Magnetic locking mechanism (MLM) for joint arthroplasty

A joint prosthesis assembly comprising:

• a prosthetic head having a recess;
• a prosthetic stem having a protrusion configured to be received in the recess;
• and
• a magnetic prosthesis disposed between the prosthetic head and the prosthetic stem and configured to connect the prosthetic head to the prosthetic stem, wherein at least one of the prosthetic head or the prosthetic stem is coated with a ferromagnetic metal.

A joint prosthesis assembly comprising:

• a prosthetic head;
• a prosthetic stem;
• and
• a magnetic prosthesis disposed between the prosthetic head and the prosthetic stem and configured to couple the prosthetic head to the prosthetic stem, wherein at least one of the prosthetic head or the prosthetic stem is coated with a ferromagnetic metal.
