Progress of Personalized Interior Femoral Anatomical Plate with 3D Printing Technology / 现代生物医学进展

ABSTRACT

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.
