Abstract

A facet joint replacement system includes a facet joint replacement device including an enclosing body and an articulating body. The enclosing body includes an interior surface defining an inner cavity of the enclosing body. The interior surface includes a first articulating surface and a projection extending inwardly relative to a surrounding area of the interior surface. The articulating body is positioned within the inner cavity of the enclosing body and is configured to move within the enclosing body. The articulating body includes a second articulating surface and a recess extending inwardly relative to a surrounding area of the articulating body and aligned with the projection of the interior surface of the enclosing body so as to allow movement of the projection along the recess of the enclosing body while constraining rotational motion of the articulating body within the enclosing body.

Dependent claims

A facet joint replacement system, comprising:

a facet joint replacement device, the facet joint replacement device comprising:
an enclosing body comprising an inner cavity and a channel;
and
an articulating body positioned within the inner cavity of the enclosing body;
a device holder configured to couple with the facet joint replacement device, the device holder comprising:
a shaft;
a handle coupled to the shaft and configured to be grasped by a user;
and
a fastening head coupled to the shaft, the fastening head configured to couple with the facet joint replacement device to constrain movement of the articulating body within the enclosing body during implantation of the facet joint replacement device, wherein the fastening head is configured to disengage from the facet joint replacement device after implantation of the facet joint replacement device, wherein the channel of the enclosing body is configured to removably receive the fastening head of the device holder;
and
a plug, wherein the channel of the enclosing body is configured to receive the plug after removal of the fastening head from the channel.
