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.
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. Surgical parameters, subjective quality of life assessments and objective functional timed up and go and radiographical assessments were collected. At 24 months, the change in index fracture kyphotic angulation was statistically significantly improved in the kyphoplasty group average 3. The most common adverse events temporally related to surgery i. Several other adverse events were possibly related to patient positioning in the operating room.
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.
Clinical vertebral fractures affect an estimated 1. Balloon kyphoplasty BKP is a percutaneous surgical option that aims to reduce pain and disability and correct vertebral body deformity using orthopedic balloons.
Within the current literature, there are well over unique cohorts of at least 10 patients or more with vertebral compression fracture due to osteoporosis or cancer treated with kyphoplasty or vertebroplasty. Importantly, within the current literature, several studies have demonstrated that kyphoplasty and vertebroplasty provide better clinical outcomes to NSM in randomized controlled studies 2—6 ; however, surgical parameters and radiographical outcomes have either been limited or not collected or reported.
We recently reported 1- and 2-year quality of life QOL outcomes of the fracture reduction evaluation FREE study, a multinational, randomized controlled trial. The protocol and consent forms were approved by local ethics committees. BKP was performed using introducer tools, inflatable bone tamps, and polymethylmethacrylate bone cement, and delivery devices manufactured by Medtronic Spine LLC, Sunnyvale, CA , using a percutaneous, bilateral, transpedicular, or extrapedicular approach that has been described in detail elsewhere.
NSM consisted of analgesics, bed rest, bracing, physiotherapy, rehabilitation programs, and walking aids according to standard practices of participating physicians and hospitals; patients who underwent BKP also received these therapies as required.
All patients were referred for treatment with calcium and vitamin D supplements and antiresorptive or anabolic agents; please refer to previous reports for results of these treatment modalities. Methods for pain, function, and QOL outcome measures have been described previously.
Standing lateral spine radiographs were taken at baseline, postoperatively BKP subjects , 3, 12, and 24 months and read centrally BioClinica Inc, Newtown, PA ; 2 radiologists independently used semiquantitative grading for fracture determination 10 and a single reader made quantitative morphometric measurements from endplate to endplate at the posterior, anterior, and midpoint of the vertebral body. For vertebral body height, a fractured-to-nonfractured ratio was calculated.
The prefracture height was estimated by averaging the measurements for the adjacent superior and inferior nonfractured vertebral bodies up to 4 levels away; otherwise the index fracture was considered nonevaluable.
These analyses included randomization stratification factors and baseline as covariates. Angulation and vertebral height data were assessed for normality using Shapiro-Wilk test statistics and P values for nonparametric tests were used as a result. P values for within group change from baseline are based on the signed-rank test and within group change across all time points was assessed using the Friedman test; comparison between groups at each time point is based on the Mann-Whitney test.
No adjustments were made for multiple tests and a P value of 0. For regression analyses, improvement in PCS at 3 mo was used as the dependent variable with the following explanatory variables treatment, baseline steroid use, baseline RMDQ, VAS and limited activity days, sex, spine T-score, age, baseline bisphosphonate use, estimated fracture age, number of prevalent fractures, and change in kyphotic angulation ; baseline EQ-5D, hip T-score and etiology were not included in the model due to high autocorrelation with RMDQ, spine T-score and baseline steroid use, respectively.
The 2 groups were comparable at baseline for demographic variables Table 1. For the patients who received BKP, on average, kyphoplasty was performed 7 days range, 0—41 following randomization. Most patients were treated using general anesthesia Cement leakage, assessed by physicians intraoperatively, occurred in 51 of Hospitalization duration was a median of 4. The kyphoplasty group had 5. Also, patients assigned to kyphoplasty had statistically significant improvements in EQ-5D, more back pain relief, less Roland-Morris back disability, and were more satisfied on a point Likert scale Table 3.
