- W2356620904 abstract "ObjectiveTo evaluate the effect of lumbar fusion in different sagittal alignments on the upper adjacent intradiscal pressure. Methods Lumbar spine (L_ 3-S_ 2) specimens from ten fresh human cadavers were used. After intact test, three different sagittal fixation angles at L_ 4,5 were randomly simulated with pedicle screws in each specimen: ① in situ (lordosis 10 degrees). ② kyphotic (kyphosis 5 degrees), and ③ hyperlordotic (lordosis 25 degrees). Biomechanical test was performed under 6 N·m flexion and extension loading modes. Intradiscal pressures at L_ 3,4 were measured and compared. ResultsIn flexion test, three fixation methods resulted in higher intradiscal pressure at L_ 3,4 than the intact spine. Importantly, intradiscal pressure of the upper segment in kyphotic fixation group was the highest. In extension test, L_ 3,4 intradiscal pressure of kyphotic group was significantly higher than the other fixation groups;But no statistical difference was detected among the intact, in situ, and hyperlordotic groups. ConclusionSpinal fixation can increase the stress at the adjacent segment, and lumbar malalignment fixations may further worsen this biomechanical condition. For lumbar reconstruction, obtaining the normal lumbar alignment is required." @default.
