The present embodiments relate to a joint treatment device for improved
treatment of a diseased joint. The joint treatment device comprises first
and second components, which are coupled to first and second bone
portions, respectively, at the joint. The first component and the second
component are configured to be coupled together in a first configuration
to promote fusion of the joint, and further are configured to be coupled
together in a second configuration to promote arthroplasty of the joint.
Additionally, a screwdriver is disclosed that may advance the first and
second component simultaneously or independently. Further, a joint
distraction device is disclosed, which may be used to vary spacing
between the first bone portion and the second bone portion at the joint.
