Claim:
1. A fastener apparatus for fusing a joint between a first bone portion and a second bone portion, the apparatus comprising: a distal segment, the distal segment having external threading configured to engage osseous tissue of the first bone portion; a proximal segment, the proximal segment having external threading configured to engage osseous tissue of the second bone portion; and an intermediate segment having an expandable member between the distal and proximal segments configured to be positioned in the joint between the first bone portion and the second bone portion, wherein the proximal segment, the distal segment and the intermediate segment each include a bore which together form a lumen of the fastener apparatus; an actuation component extending through the lumen, the actuation component including: wherein the expandable member is configured to expand by movement of the proximal segment and the distal segment-relatively toward each other using the actuation component; wherein movement of the proximal segment relatively toward the distal segment is configured to apply a compressive force to the first and second bone portions.
