The ISASS Policy Statement on vertebral augmentation has the objectives to provide a background and an update with the latest clinical evidence for the international spine community. A SpineLine Panel Review (2010) appropriately recommended an exploration of ‘‘the seeming disconnect between the conclusions of . . . two [Level I] PRCT’s and previous experience and data’’ regarding vertebral augmentation. ISASS responded by supporting a comprehensive meta-analysis to help frame a cogent historical analysis of vertebral augmentation. This ISASS Policy 2018 is based on a thorough literature search for relevant studies, including systematic reviews and meta-analyses, that are subjected to thorough quality appraisal for the purpose of informing public opinion and decision making. Given the abundance of high-quality information, ISASS can confidently advocate that there is strong support for vertebral augmentation in the treatment of symptomatic vertebral compression fractures.


Vertebral compression fractures (VCFs) are extremely prevalent and are a hallmark of osteoporosis. The overall age- and sex-adjusted incidence is 117 per 100 000 persons per year (145 per 100 000 women per year; 73 per 100 000 men per year).1 These fractures result in pronounced pain in addition to a negative impact on the patient’s function and quality of life. Osteoporosis is the most frequent cause for VCFs and is the most important potentially modifiable risk factor for VCFs. Other etiologies, such as neoplasm, trauma, or underlying infection, may also predispose patients to fractures.

Conservative management (bracing and optimal pain management) does not provide adequate long-term pain control while increasing the mortality and morbidity risks of patients secondary to higher risks of cardiac complications and pneumonia.2 Moreover, surgical instrumentation has limited utility, as the fixation may not provide sufficient mechanical stability,3 resulting in residual pain. Pedicle screws have an additional risk of loosening in osteoporotic bone.4–6

VCFs can be treated with minimally invasive interventions, such as percutaneous vertebroplasty and kyphoplasty. Vertebroplasty consists of positioning a trocar (range 8 to 13 gauge) within the vertebral body via a small skin puncture. Cement is then injected with a small cannula with image guidance (fluoroscopic or computed tomography [CT]). Kyphoplasty has similar steps to vertebroplasty; however, a cavity is created within the cancellous bone of the vertebral body prior to cement injection. This cavity can be created in various ways, including with a balloon and a mechanical bone tamp or other mechanical device(s), with the intent of restoring the vertebral body height before filling it with bone cement.

There are 2 types of cement currently available in the United States polymethylmethacrylate (PMMA) and a bioactive calcium phosphate micro-glass cement (Cortoss; Stryker, Malvern, Pennsylvania). PMMA polymerizes and transitions from a liquid to a solid form via an exothermic reaction. The final state of the PMMA does not resorb over time and has an impressive capacity to sustain compressive forces (90 to 110 MPa). Cortoss is a nonresorbable composite that was developed specifically for vertebral augmentation unlike its older time-proven alternative, PMMA. It consists of 33% difunctional methacrylates that form a cross-linked 3-dimensional polymer reinforced with 67% of bioactive glass ceramic.7 This composite is stronger than PMMA and of similar strength to cortical bone with a much lower exothermic reaction (approximatively 60°C with Cortoss versus 70°C-90°C with PMMA).7,8

The principal goal of vertebral augmentation is to fill the fracture cleft with cement to provide vertebral body mechanical stability. It is this mechanical stability that provides pain relief. The second goal of performing an augmentation procedure is to improve the sagittal alignment and biomechanics of the functional spinal unit (complex of adjacent vertebra). This optimization decreases the probability of refracture within the vertebral body and adjacent-level fractures. Meta-analysis of the literature has demonstrated that vertebral augmentation decreases the prevalence of adjacent-level fracture;9 this is also supported by recent biomechanical experiments.10


Typically, vertebral compression fractures are characterized by pain exacerbated by standing erect or with a change of positions (mechanical symptoms). Closed-fist percussion has a sensitivity and specificity of 87.5% and 90%, respectively.11 Advanced imaging is recommended prior to performing vertebral augmentation (magnetic resonance imaging [MRI], CT, or bone scan). When available, MRI should be done.

