Abstract
A system includes an intraosseous sliding osteotomy (ISO) plate including a body extending between a first end, a second end, a first surface, a second surface, and a perimeter wall. The body defines at least one fastener aperture extending from the first surface to the second surface. A plate handle is configured to be coupled to the ISO plate. The plate handle includes a body including a handle portion and a head portion. The head portion defines at least one aperture. A locking element includes a locking portion sized and configured to extend through the at least one aperture defined in the head portion of the plate handle to couple the plate handle to the ISO plate.
Claims25
A system, comprising:
- an intraosseous sliding osteotomy (ISO) plate including:
- a body extending between a first surface and a second surface and defined by a perimeter wall;
- an insertion portion defining a portion of the body that is sized and configured to insert into a medullary canal of a bone, the insertion portion including a tapered portion having a width extending between the perimeter wall that increases from the first end to a first position in the body;
- a compression portion including a non-locking fastener aperture that extends through the body at a predetermined angle;
- a fixation portion extending from a second position in the body to the second end and including a plurality of fastener apertures adjacent to each other laterally across a width of the body and extending from the first surface to the second surface;
- and
- a plate handle configured to be coupled to the ISO plate and including a handle head positioned at a distal end of a handle body, wherein the handle head includes an opening configured to receive at least one locking drill guide and defined by a first circular portion, a second circular portion, and a channel extending from the first and the second circular portions to a distal edge of the handle body.
A method of forming an osteotomy, comprising:
- cutting a bone to define a first bone portion and a second bone portion;
- inserting a broach partially into a cut in the bone;
- rotating the broach to displace the first bone portion from the second bone portion;
- partially inserting an intraosseous sliding osteotomy (ISO) plate having a tapered leading edge into the second bone portion;
- forming a first fastener channel in the first bone portion using a drill guide including a drill guide insert positioned within a head portion of the drill guide by inserting the drill guide insert into a first locking aperture of the ISO plate and drilling through the drill guide insert;
- inserting a first locking fastener through the first locking aperture and into the first fastener channel;
- forming a second fastener channel in the second bone portion using the drill guide insert by inserting the drill guide insert into a non-locking aperture of the ISO plate and drilling through the drill guide insert;
- and
- inserting a non-locking fastener through the non-locking aperture and into the second fastener channel.
A system, comprising:
- an intraosseous sliding osteotomy (ISO) plate including a non-locking fastener aperture that extends through the body at a predetermined angle, a fixation portion extending from a second position in the body to the second end and including a plurality of fastener apertures adjacent to each other laterally across a width of the body and extending from the first surface to the second surface;
- and
- a drill guide including a head portion including a neck extending from a handle portion and an insert receiving portion sized and configured to be inserted into any one of the non-locking fastener aperture and fastener apertures of the ISO plate, wherein
- the neck includes an offset portion that extends a predetermined distance to position the insert receiving portion at a predetermined vertical offset from the handle portion, and
- the insert receiving portion includes a body defining an insert channel extending therethrough and configured to receive a drill guide insert therein.
