摘　　要：选用5具新鲜成人尸体脊柱T4/5,T7/8及T11/12脊柱功能单位(FSU),分别切除T4/5,T7/8,T11/12节段的右侧关节突,分别造成3种实验模型(正常脊柱结构、右侧关节突切除外侧1/2,全切除),运用脊柱三维运动实验机测试各模型的稳定性.结果示下胸椎单侧关节突全部切除对脊柱旋转产生影响(P=0.000 755).在胸椎减压手术过程中手术需要保留下胸椎的关节突,如果需要切除时可以辅以内固定系统.Use the vertebral column FSU T4/5, T7/8 and T11/12 function spinal unit （FSU） of 5 adult cadavers was used and facetectomy was performed on right articular process of the above FSU resulting in 0 , 1/2, total facetectomy of unilateral facets. The stability of each model was determined using three dimension movement test machine of vertebral column. In the lower region, the stability was disturbed （P = 0. 000 755）in the Levotorsion and Dextrotorsion, Facets are need to bepreserved in the thoracic decompression, but if it is to be dissected in the operation, the internal fixation systems are helpful.
