Abstract:
[Objective]A new limited contact femoral supracondylar interlocking intramedullary nail(LCFSIIN) was made,which was part of a new custom-made hemi-knee joint,to improve the results of childrens' limb salvage.[Method]A new LCFSIIN was performed and the stress of bolts,intramedullary nails and bone were analyzed by finite dement analysis(FEA) while the bolts were implanted in different angulafions-0?,15?,30?,45?and 60?.[Result]The results of FEA show that the stress of bolts,bone and nails with 15? insertion angles of bolt was the tiniest and well distributed.Stress of bone with 0? insertion angles was more obvious than that with 15?,30?and 45?.The more the angles,the stress of proximal bolt became more obvious and the stress of distal bolt decreasing.[Conclusion]This new LCFSIIN can reduce destruction of biological environment of bone and is easy in use in limb salvage surgery of allograft.