When left untreated, VCFs significantly increase patients’ morbidity and mortality. Cauley et al12 demonstrated that the age-adjusted relative risk of dying was actually higher following a vertebral compression fracture in comparison to a hip fracture (8.64 and 6.68, respectively). Lau et al13 additionally demonstrated that patients with VCFs have a 40% lower survival rate at 8 years. Multiple other studies demonstrated the same rationale with a significant increase in mortality and morbidity in patients treated with nonsurgical management when compared to patients who benefited from vertebral augmentation (Table 1).2,14–17

NSM: 30% and 8% higher mortality risk at 1 year and 10 years than VP (propensity adjusted: 95% CI 8%-9%, P < .001)

Injectable cement remains the main building block for the treatment of painful VCFs. Acrylic-based cements were the first type of cement used to treat fractures in the 1980s. Indeed, the first use of acrylic-based cement (PMMA) in the spine was performed by Galibert et al18 in 1987 as a way to stabilize a vertebral hemangioma. Since then, more than 52 level 1 and level 2 studies were published9,19 with the overwhelming majority in favor of the use of vertebral augmentation; some of those studies are shown in Table 2. It is now difficult to argue against the effectiveness of these minimally invasive interventions. Although some studies have argued against the use of vertebral augmentation, questions about the methodological or technical aspects of those studies have been raised. In summary, 3 studies failed to demonstrate superiority of vertebroplasty against a “sham” treatment.20–22 The sham treatments utilized in those 3 studies were in fact active treatments. Moreover, the amount of cement injected was either not reported21 or clearly insufficient (ie, an average of 2.8 cc in the Buchbinder et al20 study and ranging from 1 to 11 cc in the Firanescu et al22 study). Others have also detailed flaws of the construct of those studies related to patient selection, low visual analog scale (VAS) score at baseline, and underpowered studies23,24 as well as inadequate inclusion criteria and a subsequent high crossover rate.25

The cost-effectiveness of vertebral augmentation has been demonstrated in prior studies.15,26 Conservative management of females with vertebral compression fractures results in incremental costs for the health care system even at 5 years after the VCF.27 From the perspective of elderly patients in the United States, balloon kyphoplasty and vertebroplasty have been found to be cost effective in terms of cost per life year gained compared with nonsurgical management, even for the oldest patients.28 Interestingly, Lange et al16 demonstrated that using German claim data, although the initial cost of the intervention is higher, balloon kyphoplasty is more cost effective than vertebroplasty by providing better pain control and decreasing costs related to oral narcotics in addition to providing survival benefit. Edidin et al28 studied the US Medicare data set and also reported that balloon kyphoplasty was cost effective and perhaps even cost saving when compared with vertebroplasty.

Overall, kyphoplasty has demonstrated better performance than vertebroplasty for patient treatment. When available, kyphoplasty should be preferentially performed. Indeed, adjusted life expectancy is 85% greater for patients who have had vertebral augmentation in comparison to patients treated conservatively, corresponding to a median life expectancy improvement of from 2.2 to 7.3 years.14 Kyphoplasty patients have 115% (P < .001; 95% confidence interval [CI]: 111%-119%) greater life expectancy than patients treated conservatively. On the other hand, vertebroplasty has a 44% (P < .001; 95% CI: 42%-47%) increase compared with conservatively treated patients. Direct comparison between vertebroplasty and kyphoplasty demonstrates a 34% (P < .001; 95% CI: 31%-36%) increase in adjusted life expectancy in favor of the kyphoplasty cohort. Based on these results and on the RAND/UCLA Appropriateness Method, experts agree that balloon kyphoplasty should be preferentially used in almost all circumstances.29


