目的:研究用bBMP胶原珊瑚复合人工骨修复股骨头骨缺损的生物力学变化。
方法:建立狗双侧股骨头内骨缺损模型, 4周后分为5组:复合人工骨组、肌骨瓣组、单纯珊瑚组、对照组、正常组。植入后16周行病理学检查及生物力学测定。
结果:人工骨组的骨缺损消失或显著变小, 与对照组相比有显著性差异。人工骨组软骨下骨的抗压强度及弹性模量较对照组及正常组低。
结论:复合人工骨有较强的修复股骨头骨缺损的能力, 但不能改善软骨下骨的生物力学性能。 |

Abstract:
Objective:To study the biomechanical changes of bBMP collagen coral composited bone substitute for the treatment of canine bone defect of the femoral head.
Methods:Canine bone defect of bilateral femoral head was established.After 4 weeks,they were divided into 5 groups:Ⅰ.composited bone substitute group;Ⅱ.Muscle pedicle bone group;Ⅲ.simple coral group;Ⅳ.control group;Ⅴ.normal group.Pathological and biomechanical changes of femoral head were studied at 16 weeks after treatment.
Results:Compared with control group,the bone defect of group I was much smaller.The maximum stress and modulus of elasticity of subchondral bone of group I were lower than that of group V and group Ⅳ.
Conclusion:The composited bone substitute possesses a superior property for repairing bone defect of femoral head,but it is unable to improve the biomechanical property of subchondral bone of femoral head. |
