Devices for supporting bony structures

A device for supporting weak bony structures, comprising:

• a body having a first end and a second end for contacting a bony structure, said body having a wall extending therearound and a hollow chamber defined by an inner surface of said wall, said inner surface defining a perimeter therearound;
• and
• an end cap positionable in said hollow chamber adjacent one of said ends of said body, said end cap having a central ring and a plurality of curved arms extending radially from said ring, at least one of said plurality of arms contactable with said body to maintain said end cap in said hollow chamber.

A device for supporting weak bony structures, comprising:

• a body having a first end and a second end for contacting a bony structure, said body having a wall extending therearound and a hollow chamber defined by an inner surface of said wall;
• and
• an end cap for placement in said hollow chamber adjacent one of said ends of said body, said end cap having opposite upper and lower surfaces and at least one opening therebetween to permit bone growth therethrough, said upper and lower surfaces defining parallel planes and said end cap having a plurality of arms deformable generally within said planes from a pre-insertion configuration to a reduced size configuration for insertion of said end cap into said hollow chamber, said plurality of arms biased from said reduced size configuration to said pre-insertion configuration to contact said wall to maintain said end cap in said hollow chamber.

A device for supporting weak bony structures, comprising:

• a body having a first end and a second end for contacting a bony structure, said body having a wall extending therearound and a hollow chamber defined by an inner surface of said wall, said chamber adapted to receive bone growth material therein;
• and
• an end cap for placement in said hollow chamber adjacent one of said ends of said body, said end cap having opposite upper and lower surfaces, said upper and lower surfaces defining parallel planes and said end cap having a plurality of arms deformable generally within said planes from a pre-insertion configuration to a reduced size configuration for insertion of said end cap into said hollow chamber, said plurality of arms biased from said reduced size configuration to said pre-insertion configuration to contact said wall to maintain said end cap in said hollow chamber.
