Abstract
Despite the recent advances in cancer treatment, the incidence of patients with spinal metastases continues to grow along with the total number of cancer patients. Spinal metastases can significantly impair activities of daily living (ADL) and quality of life (QOL), compared with other types of bone metastases, as they are characterized with severe pain and paralysis caused by skeletal-related events. Reduced ADL can also lead to treatment limitations as certain anticancer agents and radiation therapy are not compatible treatments; thus, leading to a shorter life expectancy. Consequently, maintaining ADLs in patients with spinal metastases is paramount, and spine surgeons have an integral role to play in this regard. However, neurosurgeon, orthopedic and spinal surgeons in Japan do not have a proactive treatment approach to spinal metastases, which may prevent them from providing appropriate treatment when needed (clinical inertia). To overcome such endemic inertia, it is essential for 1) spine surgeons to understand and be more actively involved with patients with musculoskeletal disorders (cancer locomo) and cancer patients; 2) the adoption of a multidisciplinary approach (coordination and meetings not only with the attending oncologist but also with spine surgeons, radiologists, rehabilitation specialists, and other professionals) to preemptive treatment such as medication, radiotherapy, and surgical treatment; and 3) the integration of the latest findings associated with minimally invasive spinal treatments that have expanded the indications for treatment of spinal metastases and improved treatment outcomes. This heralds a new era in the management of spinal metastases.

Radiofrequency Ablation in Vertebral Body Metastasis with and without Percutaneous Cement Augmentation: A Systematic Review Addressing the Need for SPINE Stability Evaluation. Diagnostics (Basel) 2023; 13:diagnostics13061164. [PMID: 36980472 PMCID: PMC10046948 DOI: 10.3390/diagnostics13061164] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 02/25/2023] [Accepted: 03/15/2023] [Indexed: 03/30/2023] Open
Abstract
Vertebral body metastases (VBM) are one of the most frequent sites of bone metastasis, and their adequate therapeutic management still represents an insidious challenge for both oncologists and surgeons. A possible alternative treatment for VBM is radiofrequency ablation (RFA), a percutaneous technique in which an alternating current is delivered to the tumor lesion producing local heating and consequent necrosis. However, RFA alone could alter the biomechanics and microanatomy of the vertebral body, thus increasing the risk of post-procedure vertebral fractures and spine instability, and indeed the aim of the present study is to investigate the effects of RFA on spine stability. A systematic review according to PRISMA-P guidelines was performed, and 17 papers were selected for the systematic review. The results show how RFA is an effective, safe, and feasible alternative to conventional radiotherapy for the treatment of VBM without indication for surgery, but spine stability is a major issue in this context. Although exerting undeniable benefits on pain control and local tumor recurrence, RFA alone increases the risk of spine instability and consequent vertebral body fractures and collapses. Concomitant safe and feasible therapeutic strategies such as percutaneous vertebroplasty and kyphoplasty have shown synergic positive effects on back pain and improvement in spine stability.

Abstract
OBJECTIVE To compare the safety and efficacy of posterior internal fixation with open vertebroplasty (VP) and posterior internal fixation with open kyphoplasty (KP) in the treatment of metastatic epidural spinal cord compression (MESCC) with posterior wall destruction. METHODS This retrospective study, conducted between January 2016 and May 2019, equally divided 60 patients with MESCC and posterior wall destruction into two groups based on the surgical method: open vertebroplasty with pedicle screw fixation (VP group) and open kyphoplasty with pedicle screw fixation (KP group). Visual analogue scale (VAS), SF-36 scores, middle vertebral height (MVH), and posterior vertebral height (PVH) were evaluated for the two groups preoperatively, postoperatively, and 1 year after surgery. Spinal Instability Neoplastic Score, Frankel grades and complications were recorded and evaluated. RESULTS Five patients were excluded from the analysis, and our study cohort consisted of 55 adult patients who met the inclusion criteria. The VAS and SF-36 scores of these two groups of patients significantly improved, when compared with those before the surgery (P < 0.05). There were significant differences in total cost (8835 ± 1468 vs 9540 ± 053 USD) and cement volume (4.51 ± 0.96 ml vs 6.35 ± 1.09 ml) between two groups (P < 0.05). The MVH and PVH of these two groups of patients significantly improved, when compared with those before the surgery (P < 0.05). The MVH was significantly larger in the KP group than in the VP group postoperatively (20.15 ± 4.86 vs 17.70 ± 3.78, P < 0.05) and at the final follow-up (20.42 ± 5.59 vs 17.28 ± 3.23, P < 0.05). However, the PVH of the two groups did not significantly differ at the two postoperative follow-ups (P > 0.05). No significant differences were found in surgery time, time from surgery to discharge, blood loss and complications between both groups postoperatively (P > 0.05). CONCLUSION In the short term, both approaches are effective and safe in patients with MESCC and posterior wall destruction. The posterior internal fixation with open VP may be a good choice of surgical method in patients with MESCC and posterior wall defects.

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

Abstract
OBJECTIVE This abbreviated version of the American College of Occupational and Environmental Medicine's Low Back Disorders guideline reviews the evidence and recommendations developed for invasive treatments used to manage low back disorders. METHODS Comprehensive systematic literature reviews were accomplished with article abstraction, critiquing, grading, evidence table compilation, and guideline finalization by a multidisciplinary expert panel and extensive peer-review to develop evidence-based guidance. Consensus recommendations were formulated when evidence was lacking and often relied on analogy to other disorders for which evidence exists. A total of 47 high-quality and 321 moderate-quality trials were identified for invasive management of low back disorders. RESULTS Guidance has been developed for the invasive management of acute, subacute, and chronic low back disorders and rehabilitation. This includes 49 specific recommendations. CONCLUSION Quality evidence should guide invasive treatment for all phases of managing low back disorders.

Acta Neurochir (Wien) 2020; 162:2533-2536.

Abstract
BACKGROUND Metastatic cervical spine disease can cause compression fractures, cervical spine instability, and pain. Vertebroplasty can stabilize a fracture, reduce the pain associated with a compression fracture, prevent or stop the progression of a fracture, thus avoiding cervical spine fixation, and decreased mobility. Transoral C2 vertebroplasty is less invasive than open fusion surgery, but it poses its own risk of infection and cement leak in this highly sensitive area. METHODS The image guidance setup consisted of the Stryker NAV3i navigation system, Stryker CranialMask tracker, and the CranialMap 3.0 software combined with biplanar fluoroscopy. RESULTS The patient's neck pain has completely resolved immediately after the surgery. There were no complications. CONCLUSION Quality of life preservation is paramount in the management of metastatic spine disease. Vertebroplasty of osteolytic lesions can both relieve pain and restore stability, thus avoiding permanent stiff cervical collar, halo vest, or upfront occipitocervical fusion. With the increasing availability of surgical navigation systems, its use combined with biplanar fluoroscopy for performing transoral C2 vertebroplasty seems to be an adequate treatment in selected cases for pain relief, stabilization, and maintaining quality of life in the complex cancer population with C2 pathological fractures. The article describes as well vertebroplasty of the subaxial spine through a conventional anterior approach which again seems to be adequate in the treatment of spinal pathological fractures.

Abstract
Background Extensile interventions to provide anterior spinal column support in metastatic spinal cord compression (MSCC) surgery incur added morbidity in this surgically frail group of patients. We present our preliminary results of posterior spinal decompression and stabilization coupled with vertebral body cemented stents for anterior column support in MSCC. Methods Fourteen patients underwent posterior spinal decompression and pedicle screw construct along with vertebral body stenting (VBS) technique for reconstruction and augmentation of the vertebral body. The primary in all except one was solid organ malignancy and 10 patients (71%) were treatment naïve. The mean revised Tokuhashi score was 10.7 ± 2.7 and the mean spinal instability neoplastic score was 9.6 ± 1.9. All vertebral body lesions were purely lytic and were associated with a cortical defect in the posterior wall. Results A mean 5.3 ± 2.7 ml low-viscosity polymethyl methacrylate bone cement was injected within the stent at each compression level. No cement extrusion posteriorly was noted in any case from intraoperative fluoroscopy or postoperative radiographs. Five patients died at a mean 6.8 months (range 1-15 months), while the remaining patients have a mean survival of 18 months. Neither further revision surgical intervention nor any neurological deterioration was noted in any patient, who all continued to be ambulatory. The mean postoperative Core Outcome Measures Index score for 11 patients was 4.03 (standard deviation 3.11, 95% confidence interval (1.93-6.12). Conclusion In lytic vertebral body lesions with posterior wall erosions, cemented VBS technique adds to the surgical armamentarium in MSCC surgery showing promising early results without added complications.

