Abstract
A system and method facilitating replacement of comminuted bone fractures or portions thereof adjacent bone joints. The system and method employs a prosthesis to replace at least a portion of the comminuted bone fractures. The prosthesis serves in reproducing the articular surface of the portion or portions of the comminuted bone fractures that are replaced. In doing so, the prosthesis serves in restoring joint viability and corresponding articulation thereof.
Claims20
A system for replacement of at least a portion of a humeral head of a humerus, the system comprising:
- a bone plate having a plate portion and a post portion, the plate portion including a first surface and an opposite second surface, the post portion extending outwardly from the second surface, and the second surface being configured to contact the humerus opposite from the humeral head;
- and
- a prosthesis having an exterior surface, an opposite interior surface, a rim portion, and a column portion, the exterior surface being sized and shaped to approximate the surface of the at least a portion of the humeral head, at least one of the exterior surface and the interior surface terminating at the rim portion, and the column portion having a first end, an opposite second end, and a mid-longitudinal axis extending through the first end and the second end, the column portion being attached at the first end to the interior surface, the column portion extending outwardly from the interior surface from the first end to the second end thereof, and the column portion including an aperture formed therein at and adjacent the second end thereof;
- wherein the aperture is configured to receive a portion of the post portion to connect the prosthesis and the bone plate to one another;
- and
- wherein a first plane extends along the mid-longitudinal axis of the column portion, a second plane perpendicular to the first plane extends from one side of the rim portion to another side of the rim portion, and the column portion terminates at the second end thereof adjacent the second plane.
A system for replacement of at least a portion of a humeral head of a humerus, the system comprising:
- a bone plate having a plate portion and a post portion, the plate portion including a first surface and an opposite second surface, the post portion extending outwardly from the second surface, the second surface being configured to contact the humerus opposite from the humeral head, and a first portion of the post portion being adapted to extend through the humerus when the second surface is contacted to the humerus;
- and
- a prosthesis having an exterior surface, an opposite interior surface, a rim portion, and a column portion, the exterior surface being sized and shaped to approximate the surface of the at least a portion of the humeral head, and the column portion having a first end, an opposite second end, and a mid-longitudinal axis extending through the first end and the second end, the column portion being attached at the first end to the interior surface, the column portion extending outwardly from the interior surface from the first end to the second end thereof, and the column portion including an aperture formed therein at and adjacent the second end thereof;
- wherein, when the system is positioned with respect to the humerus, the first portion of the post portion extends through the humerus and a second portion of the post portion engages the aperture formed in the column portion to connect the prosthesis and the bone plate to one another;
- and
- wherein a first plane extends along the mid-longitudinal axis of the column portion, a second plane perpendicular to the first plane extends from one side of the rim portion to another side of the rim portion, and the column portion terminates at the second end thereof adjacent the second plane.
A system for replacement of at least a portion of a humeral head of a humerus, the system comprising:
- a bone plate having a plate portion and a post portion, the plate portion including a first surface and an opposite second surface, the post portion extending outwardly from the second surface, the second surface being configured to contact the humerus opposite from the humeral head, and a first portion of the post portion being adapted to extend through the humerus when the second surface is contacted to the humerus;
- and
- a prosthesis having an exterior surface, an opposite interior surface, a rim portion, and a column portion, the exterior surface being sized and shaped to approximate the surface of the at least a portion of the humeral head, and the column portion having a first end, an opposite second end, and a mid-longitudinal axis extending through the first end and the second end, the column portion being attached at the first end to the interior surface, the column portion extending outwardly from the interior surface from the first end to the second end thereof, and the column portion including an aperture formed therein at and adjacent the second end thereof;
- wherein the prosthesis and the first surface are adapted to clamp a portion of the humerus therebetween;
- wherein, when the system is positioned with respect to the humerus, the post portion engages the aperture formed in the column portion to connect the prosthesis and the bone plate to one another;
- and
- wherein a first plane extends along the mid-longitudinal axis of the column portion, a second plane perpendicular to the first plane extends from one side of the rim portion to another side of the rim portion, and the column portion terminates at the second end thereof adjacent the second plane.
