The production technology department of Guangzhou Sailong completed 3D printing of personalized DDH acetabular tantalum pad

Guangzhou Sailong cooperated with the First Affiliated Hospital of Army Medical University.The surgery was performed by Professor Chen Guangxing, Deputy director of the Department of Joint Surgery, and Professor Wang Fuyou led the 3D model design. The personalized DDH acetabular tantalum pad was prepared by the company's powder bed electron beam 3D printing technology. On the one hand, the personalized design can achieve good matching and reduce the risk of osteoarthritis in the long-term stress concentration of the weight bearing surface. To meet the requirements for precise treatment of acetabular bone defects in developmental dysplasia of the hip (DDH).On the other hand, it solves the problem that the traditional cap bone is still difficult to completely match the surface shape of the femoral head even if it is trimmed, especially the problem that the iliac crest bone is relatively limited in the acquisition and source of the conventional operation, and creates the best means for the anatomical preservation and functional remodeling of the hip joint.Since 2020, more than 30 clinical applications of personalized acetabular pads have been completed.(The Production Technology Departmen of Guangzhou Sailong/Feng Kehan)
