The Treatment of Chronic Osteomyelitis with Bone Defect by Liposomal Gentamicin-impregnated Substitution of Bone 庆大霉素脂质体抗菌骨治疗兔慢性感染性骨缺损的实验研究
Anatomical study on lunate bone substitution with pedicled cephaloid bone 带血管蒂头状骨移位替代月骨的应用解剖
As to the effect of the substitution of the prosthesis on the surface stress, normally there are two kinds of stress on the bone surface that is the normal stress and the shearing stress. 对于假体置换对界面应力的影响,通常有骨界面上的正应力和剪切应力两种。
Conclusions: The frozen dried bone allograft is safety in clinical use and it is a perfect substitution of bone autograft. 结论:冷冻干燥同种骨使用安全,保存和运输方便,可替代临床自体骨移植。
Results: The histologic examination exhibited creeping substitution of the newly formed bone for devitalized bone and incomplete reconstruction of the condylar cartilage layers as the implanted condyles were gradually revascularized. 结果:组织学检查发现随着血供逐渐恢复,失去活力的骨被新骨爬行替代,而髁状突软骨的结构未完全恢复;
Conclusions Tissue-engineering bone can repair bone defect, accelerating healing and without "creep substitution", which is a good option in repair of critical segmental bone defects. 结论组织工程骨能加速骨缺损愈合的速度,其修复过程可超越爬行替代阶段;
[ Conclusion] CPC combined with BMP can improve the bone reparation and substitution process in massive bone allograft transplantation for the treatment of large segmental bone defects. [结论]CPC复合BMP对大段同种异体骨移植的愈合及替代有增强和促进作用。
The purpose of this research is, basing on clinical challenges, to fabricate a novel Artificial Compound Substitution Bone Biomaterial ( ACSBB) through the combination of the allograft tissue bank technology, the compound artificial bone transplantation theory and tissue engineering fabrication technique. 从临床应用的角度出发,本课题旨在研究一种利用标准骨库同种异体骨处理技术,结合复合型人工骨替代材料理论和组织工程复合材料合成技术,开发出一种新型复合人工骨生物替代材料。
Results: After the implantation of autologous bone powder, the typical process of "creeping substitution", including the absorption of the bone powder, ingrowth of capillaries and perivascular tissues from the host into the bone powder, and new bone formation, occurred. 结果:自体骨粉再植后经历了骨粉吸收、血管及其周围组织长入、新生骨从缺损断端逐渐向内生长替代移植骨粉的过程,属于典型的爬行替代;
Results The allogeneic and xenogeneic bone treated by different physicochemical method were not only the substitution for bone but also the scaffold material co cultured with seed cells to reconstruct tissue engineered bone. 结果采用不同物理化学方法处理的异体骨或异种骨不仅是天然的骨替代材料,还可作为支架材料与种子细胞复合构建组织工程骨,修复骨缺损。
The creeping substitution of the devitalized bone was mainly manifested by bone resorption within 12 weeks postoperatively. 术后12周以前,灭活骨段的爬行替代以骨吸收表现为主。
Pedicled iliac bone flap transfer without long creeping substitution process, and has the bone entrainment, promote bone healing. 带血管蒂的髂骨瓣移植无需长时间的爬行替代过程,而且具有骨诱导作用,促进骨愈合。
