The Efficacy and Safety of Acupuncture for Treating Osteoporotic Vertebral Compression Fracture- (OVCF-) Induced Pain: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

Abstract

Background. Osteoporotic vertebral compression fractures (OVCFs) are common health issues in the elderly that cause chronic pain in over one-third of patients. This study was sought to evaluate the efficacy and safety of acupuncture for alleviating pain caused by OVCFs. Methods. We performed a search of 8 electronic databases for publications from the inception to 30th March 2021. Eligible studies were randomized clinical trials (RCTs) that evaluated the effect of acupuncture for the treatment of OVCFs. Two investigators evaluated literature quality and extracted data independently. RevMan V.5.4.1 was used for data analyses, with pooled risk estimates presented as mean difference (MD) or relative risk (RR) along with corresponding 95% confidence intervals (CIs), as appropriate. Results. Fourteen RCTs involving 1,130 patients were included in this meta-analysis. Compared with the control group, acupuncture showed a greater benefit on pain reduction caused by OVCFs (1 week: MD = −1.26, 95% CI: (−1.82,−0.70); 1 month: MD = −1.63, 95% CI: (−1.82,−1.43); 6 months: MD = −1.13, 95% CI: (−1.55, −0.70)). Acupuncture treatment was also associated with fewer adverse events, lower ODI index, and higher bone density than the control group (safety: (RR: 0.30, 95% CI: 0.12–0.75); ODI: MD = −3.19, 95% CI: (−5.20, −1.19); bone density: MD = 0.15, 95% CI: (0.05, 0.26)). The GRADE quality of these results was assessed as low or very low. Conclusions. Compared with the control treatment, acupuncture was more effective and safer in relieving the pain caused by OVCF and made a greater improvement on patient’s ODI score and bone density. Given the low level of our study evidence, future high-quality studies are needed to verify our study findings.

The Efficacy and Safety of Zhengqing Fengtongning for Knee Osteoarthritis: A Systematic Review and Meta-Analysis of Randomized Clinical Trials

“…A bias risk assessment was conducted by two reviewers (Zeling Huang and Xiao Mao) based on the bias risk assessment tool recommended in the Cochrane manual [ 39 , 40 ]. The details that were assessed were as follows: (1) random sequence generation; (2) allocation concealment; (3) blinding of participants and personnel; (4) blinding of outcome assessment; (5) incomplete outcome data; (6) selective reporting; and (7) others.…”

The efficacy of electroacupuncture in the treatment of osteoporotic thoracolumbar compressionfractures in menopausal women:a study protocol for a prospective, two-arm, single-center randomized controlled trial.

“…Electroacupuncture treatment [31] is administered once a day for the first four weeks and once every two days for the last four weeks. Medication will be administered on time according to the medication instructions.…”

“…The spine is the slowest area for fracture healing, and there are clinical reports that for the vast majority of patients, OVCF is the beginning of severe long-term pain and disabling disease [19], it has been reported that pain in cone fragility fractures is largely self-relieving only 13 weeks after the fracture [20]. In addition, there are few studies of EA as a separate treatment modality for mild OVCF, the quality of studies on acupuncture for compression fracture healing are low and the number are few [21]. To further explore the effect of electroacupuncture in OVCF, more high quality, large sample randomised controlled trials(RCT) should be conducted.…”
