Abstract
In various embodiments, a surgical plate includes a body extending between a first planar surface and a second planar surface. The body is configured to couple to a first bone. The first planar surface is configured to couple to a first articulation surface. An anterior articulation portion is coupled to the body. The anterior articulation portion includes a third planar surface extending perpendicular to the first and second planar surfaces and a second articulation surface spaced apart from and coupled to the third planar surface. The second articulation surface is configured to articulate with respect to a second bone.
Claims21
A surgical plate, comprising:
- a body extending between a first planar surface and a second planar surface, the body including at least one protrusion projecting outwardly from the second planar surface through at least one fastener hole that communicates between the first planar surface to the second planar surface to engage a first bone while being oriented at an angle relative to the second planar surface, wherein the first planar surface is sized to couple to a first articulation surface of the first bone and extend an entire length of the body;
- and
- an anterior articulation portion extending from the body, the anterior articulation portion including a third planar surface extending perpendicular to the first and second planar surfaces and a second articulation surface that is dome-shaped and extends directly between the first planar surface and the third planar surface, the second articulation surface to articulate with respect to a third bone.
A surgical kit, comprising:
- a surgical plate, including:
- a body extending between a first planar surface and a second planar surface, the body including at least one protrusion projecting outwardly from the second planar surface through at least one fastener hole that communicates between the first planar surface to the second planar surface to engage a first bone while being oriented at one of an acute and an obtuse angle relative to the second planar surface,
- a first articulation surface to articulate with respect to a second bone, wherein the first planar surface extends an entire length of the body to the first articulation surface;
- and
- an anterior articulation portion coupled to the body, the anterior articulation portion including a third planar surface extending perpendicular to the first and second planar surfaces and a second articulation surface extending directly between the first articulation surface and the third planar surface, the second articulation surface to articulate with respect to a third bone;
- and
- a bearing element including a bearing surface to articulate with respect to the second articulation surface of the surgical plate while the bearing element is coupled to the third bone.

A method of resurfacing a bone, comprising:
- resecting an anterior portion of a first bone;
- coupling a surgical plate to the first bone, the surgical plate including a body including at least one protrusion projecting outwardly from a second planar surface through at least one fastener hole that communicates between a first planar surface, which extends an entire length of the body to a first articulation surface, to the second planar surface to engage the first bone while being oriented at least at one of an acute and an obtuse angle relative to the second planar surface, and an anterior articulation portion coupled to the body and including a third planar surface extending perpendicular to the first and second planar surfaces and an anterior articulation surface extending directly between the first planar surface and the third planar surface, wherein the anterior articulation surface articulates with respect to a second bone;
- and
- coupling a posterior articulation surface to the surgical plate.
1 more element
A surgical plate, comprising:
- a body including a first surface spaced apart from a second surface, and at least one post projecting outwardly from the second surface through at least one opening communicating between the first surface to the second surface;
- wherein the at least one opening is oriented through the body to accept the at least one post that is oriented at least at one of an acute and an obtuse angle relative to the second surface to couple the body to a first bone, wherein the first surface is sized to be engaged with a first articulation surface of the first bone and extend an entire length of the body;
- and
- an anterior articulation portion coupled to the body, the anterior articulation portion including a third surface extending perpendicular to the first and second surfaces and a second articulation surface extending directly between the first surface and the third surface, the second articulation surface to articulate with respect to a third bone.
1 more element
A method of resurfacing a bone, comprising:
- resecting an anterior portion of a first bone;
- coupling a surgical plate to the first bone, the surgical plate including:
- a body;
- a first surface spaced apart from a second surface, with at least one post projecting outwardly from the second surface through at least one opening communicating between the first surface to the second surface;
- wherein the at least one opening is oriented through the body to accept the post at an angle relative to the second surface that is at least one of greater than ninety degrees and less than ninety degrees, wherein the first surface is sized to be engaged with a first articulation surface of the first bone and extend an entire length of the body;
- and
- an anterior articulation portion coupled to the body, the anterior articulation portion including a third surface extending perpendicular to the first and second surfaces and a second articulation surface extending directly between the first surface and the third surface, the second articulation surface to articulate with respect to a third bone;
- driving a fastener into the at least one opening to engage the body at an angle relative to the second surface to thereby couple the body to the first bone;
