Efficacy of extracorporeal shock wave combined spinal core decompression for the treatment of patients with femoral head necrosis: A protocol for systematic review and meta-analysis

Previous studies have reported that extracorporeal shock wave (EPSW) combined spinal core decompression (SCD) has been used for the treatment of patients with femoral head necrosis (FHN) effectively. However, their results are still inconsistent. Therefore, this study will systematically assess the efficacy and safety of EPSW and SCD for the treatment of patients with FHN. This study will systematically search the following databases from inception through March 1, 2020: MEDLINE, Web of Science, Scopus, EMBASE, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, and China National Knowledge Infrastructure. All searches will be performed without language and publication date restrictions. This study will only include randomized controlled trials investigating the efficacy and safety of EPSW and SCD for the treatment of patients with FHN. Two authors will independently assess all literatures, extract data, and appraise risk of bias. Any confusion between 2 authors will be cleared up by a third author through discussion. RevMan 5.3 software will be utilized to analyze the data and to perform a meta-analysis if necessary. This study will summarize up-to-date evidence and provide a detailed summary related to the efficacy and safety of EPSW and SCD for the treatment of patients with FHN. This study may provide helpful evidence to determine whether or not EPSW combined SCD is effective and safety for the treatment of patients with FHN. INPLASY202040092.
