Abstract: OBJECTIVE： To analyze the research hot-spots and treatment trend of the minimally invasive treatment method of lumbar disc herniation in China based on visualized analysis. METHODS： The China National Knowledge Network (CNKI) and Web of Science database (WOS) were searched for minimally invasive treatment of lumbar disc herniation and related terms. CiteSpace and VOSviewer software were used to make correlation analysis of the relevant literature collected from January 2013 to December 2023，and the data were analyzed from high-frequency keywords，highlights to the trend of times. RESULTS： A total of 1 065 literature from CNKI and 602 literature from Web of Science (WOS) were included. After visual analysis，there were ten clusters obtained from the CNKI database and nine clusters obtained from the WOS database respectively，including LDH，PELD etc.，and risk factors，LDH，spinal stenosis etc. CONCLUSION： Research in the CNKI database mainly focused on treatment outcome，transforaminal approach，lumbar function，pain，complications，auxiliary therapy，complications，surgical approach，scientific research methods，etc. In the WOS database，research mainly focused on decompression，treatment outcome，complication，transforaminal approach，back pain，spine，learning curve，and risk factor，etc. In the last two years，the research of CNKI mainly focused on the key words of pain and PELD，and the research of WOS mainly focused on the key words of complications and recurrence rates. At present，the research hot-spots have been partially overlapping，and different among the Chinese and foreign scholars.
