【摘要】 目的恢复患者正常解剖关系和脊柱的稳定,消除症状,提高生活质量。方法应用钉钩系统单节段固定加上峡部植骨融合治疗青少年腰椎峡部不连。结果5例患者分别随访12~18个月。腰部活动恢复满意,术后3个月腰痛症状完全消失。术后4个月X线示峡部裂消失,植骨融合满意。结论钉钩固定系统SSE为节段性固定,设计力臂短,应力集中,固定牢固,确保植骨融合而达到长久的生理稳定。避免了多节段融合对脊柱的活动度、力学、生长发育等不良影响,达到“生理性重建”。更多还原

【Abstract】 Objective The aim of this study is to repair the anatomy and regain the stability of the lumbar discontinuous isthmus treated by hook system Hs by single section fixation in teenager, as to relief the symptom and improve the life quality of the patients. Methods 5 teenagers were diagnosed lumbar discontinuous isthmus and treated by fusion and single section fixation by HS. Results All cases were followed up for 12 to 18 months. The recovery of the lumbar activity and the fusion rate were satisfied. Lumbar pain disappeared in 3 months and the isthmus splits showed in X-ray image were gone in 4 months in all cases. Conclusion Compared with the muti-section fixation which cause side effect to the activity, mechanics, growth and development of the spinal column, single section fixation by HS has the advantage of short designed force arm, force concentration, mini-invasive and reliable physical and physiological fixation which improve the fusion rate as to achieve physiological reconstruction of the spinal column.更多还原
