Abstract
The present invention is directed to a hinge joint implant (40) configured to fit in a joint cavity and which can comprise, when in situ, an at least hemi-spherocylindrical configuration, and further a hinge joint implant configured to fit in a joint cavity wherein the implant can extend around the sides of a joint component which may be a bone and/or cartilage. The invention further provides the use of a hinge joint implant according for treating arthritis, and/or torn cartilage, and a method for manufacturing a hinge joint implant from one or more pieces.
Claims18
A hinge joint implant for an articulating two-component hinge joint, the implant comprising:
- i) a sac formed of deformable material and comprising an outer layer;
- and
- ii) a filler inside the sac;
- wherein, the implant comprises a spherocylindrical configuration when in a non-compressed condition, and comprises a deformed spherocylindrical configuration comprising a substantially hemi-spherocylindrical configuration when in a compressed condition by being located in situ within a joint cavity defined by the articulating two-component hinge joint, and wherein the filler comprises a material with a coefficient of friction that allows opposite sides of the sac to move relative to one another when a force is applied to the joint, and an outer surface of the sac is arranged not to move relative to the naturally occurring joint component surface it is in contact with, during articulation, and wherein the amount of filler material is just sufficient to allow the relative movement within the sac.
