分析肩肘外科领域国家自然科学基金和国家重点研发计划布局，回顾肩肘外科领域研究的发展情况和趋势，为该领域未来研究方向提供参考。

从国家自然科学基金委员会数据库中筛选医学科学部肩肘外科领域所有立项项目，分析数量与构成、资助金额、立项数量与资助金额的机构分布情况及关键词分布。从国家重点研发计划数据库中筛选所有肩肘外科领域项目指南。

1993年1月至2022年10月肩肘外科领域国家自然科学基金共立项项目53项，以面上项目和青年科学基金项目为主。项目的机构分布不均衡，存在聚集趋势。项目负责人以肩肘外科相关临床医师为主。通过关键词共现聚类分析，目前肩肘外科领域的研究热点为肩袖损伤修复的机制研究，肘关节、肱骨骨折等生物力学研究，促进肩袖腱骨愈合的不同物质及作用机制研究，肩袖损伤脂肪浸润相关机制研究和冷冻肩的炎症纤维化机制研究。肩肘外科领域在国家重点研发计划中未见单独立项项目。

我国的肩肘外科研究整体尚处于初级阶段，建议从顶层设计和宏观布局，加强肩肘外科领域研究支持力度，以临床需求为导向、依靠学科交叉推进肩肘外科研究不断进步。

Shoulder and elbow surgery in China started relatively late. In recent years, with the continuous progress of medicine and related disciplines, scientific research has played an essential role in promoting the development of shoulder and elbow surgery. There is a lack of relevant research on the layout of the national scientific research project in the shoulder and elbow surgery field in China.

To analyze the layout of NSFC and the National Key R&D Program in the field of shoulder and elbow surgery, to summarize the development and trend of research in the field, and to provide a reference for future research directions.

All approved projects in the field of shoulder and elbow surgery were selected from the NSFC database. The number, composition, funding amount, institutional distribution, and keyword distribution were analyzed. All project guidelines in the shoulder and elbow surgery field were selected from the National Key R&D Program database.

From January 1993 to October 2022, 53 shoulder and elbow surgery projects were supported by the NSFC, mainly including general and youth science fund projects. The institutional distribution of the project is uneven, with a trend of aggregation. The project leader was mainly clinicians related to shoulder and elbow surgery. By means of keyword collinear cluster analysis, it is analyzed that the current research hotspots in the field of shoulder and elbow surgery mainly focus on the research on the mechanism of rotator cuff injury repair, the biomechanical research on the elbow joint and humeral fracture, the research on different substances and mechanisms of action that promote the healing of rotator cuff tendon-bone, the research on the mechanism related to fat infiltration of rotator cuff injury, and the research on the mechanism of inflammation and fibrosis of frozen shoulder. There is no independent shoulder and elbow surgery project in the National Key R&D Program.

The overall research on shoulder and elbow surgery in China is still at the initial stage. It is suggested to strengthen the research support in the shoulder and elbow surgery field from the top design and macro layout. Shoulder and elbow surgery research should be guided by clinical needs and promoted by interdisciplinary research in the future.
