Abstract

The invention provides a vertebral body prosthesis which comprises an upper vertebral body for being connected with an occipital bone condyle, a lower vertebral body for being connected with a vertebra, and a connecting block arranged at the bottom of the upper vertebral body, facing the lower vertebral body and used for connecting the upper vertebral body with the lower vertebral body. The problem that a prosthesis in the prior art is low in utilization efficiency is solved.

Description

technical field [0001] The invention relates to a medical prosthesis, in particular to a vertebral body prosthesis. Background technique [0002] Diseases of the atlantoaxial joint are becoming more and more common. Osteoarthritis is a degenerative disease, and there are also diseases such as atlantoaxial dislocation and tumors. Among them, if a tumor occurs in the atlantoaxial spine, the entire atlantoaxial joint must be excised. This requires a prosthetic implant that can replace the atlantoaxial joint. It is difficult to achieve perfect results with general fusion devices, because the prosthesis needs to be fixed with the occipital condyle or nearby parts with good bone quality, and the shape design of general fusion devices is not good. Allows for fixation with the occipital condyle, currently such prostheses require custom solutions. [0003] However, there may be some differences between the design in the 3D software and the actual operation during the operation, and ...
