Abstract:
1. A bone graft insertion apparatus comprising: a hollow tube constructed to receive bone graft, said hollow tube having an extended axis and a proximal end and a distal end, said hollow tube having a rectangular interior cross-section from said proximal end to said distal end, said distal end having a substantially tapered distal tip interior surface and a distal end interior surface of rectangular cross-section, said hollow tube of single-piece construction; a plunger adapted for inserting into said proximal end of said hollow tube, said plunger having a distal end exterior surface of rectangular cross-section contoured to said distal end interior surface of said hollow tube, said plunger of single-piece construction, said plunger distal end exterior surface of rectangular cross-section forming a substantially congruent fit with said hollow tube rectangular interior cross-section, said plunger having a substantially tapered distal tip contoured to said substantially tapered distal tip interior surface of said hollow tube to form a substantially congruent fit, wherein said hollow tube and said plunger are configured to deliver bone graft material to a graft receiving area through one or more lateral openings near said distal end of said hollow tube, said plunger having an axial length at least sufficient wherein at a least a portion of said plunger distal end is positioned adjacent to said one or more lateral openings when fully inserted into said hollow tube, said one or more lateral openings substantially precluding the delivery of bone graft material directly along said axis of said hollow tube, said plunger precluded from rotating when inserted into said hollow tube.
