Abstract
The present invention relates to skeletal reconstruction cages and a method of providing variable fit for a skeletal reconstruction cage. The 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.
Claims33
A skeletal reconstruction cage comprising:
- a central body having first and second ends;
- a first end cap;
- and
- a second end cap,
- wherein the first end cap is coupled to one end of the central body and the second end cap is coupled to the other end of the central body.
A method of providing variable fit for a skeletal reconstruction cage, the method comprising:
- providing a first set of central bodies, each central body having a different maximum height from one another;
- providing a second set of top end caps of variable sizes, each top end cap having a different maximum height from one another;
- providing a third set of bottom end caps of variable sizes, each bottom end cap having a different maximum height from one another;
- selecting the central body, top end cap, and bottom end cap that provide preferred skeletal reconstruction cage height when coupled together;
- coupling the first and second end caps to the central body to form a first skeletal reconstruction cage, with the end caps disposed on opposing ends of the central body.
A skeletal reconstruction cage comprising:
- a central body having first and second free ends, each end comprising a receiving region;
- a first end cap coupled to one free end of the central body and comprising a first protruding region;
- and
- a second end cap coupled to the other free end of the central body and comprising a second protruding region,
- wherein the first protruding region and the second protruding region are configured and dimensioned to be received in the receiving regions, and wherein each of the regions is symmetrical about at least one central plane extending generally perpendicular to the first and second free ends.
An end cap for use with a skeletal reconstruction cage, comprising a cap body having a top face disposed in a first cap plane and a bottom face disposed in a second cap plane transverse to the first cap plane, wherein the first and second cap planes are disposed at a cap angle with respect to each other.
