Abstract
A device to establish a connection of portions of a broken bone includes a base body adapted to receive a bone nail. A clamping holder has a receptacle to receive a fixation rod. A bearing element mounts the clamping holder on the base body for spherically displacement. A tensioning rod connection has a tensioning rod on which the base body, the clamping holder and the bearing element are arrangeable in a row for tensioning relative to each other. In a first connection state the tensioning rod connection is released so that the fixation rod and base body are adjustable relative to each other. In a second connection state there is sufficient closing tension in the tensioning rod connection to form a stable non-positive locking connection between the fixation rod and the base body. The clamping holder and the bearing element are in positive engagement in the first connection state with the tensioning rod passing through a through-opening of the clamping holder with sufficient play for spatial guiding in all directions.
