Extracorporeal shock wave therapy for stenotic tenosynovitis of styloid process of radius: A protocol for systematic review and meta-analysis

： Background: Stenosing tenosynovitis of styloid process of radius is a chronic non-specific inflammatory disease, which is mainly characterized by local pain and limitation of wrist movement. The pathogenesis of the disease is complex and not yet clear, so there is no better treatment strategy. At present, clinical treatment includes two kinds of treatment: operation and conservative treatment. Studies have shown that extracorporeal shock wave therapy (ESWT), as a new non-operative physiotherapy in the field of orthopaedics, has a significant effect on the disease. This article will make a comprehensive and objective discussion on the clinical efficacy of extracorporeal shock wave in the treatment of stenotic tenosynovitis of radial process. Methods：Chinese database (China knowledge net, VIP database, Wanfang database and Chinese biomedical database) and English database (PubMed, Embase, the Cochrane Library, Web of Science) will be searched. All randomized controlled trials about extracorporeal shock wave treatment of stenosing tenosynovitis of radial styloid process at home and abroad will be collected for Meta-analysis. The retrieval time limit is from the time of database establishment to November 2020. Two authors will independently conduct literature screening, data extraction and included literature evaluation. The bias risk assessment tool provided by Cochrane Collaboration Network will be used for quality evaluation. Revman5.3 software will be used for meta-analysis of the included literature. Results：In this study, the included literature will be systematically analyzed, and the results will show that extracorporeal shock wave therapy (ESWT) have advantages. ESWT can effectively relieve the pain symptoms of stenosing tenosynovitis of styloid process of radius and restore the function of wrist joint. It has a significant effect on stenotic tenosynovitis of styloid process of radius. Conclusion：This study will provide evidence-based medical evidence for the clinical efficacy of extracorporeal shock wave in the treatment of stenosing tenosynovitis of radial styloid process.
