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.

1. A system for replacement of at least a portion of a comminuted humeral head, the system comprising: a prosthesis having an exterior surface and at least one aperture formed therein, said exterior surface being sized and shaped to approximate the surface of the at least a portion of the comminuted humeral head;a first plate including a first surface and an opposite second surface, said first surface adapted to contact an exterior portion of a humerus;a second plate including a first surface and an opposite second surface, said first surface including at least one post extending outwardly therefrom, and said second surface being adapted to contact an interior portion of the humerus; andat least one fastener adapted to attach said first and second plates to one another and the humerus, wherein, when the system is position with respect to the humerus, said first plate and said second plate are attached to one another and the humerus with said at least one fastener, and said at least one post extends through the humerus and engages said at least one aperture formed in said prosthesis to connect said prosthesis and said second plate to one another. 2. The system of claim 1, wherein said first surface of said first plate and said second surface of said second plate are adapted to clamp a portion of the humerus therebetween. 3. The system of claim 1, wherein said prosthesis and said first surface of said second plate are adapted to clamp a portion of the humerus therebetween. 4. A system for replacement of at least a portion of a comminuted humeral head, the system comprising: a prosthesis having an exterior surface and at least one aperture formed therein, said exterior surface being sized and shaped to approximate the surface of the at least a portion of the comminuted humeral head;a first plate including a first surface and an opposite second surface, said first surface adapted to contact an exterior portion of a humerus;a second plate including a first surface and an opposite second surface, said first surface including at least one post extending outwardly therefrom, said second surface being adapted to directly contact an interior portion of the humerus, said first surface of said first plate and said second surface of said second plate being adapted to clamp a portion of the humerus therebetween, and said prosthesis and said first surface of said second plate being adapted to clamp a portion of the humerus therebetween; andat least one fastener adapted to attach said first and second plates to one another and the humerus, wherein, when the system is position with respect to the humerus, said first plate and said second plate are attached to one another and the humerus with said at least one fastener, and said at least one post extends through the humerus and engages said at least one aperture formed in said prosthesis to connect said prosthesis and said second plate to one another. 5. The system of claim 4, wherein said second plate includes a central longitudinal axis extending through said second plate and said at least one post, said second plate having a first maximum cross-sectional dimension perpendicular to the central longitudinal axis, and said at least one post having a second maximum cross-sectional dimension perpendicular to the central longitudinal axis, the second maximum cross-sectional dimension being less than half of the first maximum cross-sectional dimension. 6. The system of claim 4, wherein said first surface of said second plate is substantially oriented in a first direction and said second surface of said second plate is substantially oriented in a second direction, the first and second directions being opposite to one another. 7. The system of claim 4, wherein said at least one post includes a first end and a second end, said at least one post being attached to the remainder of said second plate at said first end, and said at least one post tapers from said first end toward said second end. 8. The system of claim 7, wherein said second plate includes a central longitudinal axis extending through said second plate and said at least one post, said second plate having a maximum cross-sectional dimension perpendicular to said central longitudinal axis, said first surface of said second plate tapering toward said at least one post from adjacent the first maximum cross-sectional dimension. 9. A system for replacement of at least a portion of a comminuted humeral head, the system comprising: a prosthesis having an exterior surface and at least one aperture formed therein, said exterior surface being sized and shaped to approximate the surface of the at least a portion of the comminuted humeral head;a first plate including a first surface and an opposite second surface, said first surface adapted to contact an exterior portion of a humerus;a second plate including a first surface and an opposite second surface, said first surface of said second plate being substantially oriented in a first direction, said second surface of said second plate being substantially oriented in a second direction, the first and second directions being opposite to one another, said first surface including at least one post extending outwardly therefrom, said second surface being adapted to directly contact an interior portion of the humerus, said second plate including a central longitudinal axis extending through said second plate and said at least one post, said second plate having a first maximum cross-sectional dimension perpendicular to the central longitudinal axis, and said at least one post having a second maximum cross-sectional dimension perpendicular to the central longitudinal axis, the second maximum cross-sectional dimension being less than half of the first maximum cross-sectional dimension; andat least one fastener adapted to attach said first and second plates to one another and the humerus, wherein, when the system is position with respect to the humerus, said first plate and said second plate are attached to one another and the humerus with said at least one fastener, and said at least one post extends through the humerus and engages said at least one aperture formed in said prosthesis to connect said prosthesis and said second plate to one another.
