Abstract
Abstract A device for supporting weak bony structures includes a body having first and second ends configured for contacting adjacent bony structures. The body has a wall that with a number of opening, and the wall defines a hollow chamber for receiving bone growth inducing material. The device includes an end cap for placement in the hollow chamber adjacent one of the ends of the body. The end cap has opposite upper and lower surfaces, and includes a plurality of arms extending from a central ring. Each of the arms having a first end connected with the ring and an opposite second end including an outer surface. Each of the outer surfaces are positionable adjacent the inner surface of the wall of the body when the end cap is inserted into the hollow chamber. Each arm can also include a projection that extends at least partially into a wall opening.