Abstract
PURPOSE To investigate the surgical effects of modified kyphoplasty with controllable balloon dilatation for treatment of thoracolumbar osteoporotic vertebral compression fractures (OVCF). METHODS From April 2013 to October 2017, a total of 53 patients with thoracolumbar OVCF were treated with controllable balloon percutaneous kyphoplasty (C-PKP). Peri-operative parameters including days from injury to operation, operation time, injected cement volume, cement leakage and complications were collected. Visual analogue scale (VAS) and Cobb angle before and after operation were applied to evaluate surgical effects. Moreover, a total of 53 cases treated with traditional balloon of percutaneous kyphoplasty were retrospectively analyzed and compared with C-PKP in above parameters. RESULTS C-PKP achieved significant fewer events of cement leakage (type C) than that of traditional PKP (5/53 vs 13/53, p < 0.01). The patients were followed up for 10.8 ± 4.2 months; VAS and Cobb angle of the injured vertebra in both two groups at three days and final follow-up were significantly improved compared with that before surgery (p < 0.05), while there were no significant differences between the two groups regarding the VAS and Cobb angle at corresponding time points (p > 0.05). CONCLUSIONS C-PKP technology is a safe and efficient way for the treatment of thoracolumbar OVCF, and it can reduce cement leakage.

Abstract
Bone metastasis is a common complication of cancer, and bone is the third most common metastatic site following the lung and liver. Among the various bones, spine is the most common site of metastatic tumors. The treatment goals of patients with spinal metastases are mostly palliative, with the aim of reducing pain and improving quality of life. The treatment of spinal metastases has made significant progress over the past few decades. Each new technology has tried to solve the shortcomings of its predecessors. Currently, there are no mature algorithms or specific techniques that have proven to be the best for spinal metastases, and the treatment method often relies on operator and institutional preferences or biases in some cases. Percutaneous vertebral augmentation has unique value in the management of spinal metastases, understanding its indications, surgical techniques, uses, advantages and complications is critical to providing optimal patient care. We believe that the application of percutaneous vertebral augmentation alone or combined with other techniques can achieve optimal pain relief and functional improvement in the patients with spinal metastases.

Abstract
Background Kyphoplasty (KP) is a palliative treatment for patients with metastatic vertebral tumors. The distribution pattern of cement affects safety and efficacy. The distribution pattern of cement has not been previously reported for patients with metastatic vertebral tumors. Material/Methods From January 2013 to December 2017, patients with metastatic vertebral tumors who met our criteria were divided into cement fusion (n=91) and separation (n=97) groups. Visual analogue scale (VAS) and middle vertebral height (MVH) were evaluated preoperatively, postoperatively, and 1 year after surgery. Spinal Instability Neoplastic Score, fluoroscopy time, operation time, cement volume, cement leakage, and vertebral fractures were recorded and evaluated. Results Compared with the fusion group, the separation group had significantly different (P<0.001) operation time, fluoroscopy time, and cement volume. Compared with preoperative status, VAS and MVH were significantly improved 3 days postoperatively and 1 year postoperatively in both groups (P<0.001). The difference in cement leakage between the 2 groups (P<0.05) and in the number of adjacent vertebral fractures between the 2 groups (P<0.05) were significant. Conclusions The distribution patterns of the bone cement had a good analgesic effect and preventive effect on vertebral collapse. However, the separation of bone cement may be safer.

Abstract
STUDY DESIGN Systematic review. OBJECTIVES To assess the efficacy of kyphoplasty in controlling pain and improving quality of life in oncologic patients with metastatic spinal disease and pathologic compression fractures of the spine. METHODS A literature search through medical database was conducted (using PubMed, EMBASE, Cochrane, and LILACS) for randomized controlled trials comparing balloon kyphoplasty versus the traditional treatment for compression fractures of the spine due to metastatic disease. Two investigators independently assessed all titles and abstracts to select potential articles to be included. Inclusion criteria consisted of randomized controlled trials involving patients with pathologic compression fractures due to spinal metastasis or multiple myeloma treated with balloon kyphoplasty procedure as one of the study interventions, while the control group was any other treatment modality. The risk of bias in individual studies was assessed. RESULTS Two studies, with a combined total of 181 patients, met inclusion criteria. Because of data heterogeneity, the meta-analysis was not possible, and individual analysis of studies was performed. There is moderate evidence that patients treated with balloon kyphoplasty displayed better scores for pain (Numeric Rating Scale), disability (Roland-Morris Disability Questionnaire), quality of life (Short Form-36 Health Survey), and functional status (Karnofsky Performance Status) compared with those undergoing the conventional treatment. Patients treated with kyphoplasty also have better recovery of vertebral height. CONCLUSIONS This study concluded that balloon kyphoplasty could be considered as an early treatment option for patients with symptomatic neoplastic spinal disease, although further randomized clinical trials should be performed for improvement of the quality of evidence.

Abstract
OBJECTIVE Symptomatic metastatic spine disease (MSD), is a challenging disease involving 3%-20% of patients with bone metastases. Different surgical options are available and must be tailored to the general and neurologic conditions of the patients. Open kyphoplasty (OKP) refers to decompressive hemilaminectomy, associated with a contralateral percutaneous kyphoplasty, and in some cases, to a posterior stabilization. The aim of the study was to critically review our experience during the last decade with OKP in patients with cancer. METHODS Fifty-three patients with cancer underwent OKP for symptomatic MSD. The Tokuhashi score and Spinal Instability Neoplastic Score were calculated for each patient. Length of hospital stay, perioperative complications, incidence of adjacent-level fractures, and median survival after surgery were evaluated. Karnofsky Performance Status, visual analog scale, and Dennis Pain Score were calculated preoperatively, postoperatively, and at last follow-up. RESULTS Median Tokuhashi score and Spinal Instability Neoplastic Score were 10 and 10, respectively. The mean volume of filling material inserted was 3.6 mL. Median operative time was 180 minutes. Complications included 8 leakages (15%), 2 permanent motor deficits (3.8%), and 2 asymptomatic pulmonary embolisms (3.8%). Mean length of hospital stay was 7 days. A significant improvement was observed in Karnofsky Performance Status, visual analog scale score, and Dennis Pain Score (P < 0.0001). Median follow-up was 16 months and overall survival 22 months. CONCLUSIONS OKP was an effective treatment of symptomatic MSDs in selected oncologic patients with low Tokuhashi scores. It relieved lateral epidural compressions, expanded indications of palliative surgery in patients who were not otherwise surgical candidates, and rapidly dealt with cement leakages.

Abstract
Multiple Myeloma (MM) is primarily a disease of old age with a median age of sixty-nine years at diagnosis. The development of novel therapies for induction and use of autologous stem cell transplantation has resulted in improved clinical outcomes and better quality of life for MM patients. Elderly patients, comprising the majority of MM population, have a higher incidence of age-related comorbidities, frailty and organ dysfunction which complicates the coordination of treatment and limits the selection of therapies. Even in the era of multiple chemotherapeutic options, the clinical heterogeneity of the myeloma patients' demands personalized treatments which often require dose-adjustments or dose delays. The use of reduced-dose regimens and various comorbidity indices has improved clinical outcome and regimen tolerability in MM patients with renal, neurological and bone abnormalities. We focus on advancements in the treatment of multiple myeloma with the goal to guide clinicians towards patient-specific management.

