Modular bone graft cage

A graft cage system, comprising:

• a first graft cage including:
• a plurality of first graft cage cross-sectional portions, each of the first graft cage cross-sectional portions including (a) a plurality of base transverse members forming a base of the first graft cage, (b) a first arm including a plurality of first arm transverse members, (c) a second arm including a plurality of second arm transverse members, (d) a plurality of base connecting struts, each of the base connecting struts extending between a first one of the base transverse members and a second one of the base transverse members, (e) a plurality of first arm connecting struts, each of the first arm connecting struts extending between a first one of the first arm transverse members and a second one of the first arm transverse members, and (f) a plurality of second arm connecting struts, each of the second arm connecting struts extending between a first one of the second arm transverse members and a second one of the second arm transverse members;
• and
• a plurality of longitudinal members connecting the first graft cage cross-sectional portions to one another, intersections of the first graft cage cross-sectional portions with the longitudinal members forming first pores in the first and second arms;
• a second graft cage including:
• a plurality of second graft cage cross-sectional portions, each of the second graft cage cross-sectional portions including (a) a plurality of base transverse members forming a base of the second graft cage, (b) a first arm including a plurality of first arm transverse members, (c) a second arm including a plurality of second arm transverse members, (d) a plurality of base connecting struts, each of the base connecting struts extending between a first one of the base transverse members and a second one of the base transverse members, (e) a plurality of first arm connecting struts, each of the first arm connecting struts extending between a first one of the first arm transverse members and a second one of the first arm transverse members, and (f) a plurality of second arm connecting struts, each of the second arm connecting struts extending between a first one of the second arm transverse members and a second one of the second arm transverse members:
• and
• a plurality of longitudinal members connecting the second graft cage cross-sectional portions to one another, intersections of the second graft cage cross-sectional portions with the longitudinal members forming second pores in the first and second arms;
• and
• a third graft cage comprising:
• a plurality of third graft cage cross-sectional portions, each of the third graft cage cross-sectional portions including (a) a plurality of base transverse members forming a base of the third graft cage, (b) a first arm including a plurality of first arm transverse members, (c) a second arm including a plurality of second arm transverse members, (d) a plurality of base connecting struts, each of the base connecting struts extending between a first one of the base transverse members and a second one of the base transverse members, (e) a plurality of first arm connecting struts, each of the first arm connecting struts extending between a first one of the first arm transverse members and a second one of the first arm transverse members, and (f) a plurality of second arm connecting struts, each of the second arm connecting struts extending between a first one of the second arm transverse members and a second one of the second arm transverse members;
• and
• a plurality of longitudinal members connecting the third graft cage cross-sectional portions to one another, intersections of the third graft cage cross-sectional portions with the longitudinal members forming third pores in the first and second arms, wherein the first, second, and third graft cages are sized, shaped and configured so that a free end of the first arm of the first graft cage may be interlocked with a free end of the second arm of the second graft cage while a the free end of the first arm of the second graft cage is interlocked with a free end of the second arm of the third graft cage and a free end of the first arm of the third graft cage is interlocked with a free end of the second arm of the first graft cage, the first pores being sized and shaped and configured to receive the free end of the second arm of the second graft cage on the first arm of the first graft cage and to receive the free end of the first arm of the third graft cage on the second arm of the first graft cage therein to interlock the first graft cage with the second and third graft cages.
