摘要

Background

Adolescent idiopathic scoliosis (AIS) is a complex three-dimensional spinal deformity, frequently requiring fusion surgery. An optimal fusion surgical strategy can not only achieve effective correction but also reduce the incidence of postoperative complications. Recently, several researchers have refined and expanded AIS fusion surgical strategies based on the Lenke classification system, which is the current international standard for AIS. Therefore, this study aims to review the advances in fusion level selection and surgical approaches for AIS based on this classification.

Methods

Databases such as PubMed, Embase, Web of Science, Scopus, Cochrane Database, China National Knowledge Infrastructure, Wanfang Database, and China Biomedical Literature Database were queried for articles using the keywords “adolescent idiopathic scoliosis”, “fusion surgery”, “Lenke classification system”, “Lenke 1”, “Lenke 2”, “Lenke 3”, “Lenke 4”, “Lenke 5” and “Lenke 6”.

Results

Over the past decade, fusion surgical guidelines based on the Lenke classification have been refined, with new strategies emerging. We summarize the latest AIS fusion surgical strategies with recent research results. However, the fusion strategy based on the Lenke classification system has undergone no revolutionary changes. The selection of surgical designs for certain subtypes remains controversial.

Conclusion

The fusion surgical strategy based on the Lenke classification system remains the standard for AIS surgical treatment. With the advancement of surgical technologies, further optimization of surgical strategies and the development of three-dimensional classification systems are potential future directions.
