  • Patent number: 8486071
    Abstract: A short nail for treatment of an epiphyseal fracture close to a joint in a long bone includes a two part nail supporting body comprising a main body having a transverse through-bore and releasably attached to a stub body. The stub body has an end that has a diaphyseal slant. The stub body and the lateral slant form part of a diaphyseal anchor which is attachable to the main body via the stub body and which has a flat connecting web that has an oblique orientation and ending laterally in a plane with the diaphyseal slant. A connecting device rigidly and releasably connects the main body and the stub body together. An anchoring device fixes the flat web in flat abutment against the diaphysis. A fixation pin is insertable into the transverse through-bore in a crossed arrangement with, and at a fixed angle to, the supporting body in the state of treatment of the fracture. The fixation pin includes a mechanism to protect against axial movement of the pin.

  • Patent number: 8147490
    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.

  • Publication number: 20090299368
    Abstract: The invention relates to a fixation device for stably interlinking at least two bone fragments of a broken bone. Said fixation device comprises at least one base for receiving at least one fracture pin and at least one fixation rod. The base and the fixation rod, in a first interlinked state, are released to adjust their relative position, and in a second interlinked state, are figidly interlinked to fixate the adjusted position. A clamping holder received by the base by means of bearings in such a manner that its angle can be adjusted receives a fixation rod. The base, the clamping holder and the bearing are arranged in series in a prestressing bar connection. The clamping holder is configured by a holder which, in an area for adjusting and maintaining the adjusted position, is guided on the base in all directions in space. The clamping holder and at least one bearing element of the bearing through which a prestressing bar extends are positively locked, thereby providing spatial guidance.
