摘要
目前,比较复杂的股骨远端C3型骨折和膝外翻的矫形手术都需要应用到独立的股骨内侧接骨板。以往术者都是将对侧股骨的外侧接骨板进行预弯曲,以达到贴近骨骼自然形态的目的,而这种冷变形会改变接骨板的金相结构,进而破坏接骨板的生物力学,接骨板螺钉孔的位置有时也会影响到骨折的愈合情况。与传统制造技术相对比,3D打印技术作为"第三次工业革命"的核心技术,不必事先制造模具,不必在制造过程中去除大量的材料,也不必通过复杂的锻造工艺就可以得到最终产品,更适合于难加工材料的制造、外形设计检查、装配检验和快速反求工程等。本文将股骨远端内侧接骨板的个性化设计与3D打印技术相结合,从接骨板的应用、3D打印技术的现况及其应用于制作股骨远端内侧个性化解剖型接骨板的前景等方面进行了综述。
Currently,independent clinical medial femoral plate is more needed to apply in more complex C3 distal femoral fractures and knee valgus orthopedic surgery.The doctors always pre-bent the contralateral femoral lateral plate in order to achieve close to the natural shape of the bone.The cold deformation of the plate can change the metallographic structure and the biomechanics,and the position of the screw holes in the plate may also affect the healing of fractures.Compared with traditional manufacturing techniques,3D printing technology as a core technology in ＂third industrial revolution＂,instead prior manufacture of molds,removing the large amount of material in the manufacturing process and the complex process of forging a final product,it is more suitable for difficult to machine materials,manufacture,inspection shape design,assembly,testing and fast reverse engineering.Therefore,a personalized interior distal femoral plate with 3D printing technology was designed,and the application of the plate,the current situation and prospects of 3D printing technology and other aspects were summarized in this article.