Prior to 2009

Prior to 2009, the literature was favorable toward vertebral augmentation procedures. In fact, a systematic review of the published data prior to 2006 concluded that this procedure was safe and provided pain relief in 87% of patients with vertebroplasty and 92% of patients with kyphoplasty.30 Also, cement leakages were lower in patients treated with kyphoplasty in comparison to vertebroplasty (9% versus 41%). However, the authors of this review suggested that randomized clinical trials were lacking at the time. One year later (in 2007), the VERTOS I study followed with the randomization of 34 patients separated into 2 treatment arms; 1 group was treated with vertebroplasty and the other with conservative therapy. This prospective short-term clinical outcome assessment at 2 weeks demonstrated all QUALEFFO quality-of-life questionnaire and Roland-Morris Disability Questionnaire (RMDQ) scores to be better compared to scores during conservative management.31

Publication of the 2009 New England Journal of Medicine Sham-Controlled Studies

In 2009, Buchbinder et al20 published a multicenter double-blind prospective randomized controlled trial (RCT) comparing patients treated with vertebroplasty with a sham procedure. Thirty-eight patients were treated with vertebroplasty and 40 with a sham procedure. This sham procedure consisted of inserting a 13-gauge needle within the periosteum (arguably a mechanical rhizotomy). Metrics of pain, quality of life, and disability failed to demonstrate a difference between groups at 1 week, 3 months, or 6 months.20 Another multicenter RCT, the Investigational Vertebroplasty Safety and Efficacy Trial, was published concurrently by Kallmes et al,21 evaluating 131 patients with 1 to 3 VCFs. Those patients were divided in the treatment arm (68 vertebroplasties) or a sham group (63 injections of anesthetic on the periosteum, arguably performing medial branch blocks). The primary outcomes were scores on the modified RMDQ and patients’ pain scores. The sham groups of those studies consisted of performing mechanical rhizotomies by inserting a 13-gauge needle through the medial branch of the dorsal rami and through the periosteum20 in addition to blocking this same nerve with anesthetic at the junction of the superior articular process and the transverse process.21

The amount of cement injected is the most important modifiable parameter to ensure treatment success.32 In these 2 New England Journal of Medicine (NEJM) studies, the amount of cement injected was either not reported21 or clearly insufficient (ie, an average of 2.8 cc in the Buchbinder et al20 study). Other studies have detailed more study construct flaws related to patient selection (lack of physical examination performed), low pain intensity score considered as an inclusion criteria (VAS of 3 in the Kallmes et al21 study), and underpowered studies.23,24 Finally, a recent meta-analysis by Anderson et al25 downgraded both the 2009 NEJM studies by Kallmes and Buchbinder from a level I to a level II due to inclusion criteria and subsequent high crossover.

Impact of the Equivocal 2009 NEJM Sham-Controlled Studies

Unfortunately, after the publication of the 2009 NEJM studies, a decrease in the volume of vertebral augmentation reimbursement by insurance companies was noticed. Also, the “mainstream” literature published on the UpToDate website, at, and in the Hayes reports became unfavorable toward vertebral augmentation.

Furthermore, in 2010, the AAOS Clinical Practice Guidelines recommended against vertebroplasty for patients who presented with osteoporotic compression fracture. Also, the guidelines classified the evidence of support of  kyphoplasty as limited.33

These new guidelines, in addition to the disseminated information, resulted in a decrease of the augmentation volume between 2005 and 2014. In fact, vertebral augmentation (kyphoplasty and vertebroplasty) in the US Medicare population utilization was 20% in 2005, peaked at 24% in 2007–2008, and declined to 14% in 2014. In turn, the 5-year period following 2009 was associated with significant elevated mortality risk in VCF patients,2 and not-yet-published data estimated that up to 6814 extra lives may have been lost during this period directly due to the change in treatment patterns.

Studies Published After 2009: Vertebroplasty

In 2010, VERTOS II, an RCT, evaluated 101 patients treated with vertebroplasty versus 101 patients treated with conservative treatment. One month after the intervention, the differences in VAS score between baseline were measured (delta of −5.2 after vertebroplasty and −2.7 after conservative treatment), and the same measurements were performed 1 year after the intervention (delta of −5.7 after vertebroplasty and −3.7 after conservative management). These results highlighted, for the first time after the 2009 NEJM studies, the long-lasting pain relief provided by vertebroplasty in comparison to conservative management.

