    摘要: An elbow prosthesis according to the present teachings can include a stem structure and an articulating component. The stem structure can be operable to be positioned in a bone of a joint. The stem structure can include a stem portion that is operable to be positioned in the bone and a C-shaped body portion having a first retaining mechanism formed thereon. The articulating component can have a second retaining mechanism formed thereon. One of the first and second retaining mechanisms can comprise an extension portion and a first anti-rotation portion. The other retaining mechanism can comprise a receiving portion and a second anti-rotation portion. The articulating component can be advanced from an insertion position to an assembled position, such that the first and second mechanisms cooperatively interlock to inhibit translation and rotation of the articulating component relative to the C-shaped body portion of the stem structure.

    摘要: An elbow prosthesis constructed in accordance to one example of the present teachings can include a first stem structure that is operable to be positioned in a first bone of a joint. The first stem structure can include a first stem portion and a cage structure. The first stem portion may be operable to be positioned in the first bone. The cage structure can be formed generally between an inner sidewall and an outer surface. The stem portion can have opposing surfaces that define a disconnect formed entirely through the cage structure from the inner sidewall to the outer surface. A first bearing component can have an exterior cage opposing surface. The first bearing component can be selectively inserted into the cage structure from an insertion position to an installed position. A fastener can be threadably advanced into an engaged position with the cage structure to reduce a gap defined between the opposing surfaces of the disconnect while radially contracting the cage structure around the first bearing.
