintaining level of function and providing mechanical stability. Currently, conventional treatment strategies involve a combination of analgesics, bisphosphonates, radiotherapy and/or relatively extensive surgery. Despite these measures, pain management in patients with spinal metastases is often suboptimal. In the last two decades, minimally invasive percutaneous interventional radiology techniques such as vertebral augmentation and radiofrequency ablation (RFA) have shown progressive success in reducing pain and improving function in many patients with symptomatic spinal metastases. Both vertebral augmentation and RFA are increasingly being recognised as excellent alternative to medical and surgical management in carefully selected patients with spinal metastases, namely those with severe refractory pain limiting daily activities and stable pathological vertebral compression fractures. In addition, for more complicated lesions such as spinal metastasis with soft tissue extension, combined treatments such as vertebral augmentation in conjunction with RFA may be helpful. While combined RFA and vertebral augmentation have theoretical benefits, comparative trials have not been performed to establish superiority of combined therapy. We believe that a multidisciplinary approach as well as careful pre-procedure evaluation and imaging will be necessary for effective and safe management of spinal metastases. RFA and vertebral augmentation should be considered during early stages of the disease so as to maintain the remaining quality of life in this patient population group.

Osteoporotic vertebral fractures constitute at least 50% of the osteoporotic fractures that happen worldwide. Occurrence of osteoporotic fractures make the elderly patient susceptible for further fractures and increases the morbidity due to kyphosis and pain; the mortality risk is also increased in these patients. Most fractures occur in the thoracic and thoracolumbar region and are often stable. Different descriptive and prognostic classification systems have been described, but none are universally accepted. Radiographs, computed tomography, and magnetic resonance imaging are useful in imaging the fracture and evaluating the bone density. In acute stages, the fractures are well treated with conservative measures including short bed rest, analgesics, bracing, and exercises. Although most fractures heal well, up to 30% of fractures can develop painful nonunion, progressive kyphosis, and neurological deficit. For patients who develop severe pain not responding to nonoperative measures and painful nonunion, percutaneous cement augmentation procedures including vertebroplasty or kyphoplasty have been suggested. For fractures with severe collapse and that lead to neurological deficit and increasing kyphosis, instrumented stabilization is advised. Prevention and management of osteoporosis is the key element in the management of osteoporotic fractures in the elderly. Guidelines for essential adequate dietary and supplemental calcium and vitamin D, and antiosteoporotic medications have been described.

Abstract Percutaneous vertebroplasty is a relatively safe, simple and commonly performed interventional procedure for the management of vertebral compression fractures. However, serious complications are rarely reported in the procedure. Those are pulmonary embolism, severe infection, paraplegia and an occurrence of a new fracture in an adjacent vertebra after vertebroplasty. Acute complications are generally associated with the procedure. We present the case of neuraxial anesthesia, developed after local anesthesia with 8 mL of 2% prilocaine, in a 68-year-old woman who underwent percutaneous vertebroplasty after an osteoporotic collapsed fracture in the L1 vertebra due to trauma. To our knowledge, this is the first case in the literature.
Resumo Vertebroplastia percutânea é um procedimento intervencionista relativamente seguro, simples e comumente feito para tratar fraturas por compressão vertebral. No entanto, as complicações graves relacionadas ao procedimento são raramente relatadas, incluindo embolia pulmonar, infecção grave, paraplegia e a ocorrência de uma nova fratura em vértebra adjacente após a vertebroplastia. Complicações agudas são geralmente associadas ao procedimento. Apresentamos o caso de bloqueio neuroaxial, feito após anestesia local com 8 mL de prilocaína a 2%, em uma mulher de 68 anos, submetida à vertebroplastia percutânea após fratura osteoporótica na vértebra L1 devido a trauma. De acordo com nossa pesquisa, este é o primeiro caso na literatura.

OBJECTIVE: Evaluate patients' intraoperative experience of percutaneous vertebroplasty (PV) performed without general anaesthesia in order to assess the feasibility of local anaesthesia and simple analgesic medication as pain control protocol. METHODS: Ninety-five patients who underwent single-site PV were consecutively included in the study between 2011 and 2013. Each procedure was achieved under local anaesthesia and perfusion of paracetamol, tramadol and dolasetron, with combined CT and fluoroscopy guidance. Numeric pain scale (NPS) was collected before, during and after intervention. After intervention, patients were asked to evaluate their experience as "very bad", "bad", "fair", "good" or "very good", independently of the pain. RESULTS: Indications for vertebroplasty were osteopenic fractures (78 %), aggressive angiomas (13 %) and somatic tumours (9 %). In 76 % of cases, patients' experience was described as "very good" (44 %) or "good" (32 %), whereas 19 % described it as "fair" and 5 % as "very bad". Mean operative NPS was 5.5. After intervention, NPS was significantly lower with a decrease of 4.5 points. No differences were found according to the localization, type of lesion, age or sex either in terms of experience or NPS. CONCLUSION: Percutaneous vertebroplasty is feasible under local anaesthesia alone, with a very good or good experience in 76 % of the patients. KEY POINTS: ⢠Vertebroplasty is a first-line therapy for consolidation and pain control of vertebral lesions. ⢠This procedure is commonly performed under general anaesthesia or conscious sedation. ⢠We perform vertebroplasty under local anaesthesia and simple analgesic protocol with acceptable experience. ⢠Percutaneous vertebroplasty can safely be proposed in a fragile population.

