Systems and Methods for Joint Stabilization

摘要

Photodynamic devices for stabilizing a joint are provided. In some embodiments, a photodynamic joint spacer is provided that includes an expandable member configured for attachment to a bone having an excised region; a formable bar configured for attachment to the bone along at least a portion of the expandable member; and a light-sensitive liquid passed into the expandable member to expand the expandable member, wherein the expandable member is shaped by the formable bar to a shape resembling the excised region of the bone, and wherein the light-sensitive liquid is curable upon exposure to light energy to set the expandable member in the shape resembling the excised region to form a photodynamic joint spacer.

主权项

1. A method for stabilizing an articular joint comprising:
attaching a formable bar to a bone in proximity to an excised region; disposing an expandable member adjacent to the formable bar; shaping, with the formable bar, the expandable member to approximate an anatomical angle of the excised region of the bone; expanding the expandable member with a light-sensitive liquid; and curing the light-sensitive liquid within the expandable member to create a photodynamic joint spacer having the anatomical angle of the excised region of the bone to stabilize the joint.