The role of cement augmentation with percutaneous vertebroplasty and balloon kyphoplasty for the treatment of vertebral compression fractures in multiple myeloma: a consensus statement from the International Myeloma Working Group (IMWG). Blood Cancer J 2019; 9:27. [PMID: 30808868 PMCID: PMC6391474 DOI: 10.1038/s41408-019-0187-7] [Citation(s) in RCA: 43] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2018] [Revised: 09/09/2018] [Accepted: 10/31/2018] [Indexed: 12/26/2022] Open
Abstract
Multiple myeloma (MM) represents approximately 15% of haematological malignancies and most of the patients present with bone involvement. Focal or diffuse spinal osteolysis may result in significant morbidity by causing painful progressive vertebral compression fractures (VCFs) and deformities. Advances in the systemic treatment of myeloma have achieved high response rates and prolonged the survival significantly. Early diagnosis and management of skeletal events contribute to improving the prognosis and quality of life of MM patients. The management of patients with significant pain due to VCFs in the acute phase is not standardised. While some patients are successfully treated conservatively, and pain relief is achieved within a few weeks, a large percentage has disabling pain and morbidity and hence they are considered for surgical intervention. Balloon kyphoplasty and percutaneous vertebroplasty are minimally invasive procedures which have been shown to relieve pain and restore function. Despite increasing positive evidence for the use of these procedures, the indications, timing, efficacy, safety and their role in the treatment algorithm of myeloma spinal disease are yet to be elucidated. This paper reports an update of the consensus statement from the International Myeloma Working Group on the role of cement augmentation in myeloma patients with VCFs.

Abstract
UNLABELLED Kümmell's disease (eponymous name for osteonecrosis and collapse of a vertebral body due to ischemia and non-union of anterior vertebral body wedge fractures after major trauma) cannot heal spontaneously. Bone-filling mesh container (BFMC) can significantly relieve pain, help the correction of kyphosis, and may prevent cement leakage. This pilot study may provide the basis for the design of future studies. PURPOSE To compare the effectiveness and safety of BFMC and percutaneous kyphoplasty (PKP) for treatment of Kümmell's disease. METHODS From August 2016 to May 2018, 40 patients with Kümmell's disease were admitted to Guizhou Provincial People's Hospital. Among them, 20 patients (20 vertebral bodies) received PKP (PKP group) and the other 20 received BFMC (BFMC group). Operation time, Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), Cobb's angle changes, and related complications were recorded. RESULTS All patients underwent operations successfully. VAS scores and ODI of both groups at each postoperative time point were lower than preoperatively, with statistically significant difference (p < 0.05). Postoperative Cobb's angle of both groups postoperatively was lower than preoperatively (p < 0.05). Cement leakage occurred in eight vertebrae (8/20) in the PKP group and in one vertebra (1/20) in the BFMC group. No complications such as pulmonary embolism, paraplegia, or perioperative death occurred during operation in both groups. Adjacent vertebral refractures occurred in five patients (5/20) in the PKP group and in four patients (4/20) in the BFMC group, with no significant difference in the incidence rate of refractures in both groups but the material is too small to verify statistically. CONCLUSIONS Both PKP and BFMC technologies can significantly relieve pain and help the correction of kyphosis while treating Kümmell's disease. Moreover, the BMFC may prevent cement leakage.

Abstract
Discuss the relevant literature on surgical and nonsurgical treatments for multiple myeloma (MM) and their complementary effects on overall treatment. Existing surgical algorithms designed for neoplasia of the spine may not suit the management of spinal myeloma. Less than a fifth of metastatic, including myelomatous lesions, occur in the cervical spine but have a poorer prognosis and surgery in this area carries a higher morbidity. With the advances of chemotherapy, early access to radiotherapy, early orthosis management, and high definition imaging, including CT and MRI, surgical indications in MM have changed. Medical decompression (or oncolysis), including in the presence of neurological deficit and orthotic stabilization, are proving viable nonsurgical options to manage MM. A key to decision making is the assessment and monitoring of biomechanical spinal stability as part of a multidisciplinary approach.

Abstract
Purpose Minimally invasive spine stabilization (MISt) using percutaneous pedicle screws plays a significant role in palliative surgery for metastatic spinal tumors. However, few studies have investigated surgical outcomes based on the epidural spinal cord compression scale (ESCCS). The purpose of this study was to examine outcomes of metastatic spinal tumors as evaluated by ESCCS in patients treated by MISt. Methods The subjects were 56 patients who underwent MISt for metastatic spinal tumors, including 34 patients with ESCCS 2 or milder (group A) and 22 patients with ESCCS 3 (group B). We analyzed baseline characteristics, perioperative factors and clinical results such as postoperative survival time, neurological outcomes, Barthel Index for activities of daily living (ADL), visual analogue scale (VAS), and the rate of discharge to home. Results The baseline age (P=0.07), tumor diagnosis (P=0.23), spinal level of compression (P=0.35), American Spinal Injury Association classification (P=0.49), revised Tokuhashi score (P=0.92), spinal instability neoplastic score (P=0.28), VAS (P=0.35), Barthel Index (P=0.07), American Society of Anesthesiologists physical status classification (P=0.76), and type of surgery (P=0.40) did not differ significantly between the two groups. The median postoperative survival time did not differ significantly between the groups (12.0 versus 15.0 months, P=0.60). Neurological improvement by at least 1 grade or maintenance of grade E was favorable in group A. Patients in group A had less posterior decompression (P=0.006), a higher rate of chemotherapy (P=0.009), a higher postoperative Barthel Index (P=0.04), and a higher rate of discharge to home (P=0.01) and no patients died in the hospital (P=0.004). Conclusions No significant difference was noted in the postoperative survival time between the 2 groups. Patients in the ESCCS 2 or milder group had favorable neurological improvement, higher rates of chemotherapy, better postoperative ADL, and the higher rate of discharge to home.

Abstract
INTRODUCTION The spine is the most common site of bone metastases. Vertebroplasty (VP) and kyphoplasty (KP) have been proposed as potential minimally invasive therapeutic options for metastatic spinal lesion (MSL) pain. However, the efficacy of VP and KP on MSL pain is currently unclear. OBJECTIVE The aim of this study was to assess the effects of VP and KP compared with each other, usual care, or other treatments on pain, disability, and quality of life following MSL. METHODS We included randomized controlled trials and prospective nonrandomized controlled clinical trials assessing VP or KP for the treatment of pain following MSL without cord compression. We searched MEDLINE, EMBASE, PubMed, and CENTRAL. RESULTS The literature search revealed 387 citations. Of these, 9 trials met all eligibility criteria and were included in the qualitative analysis. In total, there were 622 patients enrolled in the trials and of them 432 were in the surgical treatment group (92 received KP, 97 received VP, 134 received VP and chemotherapy, 68 received VP and radiotherapy, and 41 received Kiva implant) and 190 were in the nonsurgical treatment group (83 received chemotherapy, 46 received radiotherapy, and 61 received other treatment). Using the grading of recommendations assessment, development and evaluation approach, pain (low-quality evidence) and functional scores (very low-quality evidence) improved more with VP plus chemotherapy than with chemotherapy alone (pain: mean difference, -3.01; 95% confidence interval, -3.21 to -2.80; functional score: mean difference, 15.46; 95% confidence interval, 13.58-17.34). KP seemed to lead to significantly greater improvement in pain, disability, and health-related quality of life (HRQoL) compared with nonsurgical management. VP plus Iodine-125 seemed to lead to significantly greater improvement in pain and disability in comparison with VP alone. VP plus radiochemotherapy resulted in better pain relief and HRQoL postoperatively in comparison with routine radiochemotherapy. There was low-quality evidence to prove that surgical treatment significantly decreases pain, and improves functional score and HRQoL following MSL in comparison with nonsurgical management. CONCLUSION On the basis of the analysis of currently published trial data, it is unclear whether VP for MSL provides benefits over KP. LEVEL OF EVIDENCE Level 2.

