Histologically, in 12 weeks postoperatively, the outer layer of the callus in the experiment groups was lamellar bone and the center were trabecular bone, myeloid tissue and partial degrading carrier; 组织学检查证明,实验组术后12周骨痂外层形成板层骨,中央形成小梁骨及骨髓组织,材料部分吸收;
Cartilage is gradually coverting into woven bone at 2 weeks, Lamellar bone appeared at 4 weeks. 2周软骨细胞向幼稚的编织骨转化;4周板层骨形成;
Ectopic osteogenesis of CPC/ BMP composite bone cement is distinct, and lamellar bone can form within 4 weeks, proving the strong osteo-induction capacity of the materials. 新型CPC/BMP复合骨水泥异位成骨作用明显,4周即能快速形成板层骨结构,证明该新型复合材料具有较强的诱导成骨活性。
After the two planting materials implants 26 weeks, formed same bone union-shape in the cortex bone, the surface was encysted by new lamellar bone. 两种种植体植入26周后,于皮质骨内形成了近似相同的骨结合形态。两种种植体的表面都由新生的板层骨包绕。
In weeks 8~ 16 after operation, the new bones was formed continuously, the artificial bone was gradually rebuilt to mature lamellar bone, bone trabecula, and medullary cavity. 8~16周新骨继续生成,人工骨逐渐改建为成熟的板层骨、骨小梁和髓腔结构。
Histological changes at 12 weeks after operation in the two groups: In high energy shock wave group 1, synostosis was observed, bony callus turned to mature and transformed to lamellar bone; 两组术后12周时组织学改变,高能震波1组出现骨连接,骨痂成熟并朝板层骨转化。
At 32 weeks post-operation in experimental group, the defects were well repaired grossly. Histologically, there were bony healing and lamellar bone formation, in experimental group fibrous healing and woven bone formation in control group. 32周大体观察实验组骨修复较好,组织学显示有板层骨形成,连接处骨性愈合,实验对照组有编织骨形成,连接处纤维愈合。
Lamellar trabecular bone formed at 8 weeks; 8周时,形成板层状小梁骨;
Histologic analysis of bone harvested from the augmented site showed new lamellar bone formation. 术后12周植骨部位组织学表现为排列不规则的板层新生骨,可见大量的成骨细胞突起。
The reconstitution of reticulated bone, the formation of the lamellar bone and new haversian system could be observed during 8-10 POW. 术后8~10周可见网织骨普遍融合重建,形成板层,新的哈佛系统形成;
By 6 weeks, callus in the common fracture model was composed of mature lamellar bone, although in the osteoporotic fracture model hyaline cartilage persisted, suggesting a delay in differentiation. 术后6周,一般骨折组骨折端软骨痂为编织骨取代,而骨质疏松性骨折组骨折端则仍有透明样软骨存在,其软骨痂向骨性骨痂转化缓慢;
At 12 weeks, the frozen mandibles and ilia had formed lamellar bone. 12周时冷冻骨及髂骨皮质形成较成熟的板层骨。
Result: At the 16th~ 24th week after the operation, the cartilage cell and lamellar bone were observed in the experimental group. Compared with the control group, the dura adhesion in the laminoplasty segment decreased significantly ( P < 0.01). 结果:实验组术后16~24周复合人工椎板界面观察到软骨细胞及板层骨,硬膜粘连程度比对照组明显减轻(P<0.01)。
Results ① 12 cases ( 14.8%) with skull defect were underwent autogenous rib graft or outer lamellar skull bone implantation, and gained good effects. 结果:①颅骨缺损12例(14.8%),采用自体肋骨或颅骨板移植获得良效;
Histological observation demonstrated that in the surface area, new bone integrated well with titanium mesh and was enforced by titanium mesh ( like cortical bone), and in the middle area large amount of lamellar bone formed. 磨片的组织学检查证实,在支架中有大量成熟的新骨形成,并与钛网愈合良好。
In the xenograft group, well-arranged new born bone trabecula, which was close to lamellar bone, was found on the right side; 异种骨组右侧新生骨骨小梁排列整齐,近似板层骨;
At 12th week, woven bone tissue became thick and intensive, and turned into typical lamellar bone, osteocytes were trend to be mature, and with angiopoiesis and its invasion, irregular medullary cavities were formed. 12周时编织骨增厚密集,呈典型的板层骨结构,骨细胞趋于成熟,有血管形成和长入,不规则骨髓腔出现。
In group B, at 8th week, fibroplasia could be found and the material was absorbed partly.; at 12th week, new bone formation was found in the juncture of implant and host bone tissue, and bone trabeculae and lamellar bone were appeared. B组:8周纤维组织增生,材料部分吸收。12周植入区两端与宿主骨交界处,新骨增生,可见骨小梁和板层骨。
