Abstract

The invention discloses a suspended customized assembly total sacrum prosthesis and a customization method. The suspended customized assembly total sacrum prosthesis comprises a prosthesis body, a right ilium wing fastener and a left ilium wing fastener. The suspended customized assembly total sacrum prosthesis has the advantages that the suspended customized assembly total sacrum prosthesis can rapidly promote bone cell generation and bone fusion, restore sacrum functions and achieves reconstructed waist sacroiliac joint stability.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a suspension-type custom-assembled total sacral prosthesis and a custom-made method. Background technique [0002] The sacrum is the connecting body between the lumbar spine and the pelvis, acting as a link between the preceding and the following. The number of patients with sacral malignant tumors and invasive tumors has increased. With the advancement of medical technology and technology, total sacral tumor resection or piecemeal resection has been widely carried out, and the survival time of patients is prolonged. There are many complications in patients with screw-rod bone graft reconstruction. The traditional reconstruction method takes a long time to operate, cannot completely imitate the original biomechanical structure, is difficult to meet the biomechanical conduction of the original pelvic anatomy of the human body, lacks mechanical support, bone defe...
