摘要
为探寻大块骨缺损修复方法的新途径,进行了自体骨膜游离移植修复骨缺损的实验及临床研究。实验用42只兔,于双侧胫骨作人工骨缺损模型(6mm×18mm×5mm)。一侧随机植入自体游离骨膜片,另一侧不植入,作为对照。以组织学、X线和放射性同位素为观察指标,研究成骨过程。结果表明,骨膜植入侧骨缺损的愈合比对照侧缺损的愈合快一倍。原因可能是骨膜提供了大量成骨细胞并直接呈膜内成骨而非软骨内化骨。在此基础上,为21例骨缺损患者应用自体胫骨骨膜片植入治疗骨缺损,面积最大10.5cm×4cm×4cm,最小2cm×2cm×2cm;其中17例为良性骨肿瘤,4例为骨慢性感染。骨缺损均得到修复,关节功能恢复满意。为腔洞性骨缺损的修复提供了一种新方法。
In order to find a new method to repair large bone defect, the free periosteum autograft was investigated in experiment, and then the method was used clinically. In the experiment, a 6mm×18mm×5mm bone defect was made at upper end of both tibiae of 42 rabbites. The periosteum of each rabbit was cut into 1mm cubes, and implanted randomly into the tibial bone defect on one side and the other side was used as control. After 2, 4, 8 weeks, the bone defects of each group were examined for bone formation by roentgenography, radionuclide and histology. The results showed that the defects treated by free periosteum autografts healed twice as fast as the controls (its natural healing). The reason probably was that the periosteum provided with many osteogenic cells. On the basis of these results, 21 cases of bone defects (the largest was 10.5cm×4cm×4cm, the smallest was 2cm×2cm×2cm) including 17 cases of benign bone tumor and 4 cases of chronic osteomyelitis, were treated by free periosteum autografts. The defects were all healed, and the function of the joints was restored