Abstract
OBJECTIVE The treatment of cervical spinal metastases represents a controversial issue regarding the type, extent, and invasiveness of interventions. In the lumbar and thoracic spine, kypho- and vertebroplasties have been established as minimally invasive procedures for patients with metastases to the vertebral bodies and without neurological deficit. These procedures show good results with respect to pain reduction and low complication rates. However, limited data are available for kypho- and vertebroplasties for cervical spinal metastases. In an effort to add to existing data, the authors here present a case series of 14 patients who were treated for osteolytic metastases of the cervical spine using vertebroplasty alone or in addition to another surgical procedure involving the cervical spine in a palliative setting to reduce pain and restore stability. METHODS Fourteen patients consisting of 8 males and 6 females, with a mean age of 64.7 years (range 44-85 years), were treated with vertebroplasty at the authors' clinic between January 2015 and November 2016. In total, 25 vertebrae were treated with vertebroplasty: 10 C-2, 5 C-3, 2 C-4, 2 C-5, 3 C-6, and 3 C-7. Two patients had an additional posterior stabilization and 5 patients an additional anterior stabilization. In 13 cases, the surgical approach was a modified Smith-Robinson approach; in 1 case, the cement was injected into the corpus axis from posteriorly. Patients with osteolytic defects of the posterior wall of the vertebral body did not undergo surgery, nor did patients with neurological deficits. Preoperatively, on the 2nd day after surgery, and at the follow-up, neck pain was rated using the visual analog scale (VAS). RESULTS Twelve patients were examined at follow-up (mean 9 months). Neck pain was rated as a mean of 6.0 (range 3-8) preoperatively, 2.9 on Day 2 after surgery (range 0-5), and 0.5 at the follow-up (range 0-4), according to the VAS. The mean Neck Disability Index at follow-up was 3.6% (range 0%-18%). CONCLUSIONS Anterior vertebroplasty of the cervical spine via an anterolateral approach represents a safe and minimally invasive procedure with a low complication rate and appears suitable for reducing pain and restoring stability in cases of cervical spinal metastases. Vertebroplasties can be combined with other anterior and posterior operations of the cervical spine and, in the axis vertebra, can be performed transpedicularly from posteriorly. Thus, in cases in which the posterior wall of the vertebral body is intact, vertebroplasty represents a less invasive alternative to vertebral replacement in oncological surgery. Prospective randomized trials with a longer follow-up period and a larger patient cohort are needed to confirm the encouraging results of this case series.

Abstract
Background Posterior decompression and stabilization plays significant roles in palliative surgery for metastatic spinal tumor. However, the indication for addition of posterior decompression have not been examined. The purpose of this study was to investigate a retrospective cohort of outcomes of metastatic spinal tumor treated with minimally invasive spine stabilization (MISt) with or without posterior decompression. Methods The subjects were 40 patients who underwent MISt using percutaneous pedicle screws for metastatic spinal tumor, including 20 patients treated with stabilization alone (group A) and 20 patients with added posterior decompression (group B). We analyzed baseline characteristics, postoperative survival time, and perioperative factors such as neurological outcomes, Barthel Index, VAS, and rate of discharge to home. Results The mean ages were 70 and 66 years old (P = 0.06), the mean revised Tokuhashi scores were 7.2 and 5.8 (P = 0.1), the mean spinal instability neoplastic scores (SINS) were 10.5 and 9.0 (P = 0.04), and the mean Barthel Index for ADL were 65.5 and 41.0 (P = 0.06) in groups A and B, respectively. The median postoperative survival time did not differ significantly between groups A and B (12.0 vs. 6.0 months, P = 0.09). Patients in group A had a significantly shorter operation time (166 vs. 232 min, P = 0.004) and lower intraoperative blood loss (120 vs. 478 mL, P < 0.001). Postoperative paralysis (P = 0.1), paralysis improvement rate (P = 0.09), postoperative Barthel Index (P = 0.06), and postoperative VAS (P = 0.6) did not differ significantly between the groups. The modified Frankel classification improved from D1 or D2 before surgery to D3 or E after surgery in 4 of 10 cases (40%) in group A and 8 of 8 patients (100%) in group B (P = 0.01). Significantly more patients were discharged to home in group A (P = 0.02), whereas significantly more patients died in the hospital in group B (P = 0.02). Conclusions Patients treated without decompression had a shorter operation time, less blood loss, a higher rate of discharge to home, and lower in-hospital mortality, indicating a procedure with lower invasiveness. MISt without decompression is advantageous for patients with D3 or milder paralysis, but decompression is necessary for patients with D2 or severer paralysis.

Clinical results of multidisciplinary therapy including palliative posterior spinal stabilization surgery and postoperative adjuvant therapy for metastatic spinal tumor. J Orthop Surg Res 2018; 13:30. [PMID: 29402333 PMCID: PMC5799906 DOI: 10.1186/s13018-018-0735-z] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2017] [Accepted: 01/24/2018] [Indexed: 01/13/2023] Open
Abstract
Background Surgeries performed for metastatic spinal tumor are mostly palliative and are controversial for patients with short life expectancy. We investigated whether palliative posterior spinal stabilization surgery with postoperative multidisciplinary therapy results in improvement of life prognosis and activities of daily living (ADL) in patients with metastatic spinal tumor. Methods The subjects were 55 patients who underwent palliative posterior-only instrumentation surgery for metastatic spinal tumor at our hospital between 2012 and 2015. Postoperative survival, early paralysis improvement, ADL improvement, and rate of discharge to home were examined. Results The patients included 37 males and 18 females, and the mean age at the time of surgery was 66.8 years old. The mean Tokuhashi score was 7.1, the mean spinal instability neoplastic score (SINS) was 9.4, and the epidural spinal cord compression scale (ESCCS) was grade 3 in 20 patients (36.3%). The mean Barthel index for ADL was 48.7. The median postoperative survival time determined using the Kaplan-Meier method was 12.0 months (95% confidence interval 2.4–21.5). Regarding improvement of paralysis, the modified Frankel scale was improved by one grade or more or grade E was maintained in 35 patients (63.6%), whereas paralysis aggravated in 2 (3.6%). In surgery, conventional posterior decompression and fixation were applied in 31 patients (56.3%), and minimally invasive spine stabilization was applied in 24 (43.6%). Postoperative chemotherapy was performed in 31 patients (56.3%), radiotherapy was used in 38 (69.0%), and a bone-modifying agent was administered in 39 (70.2%). Regarding ADL, the mean Barthel index improved from 48.5 before surgery to 74.5 after surgery. Thirty-seven patients (67.2%) were discharged to home. Conclusions ADL improved and allowed discharge to home, and postoperative adjuvant therapy could be administered at a high rate in patients who received palliative posterior spinal stabilization surgery. Survival time extended beyond the preoperative life expectancy in many patients. Patients with a metastatic spinal tumor have short life expectancy and paralysis caused by spinal instability and spinal cord compression. However, multidisciplinary therapy including palliative posterior spinal stabilization surgery with reduced invasiveness and postoperative adjuvant therapy are effective in these patients.

Abstract
Aims and background Kyphoplasty is an effective procedure providing structural stability and pain alleviation in vertebral metastases. To prevent early regrowth, patients typically receive postoperative fractionated radiotherapy, which is associated with long treatment duration. Therefore, we established a new approach to deliver intraoperative radiotherapy during kyphoplasty to shorten the treatment time and reach structural stability and sterilization of the metastases (Kypho-IORT). Methods and study design For Kypho-IORT, a 50 kV X-ray source with a specially designed applicator was used. A radiation dose of 8 Gy in 5 mm distance was delivered. After radiation the device was removed and the kyphoplasty was completed according to the standard procedure. Since August 2009, 18 patients with instable or painful spinal metastases received Kypho-IORT. The median age was 63 years (range, 43–73). Results Kypho-IORT was successfully performed in 18 of 21 vertebral lesions (86%). No severe complications occurred during or early after IORT. The median pain score using a visual analogue scale decreased from 5/10 before the procedure to 2.5/10 at day 1 (P <0.001) and to 0/10 six weeks after the procedure (P = 0.001). Imaging studies were available for 15 of 18 patients. Stable disease within the irradiated vertebral body was seen in 14 patients (93%) and local progressive disease in one patient (7%). No re-irradiation due to local progressive disease or pain recurrence was necessary within the median follow-up of 4.5 months. Conclusions Kypho-IORT is well tolerated without severe side effects and provides fast improvement of pain. Although stable disease was seen in 93% of the patients, a longer follow-up is necessary to assess the effectiveness. A dose escalation study to establish the maximally tolerated dose has been initiated.

