Elbow prosthesis

摘要

An elbow prosthesis can include a humeral component having a yoke, an ulnar component having a head, a humeral bearing positionable in a base of the humeral component, an ulnar bearing assembly configured to engage with the head, and a pin extendable through the bearing assembly and the head. The pin can be extendable into first and second ears of the yoke to enable pivotable movement of the ulnar component relative to the humeral component. The elbow prosthesis can include a first fastener insertable through the first ear of the yoke and configured to engage with the pin, and a second fastener insertable through the second ear of the yoke and configured to engage with the pin.
