STUDY DESIGN An in vitro biomechanical study of adjacent segment motion (at L3-L4 and L5-S1) after a simulated lumbar interbody fusion of L4-L5 in different sagittal alignments was carried out. OBJECTIVES To test the hypothesis that an L4-L5 fixation in different sagittal alignments causes increased angular motion at the adjacent levels (L3-L4 and L5-S1) in comparison with the intact spine. SUMMARY OF BACKGROUND DATA Clinical experience has suggested that lumbar fusion in a nonanatomic… CONTINUE READING
