Objective:To study the effects of mesenchymal stem cells(MSCs) transplantation on new bone formation during transport distraction osteogenesis in a goat model of calvarial defect.Method:8 adult goats were randomly divided into group A (n=4) and group B(n=4) .A calvarial defect and a transport disk were created in all animals , and a custom-made distractor was used for repairing the cranial defect. The group A goats were injected with autologous MSCs into the distracted region, whereas the group B...

Objective:To study the effects of mesenchymal stem cells(MSCs) transplantation on new bone formation during transport distraction osteogenesis in a goat model of calvarial defect.Method:8 adult goats were randomly divided into group A (n=4) and group B(n=4) .A calvarial defect and a transport disk were created in all animals , and a custom-made distractor was used for repairing the cranial defect. The group A goats were injected with autologous MSCs into the distracted region, whereas the group B with injection of physiological saline were used as controls. At 4 weeks after end of distraction, all animals were killed, and the distracted callus was obtained and prepared for histological and scanning electron microscopy analysis.Result:The new bone formation in the distraction gap at group A was superior to that of group B after transport osteodistraction for repairing of calvarial defect.Conclusion: Transplantation of autologous MSCs may have beneficial effect on bone formation following transport distraction osteogenesis in a goat model of calvarail defect.

目的 :研究自体骨髓间充质干细胞 (MSCs)对采用输送盘骨牵张术修复山羊颅骨缺损效果的影响。方法 :将成年雄性山羊 8只 ,随机分为A、B两组 ,每组 4只。在动物颅顶区制造全层颅骨缺损和输送盘 ,用自行研制的牵张器行输送盘骨牵张术修复颅骨缺损。牵张结束后 ,在A组动物牵张区注入体外培养的自体骨髓间充质干细胞 ;B组同期注入生理盐水作对照。在牵张结束后的第 4周处死A、B两组动物 ,取牵张区新生组织标本行组织学和扫描电镜分析。结果 :移植MSCs的A组动物牵张区新骨生成速度和钙化程度显著高于B组动物。结论 :局部移植MSCs可能有促进牵张成骨的作用。

Methods A calvarial defect (25 mm×10 mm) and a transport disk (25 mm×(10 mm)) was created in 10 adult goats. A self-made bifocal distractor was used to repair the cranial bone defect in eight animals, of which four distracted animals were killed at the 4th and 8th weeks respectively. Gross X-Ray, histological and scanning electron microscopy were performed to evaluate the state of the bone...

Objective To study the effect of transport distraction osteogenesis in repair of calvarial defect of goats. Methods A calvarial defect (25 mm×10 mm) and a transport disk (25 mm×(10 mm)) was created in 10 adult goats. A self-made bifocal distractor was used to repair the cranial bone defect in eight animals, of which four distracted animals were killed at the 4th and 8th weeks respectively. Gross X-Ray, histological and scanning electron microscopy were performed to evaluate the state of the bone healing and regeneration. The other two goats (sham operation control) were free from distraction but used as control after sacrifice at 8th week. Results All calvarail defects were repaired by transport distraction osteogenesis, with newly formed bone found in the distraction gap. The calvarial defects of the control goats were not healed by itself. Conclusions The technique of transport distraction osteogenesis is an alternative method for repair of calvarial defect resulting from trauma or neurosurgical operation.

目的探讨用输送盘牵张成骨技术修复山羊颅骨缺损的可行性及效果。方法选用成年雄性山羊10只,在其颅顶区制造全层骨缺损(25mm×10mm)模型。通过自行研制的两点式牵张器对其中8只动物进行输送盘骨牵张术。在牵张结束后的第4和第8周各处死4只山羊。通过X线片、组织学及扫描电镜等方法评价缺损修复和牵张间隙内新骨生成情况。另外两只不进行输送盘牵张的山羊,与固定8周实验组动物同期处死作为对照。结果实验组山羊的颅骨缺损均被成功修复,牵张间隙内有新骨再生。对照组颅骨缺损区没有自行关闭。结论输送盘牵张成骨术可以用来修复由于创伤或脑外科手术造成的颅骨缺损。

PURPOSE:This study was aimed to set up a new method for reconstruction of maxillary defect with distraction osteogenesis through an animal experiment. METHODS: 11 adult goats were randomly divided into 2 groups (9 in the experimental group and 2 in the control group) in this study. 3 subgroups were set up in the experimental group based on the consolidation period. Other 2 goats were chosen as the control group. Maxillary defect was made firstly through partial maxillectomy for the experimental group....

PURPOSE:This study was aimed to set up a new method for reconstruction of maxillary defect with distraction osteogenesis through an animal experiment. METHODS: 11 adult goats were randomly divided into 2 groups (9 in the experimental group and 2 in the control group) in this study. 3 subgroups were set up in the experimental group based on the consolidation period. Other 2 goats were chosen as the control group. Maxillary defect was made firstly through partial maxillectomy for the experimental group. Length of the defects was from 12 to 14mm with an average of 12.7mm. A transport disc was then made through anterior Le Fort I osteotomy and it would be shifted backward for the closure of the defect. Only maxillary defect was made for the control group. Distraction was activated after a latency of 7 days at a rate of 0.4mm twice a day for 15-18 days. RESULTS: Bone defects in the maxilla were well repaired when the transport disc was distracted back to its original position. Radiology and histology demonstrated good new bone formation in the distraction gap. CONCLUSIONS: Transport distraction osteogenesis would be a reasonable method for reconstruction of maxillary defect.

目的:结合上颌骨的解剖生理特点,探讨采用传送盘回复式牵引成骨修复上颌骨缺损的可行性。方法:11只成年山羊,随机分为实验组和对照组。其中实验组9只,按固定期不同分为1、2、3个月组,每组3只;对照组2只。实验组山羊通过手术制作上颌骨前部节段性缺损,缺损长度12~14mm,平均大小12.7mm。同期制作缺损前方传送盘并使之后退,关闭缺损区,安置牵引器,通过牵引将传送盘回复原位。术后7天开始牵引,每天2次,持续15~18d,每次0.4mm,采用大体、影像学及组织学观察缺损区愈合情况。结果:传送盘牵引复位后,缺损区被新生骨修复,X线、三维CT及组织学检查显示,新骨形成良好,新骨形成方式符合传统牵引成骨的成骨方式。结论:传送盘回复式牵引成骨符合上颌骨的解剖特点,具有一定的临床可行性。
