摘　　要：目的 :在哈氏棒手术中应用椎板三角形截骨方法 ,提高哈氏棒内固定系统的稳定性 ,减小手术难度和使内固定系统的安置更易进行 ,使棒钩的弯曲面与椎板的接触面贴合合理、紧密。方法 :总结哈氏棒手术的经验 ,设计椎板三角形截骨。结果 :本组 80例采用椎板三角形截骨 ,减少了手术难度 ,缩短了手术时间 ,提高了内固定系统的效用 ,有避免术后断棒、脱钩和减小脊柱旋转的作用。结论Objective:Use the method of triangular osteotomy on lamina of vertebra in Harrington′s rod fusion,to rise stability of Harrington′s rod,reduce diffculty of operation,facilitate insertion of Harrington′s rod,tighten up and rationalize contact surface of rod-hook curve and Lamina of vertebra.Methods:Design and use triangular laminectomy in 80 cases based on experience of Harrington′s rod fusion.Results:It can decrease the difficulty of operation,shorten operation time and rise effect of internal fixation system by using triangular osteotomy on lamina of vertebra in Harrington′s rod fusion.It also can prevent breaking of rod,dislocating of hook and decrease possibility of rotation of spine after operation.Conclusion:It′s a good operation procedure to use triangular osteoectomy on lamina of vertebra to enhance compatibility of internal fixation device and spine,diminish postoperative complications.
