Abstract
The present disclosure discloses a shoulder joint prosthesis containing zirconium-niobium alloy on oxidation layer and a preparation method thereof, the preparation method comprises: using zirconium-niobium alloy powder as a raw material, conducting a 3D printing for one-piece molding to obtain an intermediate products of the humeral handle with articular surface and the scapular glenoid plate, and performing Sinter-HIP, cryogenic cooling and surface oxidation to obtain humeral handle with articular surface and scapular glenoid plate. The prosthesis comprises a humeral handle, an articular surface, a humeral head and a scapular glenoid plate, a bone trabeculae is arranged on the outer surface of the upper part of the humeral handle, the upper surface of the scapular glenoid plate and the outer surface of the circular pipe with internal thread.
