文题释义:
骨不连:
指经影像学检查(通常为X射线检查)以及临床检查,骨折已停止愈合,并且估计不会再连接。骨不连的原因主要有局部因素、全身因素、手术以及感染等几个方面,对于骨不连的治疗现在基本上依然使用断端刷新植骨手术方案治疗,根据植入骨成分不同,可将其分为自体骨移植、异体骨植骨或人工合成骨替代物移植等。其中多数的替代材料以骨髓间充质干细胞及生长因子为细胞学基础。
自体红骨髓移植:是基于骨髓间充质干细胞及生长因子基础上的一种微创移植技术。扁骨内的红骨髓富含具有成骨潜力的多种生长因子,骨髓间充质干细胞以及未分化间叶细胞,故成骨能力较强。另外髂骨处抽取骨髓会诱发局部和全身的成骨反应。与骨移植相比较,自体红骨髓移植有明显的优势。且移植的自体红骨髓在周围组织未能建立周围营养的情况下便可以迅速参与到骨折组织的修复与重建,更不存在免疫排斥及伦理学方面的问题。

 

摘要
背景:
骨折愈合是否需要一期红骨髓移植,是否植入间充质干细胞?当股骨粉碎性骨折时进行闭式复位髓内钉内固定术,同期进行自体红骨髓一期移植是否可促进骨折处成骨的作用,尚处于研究阶段。
目的:探讨采取闭式复位髓内钉内固定方法,一期治疗同时给予自体红骨髓移植对骨折愈合的影响。
方法:选择健康新西兰兔20只,麻醉后以30 cm高度质量为5 kg重锤自由下落的做功条件制作兔股骨粉碎型骨折模型。给予2.0 mm直径克氏针髓内固定系统模仿股骨髓内钉内固定术对其进行固定。将兔股骨粉碎性骨折内固定造模成功的右侧股骨定义为骨折内固定组,将其左股骨定义为红骨髓移植组。红骨髓移植组将提取的1 mL自体红骨髓注射于骨折处。于造模后第14,28天分批处死10只兔,测量X射线片上骨折周围骨痂最厚处骨痂厚度;苏木精-伊红染色后光镜观察2组骨折处组织切片中软骨细胞数量及骨小梁相对面积。
结果与结论:①骨折后14 d,骨折内固定组较红骨髓移植组骨折周围骨痂生成厚度明显减小(P < 0.01),差异有显著性意义;②骨折后14 d,红骨髓移植组骨折处软骨细胞生成数量大于骨折内固定组(P < 0.01),骨折愈合速度快于骨折内固定组;③骨折后28 d,骨折内固定组较红骨髓移植组骨折处骨小梁相对面积明显缩小(P < 0.01);④结果提示,红骨髓移植对于闭式复位髓内钉内固定修复兔股骨干粉碎型骨折的愈合具有促进作用。

Abstract:

BACKGROUND: Whether one-stage bone healing with red bone marrow or mesenchymal stem cell transplantation is needed? Whether closed reduction with intramedullary interlocking nailing combined with autologous red bone marrow transplantation can promote osteogenesis in the one-stage treatment of femoral comminuted fracture still remains unclear.
OBJECTIVE: To explore the effects of closed reduction with intramedullary interlocking nailing and one-stage treatment with autologous red bone marrow transplantation on fracture healing.
METHODS: Twenty healthy New Zealand rabbits were selected and anesthetized, and then the models of femoral comminuted fracture were established at the hinder limbs after throwing a 5 kg of hammer from 30 cm height. All rabbits underwent intramedullary fixation using Kirschner wire (diameter: 2 mm); the right limbs served as control groups, and the left limbs as transplantation group, subjected to the injection of autologous red bone marrow (1 mL) into the fracture region. Then the rabbits were respectively killed at 14, and 28 days after modeling, the thickness of thickest callus was measured on X-ray films, and the number of chondrocytes and relative area of bone trabecula in the fracture region were observed through hematoxylin-eosin staining under light microscope.
RESULTS AND CONCLUSION: (1) The thickness of callus formation in the control group was significantly less than that in the transplantation group at 14 days after modeling (P < 0.01). (2) The number of chondrocytes in the transplantation group was significantly more than that in the control group at 14 days after modeling (P < 0.01), and the fracture healing in the transplantation group was faster that in the control group. (3) Compared with the transplantation group, the relative area bone trabecula in the fracture region in the control group was significantly reduced at 28 days after modeling (P < 0.01). (4) These finding indicate that red bone marrow transplantation promotes fracture healing in the intramedullary fixation for femoral comminuted fracture in rabbits.