Abstract
BACKGROUND Myeloma patients often suffer from painful vertebral fractures (VCF) which impair their quality of life. Common methods for augmentation of the vertebrae are vertebroplasty, kyphoplasty and radiofrequency-targeted vertebral augmentation (RF-TVA). OBJECTIVE This study evaluates the long-term effectiveness and safety of RF-TVA in the treatment of myeloma associated VCF. METHODS Eighty-seven myeloma patients (mean age: 64.7 ± 9.5 years) with VCF were treated with RF-TVA. Patient data were assessed preoperatively and in five postoperative examinations up to 12 months. Pain was measured with the visual analogue scale (VAS) and the impairment was evaluated with the Oswestry-Disability-Index (ODI) at each examination. In addition, the mid vertebral height, kyphosis angle, and additional fractures were evaluated by x-rays. Furthermore, cement leakage was documented. RESULTS The VAS values were significantly improved in comparison to the preoperative values (p≤ 0.001), but slightly fluctuating during the follow-up period. The ODI was also significantly improved (p≤ 0.001), but it showed a worsening from the 12 months evaluation to the 24 months evaluation. The kyphosis angle and the vertebral height were significantly improved after surgery (p = 0.03, p ≤ 0.001), but worsened steadily to the last follow up examination. Cement leakage was asymptomatic and occurred in 18% of the patients. In 10% of the patients additional fractures were detected in the 24 months evaluation. CONCLUSIONS The results of our study show that RF-TVA is a safe treatment for myeloma associated vertebral compression fractures, which achieves an acceptable improvement of patient's pain and quality of life.

Abstract
Unfortunately, osteoporosis, as a worldwide disease, is challenging human health with treatment only available for the symptoms of osteoporosis without managing the disease itself. Osteoporosis can be linked as the common cause of fractures and increased mortality among post-menopausal women, men, and the elderly. Regrettably, due to osteoporosis, incidents of fractures are more frequent among the presented populations and can be afflictive for carrying out everyday life activities. Current treatments of osteoporosis encompass changing lifestyles, taking orthopedic drugs, and invasive surgeries. However, these treatment options are not long lasting and can lead to complications after post-surgical life. Therefore, to solve this impairment, researchers have turned to nanotechnologies and nanomaterials to create innovative and alternative treatments associated with the consequences of osteoporosis. This review article provides an introduction to osteoporotic compression vertebral fractures (OVCFs) and current clinical treatments, along with the rationale and efficacy of utilizing nanomaterials to modify and improve biomaterials or instruments. The methods of applying bioactive agents (bone morphogenetic protein-2 (BMP-2), parathyroid hormone 1-34 (PTH 1-34)), as well as 3D printing will be presented from an osteoporosis treatment perspective. Additionally, the application of nanoparticles and nanotube arrays onto the current surgical treatments and orthopedic drug administration methods addressed will show that these systems reinforce a better mechanical performance and provide precise and slow-releasing drug delivery for better osseointegration, bone regeneration, and bone strength. In summary, nanomaterials can be seen as an alternative and more effective treatment for individuals with osteoporosis.

Vertebral Augmentation Involving Vertebroplasty or Kyphoplasty for Cancer-Related Vertebral Compression Fractures: A Systematic Review. ONTARIO HEALTH TECHNOLOGY ASSESSMENT SERIES 2016; 16:1-202.

Abstract
BACKGROUND Cancers that metastasize to the spine and primary cancers such as multiple myeloma can result in vertebral compression fractures or instability. Conservative strategies, including bed rest, bracing, and analgesic use, can be ineffective, resulting in continued pain and progressive functional disability limiting mobility and self-care. Surgery is not usually an option for cancer patients in advanced disease states because of their poor medical health or functional status and limited life expectancy. The objectives of this review were to evaluate the effectiveness and safety of percutaneous image-guided vertebral augmentation techniques, vertebroplasty and kyphoplasty, for palliation of cancer-related vertebral compression fractures. METHODS We performed a systematic literature search for studies on vertebral augmentation of cancer-related vertebral compression fractures published from January 1, 2000, to October 2014; abstracts were screened by a single reviewer. For those studies meeting the eligibility criteria, full-text articles were obtained. Owing to the heterogeneity of the clinical reports, we performed a narrative synthesis based on an analytical framework constructed for the type of cancer-related vertebral fractures and the diversity of the vertebral augmentation interventions. RESULTS The evidence review identified 3,391 citations, of which 111 clinical reports (4,235 patients) evaluated the effectiveness of vertebroplasty (78 reports, 2,545 patients) or kyphoplasty (33 reports, 1,690 patients) for patients with mixed primary spinal metastatic cancers, multiple myeloma, or hemangiomas. Overall the mean pain intensity scores often reported within 48 hours of vertebral augmentation (kyphoplasty or vertebroplasty), were significantly reduced. Analgesic use, although variably reported, usually involved parallel decreases, particularly in opioids, and mean pain-related disability scores were also significantly improved. In a randomized controlled trial comparing kyphoplasty with usual care, improvements in pain scores, pain-related disability, and health-related quality of life were significantly better in the kyphoplasty group than in the usual care group. Bone cement leakage, mostly asymptomatic, was commonly reported after vertebroplasty and kyphoplasty. Major adverse events, however, were uncommon. CONCLUSIONS Both vertebroplasty and kyphoplasty significantly and rapidly reduced pain intensity in cancer patients with vertebral compression fractures. The procedures also significantly decreased the need for opioid pain medication, and functional disabilities related to back and neck pain. Pain palliative improvements and low complication rates were consistent across the various cancer populations and vertebral fractures that were investigated.

Percutaneous vertebroplasty for patients with metastatic compression fractures of the thoracolumbar spine: clinical and radiological factors affecting functional outcomes. Spine J 2016; 16:355-64.

Abstract
BACKGROUND CONTEXT Vertebroplasty (VP), including balloon kyphoplasty (BKP), has long been accepted as a minimally invasive surgical intervention for the stabilization of painful vertebral compression fractures. In metastatic compression fracture (MCF), cancer often invades the paravertebral structure and involves the posterior column of the vertebrae. PURPOSE In the present study, we first analyzed how clinical features of MCF affect functional outcomes after VP. Second, we evaluated whether BKP is more beneficial than simple VP (SVP) in MCF. STUDY DESIGN/SETTING This is a retrospective observational study. PATIENT SAMPLE Three hundred forty-two patients who underwent VP for painful MCF from solid cancer were included. We excluded MCF from hematopoietic cancer, such as leukemia or multiple myeloma. OUTCOME MEASURES Pain improvement was evaluated using the visual analog scale (VAS; range: 0-10), and if the VAS score decreased by at least three points the treatment was considered effective. Postoperative change in Karnofsky performance status (KPS) and drug requirement for pain control were also measured as functional outcomes. METHODS An institutional database at the National Cancer Center of Korea was searched to identify all patients who underwent VP for painful MCF between March 2002 and September 2013. Demographic data, as well as preoperative and postoperative clinical factors, were collected from patients' medical records. Radiological features, including paravertebral extension of tumors and the extent of three-column involvement, were reviewed from pretreatment magnetic resonance imaging (MRIs). These clinical and radiological factors were then analyzed for their influence on functional outcomes. RESULTS The mean preoperative VAS score was 5.8; this improved to a mean of 2.7 after VP. Effective improvement in VAS score (≥3) was achieved in 206 patients (60%). Patients with radiculopathy, as well as those with involvement of (1) the posterior column or (2) more than four out of six columns, presented with significantly higher pretreatment VAS scores and experienced more effective improvement after treatment (p<.05). Two hundred thirty-eight patients (70%) underwent SVP, whereas the remaining 104 patients underwent BKP. The pretreatment degree of compression was significantly higher in BKP (mean: 47%) than in SVP patients (mean: 30%) (p<.001). However, preoperative VAS scores were not significantly different between the two groups, and the resultant VAS score improvement was also not significantly different. Although BKP patients reported to have a greater chance of more than 3 mL of cement injection (p=.01), the mean amount of cement injected was not different between the two groups. Patients with other bone metastases showed a significantly poorer KPS improvement rate (p=.015). Patients having moderately or slowly growing cancer according to the Tomita classification had a greater chance of reduced drug requirements 1 month after the procedure (p=.004). CONCLUSIONS Paravertebral extension and posterior column involvement of MCF did not preclude pain improvement after VP. Balloon kyphoplasty for MCF failed to show enhanced pain improvement relative to SVP. Metastatic compression fracture patients with other bone metastases or rapidly growing tumors had a lower chance of performance improvement and reduced drug requirements, respectively.

