Abstract
A bone plate is provided including a plate member including a through-hole; a disk provided in the through-hole and rotatabiy supported in the plate member, the disk including a slot that is shaped such as to allow a guided displacement of the bone plate in a plane perpendicular to an axis of rotation of the disk with respect to a bone anchor extending through the slot.
Claims29
A hone plate comprising:
- a plate member including a top side, a bottom side, and a through-hole extending through the top side and the bottom side;
- and
- a disk, wherein the disk is receivable in the through-hole to be rotatably supported in the plate member about an axis of rotation extending from the top side to the bottom side,
- the disk including a slot configured to receive a bone anchor therethrough, the slot having a non-circular shape when viewed along the axis of rotation to allow a guided displacement of the bone plate in a plane perpendicular to the axis of rotation,
- wherein the disk is receivable in the through-hole along a direction of the axis of rotation and, is rotatable in the through-hole from a first position to a second position wherein the disk is configured to be held against removal from the through-hole along both directions of the axis of rotation when in the second position.
A bone plate comprising:
- a plate member including a top side, a bottom side, and through-hole extending through the top side and the bottom side;
- and
- a disk, wherein the disk is provided in the through-hole and rotatably supported in the plate member about an axis of rotation extending from the top side to the bottom side,
- the disk including a slot configured to receive a bone anchor theretrough, the slot having a non-circular shape when viewed along the axis of rotation to allow a guided displacement of the bone plate in a plane perpendicular to the axis of rotation.
A bone plate assembly comprising:
- a bone plate comprising:
- a plate member including a top side, a bottom side, and a through-hole extending through the top side and the bottom side;
- and
- a disk, wherein the disk is receivable in the through-hole to be rotatably supported in the plate member about an axis of rotation extending from the top side to the bottom side, the disk including a slot,
- wherein the disk is receivable in the through-hole along a direction of the axis of rotation and is rotatable in the through-hole from a first position to a second position wherein the disk is configured to be held against removal from the through-hole along both directions of the axis of rotation when in the second position;
- and
- a bone anchor insertable in the slot of the disk, wherein the slot of he disk and the bone anchor are adapted to each other such as to allow a guided displacement of the bone plate in a plane perpendicular to the axis of rotation with respect to the bone anchor when the bone anchor is inserted in the slot.
A method of using a hone plate, the bone plate including a plate member including, a through-hole, and a disk, wherein the disk is receivable in the through-hole to be rotatably supported in the plate member, the disk including a slot having a shape configured to receive a bone anchor and to allow a guided displacement of the bone plate in plane perpendicular to an axis of rotation of the disk with respect to the bone anchor, the method comprising:
- placing the bone plate on a bone or a bone part;
- inserting the bone anchor through the slot;
- fixing the bone anchor to the bone or the bone part;
- and
- rotating the disk in the through-hole about the axis of rotation.
