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 carpal articular surface of a radius, the system comprising: a prosthesis having a plate-like portion and at least one portion, said plate-like portion having an exterior surface formed thereon, and said at least one portion being positioned opposite from said exterior surface and being adapted to directly contact an interior portion of the radius, said at least one portion having at least one aperture provided therein, said exterior surface being sized and shaped to approximate the surface of the at least a portion of the carpal articular surface of the radius, and said at least one aperture of said at least one a portion of said prosthesis being adapted to receive at least one fastener therein;a bone plate having a first end an opposite second end, and a length and a longitudinal axis extending between said first end and said second end, said bone plate having a width perpendicular to the length of said bone plate, said bone plate having an upper surface, a lower surface, and a thickness extending between said upper surface and said lower surface, said lower surface being adapted to contact an exterior of the radius, said bone plate having at least one opening passing from said upper surface through said lower surface and being configured to receive said at least one fastener therethrough, at least a portion of said bone plate being configured to be attached to the radius proximate of the distal end thereof, said bone plate and said at least one portion of said prosthesis being spaced from one another when said system is assembled and being adapted to clamp a portion of the radius between said lower surface of said bone plate and said at least one portion of said prosthesis via said at least one fastener drawing said bone plate and said at least one portion of said prosthesis toward one another; andsaid at least one fastener having a first end for insertion through said at least one opening and into said at least one aperture, said at least one fastener being configured to secure attachment of said prosthesis and said bone plate to one another across a portion of the radius. 2. The system of claim 1, wherein said at least one portion comprises at least a first protuberance extending outwardly from said plate-like portion, said at least a first protuberance being adapted to contact the interior portion of the radius. 3. The system of claim 1, wherein, when the system is positioned with respect to the radius, said plate-like portion has a first edge oriented toward a volar rim of the carpal articular surface and a second edge opposite said first edge oriented toward a dorsal rim of the carpal articular surface, said first edge and said second edge of said plate-like portion being between said dorsal rim and said volar rim of the carpal articular surface. 4. The system of claim 1, wherein, when the system is positioned with respect to the radius, said plate-like portion has a first edge oriented toward a volar rim of the carpal articular surface and a second edge opposite said first edge oriented toward a dorsal rim of the carpal articular surface, said first edge and said second edge of said plate-like portion extending from said dorsal rim and said volar rim of the carpal articular surface. 5. The system of claim 1 wherein said bone plate has a first portion proximate said first end of said bone plate and a second portion proximate said second end of said bone plate, said first portion having at least one aperture extending between said upper surface and said lower surface, said at least one aperture being adapted to receive a bone screw to engage said bone plate to said radius, said at least one opening of said bone plate extending between said upper surface and said lower surface of said second portion and being configured to receive said at least one fastener therethrough. 6. The system of claim 1, wherein said at least one portion of said prosthesis extends generally perpendicular from said plate-like portion and into the radius, said at least one a portion being a protuberance, said protuberance including two apertures each adapted to receive at least one fastener therein. 7. The system of claim 1, wherein said at least one portion of said prosthesis includes two portions spaced from one another and each extending generally perpendicular from said late-like portion and into the radius said two portions each being a protuberance, each of said two protuberances including at least one aperture adapted to receive at least one fastener therein. 8. The system of claim 7, wherein each of said two protuberances includes two apertures, each of said two apertures being adapted to receive at least one fastener therein. 9. The system of claim 7, wherein each of said two protuberances are oriented generally perpendicular to said lower surface of said bone plate. 10. The system of claim 1, wherein said exterior surface of said plate-like portion of said a prosthesis is contoured for cooperative engagement with portions of a wrist including a lunate and a scaphoid.
