Systems and methods for the fixation or fusion of bone
First Claim
1. A method comprisingproviding a bone fixation/fusion device comprising a rectangular body and first and second fixation ridges on the body, the first and second fixation ridges being separated by a ridge separation distance,selecting a bone site comprising a first bone segment, a second bone segment, and a non-bony region comprising an interruption between the first and second bone segments,forming a first bone cavity in the first bone segment including forming a first slot sized and configured to receive the first fixation ridge,forming a second bone cavity in the second bone segments across the interruption from the first bone cavity including forming a second slot sized and configured to receive the second fixation ridge, the first and second slots being separated by a slot separation distance that is greater than the ridge separation distance, andinserting the body in the first bone cavity, the second bone cavity, and the interruption with the first and second fixation ridges nesting within the first and second slots, respectively, to apply compression between the first and second bone segments.

2. A method comprising
identifying a bone site comprising a first bone segment, a second bone segment, and a joint between the first and second bone segments, providing a first elongated bone fusion device including an exterior surface treated to provide bony in-growth, providing a second elongated bone fusion device including an exterior surface treated to provide bony in-growth, and fusing the joint by passing the first elongated bone fusion device in a first path through the first bone segment, across the joint, and into second bone segment, passing the second elongated bone fusion device in a second path through the first bone segment, across the joint, and into second bone segment, the first and second paths crisscrossing within the bone segments, the exterior surfaces of the first and second elongated bone fusion device providing bony in-growth within the crisscrossing first and second paths.
