Abstract: BACKGROUND: Lateral lumbar interbody fusion has become more and more widely used in clinic. Biomechanical research on lateral lumbar interbody fusion is increasing.
OBJECTIVE: To summarize the biomechanical research progress of lateral lumbar interbody fusion and expect to provide some guidance for clinicians to use lateral lumbar interbody fusion in the treatment of lumbar spine diseases. 
METHODS: CNKI, Wanfang, and PubMed databases were retrieved. The Chinese key words were “lateral lumbar interbody fusion, extreme lateral interbody fusion, direct lateral interbody fusion, finite element, biomechanics”. The English key words were “lateral lumbar interbody fusion, direct lateral interbody fusion, extreme lateral interbody fusion, oblique lumbar interbody fusion, finite element, biomechanics”. Finally, 32 articles were included for review.
RESULTS AND CONCLUSION: (1) Current biomechanical research on lateral lumbar interbody fusion mainly includes comparison between lateral lumbar interbody fusion and anterior-posterior surgery, stability of different internal fixation methods of lateral lumbar interbody fusion, incidence of adjacent vertebral disease after lateral lumbar interbody fusion, and research on new internal fixations of lateral lumbar interbody fusion. (2) The biomechanical stability of lateral lumbar interbody fusion is similar to that of anterior lumbar interbody fusion and posterior lumbar interbody fusion, and is better than that of transforaminal lumbar interbody fusion. Clinicians can give priority to lateral lumbar interbody fusion when choosing the operation methods. (3) Bilateral pedicle screw rods and lateral plate and spinous plate joint fixation has the best biomechanical performance. It is recommended that clinicians use this two internal fixation methods as the first choice. (4) Although there are many biomechanical studies on lateral lumbar interbody fusion, there are few basic biomechanical studies between extreme lateral interbody fusion and oblique lateral interbody fusion, because extreme lateral interbody fusion is through the transpsoas muscle approach, and oblique lateral interbody fusion is through the anterior approach of the psoas major muscle. Whether the psoas major has an effect on the biomechanical stability after lateral lumbar interbody fusion deserves to be further studied.
