The present invention relates to the technical field of artificial prostheses, and particularly to a
surface replacement prosthesis for the
elbow joint. The
surface replacement prosthesis for the
elbow joint includes: a prosthetic
elbow joint head, on which an installation groove is formed, and the installation groove is installed at the distal end of the
humerus; a connecting portion, one end of which is connected to the prosthetic elbow joint head, and the other end extends along the proximal end of the
humerus; and a
bone grafting groove, which is arranged in the installation groove and is used for accommodating implanted bone fragments. The
surface replacement prosthesis for the elbow joint provided by the present invention does not limit the degree of freedom of the patient's elbow joint and solves the problem of limited movement of the traditional elbow joint; moreover, when using this surface replacement prosthesis for the elbow joint, the amount of
osteotomy of the patient's elbow joint is small, which is beneficial to the
recovery and later revision of the patient's elbow joint; in addition, a
bone grafting groove is also provided for implanting bones into the
bone grafting groove to supplement the patient's
bone mass, which is beneficial to reducing the weight of the elbow joint part, improving the patient's comfort, and after long-term
recovery, the bones in the bone
grafting groove can grow together with the
humerus, thereby restoring the
normal shape and function of the humerus.
