Implant for engagement between vertebrae, and implant kit

A method for implanting an implant between vertebrae, wherein the implant has a central axis and comprises a monolithic body comprising:

• a first end and a second end opposite to the first end, wherein the central axis extends from the first end to the second end;
• an inner surface and an outer surface each extending axially from the first end to the second end;
• a plurality of teeth at the first end, wherein each of the teeth extends axially away from the second end to a free end;
• a first extension that extends radially inwardly from the inner surface and that forms a first abutment surface that faces away from the second end;
• and
• a second extension that extends radially inwardly from the inner surface and that forms a second abutment surface that faces away from the second end, wherein the first and second abutment surfaces are substantially similar to one another, and wherein an inner space defined by the inner surface and the first and second extensions is free from any axially extending portions of the implant, such that the first and second extensions are completely axially spaced apart from one another;
• the method comprising:
• adjusting an axial length of the implant, wherein the axial length of the implant is configured to be adjusted by cutting and removing a portion of the monolithic body at the first end from the rest of the implant to form a cut end, with one of the first or second abutment surfaces being selectively exposed at the cut end;
• and
• implanting the implant between vertebrae, wherein the one of the first or second abutment surfaces that is selectively exposed at the cut end is configured to engage one of the vertebrae.

An implant that is implantable between vertebrae, wherein the implant has a central axis and comprises:

• a monolithic first body having a first end and a second end opposite to the first end, wherein the central axis extends from the first end to the second end, and wherein the monolithic first body comprises an inner surface and an outer surface each extending axially from the first end to the second end, a first extension that extends radially inwardly from the inner surface and that forms a first abutment surface that faces away from the second end for engaging a vertebra when the implant is implanted, and a second extension that extends radially inwardly from the inner surface and that forms a second abutment surface that faces away from the second end, wherein an inner space defined by the inner surface and the first and second extensions is free from any axially extending portions of the monolithic first body, such that the first and second extensions are completely axially spaced apart from one another;
• and
• a second body connected to and that is movable axially relative to the monolithic first body for adjusting a length of the implant measured in a direction of the central axis;
• wherein the monolithic first body is configured to be cut to length between the first and second ends, such that when a portion of the monolithic first body comprising the first abutment surface is cut and removed from the rest of the implant, a cut end that is devoid of the first abutment surface and where the second abutment surface is exposed is formed on the monolithic first body that remains configured to engage the vertebra when the implant is implanted, with the engagement of the vertebra by the cut end being substantially similar to engagement of the vertebra by the first end.