The VAPOUR trial, published in 2016, is a multicenter, randomized, double-blind, placebo-controlled trial that included 120 patients; 61 were assigned to the vertebroplasty arm and 59 to the placebo arm. Only patients with 1 or 2 osteoporotic vertebral compression fractures of less than 6 weeks’ duration were included in the study. Also, patients had to have numerical rating scale (NRS) back pain greater than or equal to 7 out of 10. Vertebroplasty was performed with an adequate amount of cement (7.5 cc, SD = 2.8 cc). The placebo arm in this study consisted of injecting lidocaine subcutaneously without any periosteal numbing. Patient follow-up was performed for 6 months. The primary outcome was the proportion of patients who had an NRS score below 4 out of 10 at 14 days postintervention; 44% of patients in the vertebroplasty group and 21% in the control group had an NRS pain score below 4 out of 10 at 14 days.34

More recently, the VOPE trial, a trial that evaluated a sham procedure for painful acute osteoporotic vertebral fractures, evaluated 46 patients: 22 in the vertebroplasty arm and 24 in the sham arm. Patients in the sham group received only periosteal lidocaine injection. The results of this study also demonstrate statistically lower VAS scores in the vertebroplasty group at 3 months, and the results are still pending publication.35

The VERTOS II, VAPOUR, and VOPE trials demonstrated the highest level of evidence supporting vertebroplasty.

Studies Published After 2009: Kyphoplasty

For kyphoplasty, there has been 1 RCT (the FREE trial)36 and 1 postmarket trial (the EVOLVE trial)37 clearly demonstrating the benefit of this treatment. Indeed, the FREE trial evaluated 300 patients (149 treated by balloon kyphoplasty and 151 with optimal pain management). In the balloon kyphoplasty group, the mean SF-36 PCS score improved by 7.2 points at 1 month and by 2.0 points in the nonsurgical group. Interestingly, in this study, a correlation between the kyphotic angle and pain reduction was noted.38

The EVOLVE trial, a postmarket trial and the largest vertebral augmentation study to date (354 patients treated with kyphoplasty), was developed to investigate the disability, quality of life, and safety outcomes of a Medicare-eligible population. Patients were evaluated at baseline, 7 days, and 1, 3, 6, and 12 months with 4 coprimary end points: NRS, ODI, SF-36v2 PCS, and EQ-5D. The improvements in these outcomes were statistically significant at every time point.37

Systematic Reviews and Meta-Analyses

A number of systematic reviews and meta-analyses have also been reported in the literature. Papanastassiou et al9 analyzed 27 level 1 and level 2 prospective multiarmed studies with cohorts of at least 20 patients and found that vertebral augmentation provided greater pain relief and fewer subsequent fractures than nonsurgical management in osteoporotic VCFs. Balloon kyphoplasty was also found to be marginally favored over vertebroplasty in disability improvement and significantly favored in quality-of-life improvement. Balloon kyphoplasty also had a lower risk of cement extravasation and resulted in greater kyphosis correction over vertebroplasty.

A meta-analysis of RCTs comparing either vertebroplasty or kyphoplasty to conservative or sham treatment for osteoporotic compression fractures was identified and reviewed by Anderson et al25 Based on 6 studies that were included in the quantitative analysis, cement augmentation was found to result in greater pain relief, functional recovery, and health-related quality of life than nonoperative or sham treatment.

Beall et al37 performed a meta-analysis that built on the work of Papanastassiou et al.9 This review of 25 more recent level 1 and level 2 studies showed that balloon kyphoplasty had significantly better and that vertebroplasty tended to have better pain reduction in terms of VAS compared with nonsurgical management. Balloon kyphoplasty also tended to have better vertebral body height restoration than vertebroplasty.19

The 2013 Kyphoplasty and Vertebroplasty National Institute for Health and Care Excellence Technology Appraisal Guidance

The 2013 National Institute for Health and Care Excellence (NICE) technology appraisal guidance concluded that there was sufficient evidence to state that vertebral augmentation procedures are more effective in reducing pain and restoring vertebral body height than optimal pain management in people with recent, painful, unhealed osteoporotic VCFs.39 These conclusions were made after careful evaluation of the relevant literature at the time, including the 2 2009 NEJM studies.20,21,31,38,40–44 Both vertebroplasty and kyphoplasty were judged to be cost effective at the time. The panel for this report noted a statistically significant mortality benefit for both vertebroplasty and kyphoplasty in comparison to optimal pain management.