Polymethylmethacrylate (PMMA) bone cement is a popular bone void filler for vertebroplasty. However, the use of PMMA has some drawbacks, including the material's excessive stiffness, exothermic polymerization, and short handling time. This study aimed to create an ideal modified bone cement to solve the above-mentioned problems. Modified bone cements were prepared by combining PMMA with three different volume fractions of castor oil (5%, 10%, and 15%). The peak polymerization temperatures, times to achieve the peak polymerization temperature, porosities, densities, modulus and maximum compression strengths of standard (without castor oil), and modified cements were investigated following storage at ambient temperature (22°C) or under precooling conditions (3°C). Six specimens were tested in each group of the aforementioned parameters. Increasing castor oil content and precooling treatment effectively decreased the peak polymerization temperatures and increased the duration to achieve the peak polymerization temperature (P < 0.05). Furthermore, the mechanical properties of the material, including density, modulus, and maximum compression strength, decreased with increasing castor oil content. However, preparation temperature (room temperature versus precooling) had no significant effect (P > 0.05) on these mechanical properties. In conclusion, the addition of castor oil to PMMA followed by precooling created an ideal modified bone cement with a low modulus, low polymerization temperature, and long handling time, enhancing its applicability and safety for vertebroplasty.

Vertebroplasty is a minimally invasive procedure that may be performed under either local or general anesthesia. In this study, we aimed at assessing the outcomes of the vertebroplasty performed under local anesthesia in patients at high risk of general anesthesia. Vertebroplasty was performed under local anesthesia in the treatment of a total of 62 patients (68 vertebrae in total) with osteoporotic vertebral fractures between 2011 and 2013. None of the patients had a history of trauma. Patients who were classified as ASA III during the preoperative examinations were included in the study. VAS scores were evaluated before the surgery, on the first postoperative day, and in week 1 and in month 1 after the surgery. The average age was 77.5 years (age range 53-102). An average of 2 cc of cement was injected to 22 patients (35.5 %), and an average of 3 cc of cement was injected to 40 patients (64.5 %). The mean VAS scores were 7.52 (6-9) before the procedure, 3.55 (2-5) on the first day, 2.03 (0-4) in week 1 and 0.87 (0-2) in month 1 postoperatively. Asymptomatic cement embolism was detected in one patient. No other complications were observed in the study group. Vertebroplasty performed under local anesthesia is an effective and safe procedure in terms of pain control and early ambulation and is bereft of the complications associated with general anesthesia.

This paper selected and studied 15 in-hospital patients to analyze and discuss the clinical curative effect of percutaneous vertebroplasty (PVP) combined with (125)I-seed implantation in treating spinal metastatic tumor. The evaluation of clinical curative effects was based on the observation of several factors, namely recovery conditions of vertebral body's leading edge and middle section before and after surgery, improvements of kyphosis Cobb angle, visual analog scale (VAS), and Barthel Index (BI). The paper found significant difference between preoperative VAS and postoperative VAS, and the same situation occurred to BI. However, compared to the loss rate of vertebral body's leading edge and middle section and the improvement of Cobb angle before operative, postoperative loss rate and Cobb angle did not show statistical difference. Thus the conclusion is that PVP combined with (125)I-seed implantation is a minimally invasive surgery for effectively treating spinal metastatic tumor, which does well in rapidly releasing pains, improving patients' daily life activities and life qualities.

Spinal metastases of cancer are frequent and their treatment strategy remains a problem. The aim of the present paper is to present the technique of cementoplasty and its originality. Spine corporeal cementoplasty techniques were performed in 9 patients with spine metastasis treated at Neurosurgery Department between 2002 and 2005. This series is composed of four women and five men. The average age of patients was 54 years. All patients were admitted for treatment of metastasis of breast carcinoma, metastasis of breast adenocarcinoma (three cases), colon cancer (two cases), pulmonary adenocarcinoma (one case) and melanoma (three cases). Metastasis was located on the cervical spine (3 cases), thoracic spine (4 cases) and lumbar spine (2 cases). No case of cement leaking was observed. In eight patients neurological deficit and pain were decreased. In one patient we noted a persistence of neurological deficit but pain decreased. A post-operative radiological analysis showed good spine stability. Before their death this treatment had improved their quality of life. The technique of surgical cementoplasty described in this paper may be used for a surgical treatment of metastasis and spinal stabilisation. It is an alternative to a palliative treatment of metastasis when it is not possible to perform vertebroplasty.
