Abstract
Provided herein are methods and systems for stabilizing a joint, such as the elbow. The system may include an intramedullary rod configured to be placed in a medullary canal of a bone, a pin, a linking member defining an aperture for receiving the pin, and a connector defining a first aperture and a second aperture, the first aperture configured to receive the linking member. The system may further include a screw extending through the second aperture of the connector and the aperture of the intramedullary rod. The system may be configured to be implanted into a patient.
Claims20
An internal joint stabilization system comprising:
- an intramedullary rod configured to be placed in a medullary canal of a bone, the intramedullary rod defining an aperture;
- a pin;
- a linking member defining an aperture for receiving the pin;
- a connector defining a first aperture and a second aperture, the first aperture configured to receive the linking member;
- and
- a screw extending through the second aperture of the connector and the aperture of the intramedullary rod.
A method of stabilizing an elbow using a joint stabilization system, the joint stabilization system comprising:
- an intramedullary rod defining an aperture;
- and
- a connector defining a first aperture and a second aperture,
- wherein the method comprises:
- installing the intramedullary rod into an ulna of a patient,
- positioning the connector on the ulna,
- securing the connector to the intramedullary rod by inserting a screw through the second aperture of the connector and the aperture of the intramedullary rod,
- inserting a pin into a humerus and into an axis of rotation of the elbow, wherein the pin is coupled to a linking member, and
- securing the linking member in the first aperture of the connector.
An axis guide configured to find a center of rotation, the axis guide comprising:
- a first arm,
- a second arm, and
- a pivot point connecting the first arm and the second arm,
- wherein the axis guide is made out of a radio lucent material, and
- wherein the first arm and the second arm comprise a radiopaque wire extending along an axis, wherein the axis defined by a line that intersects the pivot point and is parallel to an edge of the first arm and the second arm, respectively.
