Apparatus and method for preparing bone for antirotational implantation of an orthopedic endoprosthesis

A combination of a surgical tool, rotating power tool, and trial component for shaping a bone canal and trialing, comprising:

• a first end for extending into said bone canal, said first end having a longitudinal axis and a cross-section, wherein said cross-section is perpendicular to said longitudinal axis;
• a second end opposite said first end, said second end engaging at least one of said power tool or said trial component;
• and
• a guide disposed between said first and second ends, said guide adapted to facilitate identifying an orientation of said surgical tool on said bone relative to said bone canal, wherein said guide comprises at least two guide channels on said surgical instrument, each of said at least two guide channels having a guide channel axis and a profile that is perpendicular to said guide channel axis, each said guide channel axis being substantially parallel to said longitudinal axis, and each of said profiles intersecting said cross-section of said first end of said surgical tool.

A surgical tool for shaping a bone canal in a bone and rotationally aligning a prosthesis, comprising:

• a first end for extending into said bone canal;
• a second end for extending out of said bone canal;
• at least two guide channels disposed on said second end;
• and
• a cutting instrument adapted to cut said bone, wherein
• said at least two guide channels are configured to receive and direct said cutting instrument for cutting said bone so as to identify said surgical tool's orientation on said bone relative to said bone canal.

A surgical tool for shaping a bone canal in a bone and rotationally aligning a prosthesis, comprising:

• a first end for extending into said bone canal, said first end having at least one bone removing element;
• a second end for extending out of said bone canal, said second end having a mounting element thereon;
• and
• a guide channel disposed on said second end, said guide channel adapted to receive and direct a cutting instrument for cutting said bone so as to identify said surgical tool's orientation on said bone relative to said bone canal;
• wherein said guide channel has a profile and a guide channel axis, and wherein said profile is perpendicular to said guide channel axis, and said guide channel axis is substantially parallel to and offset from a surgical tool axis.

A surgical tool for shaping a bone canal comprising:

• a first end for extending into said bone canal, said first end having a longitudinal axis and a cross-section, wherein said cross-section is perpendicular to said longitudinal axis;
• a second end opposite said first end, said second end having a mating geometry adapted to engage at least one mating part;
• at least one bone removing element for shaping said bone canal located on said first end;
• and
• a guide disposed between said first and second ends, said guide adapted to facilitate identifying an orientation of said surgical tool on said bone relative to said bone canal, wherein said guide comprises at least two guide channels on said surgical tool, each of said at least two guide channels having a guide channel axis and a profile that is perpendicular to said guide channel axis, each said guide channel axis being substantially parallel to said longitudinal axis, and each of said profiles intersecting said cross-section of said first end of said surgical tool.

A surgical tool for shaping a bone canal comprising:

• a first end for extending into said bone canal, said first end having a longitudinal axis and a cross-section, wherein said cross-section is perpendicular to said longitudinal axis;
• a second end opposite said first end, said second end having a mating geometry engaged to a trial component;
• and
• a guide disposed between said first and second ends, said guide adapted to facilitate identifying an orientation of said surgical tool on said bone relative to said bone canal once said orientation is selected via manipulation of said trial component, wherein said guide comprises at least two guide channels on said surgical tool, each of said at least two guide channels having a guide channel axis and a profile that is perpendicular to said guide channel axis, each said guide channel axis being substantially parallel to said longitudinal axis, and each of said profiles intersecting said cross-section of said first end of said surgical tool.

A surgical tool for shaping a bone canal comprising:

• a first end for extending into said bone canal, said first end having a longitudinal axis and a cross-section, wherein said cross-section is perpendicular to said longitudinal axis;
• a second end opposite said first end, said second end having a mating geometry adapted to engage at least one mating part;
• a guide disposed between said first and second ends, said guide adapted to facilitate identifying an orientation of said surgical tool on said bone relative to said bone canal;
• and
• a drill bit used for forming keyways in said bone;
• wherein said guide comprises at least two guide channels that are each adapted to receive said drill bit, each of said at least two guide channels having a guide channel axis and a profile that is perpendicular to said guide channel axis, each said guide channel axis being substantially parallel to said longitudinal axis, and each of said profiles intersecting said cross-section of said first end of said surgical tool.
