Abstract
An external fixation system has a planar ring with an adjustable device having a body releasably mounted on the ring. The adjustable device includes a first member for movement in a direction generally perpendicular to the ring. A second member is mounted on the first member for movement in a direction parallel to a side wall of the planar ring. A method for treating a broken bone includes providing an external fixation system and inserting a first k-wire or half pin through a first piece of the bone and affixing the first k-wire or half pin to the ring, then inserting a second k-wire or half pin through a second piece of bone and affixing the second k-wire or half pin to the adjustable device. The pieces of bone are realigned, compressed, or distracted by adjusting at least one of the first and second adjustable members.
