摘要
目的 作者设计一种新型脊柱内固定器,该生物力学测试对该器械进行评价。方法 取7具新鲜成人尸体T10-L4脊柱标本上,模拟L1骨折后安装该器械进行脊柱三维运动范围和前屈-压缩刚度测试。结果 该器械能在屈伸、侧弯运动方向上显著加强损伤节段的稳定性(P<0.001～0.01)。使轴向旋转运动恢复正常运动范围(P<0.05)。结论 新型脊柱内固定器(池氏钉)设计合理,对损伤脊柱节段固定具有较强稳定性,不失为一种较为理想的内固定器械。
Objective To evaluate the new designed spinal internal fixator(CYL) with the biomechanical study . Methods A model of LI body fraeture was produced on seven specimens of fresh adult cadaver spine from T10 to L4.CYL was applied in the specimen to Strength the injured level . Ranges of three dimensional movements and stifness under flexion - compression were measured in normal . injured and fixed states. Results The spinal stability with CYL were increased signifieantly in flexion. extension, lateral bending (p< 0.001 -0.01 )and restored to normal in axial rotation .Mpression( P < 0.05) .Conclusion The new - designed CYL, system is a ideal spinal internal fixation in treating the thorocolumbal spinal fractures..
