Background: Osteoporotic vertebral compression fractures (OVCFs) are the most common osteoporotic fractures. Pain is the main symptom. Percutaneous vertebroplasty (PVP) is a therapeutic procedure performed to reduce pain in vertebral compression fractures. Numerous case series and several small, non-blinded, non-randomized controlled studies have suggested that vertebroplasty is an effective means of relieving pain from osteoporotic fractures. However, a recent pooled analysis from 2 multicenter randomized controlled trials concluded that the improvement in pain afforded by PVP was similar to placebo. Objective: To compare the amount of pain reduction measured using the visual analog scale when OVCF is treated with vertebroplasty or conservatively, and assess the clinical utility of PVP. Design: A meta-analysis and systematic review of randomized controlled trials was performed comparing pain reduction following vertebroplasty and conservative treatment. Limitations: There were few data sources from which to extract abstracted data or published studies. There were only 5 randomized controlled trials that met our criteria. The conservative treatments used as comparators in these trials were different. Methods: A search of MEDLINE from January 1980 to July 2012 using PubMed, the Cochrane Database of Systematic Reviews and Controlled Trials, CINAHL, and EMBASE. Relevant reports were examined by 2 independent reviewers and the references from these reports were searched for additional trials, using the criteria established in the QUOROM statement. Results: Pooled results from 5 randomized controlled trials are shown. There was no difference in pain relief in the PVP group at 2 weeks and one month when compared with the conservatively managed group. Pain relief in the PVP group was greater than that of the conservative group at 3 months, 6 months, and 12 months. However, after subgroup analysis, pain scores were similar between the PVP group and the sham injection group from 2 weeks to 6 months. Compared with non-operative therapy, PVP reduced pain at all times studied. Conclusion: PVP has some value for relieving pain; however, the possibility of a placebo effect should be considered. PVP has gained acceptance as a complementary treatment when conservative management has failed before its benefits have been fully understood. More large scale, double blinded, controlled trials are necessary in order to quantify the pain relief afforded by PVP more precisely.

Long Term Follow Up

Background: Kyphoplasty reduces the pain caused by osteoporotic vertebral compression fracture (OVCF). Although the procedure is typically carried out using a bilateral approach, it is now increasingly performed using a unilateral approach because of the concern for longterm adverse effects. However, little evidence is available to demonstrate superior safety of the unilateral approach. Objective: The purpose of this study was to compare the short- and long-term safety and efficacy of unilateral vs. bilateral kyphoplasty. Study Design: A systematic review and meta-analysis of randomized controlled trials. Settings: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and abstracts published in the related orthopedic journals were systematically searched up to September 2012, using “unilateral kyphoplasty” and “osteoporotic vertebral compression fractures” as key words. Methods: Two investigators independently searched and identified relevant reports and abstracts using the PRISMA statement criteria. Relevant studies cited by the identified papers were also included. The level of evidence was classified as good, fair, and limited (or poor) based on the quality of evidence developed by the U.S. Preventive Services Task Force (USPSTF). Results: Four randomized controlled trials (RCTs) of 159 cases were enrolled. The methodological quality of the articles was determined as moderate. We did not find any significant difference between unilateral and bilateral kyphoplasty on pain relief, in either short-term or long-term follow-up (P = 0.65 and P = 0.69, respectively). The rate of adjacent vertebral fracture was not statistically different with a P value of 0.88 and 95% CI (confidence intervals) of 0.25-3.26. Cement leakage was comparable between unilateral and bilateral kyphoplasty (P = 0.56, 95% CI = 0.46-4.26). The loss of vertebral height in long-term follow-up was not different (P = 0.10, 95% CI = -0.39-4.54). Operation time and cement dosage were considerably less for unilateral kyphoplasty (P < 0.01 and P < 0.05, respectively). Limitations: Only 4 RCTs and 159 patients were included in this systematic review. Publication bias also existed among the studies included. Conclusions: Both unilateral and bilateral kyphoplasty are effective in alleviating the back pain caused by OVCF. Two approaches have the same degree of safety. More RCTs are needed to examine the efficacy and adverse reactions of the 2 approaches.

Background: An increasing number of studies have been conducted to apply unilateral balloon kyphoplasty in the treatment of ostroporotic vertebral compression fractures (OVCFs). However, the efficacy and safety of unilateral kyphoplasty and whether a unilateral or a bilateral approach is superior is controversial. Objectives: The purpose of this study was to evaluate the role of unilateral balloon kyphoplasty and use meta-analysis to compare the efficacy and safety of unilateral and bilateral kyphoplasty in patients with OVCFs. Study Design: A systematic literature search was conducted from 1970 to April 2017 using Medline database and the Cochrane Central Register of Controlled Trials. Articles were limited to those published in English. Randomized controlled trials and nonrandomized comparative studies were also included. Setting: The following search terms were used: “osteoporotic vertebral compression fractures,” or “OVCF,” and “unilateral kyphoplasty,” or “unipedicular approach,” or “single balloon kyphoplasty,” or “one balloon kyphoplasty.” A comprehensive search of reference lists of retrieved articles and previous published reviews was also performed to ensure inclusion of all possible studies. Methods: All potential articles were independently reviewed by 2 investigators for inclusion into the final analysis. MINORS score was used for nonrandomized studies, and Detsky quality index was applied for prospective randomized controlled trials. Systematic review and meta-analysis was performed for the included studies. Results: After unilateral balloon kyphoplasty the mean postoperative visual analog score (VAS) was from 1.74 to 4.77, mean postoperative kyphotic angle was from 5.9º to 11.22º, and complications involving cement leaks was from 6.8 to 21.9% or adjacent level fractures was from 0 to 5.6%). Unilateral kyphoplasty had significantly lower operative time, and less bone cement volume; however, the postoperative VAS, Oswestry Disability Index (ODI), vertebral height restoration rate, and cement leakage and adjacent vertebral fracture rate, were similar to bilateral kyphoplasty. Limitations: Only 6 randomized controlled trials and 3 retrospective comparative studies were selected for analysis. Heterogeneity was detected among the studies when we pooled the outcomes. Conclusions: Based on the available evidence, the clinical and radiological results of unilateral balloon kyphoplasty were as good as those of bilateral balloon kyphoplasty for the treatment of OVCFs. And unilateral kyphoplasty had advantages in terms of operation time, radiation exposure, and cost.
