1 results about "GLENOID FOSSA PROSTHESIS" patented technology

This application relates to the field of orthopedic artificial joint design and manufacturing technology, and in particular to a metal-ceramic total shoulder joint prosthesis system and its preparation method. The metal-ceramic total shoulder joint prosthesis system includes a humeral stem prosthesis, a tapered adapter prosthesis, a humeral head prosthesis, and a glenoid fossa prosthesis connected sequentially. The humeral head prosthesis and the tapered adapter prosthesis are both formed using 3D zirconium-niobium metal printing or forging. The humeral stem prosthesis and the glenoid fossa prosthesis are integrally formed using 3D printed zirconium-niobium alloy. A metal-ceramic interface layer formed by the oxidation of the zirconium-niobium surface is provided at the relative motion contact surface of the humeral head prosthesis and the glenoid fossa prosthesis. The metal-ceramic total shoulder joint prosthesis system provided by this application has advantages such as longer service life, high wear resistance, low wear rate, no osteolysis, and no prosthesis loosening.
