Photodynamic articular joint implants and methods of use
Photodynamic devices for replacement of an articular head of a bone are provided. In an embodiment, a photodynamic device includes a photodynamic support member and an articular member attachable, either fixedly or removably, to the photodynamic support member and having a bearing surface. In an embodiment, the articular member includes a recess designed to receive the photodynamic support member. In an embodiment, the photodynamic support member includes an opening into which a shaft of the articular member can be inserted to attach the articular member to the photodynamic support member.
1. A bone repair device comprising:
an inflatable support member; and
an articular member having an elongate shaft configured to attach to the inflatable support member, and a bearing surface;
wherein the inflatable support member includes an elongate opening that is designed to receive the elongate shaft of the articular member, the inflatable support member being inflatable and deflatable to adjust at least one of a position, an angulation, and an alignment of the articular member relative to the inflatable support member when the elongate shaft is positioned within the elongate opening of the inflatable support member.
2. The bone repair device of claim 1 , wherein the articular member is fixedly attached to the inflatable support member.
3. The bone repair device of claim 1 , wherein the articular member is removably attached to the inflatable support member.
4. The bone repair device of claim 1 , wherein the bearing surface is configured to enter into an articular engagement with an articular head of a bone opposing the bone to be repaired.
5. The bone repair device of claim 1 , wherein the articular member is configured to approximate dimensions and size of an articular head of a bone being repaired using the bone repair device.
6. The bone repair device of claim 1 , wherein the inflatable support member is configured to reside within a cavity of a bone to anchor the articular member inside the cavity.
7. The bone repair device of claim 1 , further comprising a second inflatable support member and a second articular member configured to be used in conjunction with the inflatable support member and the articular member.
8. The bone repair device of claim 7 , wherein the inflatable support member and the second inflatable support member are configured to be positioned in a space within bone.
9. The bone repair device of claim 7 , wherein the bearing surface of the articular member is configured to engage with a bearing surface of the second articular member.
10. A bone repair device comprising:
an inflatable support member; and
an articular member having a recess configured to attach to the inflatable support member, the recess having a shape that corresponds to a shape of an end of the inflatable support member, and a bearing surface;
wherein attachment of the inflatable support member and the articular member allows for adjustment of an angle of the articular member relative to the inflatable support member, and
wherein the inflatable support member being inflatable and deflatable to adjust at least one of a position, an angulation, and an alignment of the articular member relative to the inflatable support member when the articular member is attached to inflatable support member.
11. The bone repair device of claim 10 , wherein the articular member is fixedly attached to the inflatable support member.
12. The bone repair device of claim 10 , wherein the articular member is removably attached to the inflatable support member.
13. The bone repair device of claim 10 , wherein the articular member is adjusted relative to a central axis of the inflatable support member.
14. The bone repair device of claim 10 , wherein a height of the bone repair device is configured to be adjusted by adjusting a depth of engagement between the inflatable support member and the articular member.
15. The bone repair device of claim 10 , further comprising a second inflatable support member and a second articular member configured to be used in conjunction with the inflatable support member and the articular member.
16. The bone repair device of claim 10 , wherein the inflatable support member is configured to reside within a cavity of a bone to anchor the articular member inside the cavity.
