Abstract
Skeletal reconstruction cages include a central body having first and second ends, a first end cap coupled to one end of the central body, and a second end cap coupled to the other end of the central body. At least two of the central body, first end cap, and second end cap are formed from bone. Each of the central body, first end cap, and second end cap may be provided in different sizes so that cages with varying overall heights, and related angulations, may be created.
Claims45
A skeletal reconstruction cage comprising:
- a central body having first and second flat end faces;
- a first end cap having a first base portion, and a ridge portion defining a first ridge face;
- and
- a second end cap having a second base portion, and a ridge portion defining a second ridge face,
- wherein the first end cap is coupled to one end of the central body with the first ridge face abutting an end face of the central body, the second end cap is coupled to the other end of the central body with the second ridge face abutting an end face of the central body, and at least one of the central body, first end cap, and second end cap is formed of bone.
A skeletal reconstruction cage comprising:
- a central body comprising a first end, a second end, and a substantially continuous outer wall extending therebetween;
- a first end cap;
- and
- a second end cap,
- wherein the first end cap is coupled to one end of the central body, the second end cap is coupled to the other end of the central body, and at least one of the end caps is formed of bone.
A skeletal reconstruction cage comprising:
- a central body having first and second free ends, each end comprising a receiving region defining a recessed shoulder extending toward a central axis of the central body;
- a first end cap coupled to one free end of the central body and comprising a first central protruding region;
- and
- a second end cap coupled to the other free end of the central body and comprising a second central protruding region,
- wherein the first central protruding region and the second central protruding region are each configured and dimensioned to be received in the receiving regions so that torsional rotation of the protruding regions is resisted therein, each of the regions is symmetrical about at least one central plane extending generally perpendicular to the first and second free ends, and at least one of the first end cap and second end cap is formed of bone.
