US 2015/0088263 A1 · ELBOW PROSTHESIS

Abstract

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.

An elbow prosthesis comprising:

a humeral component comprising a humeral stem and a yoke having first and second ears, each ear having a first opening and a second opening;
an ulnar component comprising an ulnar stem and an ulnar head;
a pin extendable through the ulnar head and securable to the humeral component such that the ulnar head pivots about the pin to enable movement of the ulnar component relative to the humeral component, a first end portion of the pin positionable in the first opening of the first ear of the yoke and a second end portion of the pin positionable in the first opening of the second ear of the yoke;
a first fastener securable in the second opening of the first ear of the yoke, the first fastener including a threaded portion for threaded engagement with the second opening of the first ear and a non-threaded portion for contact with the first end portion of the pin;
and
a second fastener securable in the second opening of the second ear of the yoke, the second fastener including a threaded portion for threaded engagement with the second opening of the second ear and a non-threaded portion for contact with the second end portion of the pin.

An elbow prosthesis comprising:

a humeral component comprising a humeral stem and a yoke having first and second ears extending from a base of the yoke, each ear having a pin opening and a fastener opening;
an ulnar component comprising an ulnar stem and an ulnar head;
a pin extendable through the ulnar head and into the pin opening of each of the first and second ears such that the ulnar head pivots about the pin to enable movement of the ulnar component relative to the humeral component;
one or more bearing components attachable to the humeral component and configured such that the ulnar head articles against a surface of the one or more bearings when the ulnar component moves relative to the humeral component;
a first fastener configured to be inserted into the fastener opening of the first ear and contact the pin;
and
a second fastener configured to be inserted into the fastener opening of the second ear and contact the pin.
