Abstract
A bone fusion implant includes a rigid body having a distal end, a proximal end and a longitudinal axis extending between the distal and proximal ends and a concave channel formed in the body between the distal and proximal ends, the concave channel being formed about an axis extending in a direction substantially perpendicular to the longitudinal axis of the body. The body has a first rigid cylindrical outer wall extending between the distal end of the body and the concave channel and a second rigid cylindrical outer wall extending between the proximal end of the body and the concave channel. The body also has a first opening at the distal end, a second opening at the proximal end and a hollow, internal chamber extending between the first and second openings.

A bone fusion implant comprising:
- a rigid body having a distal end, a proximal end and a longitudinal axis extending between said distal and proximal ends;
- a concave channel formed in said body between said distal and proximal ends, said concave channel being formed about an axis extending in a direction substantially perpendicular to said longitudinal axis of said body;
- said body having a first rigid cylindrical outer wall extending between said distal end of said body and said concave channel;
- and
- said body having a second rigid cylindrical outer wall extending between said proximal end of said body and said concave channel, wherein said body has a first opening at said distal end, a second opening at said proximal end and a hollow, internal chamber extending between said first and second openings.
A bone fusion implant comprising:
- a rigid body made of metal having a distal end, a proximal end and a longitudinal axis extending between said distal and proximal ends;
