Abstract:
[Objective]To investigate the ability of repairing bone defect with the combination of recombinant human insulin-like growth factor-1(rhIGF-1),coralline hydrolyapatite(CHA) and autogeneous red bone marrow(ARBM) by way of imaginology.[Method]Bilateral middle radius periosteum-bone defects (11mm in length) were created in 54 Chinese rabbits,and were ramdonly devided into 6 groups(each group containning 18 radial defects of one forearm): group A, defects transplanted with rhIGF-1/CHA/ARBM,group B,with CHA/ARBM,group C,with rhIGF-1/CHA,group D,with CHA,group E,with autograft,group F,no implant.At 2,4,8,and 12 weeks postoperation,the repair effects of defects were evaluated by observation of gross appearance,roengenodiagnosis and radionuclide bone image assay.[Result]In group A,radiological and bone density image analysis showed that the defects were bridged well at 12 weeks postoperatively and was significantly superior to those of any other groups(P0.05).[Conclusion]The recombinant compound rhIGF-1/CHA/ARBM,which possesses the potential ability of osteogenesis,osteocondution and osteoinduction for bone defect repairing,can enhance bone healing and serve as a new type of bone substitute.