The difference in categorical change from baseline between study groups was statistically significant from 1 to 6 months Table 4. For both index and prevalent fractures, the majority of fractures occur in the transition zone at T12 and L1.
Study patients had many more prevalent fractures compared with those identified clinically Figure 1. The postoperative mean change from baseline showed an average improvement of 3. At 24 months, the change from baseline in index fracture kyphotic angulation was statistically significantly improved in the kyphoplasty group with a correction of 3.
Index vertebral body kyphotic angulation correction and height restoration. Group comparison P values are shown for each time point. Compared with angulation data, there were less evaluable data for assessing vertebral body height Figure 2 ; only of the treated vertebrae were evaluable.
In this study the mean baseline anterior vertebral height was In the BKP group, with a mean postoperative anterior gain of At 24 months, anterior and medial measurements in kyphoplasty were statistically significantly improved 6. To assess the possible link between BKP kyphotic angulation correction and clinical outcome, we performed a correlation of the change-from-baseline in PCS and kyphotic angulation at 3 months, the first time point in which both of the clinical and radiographical parameters were assessed, seem to be at steady state and maximize evaluable data.
Because patients could have multiple fractures, kyphotic angulation correction for multiple fractures were summed for individual patients. To further evaluate this, patients in the bottom and top quarts of kyphotic angulation improvement were compared with regard to PCS improvement Table 5.
Similarly, patients with highest PCS improvement had better kyphosis correction 5. In similar analyses with the control NSM group, no correlation was found and there were no statistically significant differences in the upper and lower quarts for PCS or kyphotic angulation data not shown. The figure shows the kyphotic angulation improvement for the upper and lower quarts for each clinical outcome measure. For each assessment, Shapiro-Wilk normality test was conducted.
To evaluate what variables are the most predictive of PCS QOL, we performed a multivariate backward elimination regression model.
Table 6 shows the results of the final model with remaining variables and adjusted P values. It is clear that the number of baseline prevalent fractures and treatment group are the most predictive variables overall better outcomes in the BKP group and better outcomes in patients with fewer prevalent fractures at baseline and fracture age to a lesser degree younger fractures correlating to better outcomes. Similarly, within each treatment group, the number of prevalent fractures was most predictive.
To assess safety events temporally related to surgery, we report all AEs occurring within the first 30 days Table 7. Four hematomas occurred in the BKP group; 2 were considered procedure-related and 2 device-related 1 of these was a serious AE.
Two nonserious AEs were related to intubation, hypersensitivity to atracurium besilate and damage to dental bridge Table 7 ; the latter was the only AE noted to have occurred on the operative case report form. To provide a context of this research, in September , a thorough evaluation of the kyphoplasty literature was conducted using PubMed. For clinical studies consisting of at least 10 patients with vertebral compression fracture due to osteoporosis or cancer treated with kyphoplasty, we found what seemed to be unique cohorts and a total of patients treated with kyphoplasty, most reporting similar improvements in pain, function, and QOL.
Within the current literature we have found several randomized clinical trials comparing either kyphoplasty or vertebroplasty to nonsurgical management NSM , 2—4 , 6 , 31—34 and several reports that compare the cost-effectiveness of these procedures compared with NSM.
However, it is important to note in this study, for most criteria, maximal benefit, and stabilization for each group occurs between 3 and 12 months, and we have demonstrated better pain and EQ-5D QOL outcomes compared with NSM throughout 2 years, 2 an outcome not consistent with placebo effects.
To date none of the major RCTs for kyphoplasty or vertebroplasty have described detailed radiographical outcomes. Therefore, we have extended our previous results to describe the surgical parameters, vertebral body kyphosis correction and height restoration, the objective TUG test results, and intraoperative safety and analyses exploring the link between vertebral body anatomy correction and QOL.
