Abstract
This invention provides, inter alia, a device having a cage having an opening or window in at least one of its walls that allows for the insertion of bone growth promoting materials therethrough, comprising one or more openings in one or more of the walls of the cage, designed to receive bone growth promoting materials, including coral-based materials, which facilitate in the fusion with the treated bone, and which optionally serves to reinforce the stability of the implanted structure. Methods of stabilizing two skeletal structures relative to one another, joining two skeletal structures which are discontinuous and repairing a ligament tear or replacing a ligament making use of a bone fusion device of the invention are described.
Claims32
A bone fusion device forming a rigid structure between adjoining regions in one or more bones comprising a cage frame defined by a top cage frame element, a bottom cage frame element and lateral cage frame elements, said top cage frame element and said bottom cage frame element designed to be positionable between and be at least partially load bearing for a surface of an adjacent bone, and wherein at least one of said top and bottom cage frame element include an opening to receive a bone growth promoting material, which facilitates the fusion of said one or more bones, and which optionally serves to reinforce the stability of the implanted fusion device between said adjoining regions in said one or more bones, wherein said bone growth promoting material is comprised of a solid block which block is machined or structurally modified to include a modified surface of said bone growth promoting material into which at least a portion of at least one cage frame element inserts seamlessly therein so that an outer face of said bone growth promoting material is neither protruding nor recessed with respect to said at least one cage frame element.
