Abstract

The embodiment of the invention provides a shoulder joint fusion prosthesis. The prosthesis comprises a locking piece and a humerus metaphysis part; the first end of the humerus metaphysis part is connected with a glenoid cavity through the locking piece; the second end of the humerus metaphysis part is connected with a humerus osteotomy end; the humerus metaphysis part can be mechanically stabilized at the initial stage of reconstruction through the locking piece; a boss penetrating through the glenoid cavity to be embedded into the bone of a scapular neck is arranged on the end face of the first end of the humerus metaphysis part; the resistance capacity of the prosthesis to shear stress in all directions can be effectively improved; several first holes are formed in the boss, so that bones grow into the first holes quickly; the purpose of biological fusion is achieved; the stability of the shoulder joint after reconstruction is further enhanced; medium-and-long-term biological stability after reconstruction is achieved; and the fusion rate after reconstruction is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a shoulder joint fusion prosthesis. Background technique [0002] Reconstruction of the scapular girdle is a complex project after resection of the scapular bone and soft tissue tumors within safe surgical margins. [0003] The current reconstruction methods mainly include bone graft reconstruction, prosthetic reconstruction, bone graft combined with prosthetic reconstruction, etc. In bone graft reconstruction, there are methods such as allogeneic or autologous bone joint transplantation, tumor bone inactivation and replantation. The disadvantage is that the grafted bone may cause shoulder instability due to lack of muscle, ligament maintenance or non-fusion with the host bone. , or even dislocation, which makes it difficult to perform the function of the reconstructed upper limb or cause chronic pain. In prosthesis reconstruction and bone graft combined with prosthesis...
