ABSTRACT:
A barrier is placed across a portion of or across the totality of a spinal implant. The barrier can serve a variety of purposes, including, for example: (1) to keep tissue away from the implant and minimize or eliminate the likelihood of tissue adhesion with the spine or implant; (2) to decrease or eliminate the likelihood of tissue growth, migration, invasion and/or interaction with the implant; (3) to decrease or eliminate the likelihood of the dissemination of implant wear debris and particles away from the implant and into body cavities; and (4) to decrease or eliminate the likelihood of calcification, ossification, and/or bone formation adjacent to the implant.