Abstract
PURPOSE Pain is the most common symptom in cancer patients. Standard pain treatment according to the WHO three-step analgesic ladder provides effective pain management in approximately 70-90% of cancer patients. Refractory pain is defined as not responding to "standard" treatments. Interventional analgesic techniques can be used in an attempt to control refractory pain in patients in whom conventional analgesic strategies fail to provide effective pain relief or are intolerable due to severe adverse effects. This systematic review aims to provide the latest evidence on interventional refractory pain management in cancer patients. METHODS Systematic literature search in Cochrane, EMBASE and PubMed including reviews and randomised controlled trials (RCTs) and non-randomised controlled trials in the absence of reviews. RESULTS Neuraxial analgesia may play a role in refractory cancer pain management. Paravertebral blocks decrease the incidence of persistent post-surgical pain after breast cancer. Coeliac plexus blocks improve pain scores in refractory pancreatic cancer pain for up to 4 weeks after the intervention with fewer burdensome side effects as compared to opioids. Cordotomy has mainly been studied in mesothelioma, and the case series suggest possible benefit for pain at the expense of a relatively high risk of side effects. CONCLUSIONS Overall, very few RCTs have been conducted on interventional pain techniques. In reality, it is very difficult to undertake large controlled trials for a number of reasons. Therefore, today's best evidence for practice may be from large case series of comparable patients with careful response and toxicity evaluation and follow-up.

Abstract
BACKGROUND CONTEXT Meta-analyses are powerful tools that can synthesize existing research, inform clinical practice, and support evidence-based care. These studies have become increasingly popular in the spine surgery literature, but the rigor with which they are being conducted has not yet been evaluated. PURPOSE Our primary objectives were to evaluate the methodological quality (credibility) of spine surgery meta-analyses and to propose strategies to improve future research. Our secondary objectives were to evaluate completeness of reporting and identify factors associated with higher credibility and completeness of reporting. STUDY DESIGN This study is based on a systematic survey of meta-analyses. OUTCOME MEASURES We evaluated credibility according to the Users' Guide to the Medical Literature and completeness of reporting according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. METHODS We systematically searched MEDLINE, EMBASE, and The Cochrane Library, and two reviewers independently assessed eligibility, credibility, and completeness of reporting. We used multivariable linear regression to evaluate potential associations. Interrater agreement was quantified using kappa and intraclass correlation (ICC) coefficients. RESULTS We identified 132 eligible meta-analyses of spine surgery interventions. The mean credibility score was 3 of 7 (standard deviation [SD], 1.4; ICC, 0.86), with agreement for each item ranging from 0.54 (moderate) to 0.83 (almost perfect). Clinical questions were judged as sensible in 125 (95%), searches were exhaustive in 102 (77%), and risk of bias assessments were undertaken in 91 (69%). Seven (5%) meta-analyses addressed possible explanations for heterogeneity using a priori subgroup hypotheses and 24 (18%) presented results that were immediately clinically applicable. Investigators undertook duplicate assessments of eligibility, risk of bias, and data extraction in 46 (35%) and rated overall confidence in the evidence in 24 (18%). Later publication year, increasing Journal Impact Factor, increasing number of databases, inclusion of Randomized Controlled Trials, and inclusion of non-English studies were significantly associated with higher credibility scores (p<.05). The mean score for reporting was 18 of 27 (SD, 4.4; ICC, 0.94). CONCLUSIONS The credibility of many current spine surgery meta-analyses is limited. Researchers can improve future meta-analyses by performing exhaustive literature searches, addressing possible explanations of heterogeneity, presenting results in a clinically useful manner, reproducibly selecting and assessing primary studies, addressing confidence in the pooled effect estimates, and adhering to guidelines for complete reporting.

Abstract
Osteoporosis is a serious public health problem affecting hundreds of millions of aged people worldwide, with severe consequences including vertebral fractures that are associated with significant morbidity and mortality. To augment or treat osteoporotic vertebral fractures, a number of surgical approaches including minimally invasive vertebroplasty and kyphoplasty have been developed. However, these approaches face problems and difficulties with efficacy and long-term stability. Recent advances and progress in nanotechnology are opening up new opportunities to improve the surgical procedures for treating osteoporotic vertebral fractures. This article reviews the improvements enabled by new nanomaterials and focuses on new injectable biomaterials like bone cements and surgical instruments for treating vertebral fractures. This article also provides an introduction to osteoporotic vertebral fractures and current clinical treatments, along with the rationale and efficacy of utilizing nanomaterials to modify and improve biomaterials or instruments. In addition, perspectives on future trends with injectable bone cements and surgical instruments enhanced by nanotechnology are provided.

Abstract
The clinical presentation of AL amyloidosis is highly variable. In this series, we describe five cases of AL amyloidosis with vertebral compression fractures as initial presentation. All five patients had evidence of bone marrow replacement on magnetic resonance imaging and bone marrow biopsies demonstrating diffuse interstitial amyloid deposition. Hepatomegaly and elevated liver enzymes, consistent with liver involvement with amyloidosis, were also seen in each case. All five patients responded well to anti-plasma cell chemotherapy, with normalization of serum free light chain levels, reduction in alkaline phosphatase and improvement in pain and functional status. Although rare, AL amyloidosis should be considered in the differential diagnosis of selected patients with spontaneous vertebral compression fractures. Moreover, there seems to be an association of vertebral compression fractures with liver involvement in AL amyloidosis.

Abstract
Leiomyosarcoma is a rare malignant tumor derived from smooth muscle cells, which commonly metastasizes to the lungs, liver, kidney, brain and skin. The current study presents the case of a 42-year-old male who presented with progressive neck pain and numbness of the left arm. Spinal computed tomography and magnetic resonance imaging revealed osteolytic lesions of numerous vertebrae (C2, C3, C4, C5, C6, C7, T1 and T2). With regard to the C6 vertebra, total destruction of the vertebral body resulted in vertebral collapse and subsequent spinal cord compression. The patient underwent an anterior C6 corpectomy, reconstruction with a mesh cage filled with polymethyl methacrylate (PMMA) and open PMMA infusion to C5 and C7. The surgical procedure significantly alleviated the symptoms and obtained a reliable reconstruction. The clinical follow-up examination at 13 months was uneventful with the exception of mild numbness of the left hand since the surgery. To the best of our knowledge, this is the first case of leiomyosarcoma recurrence presenting in the cervical spine, and the present study provides insight into the use of a surgical technique that has rarely been used in the cervical spine.

Abstract
Background Thoracolumbar vertebral metastasis (TVM) affects a large number of cancer patients. However, safe and effective palliative care remains controversial. The aim of the present study was to investigate the safety and efficacy of minimally invasive image-guided radiofrequency ablation (RFA) with percutaneous kyphoplasty (PKP) for TVM treatment. Material/Methods A retrospective study of 26 patients (mean age: 59.31±11.62 years) was conducted, including 38 vertebral metastases at T11, T12, L1, L2, L3, L4, L5, and S1 with abundant blood vessels. Patients underwent RFA with PKP (4–6 min, 95±5°C, 150 W, effective electrode area of 1.5–2.0 cm) under general anesthesia from February 2005 to January 2009. Electrodes were inserted into the lesions and pre- and post-operative visual analog scale (VAS) scores and X-rays were collected on day 3, week 1, and months 1, 3, and 6. Tumor recurrence and pain level were also evaluated. Safety assessment was conducted based on complications and adverse events. The mean follow-up time was 8.4±2.1 months. Results A mean of 2.69±0.93 ablation was performed per patient. The ablation procedure required a mean of 15.08±4.64 min, while the injection of bone cement required a mean of 6.73±0.83 min, for a mean total operating time of 47.77±7.13 min. Postoperative VAS scores were significantly lower on day 3, week 1, and months 1, 3, and 6 (P<0.01), without any complications or tumor recurrence. Conclusions Image-guided RFA with PKP was safe and effective for TVM treatment when used with careful consideration of bone cement volume/viscosity, injection location, and temperature.

