Abstract: BACKGROUND: The oblique lateral approach interbody fusion is used more and more clinically. There are more and more biomechanical studies on the oblique lateral approach interbody fusion and internal fixation.
OBJECTIVE: To summarize the research progress of the biomechanics of the oblique lateral approach interbody fusion and internal fixation in recent years so as to provide important reference value for the clinical application of the oblique lateral approach interbody fusion for the treatment of lumbar degenerative diseases.
METHODS: In CNKI, Wanfang, PubMed, and Web of Science databases, “oblique lateral interbody fusion, oblique and anterior lumbar interbody fusion, finite element analysis, biomechanics, lumbar interbody fusion” were selected as the key words, and 45 articles were finally included for review. 
RESULTS AND CONCLUSION: (1) There are few studies on the biomechanics of oblique lateral approach interbody fusion, mainly including the comparison of lumbar interbody fusion with other approaches, stability comparison of different internal fixation methods, postoperative adjacent segmental degeneration, different types of fusion apparatus and so on. (2) The biomechanical stability of the oblique lateral approach is not significantly different from that of the lateral approach, which is better than other approaches. (3) Oblique lateral approach interbody fusion combined with bilateral pedicle screw fixation has the best biomechanical stability, and it is recommended that clinicians apply this technique as the first choice for oblique lateral approach interbody fusion. (4) Comparative studies of biomechanics between oblique lateral approach interbody fusion and anterior approach interbody fusion are insufficient, and there are few clinical outcomes comparisons, and further research is needed.
