Abstract (en)
[origin: WO2012041571A1] A method for improving the strength characteristics of orthopedic prostheses, such as femur necks, femoral stems, cotyloid elements, systems of the spinal column and the like, comprising the step of: starting from a prosthesis made of metal, subjecting the prosthesis to a peening treatment to improve the surface hardness of the prosthesis and eliminate micro-scoring caused by the machining of machine tools, the method further comprising a subsequent step of performing a surface finishing treatment by vibration finishing.
