The system and method serves in 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 method for replacing at least a portion of a comminuted humeral head of a humerus, the method comprising: utilizing a prosthesis having an exterior portion having an exterior surface, and an interior portion having at least one first aperture and at least one second aperture formed therein, the
1. A method for replacing at least a portion of a comminuted humeral head of a humerus, the method comprising: utilizing a prosthesis having an exterior portion having an exterior surface, and an interior portion having at least one first aperture and at least one second aperture formed therein, the exterior surface approximating the surface of the at least a portion of the comminuted humeral head in size and shape;utilizing a bone plate, said bone plate including an upper portion adapted to attach to the humerus at a position proximate a surgical neck thereof, and an elongated lower portion adapted to attach to a shaft of the humerus, said upper portion including at least one first opening and at least one second opening formed therein, the at least one first opening and the at least one second opening of said upper portion of said bone plate being configured to receive at least one first fastener and at least one second fastener, respectively, therethrough, said elongated lower portion of said bone plate including at least one third opening formed therein, the at least one third opening of said elongated lower portion of said bone plate being configured to receive at least one third fastener therethrough;removing at least a portion of the comminuted humeral head;aligning the at least one first aperture of said prosthesis with the at least one first opening of said upper portion of said bone plate and aligning the at least one second aperture of said prosthesis with the at least one second opening of said upper portion of said bone plate;inserting the at least one first fastener through the at least one first opening in said upper portion of said bone plate and into the at least one first aperture in said prosthesis and inserting the at least one second fastener through the at least one second opening in said upper portion of said bone plate and into the at least one second aperture in said prosthesis; andinserting the at least one third fastener through the at least one third opening in the elongated lower portion of said bone plate and into the shaft of the humerus, thereby securing attachment of said prosthesis and said bone plate to one another and to the humerus, using the at least one first, second, and third fasteners. 2. The method of claim 1, wherein the removing further comprises removing portions of the comminuted humeral head that are irretrievably fragmented. 3. The method of claim 1, wherein said bone plate is attached to a side of the humerus opposite from the position of the comminuted humeral head. 4. The method of claim 1, wherein the securing attachment further comprises securing said prosthesis and said bone plate in fixed position relative to the humerus. 5. The method of claim 1, wherein at least a portion of the exterior surface is convex, and the interior portion includes an interior surface, at least a portion of the interior surface being concave. 6. The method of claim 1, wherein the interior portion of said prosthesis includes a plurality of posts, wherein at least one of the plurality of posts includes an axially-extending aperture defined therein. 7. The method of claim 1, further comprising utilizing an extension portion extending outwardly from said prosthesis, inserting the extension portion in a medullary cavity of the humerus, and attaching the extension portion to the humerus. 8. The method of claim 6, further comprising inserting at least one fourth fastener through at least one fourth opening in the upper portion of said bone plate into the at least one axially-extending aperture defined in the at least one of the plurality of posts. 9. The method of claim 7, further comprising inserting at least one fourth fastener through at least one fourth opening in the elongated lower portion of said bone plate, through the shaft of the humerus, and into at least one opening defined in said extension portion. 10. A method for replacing at least a portion of a comminuted humeral head of a humerus, the method comprising: utilizing a prosthesis having an exterior portion, the exterior portion having an exterior surface, and an interior portion, the interior portion having at least one first aperture and at least one second aperture formed therein, the exterior surface approximating the surface of at least a portion of the comminuted humeral head in size and shape;utilizing a bone plate, said bone plate including an upper portion adapted to attach to the humerus at a position proximate a surgical neck thereof, and a lower portion adapted to attach to a shaft of the humerus;removing at least a portion of the comminuted humeral head;aligning at least one first opening in said upper portion of said bone plate with the at least one first aperture formed in the interior portion of said prosthesis, and aligning at least one second opening in said upper portion of said bone plate with the at least one second aperture formed in the interior portion of said prosthesis;inserting at least one first fastener through the at least one first opening in said upper portion of said bone plate and into the at least one first aperture formed in the interior portion of said prosthesis, and inserting at least one second fastener through the at least one second opening in said upper portion of said bone plate and into the at least one second aperture formed in the interior portion of said prosthesis; andinserting at least one third fastener through at least one third opening defined in the lower portion of said bone plate and into the shaft of the humerus, thereby securing attachment of said prosthesis and said bone plate to one another and to the humerus, using the at least one first, second, and third fasteners. 11. The method of claim 10 further comprising utilizing an extension portion extending outwardly from the said prosthesis, and inserting said extension portion in a medullary cavity of the humerus. 12. The method of claim 11, further comprising inserting at least one fourth fastener through at least one fourth opening defined in the lower portion of said bone plate, through the shaft of the humerus and into at least one aperture defined in said extension portion.
