【摘要】 作者报告兼施后路椎体间融合术防治下腰椎不稳28例,除2例植骨块脱出再手术,均取得满意疗效。手术成功的关键有5:（1）下腰椎体间（L₄～S₁）手术;（2）植人骨柱比椎体间骨孔直径大1～2mm;（3）稍大坚质片嵌塞骨孔;（4）术后石膏制动;（5）手术面宽敞,采用椎板后移回植术显露。笔者认为本手术对腰椎间盘突出症摘除突出物后潜在的脊柱不稳是一种重要的防治措施。更多还原

【Abstract】 Twenty-eight cases of instability in lower lumbat spine were treated through posterior approach for intervertebral bodies fusion with autogenic bone grafting. In two cases the grafted bone segment slipped into the spinal canal,which need second operation. The results were satisfactory in this series. The important points were five as follows: (1)It was indicated in lower lumbar intervertebral space(L5S1or L4.5); (2)the diameter of the grafting bony colum was l~2mm larger than the hole of removed end-plate and disc; (3)cortical bone segment was pushed into the hole; (4)a plaster bracing was applied postoperatively; (5)using spinous process and lamina osteotomy and replantation technique. Authors maintain that is a important technique to prevent spinal potential instability after excised hernia ted dise and enlarged lateral recess.更多还原
