The labial cortical plate and alveolar bone below the level of the incisors apices are sectioned with a No.701 fissure bur. 唇皮层板和牙槽骨的水平以下的切牙根尖的切片,以第701号裂刺。
Objective: To evaluate the histopathology and tetracycline fluorescence marked changes in cortical osteoporosis of the local site of fracture after inter plate fixation for stress shielding. 目的:了解骨折钢板内固定对骨折局部骨皮质的病理组织学改变与四环素荧光标记的变化。
Conclusion When there is a cortical defect in the medical side of the femur, using a bone plate to reconstruct it can recover the integrity of the bone, increase the successful rate of the plate internal fixation, and this method is worth applying in the clinical. 结论应用异体骨板重建股骨干内侧皮质缺损,可较好的恢复股骨干内侧皮质的完整性,增加钢板内固定的成功率,值得在临床上推广应用。
Double opening-door laminoplasty was conducted in posterior operation and anterior graft was from autologous cortical iliac bone with titanium plate for internal fixation. 后路采用“双开门”椎管成形减压术,前方植骨均为自体三面皮质髂骨,均加颈椎前自锁钛板固定。
[ Results] CD The microvessel morphology of the cortical bone observation: on the control group, a large area ischemia zone of the cortical bone beneath the steel plate was seen at 2 weeks after operation and not disappeared until 6 weeks after operation. 【结果】①钢板下皮质骨内微血管形态观察:术后2周,对照组钢板下皮质骨出现大面积缺血区,并持续到术后6周;
At 19 weeks, a few PV containing neurons were found in deep part of cortical plate. 19周,少数含PV神经元出现于皮质板深部(相当于Ⅵ层处)。
Results The shifted buccal cortical bone plate was alive and new bone was formed in distraction area. 结果被移动颊侧骨板正常成活,牵引区成骨良好。
Conclusion: The SRP abated the osteoporosis of the cortical bone under the plate, furthermore, it could restore the structure and mechanical property of the osteoporotic bone to normal with the plate at the place. 结论:应力松驰接骨板减轻了板下骨骨质疏松的发生,在不去除接骨板的情况下,可使疏松板下骨形态结构及力学性能逐渐恢复。
The cortical bone underneath the plate was harvested at 2, 4, 8, and 12 wk postoperatively. 术后2、4,8和12周截取接骨板下皮质骨,在扫描电镜下观察骨胶原纤维。
Treatment for Nonunion of the Long Bone with Allograft of Cortical Bone Plate ( 22 Cases Report) 同种异体皮质骨板内固定治疗骨不愈合(附22例临床分析)
The strength of the allograft cortical bone plate was similar to the segment of fixed bone, the histocompatibility was well without immunological rejection, and elasticity of the implant was the same with human bones. 同种异体皮质骨板的强度接近正常骨质,组织相容性好,无排异反应,其弹性模量与固定段骨质相近。
However, as the brain developed, positive signals were confined to the cortical plate, where new-born neurons had begun to differentiate. 但随着脑的发育,阳性信号逐渐局限在新生神经元开始分化的皮质板位置。
