Abstract
A prosthetic device can include a neck defining an upper surface and a sidewall extending from the upper surface, an opening defined by the sidewall and extending into the neck, one or more interior surfaces extending into the neck from the opening to define a female receiving cavity, and a radial head including a male protrusion received within the female receiving cavity through the opening.
Claims17
A prosthesis, comprising:
- a neck defining a sidewall extending circumferentially around the neck, the sidewall defining a sidewall opening;
- a female receiving cavity defined by one or more interior surfaces extending into the neck from the sidewall opening, a first surface of the one or more interior surfaces defining a first threaded hole extending into the neck;
- a stem extending from the neck;
- and
- a radial head defining a lower surface and a male protrusion extending from the lower surface, the male protrusion defining a second threaded hole extending into the male protrusion, the second threaded hole configured to align with the first threaded hole when the male protrusion is received into the female receiving cavity;
- and
- a screw configured to extend through the first and second threaded holes, the screw including a head and a shank, wherein:
- the head includes first threads having a first thread pitch angle;
- the shank includes second threads having a second thread pitch angle;
- and
- the first thread pitch angle is less than the second thread pitch angle.

A prosthesis comprising:
- a neck defining an upper surface and a sidewall extending downward from the upper surface;
- an opening defined by the sidewall and extending into the neck, the opening having an upper portion and a lower portion, wherein the lower portion extends laterally beyond a width of the upper portion;
- further comprising at least one interior surface extending into the neck from the opening to define a female receiving cavity;
- and
- a resection cap configured to be disposed in the female receiving cavity such that the resection cap defines an upper surface that is flush with the upper surface defined by the neck when the resection cap is disposed in the female receiving cavity.
