1. A bone graft distribution apparatus comprising:
a hollow tube constructed to receive bone graft, said hollow tube having a length, an extended axis and a proximal end and a distal end, said hollow tube having a uniform interior cross-section from said proximal end to said distal end; a substantially hollow implant detachably interconnected to the distal end of the hollow tube, said implant constructed to receive bone graft from said hollow tube, said implant having at least two openings having an upper and a lower end located on opposite lateral sides of said implant, said implant having a proximal end and a tapered distal end, said tapered distal end spanning the extended axis and forming the most distal end of the bone graft distribution apparatus, the implant proximal end forming a perimeter which engages the hollow tube distal end; and a plunger adapted for inserting into said proximal end of said hollow tube along the extended axis, said plunger having a distal end exterior surface of cross-section contoured to said interior cross-section of said hollow tube, said plunger distal end exterior surface of cross-section forming a substantially congruent fit with said hollow tube uniform interior cross-section, said plunger having an axial length at least sufficient to extend to the length of the hollow tube; wherein said hollow tube, said substantially hollow implant and said plunger are configured to deliver bone graft material into the interior of the substantially hollow implant and through the at least two openings of said substantially hollow implant when the plunger is advanced from the proximal end to the distal end of the hollow tube along the extended axis, wherein the distal end of said plunger is configured to remain always proximal to the tapered distal end of said substantially hollow implant when said plunger is inserted into said hollow tube and said substantially hollow implant is attached to said hollow tube. |