The correction was, not surprisingly, better in the BKP group compared with the NSM group at all time points through 24 months. The difference between the treatment groups met the 0. For RMDQ, using 2 to 3 points as the MCID, 47 results were statistically and clinically significant through 12 months and marginally statistically significant at 24 months. A few studies have demonstrated a possible connection between angulation and pulmonary function, 49 , 50 but few studies have demonstrated a clinical benefit of height restoration.
To our knowledge, no MCID has been established for kyphosis correction and the clinical relevance of the average 2.
Moreover, patients with the highest amount of kyphosis correction had approximately 6 points more PCS improvement at 3 months; putting this in a clinical perspective, 3. Fracture mobility, fracture age, patient positioning bolstering , IBT use and possibly anesthesia type are important parameters that may influence fracture reduction. However, our data also suggest, to a lesser extent, that treating physicians should also consider all parameters in achieving maximal vertebral anatomy correction when performing vertebral augmentation which is in line with orthopedic principles.
We previously reported and discussed the long-term serious AEs and those related to device or procedure 1 patient with UTI and subsequent spondylitis, 1 patient with a hematoma and 1 with anterior cement migration. Recently, there is a trend toward more local anesthesia use, likely due to more interventional radiologists performing BKP, but this is a challenge in elderly patients with scoliosis and facet arthritis.
Similarly, a few of the UTIs, common in the elderly, were exacerbated by catheterization. There were 9 nonserious AEs possibly related to prone positioning in the operating room; this safety data suggest the need for extreme care in preparing these elderly patients for surgery.
A few new fractures were considered possibly related to bone cement; however, there was no statistically significant difference in the number of patients with new fractures or adjacent fractures. A few such patients in our study were regarded as asymptomatic because no intraoperative AEs were noted by investigators and in reviewing all AEs throughout the study for these patients, only a new fracture AE was considered cement related.
Thus, we have found, similar to those of several meta-analyses, 16 , 18 , 55 that such leakages occur least often e. It is thought that creation of a void with the IBT with a known volume for cement fill and the compaction of cancellous bone along with use of radiopaque, viscous, cement and fluoroscopy use during cementation can help reduce such leakages.
This is the largest randomized trial of surgical treatment for vertebral fractures, with relatively high rates of follow-up for 2 years and assessment of multiple clinical and radiographical endpoints compared with standard practice; however, our study has several limitations. Knowledge of treatment assignment may have influenced patient responses or radiologist assessments.
The study, powered to detect differences between groups in SF PCS at 1 month, may not be adequately powered to detect differences in other radiographical, clinical, or safety outcomes. The radiographical data collection and therefore, the analysis, had several limitations.
Due to the multicenter nature of the trial, the quality of the films and use of standard markers to control magnification error was variable despite the use of a detailed radiographical protocol and training. Therefore, for height restoration, we had to rely on normal adjacent vertebrae to estimate height.
We used standard thoracic and lumbar films to capture all vertebral bodies from T5—L5; because most fractures occur in the transition zone, these areas are often on the extreme ends of the films where parallax is maximized and the next normal vertebrae may not be captured on the same film. Adjacent prevalent fractures Figure 1 also diminished these evaluations. As a result, compared with vertebral body height restoration data, there was more evaluable radiographical data for kyphotic angulation of index fractures; this is because this measurement does not necessitate controlling for magnification error and does not depend on including normal adjacent vertebrae.
Finally, the analyses of clinical outcomes and radiographical results kyphotic angulation correction suggest a link but were exploratory in nature and less predictive than other variables such as baseline prevalent fracture; more studies are required where the study design is appropriately focused to confirm this hypothesis. We conclude that, compared with NSM, BKP rapidly reduces pain and improves function, disability, and QOL during the course of 2 years and the reduction in pain, EQ-5D QOL, patient satisfaction, and kyphotic angulation remain statistically significant at all time points.
Perioperative complications could be minimized with more care in patient positioning. The authors and study investigators are indebted to the patients, who consented to participate in the FREE trial, and to all participating staff at the investigational centers.