Abstract
STUDY DESIGN Retrospective assessment of risk factors using univariate and multivariate analyses. OBJECTIVE To evaluate risk factors retrospectively for cement leakage (CL), including vascular cement leakage (vCL) and cortical cement leakage (cCL), in percutaneous vertebroplasty of spinal metastasis. SUMMARY OF BACKGROUND DATA Complications of vertebroplasty for spine metastasis are rare but related to extravertebral cement leakage that is pulmonary embolism and medullary compression. Better understanding of the risk factors for vascular and cortical types of cement leakage is necessary to prevent these complications. METHODS Fifty-six cancer patients (30 females, 26 males; age, 56 ± 12 yr) (81 vertebrae) were treated in 58 sessions under fluoroscopy or computed tomography-fluoroscopy guidance. Leakage rates were reported. The following items were assessed for occurrence of CL, vCL, and cCL: primary tumor site, prior radiotherapy or local tumor ablation or embolization, appearance on computed tomography, cortical osteolytic destruction, vertebral collapse, operator's experience, guidance modality, and cement filling. RESULTS CL, vCL, and cCL rates were 53%, 25%, and 32%. History of prior treatment correlated with a decrease in CL (P = 0.018). vCL decreased when lung was the primary tumor site (P = 0.036), in osteolytic vertebrae (P = 0.033) or when there was a vertebral collapse (P = 0.037). cCL correlated with operator's experience (P = 0.021) and vertebral collapse (P < 0.001). Superior discal cCL correlated with superior endplate cortical destruction (P = 0.012). Although history of prior treatment seemed to be an independent protective factor (odds ratio = 0.24; 95% confidence interval, 0.087-0.7; P = 0.001), vertebral collapse was isolated as a risk factor for cCL (odds ratio = 32; 95% confidence interval, 6.7-161; P = 0.001). CONCLUSION Risk factors for cCL and vCL are distinct. Vertebral collapse and cortical destruction are risk factors for cCL. History of prior treatment is a protective factor for CL.

Abstract
BACKGROUND AND PURPOSE Studies examining the efficacy of vertebroplasty and kyphoplasty in patients with vertebral fractures from multiple myeloma are limited. We sought to perform a systematic review of published case studies examining changes in pain, disability, and analgesic drug use in patients with multiple myeloma who have undergone vertebral augmentation. MATERIALS AND METHODS We performed a pooled analysis of published case series of vertebral augmentation in patients with multiple myeloma. Twenty-three studies (9 kyphoplasty, 12 vertebroplasty, and 2 of both) with data on 923 patients were identified from a PubMed search. Quantitative outcome data included the Visual Analog Scale, the Brief Pain Inventory, the Short Form 36 Health Survey, and the Owestry Disability Index. Time periods were consolidated into 3: postoperatively ≤1 week, 1 week to 1 year, and ≥1 year. Change in analgesic use was also studied. Data were compared by using nonparametric tests and matched t tests for temporally linked data. RESULTS Patients achieved a decrease in pain across all consolidated time periods. Pain, as measured on a 10-point scale, decreased by 4.8 points up to 1 week, 4.6 points up to 1 year, and 4.4 points after a year (P < .001). Decrease in pain was apparent early after treatment and was sustained with time. Kyphoplasty and vertebroplasty were equally effective in reducing pain scores because differences between procedures for each time period were insignificant (P < .9 for <1 week, P < 1.0 for ≤1 year, and P < .9 for >1 year. CONCLUSIONS Our analysis demonstrates that vertebral augmentation is effective in patients with multiple myeloma.

Abstract
STUDY DESIGN Multicenter randomized controlled trial. OBJECTIVE To compare the efficacy and safety of balloon kyphoplasty (BKP) with nonsurgical management (NSM) during 24 months in patients with painful vertebral compression fractures (VCFs). SUMMARY OF BACKGROUND DATA Recently, several large randomized controlled trials have been conducted and reported how vertebral augmentation compares with NSM for patients with acute VCFs. Few of these trials report on the surgical aspects and radiographical vertebral deformity results. METHODS Adults with 1 to 3 VCFs were randomized within 3 months of pain to undergo bilateral BKP (n = 149) or NSM (n = 151). Surgical parameters, subjective quality of life assessments and objective functional (timed up and go) and radiographical assessments were collected. RESULTS Compared with NSM, the BKP group had greater improvements in SF-36 physical component summary (PCS) scores at 1 month (5.35 points; 95% CI, 3.41-7.30; P < 0.0001) and when averaged across the 24 months (overall treatment effect 2.71 points; 95% CI, 1.34-4.09; P = 0.0001). The kyphoplasty group also had greater functionality by assessing timed up and go (overall treatment effect -2.49 s; 95% CI, -0.82 to -4.15; P = 0.0036). At 24 months, the change in index fracture kyphotic angulation was statistically significantly improved in the kyphoplasty group (average 3.13° of correction for kyphoplasty compared with 0.82° in the control, P = 0.003). Number of baseline prevalent fractures (P = 0.0003) and treatment assignment (P = 0.004) are the most predictive variables for PCS improvement; however, in patients who underwent BKP, there may also be a link with kyphotic angulation. In BKP, the highest quart for kyphotic angulation correction had higher PCS improvement (13.4 points) than the quart having lowest correction of angulation (7.40 points, P = 0.0146 for difference). The most common adverse events temporally related to surgery (i.e., within 30 d) were back pain (20 BKP, 11 NSM) new VCF (11 BKP, 7 NSM), nausea/vomiting (12 BKP, 4 NSM), and urinary tract infection (10 BKP, 3 NSM). Several other adverse events were possibly related to patient positioning in the operating room. CONCLUSION Compared with NSM, BKP improves patient quality of life and pain averaged during 24 months and results in better improvement of index vertebral body kyphotic angulation. Perioperative complications may be reduced with more care in patient positioning. LEVEL OF EVIDENCE 2.

Abstract
PURPOSE The aim of the International Myeloma Working Group was to develop practice recommendations for the management of multiple myeloma (MM) -related bone disease. METHODOLOGY An interdisciplinary panel of clinical experts on MM and myeloma bone disease developed recommendations based on published data through August 2012. Expert consensus was used to propose additional recommendations in situations where there were insufficient published data. Levels of evidence and grades of recommendations were assigned and approved by panel members. RECOMMENDATIONS Bisphosphonates (BPs) should be considered in all patients with MM receiving first-line antimyeloma therapy, regardless of presence of osteolytic bone lesions on conventional radiography. However, it is unknown if BPs offer any advantage in patients with no bone disease assessed by magnetic resonance imaging or positron emission tomography/computed tomography. Intravenous (IV) zoledronic acid (ZOL) or pamidronate (PAM) is recommended for preventing skeletal-related events in patients with MM. ZOL is preferred over oral clodronate in newly diagnosed patients with MM because of its potential antimyeloma effects and survival benefits. BPs should be administered every 3 to 4 weeks IV during initial therapy. ZOL or PAM should be continued in patients with active disease and should be resumed after disease relapse, if discontinued in patients achieving complete or very good partial response. BPs are well tolerated, but preventive strategies must be instituted to avoid renal toxicity or osteonecrosis of the jaw. Kyphoplasty should be considered for symptomatic vertebral compression fractures. Low-dose radiation therapy can be used for palliation of uncontrolled pain, impending pathologic fracture, or spinal cord compression. Orthopedic consultation should be sought for long-bone fractures, spinal cord compression, and vertebral column instability.

Abstract
The authors endeavor to highlight the surgical management of severe neurological deficit resulting from cement leakage after percutaneous vertebroplasty and to systematically review the literature on the management of this complication. A patient presented after a vertebroplasty procedure for traumatic injury. A CT scan showed polymethylmethacrylate leakage into the right foramina at T-11 and L-1 and associated central stenosis at L-1. He underwent decompression and fusion for removal of cement and stabilization of the fracture segment. In the authors' systematic review, they searched Medline, Scopus, and Cochrane databases to determine the overall number of reported cases of neurological deficit after cement leakage, and they collected data on symptom onset, clinical presentation, surgical management, and outcome. After surgery, despite neurological recovery postoperatively, the patient developed pneumonia and died 16 days after surgery. The literature review showed 21 cases of cement extravasation with neurological deficit. Ultimately, 15 patients had resolution of the postoperative deficit, 5 had limited change in neurological status, and 2 had no improvement. Cement augmentation procedures are relatively safe, but certain precautions should be taken to avoid such complications including high-resolution biplanar fluoroscopy, considering the use of a local anesthetic, and controlling the location of cement spread in relationship to the posterior vertebral body. Immediate surgical intervention with removal of cement provides good results with complete recovery in most cases.

