Polymeric joint complex and methods of use

Abstract

The invention describes a variety of implantable artificial joint complexes adapted for implantation within a target joint space within a human body. The joint complexes comprise: an expandable joint segment adapted to fit within the target joint space; and at least one of a first cannulated anchor adapted to engage the expandable joint segment and adapted to engage a bony structure adjacent the target joint space; and a second anchor adapted to engage the expandable joint segment and adapted to engage a bony structure adjacent a target joint space. The invention also discloses methods of implanting a patient specific artificial joint complex. The methods include the steps of: accessing a target joint space by creating an access hole through an adjacent bony structure; inserting a joint complex device having a cannulated anchor and an expandable joint segment through the access hole with the expendable joint segment being positioned between the surfaces forming the joint; injecting material into the expandable joint segment; and sealing access to the target joint space.
