  • Patent number: 10517659
    Abstract: Various systems, devices, and methods for improved bone fixation are disclosed. The system includes a bone plate and a plurality of variable angle screws. The bone plate comprises titanium and the variable angle screws comprise a TiMo alloy treated to have a hardness of at least 35 HRC. A method of manufacturing an implant is also disclosed. The method includes machining the TiMo alloy having a first hardness value and a first % elongation to form an implant; heat treating, quenching, and ageing the bone fastener to have a second hardness value that can be greater than the first hardness value and a second % elongation that can be both less than the first % elongation and greater than about 3% elongation.
    Type: Grant
