Abstract
A bone displacement system includes a removable guide and frame. The removable guide includes a proximal anchoring portion and a distal anchoring portion. The proximal anchoring portion has a proximal anchoring aperture for receiving a first wire to connect the guide to a proximal bone. The distal anchoring portion has a distal anchoring aperture for receiving a second wire to connect the guide to a distal bone. The guide includes a slot configured to receive a tool. The frame includes a compression-distraction mechanism and a rotation mechanism. The compression-distraction mechanism is connected to the rotation mechanism and engageable with the proximal bone. The rotation mechanism includes a distal aperture for receiving the second wire to connect the rotation mechanism to the distal bone, and the compression-distraction mechanism is configured to move the rotation mechanism and the distal bone relative to the proximal bone. Further disclosed is a bone displacement method.
