Orthopedic fixation assembly with helicoid piezoelectric interface

A kit to form an orthopedic fixation assembly, the kit comprising:

• a first lateral component having a first inner surface defining a first helicoid shape;
• a second lateral component having a second inner surface defining a second helicoid shape, wherein the first lateral component and the second lateral component are configured to be assembled together to form an elongated body, wherein, in the elongated body, the second inner surface faces the first inner surface and the first helicoid shape and the second helicoid shape define an interface therebetween, the interface defining an interfacial helicoid shape about a line extending through the elongated body;
• and
• a piezoelectric material configured to be placed in the elongated body at the interface.

A method of making an orthopedic fixation assembly, the method comprising:

• providing a first lateral component having a first inner surface;
• providing a second lateral component having a second inner surface, the second inner surface facing and conformal with the first inner surface;
• providing a piezoelectric material;
• assembling the first lateral component and the second lateral component together to form an elongated body such that the first inner surface and the second inner surface define a helicoid interface about a line extending through the elongated body, with the piezoelectric material positioned at the interface;
• and securing the first lateral component and the second lateral component together to form an elongated body.
