Method for using a guard for creating a socket posteriorly in the lumbar spine
First Claim
1. A method for inserting a bone implant into a posterior aspect of the human spine, comprising:
- placing a guard against the posterior aspect of the spine, the guard having a passage therethrough;
inserting a bone removal device into the passage of the guard, the bone removal device having a cutting portion;
drilling a portion of a facet joint with the bone removal device to create a socket having a maximum height; and
inserting a bone implant into the socket created by the bone removal device, the bone implant having a leading end, a trailing end, a mid-longitudinal axis through the ends, and a height transverse to the mid-longitudinal axis, the height of the bone implant being greater than the maximum height of the socket.

Abstract
A method for guiding a bone removal device to form a socket in the human spine and for inserting a cortical bone implant into the socket. The method includes placing a guard against the posterior aspect of the spine, the guard having a passage therethrough, inserting the bone removal device into the passage, removing a portion of a facet joint with the bone removal device to create the socket having a maximum height, and inserting the cortical bone implant into the socket. The cortical bone implant has a leading end, a trailing end, a mid-longitudinal axis through the ends, and a height transverse to the mid-longitudinal axis, the height of the cortical bone implant being greater than the maximum height of the socket.

11. A method for inserting a bone implant into a posterior aspect of the human spine, comprising:
-
placing a guard against the posterior aspect of the spine, the guard having a passage therethrough; forming a socket through a portion of a facet joint using a bone removal device inserted through the passage of the guard, wherein forming the socket includes compacting portions of bone forming the socket to increase the density of the bone forming the socket, the socket having a maximum height; and inserting a bone implant having a circular cross section into the socket, the bone implant having a leading end, a trailing end, a mid-longitudinal axis through the ends, and a height transverse to the mid-longitudinal axis, the height of the bone implant being greater than the maximum height of the socket. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
