Protocol for systematic review and meta-analysis on the efficacy and safety of acupuncture for residual low back pain after percutaneous kyphoplasty in patients with osteoporotic vertebral compression fracture

Abstract

IntroductionOsteoporotic vertebral compression fracture (OVCF) is a common complication in elderly patients with osteoporosis. Despite undergoing percutaneous kyphoplasty (PKP) treatment, a significant percentage of OVCF patients (1.8% to 31.9%) continue to experience residual low back pain. While acupuncture has shown promise in relieving this pain, there is currently no systematic review on its efficacy specifically for residual low back pain after PKP in OVCF patients. This project aims to evaluate the effectiveness and safety of acupuncture as a treatment for this condition.Methods and analysisA comprehensive search will be conducted, including manual and electronic searches of literature published. Various databases such as MEDLINE, PubMed, EMBASE, Web of Science, Cochrane Library, International Clinical Trial Registration Platform, China National Knowledge Network, China Biomedical Literature Database, China Scientific Journal Database and Wan-fang Database will be explored. Additional sources like bibliographies and meeting minutes will also be searched. All randomised controlled clinical trials related to acupuncture for treating residual low back pain after PKP in OVCF patients will be included. Two researchers will independently perform study selection, data extraction and quality assessment. The primary outcome measure will be pain relief assessed using a visual analogue scale (VAS) or other validated scales. Secondary outcomes include effectiveness, Oswestry dysfunction index (ODI), quality of life questionnaire (QUALEFFO-41), follow-up relapse rate and adverse events. If feasible, a meta-analysis using RevMan V.5.3 software will be conducted. Otherwise, descriptive or subgroup analyses will be performed. Database searches will commence after the publication of this agreement, with an estimated commencement date of 1 August 2024.Ethics and disseminationEthical approval is not required since this review does not involve individual patient data. The findings will be disseminated through peer-reviewed journals or relevant conferences.PROSPERO registration numberCRD42023478838.
