Abstract
Embodiments of the invention include a system for coupling a graft to a bone. A graft preparation tool may be used to place one or more holes in a graft and an offset measurement tool may be used to determine the distance of the one or more holes from an edge of the graft to be aligned with a portion of the bone. One or more complementary holes may then be created in the bone and fasteners applied through the holes to couple the graft to the bone.
Claims26
A system for coupling a graft to a bone comprising:
- an offset measurement tool comprising:
- a body,
- a pin with a cross-sectional center axis, the pin coupled to the body, wherein the pin is sized to fit within a hole in the graft, and
- two or more legs coupled to the body and extending to two or more different distances from the cross-sectional center axis of the pin;
- and
- a set of two or more offset drill guides, at least two of the drill guides comprising:
- a drill positioning opening, and
- an alignment surface having a spacing from a respective drill positioning opening, wherein two or more of the offset drill guides in the set of two or more offset drill guides include respective spacings that are coordinated with respective offsets that may be measured using respective legs that extend respective distances, the measuring legs being chosen from the two or more legs of the offset measurement tool.
A system for coupling a graft to a bone comprising:
- an offset measurement tool comprising:
- a body,
- a pin with a cross-sectional center axis, the pin coupled to the body, wherein the pin is sized to fit within a hole in the graft, and
- two or more legs coupled to the body and extending to two or more different distances from the cross-sectional center axis of the pin;
- and
- means for guiding drilling of respective holes in a graft at a spacing coordinated with an offset that may be measured using a leg of the two or more legs of the offset measurement tool.
A system for coupling a graft to a bone comprising:
- a graft preparation tool comprising:
- a holder in which a graft may be positioned, and
- a drilling alignment mechanism configured to guide placement of one or more holes in a graft;
- an offset measurement tool comprising:
- a body,
- a pin with a cross-sectional center axis, the pin coupled to the body, wherein the pin is sized to fit within at least one of the one or more holes in the graft, and
- two or more legs coupled to the body and extending to two or more different distances from the cross-sectional center axis of the pin;
- and
- an offset drill guide comprising:
- a drill positioning opening, and
- an alignment surface set a distance from the drill positioning opening, wherein the distance set from the drill positioning opening is coordinated with the offset measured with the offset measurement tool.
