Patent ID: 7938834

Claim:
Apparatus suitable for treating a medical condition, the apparatus comprising: a first component having proximal and distal ends and a generally cylindrical solid body that is adapted to be engaged with a first bone portion at a joint; and a second component having proximal and distal ends, the second component comprising a generally cylindrical body having a hollow interior region, wherein the generally cylindrical solid body of the first component is adapted to be selectively placed within the hollow interior region of the second component, and the second component is adapted to be engaged with a second bone portion at the joint, wherein the first component and the second component are configured to be coupled together in a first configuration to promote fusion of the joint, and the first component and the second component are further configured to be coupled together in a second configuration allowing for rotation relative to each other to promote arthroplasty of the joint, wherein the proximal end of the first component and the proximal end of the second component each comprise at least one recess adapted to engage a portion of a tool to enable manipulation of the first and second components; and a fusion component having a first portion comprising a substantially cylindrical body having external threading configured to mate with internal threading of the second component, and further comprising a second portion comprising external threading configured to mate with internal threading of an additional recess of the first component to promote fusion of the joint.
