Measurements of bone mineral density of the lumbar spine, femoral neck and Ward's trigone with dual ...

用双能X线骨密度仪测定患者腰椎、股骨颈、Ward's三角区的骨密度，对结果进行分析。

Methods Fifty healthy SD rats were fed for twentytwo months in order to build the model of aging rats, the histology of femoral bone, tibial bone and lumbal vertebra was used to observe, then we evaluated the indexes which reflect the degeneration of intervertebral disc including the quantity of collagen type Ⅱ,Ⅹ of intervertebral disc by the immunohistochemistry methods, the relative area of vascular bud, the thickness of calcified layer and uncalcified layer on cartilage endplate and the indexes which reflect the osteoporosis including the thickness ratio of cortical bone, the relative area of bone trabecula, the bone density, the max stress and straining of bone.

50只健康纯种SD大鼠，喂养22个月，建立老龄大鼠模型，进行股骨、胫骨、腰椎等组织学观察，并评价椎间盘退变的相关指标(椎间盘软骨Ⅱ型和Ⅹ型胶原表达、软骨终板血管芽相对面积、软骨终板钙化层/非钙化层厚度)与骨质疏松的相关指标(骨皮质厚度指数、骨小梁相对面积、骨密度、骨最大应力和应变)的相关性。

Movements of vertebrae during manipulative thrusts to unembalmed human cadavers .

腰椎运动在人类尸体的操控第三波unembalmed 。

Results. No changes were observed at the segments located below the fusion. All the unfused segments above the fusion showed the same significant loss of disc height. Loss of disc height did not depend on fusion parameters, correlated weakly with age and length of follow-up, and correlated highly across adjacent unfused segments.

结果：在融合节段下方的未融合节段未发现任何改变，所有融合节段上方的未融合腰椎的椎间盘高度明显丢失，椎间盘高度的丢失与融合所使用的器械无关，与患者的年齡的随访的时间有一定联系，与距离融合节段的远近关系密切。

To explore the clinical efficacy of anterior vertebrectomy and reconstraction with titanium mesh cage in thoracic and lumbar tuberculosis.

目的探讨一期前路病灶清除并钛网植骨重建术在胸腰椎结核治疗中的临床疗效。

To elevate the surgical treatment of lumbar kyphosis with transpedicular vertebrectomy.

目的］ 总结单节段经椎弓根椎体截骨技术在各种原因所致腰椎后凸畸形矫正中的效果。

Methods 16 cases of thoracolumbar burst fractures with spinal cord or equina cauda injuries were treated with anterior subtotal vertebrectomy, Pyramesh with bone debris intervertebral implantation and Z-plate fixation.

16例胸腰椎爆裂性骨折伴脊髓或马尾损伤患者进行前路椎体次全切除减压，自体碎骨装入Pyramesh钛网后行椎体间植骨，加用Z-plate内固定。

Maxium valum of axial torque were measured by static eccntric loading test on the instrumented spines at last; Another 8 fresh frozen human cadaveric spinal speciments were used in this biomechanical test, the testing constructs used were:〓vertebrectomy and 〓 discectomy, bone-graft with anterior Kaneda device, mesh-cage interbody fusion device, mesh-cage with Kaneda fixation, mesh-cage with posterior pedicle screw system TSRH.

利用腰椎三维运动分析系统进行生物力学稳定性测试及静态偏心加压极限扭转载荷测试。2）取8个新鲜冷藏的人尸脊柱标本，分别行〓椎体全切，〓和〓椎间盘全切，制作损伤失稳模型，依次实施四种重建术式：髂骨块植入加前路Kaneda钢板固定，钛网椎间融合器植入，钛网和前路Kaneda联合应用，钛网和后路TSRH椎弓根系统联合应用。

All underwent surgery recently when we decided to presere the segmental essels wheneer possible.

对29例胸腰椎前路内固定患者的病历资料进行回顾，所有我们决定近期进行手术的患者，尽可能地保留其节段血管。
