Claims85
A method for inserting an implant across the disc space and into two adjacent vertebrae through a tubular member comprising the steps of:
- inserting a tubular member having means to engage said two adjacent vertebrae;
- placing through said tubular member a drill having a diameter greater than said disc space;
- drilling an opening across the disc space and into a portion of each of the two adjacent vertebrae through said tubular member;
- removing said drill;
- inserting an implant in the opening through the tubular member;
- and then removing said tubular member.
A method for removing the disc between two adjacent vertebrae comprising inserting a tubular member having means to engage two vertebrae into the vertebrae, said tubular member having a inner removable sleeve;
- drilling the disc and a portion of the two adjacent vertebrae through said tubular member;
- tapping the opening formed by the drill in the disc to create a thread in the vertebrae;
- inserting a cylindrical implant having corresponding threads to those formed by the tap in the vertebrae through the tubular member;
- and then removing said tubular member.
A method for removing the disc between two adjacent vertebrae comprising inserting a tubular member having means to engage two vertebrae into the vertebrae, said tubular member is installed in said vertebrae by placing a driver within said tubular member and hitting the driver with a hammer;
- drilling the disc and a portion of the two adjacent vertebrae through said tubular member;
- tapping the opening formed by the drill in the disc to create a thread in the vertebrae;
- inserting a cylindrical implant having corresponding threads to those formed by the tap in the vertebrae through the tubular member;
- and then removing said tubular member.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive at least one implant, the method comprising the steps of:
- positioning one end of a tubular member in contact with the adjacent vertebrae;
- forming, through said tubular member, an opening across the disc space and into a portion of each of the two adjacent vertebrae;
- and
- inserting said implant through said tubular member and into the opening.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive at least one implant, the method comprising the steps of:
- positioning one end of a substantially tubular member in contact with the adjacent vertebrae, said tubular member having at least a portion thereof extending into the disc space;
- forming, through said tubular member, an opening across the disc space and into a portion of each of the two adjacent vertebrae;
- and
- inserting said implant through said tubular member and into the opening.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive an implant, the method comprising the steps of:
- abutting one end of a tubular member against the adjacent vertebrae, said tubular member having at least a portion thereof extending into the spine;
- forming, through said tubular member, an opening across the disc space and into a portion of each of the two adjacent vertebrae;
- and
- inserting said implant through said tubular member and into the opening.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive an implant, the method comprising the steps of:
- contacting the adjacent vertebrae with one end of a tubular member;
- forming, through said tubular member, an opening across the disc space and into a portion of each of the two adjacent vertebrae;
- and
- inserting said implant through said tubular member and into the opening.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive an implant, the method comprising the steps of:
- burying into the disk space one end of a tubular member;
- forming, through said tubular member, an opening across the disc space and into a portion of each of the two adjacent vertebrae;
- and
- inserting said implant through said tubular member and into the opening.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive an implant, the method comprising the steps of:
- anchoring one end of a substantially tubular member against the two adjacent vertebrae so that at least a portion of said one end of said tubular member extends at least in part between the adjacent vertebrae and into the disc space;
- forming, through said tubular member, an opening across the disc space and into a portion of each of the two adjacent vertebrae;
- and
- inserting said implant through said tubular member and into the opening.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive an implant, the method comprising the steps of:
- non-distractively engaging the two adjacent vertebrae with one end of a tubular member;
- forming, through said tubular member, an opening across the disc space and into a portion of each of the adjacent vertebrae;
- and
- inserting said implant through said tubular member and into the opening.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive an implant, the method comprising the steps of:
- driving one end of a tubular member against the two adjacent vertebrae;
- forming, through said tubular member, an opening across the disc space and into a portion of each of the adjacent vertebrae;
- and
- inserting, through said tubular member, said implant into the opening.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive at least one implant, the method comprising the steps of:
- positioning one end of a hollow guard in contact with the adjacent vertebrae;
- a forming, through said hollow guard, an opening across the disc space and into a portion of each of the two adjacent vertebrae;
- and
- inserting said implant through said hollow guard and into the opening.
A method for preparing two adjacent vertebrae and a disc space therebetween to receive an implant, the method comprising the steps of:
- anchoring one end of a hollow guard against the two adjacent vertebrae so that at least a portion of said one end of said hollow guard extends at least in part between the adjacent vertebrae and into the disc space;
- forming, through said hollow guard, an opening across the disc space and into a portion of each of the two adjacent vertebrae;
- and
- inserting said implant through said hollow guard and into the opening.
