Abstract

A faceplate for at least partially covering a plurality of anchor member apertures in an implantable member includes a main body sized to at least partially overlap the plurality of anchor member apertures of the implantable member and configured to inhibit anchor member back-out from the plurality of anchor member apertures. A locking tab may be associated with the main body, the locking tab being formed to at least partially elastically deform to engage the implantable member and secure the main body in place.

Description

technical field [0001] The present invention relates generally to the field of replacing parts of human anatomy with medical grafts. Background technique [0002] Spinal discs between the endplates of adjacent vertebrae (vertebrae) in the human spine provide critical support. However, due to injury, degeneration, disease, or the like, these discs can rupture, degenerate and / or protrude to such an extent that the intervertebral space between adjacent vertebrae collapses due to the loss of the disc at least Some support functions. This can cause nerve root shock and neuralgia. In some cases, surgical correction may be required. [0003] Some surgical corrections involve the removal of a natural spinal disc from between adjacent vertebrae. To preserve disc space for normal spinal function, graft elements may be inserted between adjacent vertebrae. [0004] Certain graft elements employ anchor elements that hold the graft element in place between adjacent vertebrae. Over t...
