【Abstract】 Objective To report the experience on lumbar spondylolisthesis treated by posterior lumbar intervertebrae fusion(PLIF) and pedicle screw fixation. Methods 36 cases with isthmic (30 cases), traumatic (1 case) and degenerative (5 cases) spondylolisthesis were treated with posterior lumbar interbody fusion with autograft of ilium fixation by and pedicle screw system. Among them, 18 cases were classified as degreeⅠ, 15 as degree Ⅱ and 3 as degree Ⅲ. Results All cases were followed up for 6～24 months. All cases got bony union in 6 months postoperatively. No looseness, protrusion and breakage of internal fixator were found. The results were excellent in 14, good in 20 and fair in 2. Conclusion PLIF and pedicle screw system fixation for spondylolisthesis can provide good reduction, rigid fixation, complete decompression as well as high rate fusion.更多还原