Abstract
Study design: Comparative effectiveness review. Study rationale: The spine is among the most common location for bony metastases. In many cases these metastases cause fractures leading to increased morbidity. Percutaneous cement augmentation techniques have been developed over the past decades for the treatment of these fractures; however, there are little data comparing these interventions. Clinical question: Do comparative studies of vertebral cement augmentation for fractures caused by spinal tumors provide evidence of improved patient outcomes? Methods: A systematic search and review of the literature was undertaken to identify studies published through June 8, 2011. Two individuals independently reviewed articles based on inclusion and exclusion criteria which were set a priori. Each article was evaluated using a predefined quality-rating system and an overall strength of evidence determined. Results: The literature consists primarily of case series. Only two studies comparing vertebroplasty with kyphoplasty were found. Pain scores in both treatment groups were significantly decreased relative to preoperative scores and appear to have been sustained at follow-up times to 1 year. It is unclear whether one treatment provided superior pain relief than the other. Both studies reported decreased analgesic use after both treatments but neither study compared use between treatment groups. Balloon rupture occurred in one kyphoplasty patient in one study and extravasation of polymethylmethacrylate (PMMA) cement into the anterior perivertebral soft tissue was seen in another patient in the vertebroplasty group and no patients in the kyphoplasty group in the other study. No other intraoperative or postoperative complications occurred. Conclusions: There is only limited evidence from comparative studies (two small retrospective cohort studies) regarding the benefits of vertebroplasty versus kyphoplasty in patients with spinal fractures caused by tumors. Both appear to be effective in reducing pain with relatively few complications. Whether one method provides superior results over the other cannot be determined from the available evidence. Study limitations preclude making definitive conclusions. The overall strength of evidenced is very low.

Abstract
UNLABELLED Patients with painful vertebral compression fractures produced by multiple myeloma (MM) often experience reduction in pain after spinal augmentation with kyphoplasty or vertebroplasty. Previous studies have shown pain reduction and improvement in functional status after augmentation, but no studies have examined the effect of augmentation on other cancer-related symptoms. We hypothesized that reduction in pain severity would be significantly associated with improvement in other reported symptoms. We retrospectively studied 79 patients who rated pain and symptom severity both before and after kyphoplasty or vertebroplasty. Pain was significantly reduced after spinal augmentation (1.3 on a 0 to 10 scale; effect size [ES] = .59; P < .001), as were anxiety (1.3; ES = .47), drowsiness (1.3; ES = .39), fatigue (1.1; ES = .32), depression (.7; ES = .28), and difficulty thinking clearly (.7; ES = .26) (all P < .05). Greater reduction in pain was associated with a greater number of symptoms being reduced. Interestingly, insomnia worsened regardless of any amount of improvement in pain. Because appropriate symptom control contributes to the overall well-being of cancer patients, future studies of pain reduction procedures should include measures of other symptoms to fully characterize the potential benefit of treating pain. PERSPECTIVE Appropriate symptom control contributes to overall well-being for cancer patients. This study demonstrated that pain reduction after spinal augmentation with vertebroplasty or kyphoplasty was positively associated with reduction in other patient-reported cancer-related symptoms. Future studies of these augmentation procedures should measure multiple symptoms, in addition to pain and functional status.

Cement leakage as a possible complication of balloon kyphoplasty--is there a difference between osteoporotic compression fractures (AO type A1) and incomplete burst fractures (AO type A3.1)? Acta Neurochir (Wien) 2012; 154:313-9.

Abstract
BACKGROUND Besides the treatment of osteoporotic vertebral compression fractures of AO type A1, balloon kyphoplasty (BKP) is seen as a therapeutic option even in the treatment of incomplete osteoporotic burst fractures (AO type A3.1). However, due to involvement of the posterior vertebral body wall, the risk of cement leakages is considered to be higher. This study focuses on the frequency and pattern of cement leakages in AO type A3.1 fractures compared with osteoporotic compression fractures (AO type A1). PATIENTS AND METHODS Retrospective cohort analysis was done of all patients (n = 138) treated by BKP for osteoporotic vertebral fractures (n = 173) between January 2007 and December 2010 in our department. Cement extravasations into three pre-defined anatomical compartments were evaluated on postoperative CT scans of the augmented vertebral bodies, with even minor cement detections beyond the vertebral body's wall being strictly inidicated as leakages. The frequency of cement leakages in relation to the fracture type was statistically analyzed using Pearson's chi-square test. Clinical and radiological follow-up was done 6 weeks, 3 and 6 months postoperatively. RESULTS The overall cement leakage rate of BKP in 173 treated osteoporotic vertebral fractures was 30.6%. Cement extravasations were detected in 20.3% of A1.1, 30.5% of A1.2, 37.8% of A1.3, and 39.0% of A3.1 fractures, respectively. There was no statistically significant difference in the leakage rate between A3.1 and all A1 fractures (28.0%; p > 0.05), but between A3.1 and A1.1 fractures (p < 0.05). Intraspinal cement extravasations, being the most dangerous, were seen in 25.5% of all leakages (n = 53), whereas in relation to the total number of treated fracture types, there were only 5.1% intraspinal leakages in A1.1, 5.6% in A1.2, 10.9% in A1.3, and 9.8% in A3.1 fractures. Two of 13 patients with intraspinal leakages and 1 patient with a paraaortal anterolateral cement extravasation needed surgical revisions. Two pulmonary PMMA cement embolisms were detected, but without any clinical consequences. None of the patients with cement leakages during BKP suffered from new neurological deficits. CONCLUSIONS Cement leakages remain a problem in BKP. Although there was no significant difference between AO type A3.1 and all A1 fractures, subgroup analysis revealed a statistically significant higher risk of cement extrusions in A3.1 compared to A1.1 fractures. None of the affected patients showed new neurological deficits due to cement extravasations. Still, balloon kyphoplasty can be considered a safe procedure, even in the treatment of painful osteoporotic vertebral fractures of AO type A3.1.

Indications and contraindications for vertebroplasty and kyphoplasty. Arch Orthop Trauma Surg 2010; 130:765-74.

Abstract
INTRODUCTION Vertebral fractures (VF) are a leading cause of morbidity in the elderly. In the past decade, minimally invasive bone augmentation techniques for VF, such as percutaneous vertebroplasty (VP) and kyphoplasty (KP) have become more widespread. According to the literature, both techniques provide significant pain relief. However, KP is more expensive and technically more demanding than VP. The current study surveyed German surgeons who practice percutaneous augmentation to evaluate and compare decisions regarding the implementation of these techniques. Is there a difference in the indications and contraindications of VP and KP compared with the interdisciplinary consensus paper on VP and KP of the German medical association in the treatment of VF? METHODS A multiple choice questionnaire was designed with questions regarding diagnostic procedures, clinical and radiologic (AO classification) indications, as well as contraindications for both VP and KP. A panel of five experts refined the initial questionnaire. The final version was then sent to 580 clinics registered to practice KP in Germany. The statistical analysis was done by two authors, who collected the questionnaire data and Wilcoxon's signed ranks test was performed for non-parametric variables with SPSS. RESULTS 327 of 580 questionnaires (56.4%) were completed and returned. 151 (46.2%) of participants were performing both procedures, and 176 (53.8%) performed KP only. Median duration from onset of acute pain to intervention was 3 weeks. For most participants (95.4%), consistent back pain at the fracture level with a visual analog scale score over 5 was the main clinical indication for VP and KP. A1 and A3.1 fractures from osteoporosis and metastasis were considered indications for KP. Osteoporotic A1.1 fractures were an indication for VP. Traumatic A3.2 fractures were not an indication for either procedure. Major contraindications to both procedures were active infection (94.7%), cement allergy (86.8%), and coagulation disorders (80.3%). CONCLUSION Vertebroplasty and kyphoplasty both have roles in the treatment of vertebral fractures. However, we could see differences in the indications for the two percutaneous techniques. Participants of this study found more indications for KP versus VP in cases of painful A1.2 and A3.1 fractures due to osteoporosis, metastasis, and trauma. About half of the respondents reported that VP is indicated for osteoporotic and pathologic A1.1 fractures. This study offers only limited conclusions. Open questionnaires and prospective data from all clinicians performing these procedures should be analyzed to offer more specific information.
