1.
Objective To study the effects of unilateral graded facetectomy on lumbar spinal stability in biomechanics and to investigate the biomechanical characteristics of articular process and the safety of decompression produre for lumbar disc herniation.
方法选用5具新鲜成人尸体脊柱L4/5功能单位(FSU),通过分级切除L4/5节段的左侧小关节,共造成5种实验验模型(正常脊柱结构、小关节切除外侧1/4、小关节切除外侧1/2、小关节切除外侧3/4、左侧小关节全切除),运用脊柱三维运动实验机测试各模型的稳定性。
2.
81 MPa after total bilateral facetectomy, and significant increase in segment motion was found when the facet resection was incremented on unilateral or bilateral facetectomy.
活动节段的运动范围在单、双侧小关节切除时有明显增大 ,其最突出的倾向表现在轴向旋转和后伸旋转时 ,而前屈时最小。
3.
Objective To observe the biomechanical effects of unilateral graded facetectomy on lumbar spinal stability.
05);b)在左/右侧弯和左/右轴向旋转状态下,小关节切除1/2以上的各组均与正常组有显著性差异(P<0。
2) Resection of joint capsule
小关节囊切除
5) arthrectomy

跟距关节融合和跗中关节离断术
Syme amputation
踝部截肢时，胫骨下关节软骨切除、保留软骨下骨质，切除距骨和跟骨，保留跟骨后部骨膜和跟下脂肪垫，将其与胫骨残端骨膜缝合。残端负重性能好，也方便安装假肢。
