Abstract
An osteotomy plate for maintaining the spacing of a wedge-like opening in bone, the osteotomy plate comprising: a body having a front side and a back side; a protrusion extending out of the back side of the body for disposition in the wedge-like opening; and a plurality of mounting holes for receiving fixation screws therein, the mounting holes being formed in the body such that when the protrusion is disposed in the wedge-like opening, the mounting holes direct the fixation screws into bone on either side of the wedge-like opening.
Claims25
An osteotomy plate for maintaining the spacing of a wedge-like opening in bone, the osteotomy plate comprising:
- a body having a front side and a back side;
- a protrusion extending out of the back side of the body for disposition in the wedge-like opening;
- and
- a plurality of mounting holes for receiving fixation screws therein, the mounting holes being formed in the body such that when the protrusion is disposed in the wedge-like opening, the mounting holes direct the fixation screws into bone on either side of the wedge-like opening.
An osteotomy system comprising:
- a wedge-shaped implant for disposition in a wedge-like opening in bone;
- and
- an osteotomy plate for securing the wedge-shaped implant in the wedge-like opening, the osteotomy plate comprising:
- a body having a front side and a back side;
- and
- a plurality of mounting holes for receiving fixation screws therein, the mounting holes being formed in the body such that when the body is disposed across the opening of the wedge-like opening, the mounting holes direct the fixation screws into bone on either side of the wedge-like opening, whereby the body of the osteotomy plate may secure the wedge-shaped implant in the wedge-like opening.
A method for performing an osteotomy, the method comprising:
- forming an osteotomy cut in the bone;
- opening the bone so as to form a wedge-like opening;
- providing an osteotomy plate, wherein the osteotomy plate comprises:
- a body having a front side and a back side;
- a protrusion extending out of the back side of the body for disposition in the wedge-like opening;
- and
- a plurality of mounting holes for receiving fixation screws therein, the mounting holes being formed in the body such that when the protrusion is disposed in the wedge-like opening, the mounting holes direct fixation screws into the bone on either side of the wedge-like opening;
- positioning the osteotomy plate so that the back side of the osteotomy plate is positioned against the bone and the protrusion is disposed in the wedge-like opening;
- and
- passing fixation screws through the mounting holes formed in the osteotomy plate and into the bone so as to secure the osteotomy plate to the bone.
A method for performing an osteotomy, the method comprising:
- forming an osteotomy cut in the bone;
- opening the bone so as to form a wedge-like opening;
- providing an osteotomy system comprising:
- a wedge-shaped implant for disposition in a wedge-like opening in bone;
- and
- an osteotomy plate for securing the wedge-shaped implant in the wedge-like opening, the osteotomy plate comprising:
- a body having a front side and a back side;
- and
- a plurality of mounting holes for receiving fixation screws therein, the mounting holes being formed in the body such that when the body is disposed across the opening of the wedge-like opening, the mounting holes direct the fixation screws into bone on either side of the wedge-like opening;
- positioning the wedge-shaped implant in the wedge-like opening in bone;
- positioning the osteotomy plate so that the back side of the osteotomy plate is positioned against the bone, whereby the body of the osteotomy plate may secure the wedge-shaped implant in the wedge-like opening;
- and
- passing fixation screws through the mounting holes formed in the osteotomy plate and into the bone so as to secure the osteotomy plate to the bone.
