Abstract Background Little is known about the biomechanical performance of different internal fixations in oblique lumbar interbody fusion (OLIF). Here. finite element (FE) analysis was used to describe the biomechanics of various internal fixations and compare and explore the stability of each fixation. Methods CT scans of a patient with lumbar degenerative disease were performed. https://www.poolsproductscanadas.shop/product-category/omnilogic-parts/