Since then, new studies have been published proving the pain relief benefit of these procedures34,37 in addition to new data on the mortality and morbidity2,15–17 that further reinforced the body of knowledge supporting the treatment of clinical VCFs.

Publication and Impact of the VERTOS IV Study

In 2018, the VERTOS IV study evaluated 180 participants randomized to either a vertebroplasty (n = 91) or a sham (n = 89) procedure. The main outcome consisted of the VAS scores at 1 day, 1 week, and 1, 3, 6, and 12 months. Secondary outcome measures were the differences between groups for changes in the quality of life for osteoporosis and RMDQ scores at the 12-month follow-up.22 This study failed to demonstrate statistically significant pain relief in the group treated with vertebroplasty in comparison to the sham procedure.

There was concern that the published VERTOS IV study would have a similar impact as the 2009 NEJM studies. However, the current body of literature strongly favors these procedures (more than 52 level 1 and level 2 studies supporting these therapies and 3 metanalyses), and the medical community seems less impacted in comparison to the 2009 NEJM studies.

The methodology of VERTOS IV has some similarities with the 2009 NEJM studies. First, the sham group represents active treatment. Indeed, the periosteum and medial branch of the dorsal rami were blocked with 1% lidocaine  and 0.25% bupivacaine. Additionally, both the vertebroplasty arm and the sham arm had bilateral mechanical rhizotomy since 2 trocars were positioned with a transpedicular approach. Second, patient selection and follow-up in this study raised some concerns since the physician evaluating the patient prior to the intervention and performing the clinical follow-up was not an interventional pain specialist but rather an internist. Third, the amount of cement injected reported in this study ranged from 1 to 11 cc. It is unlikely that a patient with only 1 cc of cement would have an optimal result.3 Regardless of this very important point, there was no mention of refracture, insufficient cement filling, or adjacent-level fractures in this study, all commonly seen (~15%) in a service with busy vertebral augmentation volume.


Patients who have all of the following criteria may be eligible for vertebral augmentation:

Contraindication to vertebral augmentation:

As suggested by the RAND/UCLA Clinical Care Pathway for the management of VCFs,45 the time since the fracture is now considered less relevant for the treatment of patients.


In general, vertebral augmentation refers to surgical procedures that increase or augment the structural integrity of a fractured/compromised vertebral body. Vertebral augmentation encompasses different techniques, the most common of which are vertebroplasty and kyphoplasty.

However, for the purposes of coding, Current Procedural Terminology (CPT) defines “vertebroplasty” as “the process of injecting material (cement) into the vertebral body to reinforce the structure of the body using image guidance.” Vertebroplasty is reported with CPT codes 22510, 22511, and 22512.

CPT defines “vertebral augmentation” as “the process of cavity creation followed by the injection of the material (cement) under image guidance.” By this definition, kyphoplasty is classified as vertebral augmentation and reported with CPT codes 22513, 22514, and 22515.

When reporting vertebroplasty or vertebral augmentation (kyphoplasty), the code selection is dependent on location and number of segments treated and is inclusive of bone biopsy, when performed, and imaging guidance necessary to perform the procedure:



Vertebral augmentation procedures (vertebroplasty and kyphoplasty) are safe and effective procedures that have been highly studied. The level 1 evidence is overwhelmingly in favor of vertebral augmentation when compared to conservative management. Failure to treat patients with painful VCFs has been associated with an increased mortality and morbidity. ISASS endorses the early treatment of painful VCFs with vertebral augmentation procedures (vertebroplasty and preferentially kyphoplasty). ISASS does not endorse any specific vertebroplasty/ kyphoplasty system. There are numerous systems available that have received 510(K) for use in VCFs. The system used and vertebral levels augmented are the purview of the surgeon.
