摘　　要：目的综述生物型骨干假体柄的相关研究进展。方法查阅近年来国内外生物型骨干假体治疗四肢骨缺损的相关文献,对假体柄的设计和使用进行总结分析。结果生物型骨干假体具有生物相容性好的优点,不足之处是影响假体柄固定的因素较多、假体稳定性存在个体差异。提高生物型骨干假体柄固定效果的方法主要包括优化假体柄外形结构、增加辅助固定、改进假体柄表面涂层材料和多孔结构,其中以增加辅助固定对假体稳定性的提升作用最为明显,不足之处是该方法会增加手术显露和手术创伤。结论改进生物型骨干假体柄的设计及固定方法有助于提高假体稳定性,在尽量避免增加手术创伤前提下增加辅助固定是重要改进方向。Objective To review the research progress of cementless intercalary prosthesis stem.Methods The literature about the cementless intercalary prosthesis in treatment of bone defects of extremities was reviewed,and the designing and application of prosthesis stem were analyzed.Results Cementless intercalary prosthesis has the advantages of good biocompatibility.However,there are also some disadvantages,including the multiple factors affecting the fixation of the prosthesis stem and individual differences in the stability of the prosthesis.The methods to improve the fixation stability of prosthesis stem mainly include the optimization of prosthesis stem shape,addition of auxiliary fixation,and improvement of coating materials on the stem surface as well as porous structure of the stem surface.Among these methods,augment with auxiliary fixation has the most satisfactory effect on improving the stability of prosthesis.However,the deficiency of the method is the increasing risk of the larger incision exposure and surgical trauma.Conclusion Improving the design and fixation method of the cementless intercalary prosthesis stem can further improve the stability of the prosthesis.Under the premise of avoiding increasing surgical trauma as much as possible,addition of the auxiliary fixation can be a feasible choice to improve the fixation stability of prosthesis.
