摘      要：In this paper,we describe the design and surgical process of personalised pelvic prostheses fixation through 3D printing according to different Enneking pelvic tumour zones:the ilium(Zone I),acetabulum(Zone II),and pubis and ischium(Zone III).A 3D model of the pelvis was reconstructed using imaging data,and the parameters on the planes of the acetabulum and pelvic incisal margin were *** main body of the pelvic prosthesis was constructed,a porous structure was designed on the bone-prosthesis interface,and the movement paths,lengths,and diameters of screws were *** combining the pathological model and osteotomy guide,limb salvage reconstruction was performed in patients with pelvic *** and postoperative data were compared to verify the prosthesis *** investigation revealed that the long-term survival of pelvic reconstruction prostheses depends on accurate matching with the bone defect area,good initial stability,and a porous structure to allow bone ingrowth.
