Abstract

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.

Claims

1. An articular bone repair device comprising:

an inflatable support member; and

an articular member having an articular part, a bearing surface disposed on the articular part, and an attachment part configured to complementarily engage the inflatable support member,

wherein the inflatable support member is inflatable and deflatable to adjust at least one of a position, an angulation, an alignment of the articular member relative to the inflatable support member,

wherein the inflatable support member is sufficiently designed to reside within a cavity of a bone to anchor the articular member inside the cavity.

2. The articular bone repair device of claim 1, wherein the articular member is fixedly attached to the inflatable support member.

3. The articular bone repair device of claim 1, wherein the articular member is removably attached to the inflatable support member.

4. The articular bone repair device of claim 1, further comprising a recess in the articular member, the recess designed to receive the inflatable support member.

5. The articular bone repair device of claim 1, wherein the articular member has a shaft and the inflatable support member includes an opening into which the shaft of the articular member can be inserted to attach the articular member to the inflatable support member.

6. The articular bone repair device of claim 1, wherein the articular member has at least a portion that is cylindrical, tubular, rounded or ball-shaped.

7. The articular 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.

8. The articular bone repair device of claim 1, wherein the bearing surface concave.

9. The articular bone repair device of claim 1, wherein the inflatable support member is configured to complementarily engage the articular member, and the bearing surface is configured to enter into an articular engagement with an articular head of a bone opposing the bone to be repaired.

10. The articular bone repair device of claim 1, wherein the inflatable support member is sufficiently designed to reside within a cavity of a bone to anchor the articular member inside the cavity.

11. The articular bone repair device of claim 1, wherein the bearing surface is concave and disposed on the articular part.

12. The articular bone repair device of claim 1, wherein the articular member is fixedly attached to the inflatable support member.

13. The articular bone repair device of claim 1, wherein the articular member is removably attached to the inflatable support member.
