The effectiveness and safety of cervus and cucumis polypeptide injection in promoting fracture healing after bone fracture surgeries: Protocol for a systematic review and meta-analysis

BACKGROUND: Bone fractures are a common occurrence, and, according to clinical investigations, approximately 5% to 10% of patients with fractures will suffer from delayed healing or even non-healing. The high efficacy of traditional Chinese medicine in promoting fracture healing has been fully verified over a long history of diagnosis and treatment. Traditional Chinese medicine has a long history of applying Chinese herbs to treat fractures. Cervus and cucumis polypeptide injection has been widely used to promote fracture healing after fracture surgery in clinic, but its efficacy and safety are controversial. For the above reasons, the purpose of this study is to systematically evaluate the efficacy and safety of cervus and cucumis polypeptide injection in promoting fracture healing after bone fracture surgeries and to provide a theoretical basis for the selection of appropriate treatment measures for delayed healing of patients with fractures. METHODS: A total of 8 databases were searched, including the non-Chinese-language databases PubMed, The Cochrane Library, Web of Science, and Embase and the Chinese databases Chongqing VIP Chinese Journal Service Platform (VIP), Wanfang Data Knowledge Service Platform (Wanfang Data), SinoMed and Chinese National Knowledge Infrastructure (CNKI). The databases were queried for publicly released randomized controlled trials of the effectiveness and safety of Cervus and Cucumis polypeptide injection for fracture healing after surgical treatment, and no language restrictions were imposed. The software Review Manager 5.3 was used to evaluate the quality of the selected documents, and Stata 12.0 software was used for statistical analysis. RESULTS: This review will be to assess the efficacy and safety of cervus and cucumis polypeptide injection in promoting fracture healing after bone fracture surgeries. CONCLUSION: Our study will use systematic evaluation to objectively evaluate the efficacy and safety of cervus and cucumis polypeptide injection in promoting fracture healing after fracture surgery. It will provide theoretical basis for guiding clinical practice and benefit more patients. ETHICS AND DISSEMINATION: This study is a systematic review that does not require ethical approval and meets the requirements of protocol for a systematic review and meta-analysis. At the same time, this study does not involve the recruitment of patients. All data are from published academic papers. PROTOCOL AND REGISTRATION: A protocol had been registered for this systematic review and meta-analysis in PROSPERO. (registration number: CRD42019120965).
