    摘要: The invention relates to an osteosynthesis implant (1) that preferably consists of a bioresorbable plastic material. The inventive implant receives the longitudinal fixation elements (10) to be anchored in the bone, especially in the form of wires, nails, pins or screws. The openings destined to receive the fixation elements (10) do not completely extend through the implant (1) like in conventional bone plates or intramedullary nails but are degenerated to indents (2) in the surface of the implant (1) so that they may serve as a guide for the fixation elements (10) to be guided through the implant (1). The inventive implant (1) allows insertion of the fixation elements (10) in the bone diverging angles and crossing one another, so that the fixation elements (10) extending intramedullarly or in the spongiosa are primarily prevented from migrating in a proximal or distal direction.

    摘要: The invention is related to an intramedullary nail for fixation of a fractured bone having a medullary canal. The intramedullary nail may comprise a first radially expandable section provided in a proximal section adjacent to the head of the intramedullary nail, a second radially expandable section provided in the distal section adjacent to the tip of the intramedullary nail, and a non-expandable middle section provided between said two radially expandable sections of the intramedullary nail. The head may provide a distraction mechanism, by means of which said two radially expandable sections are distractible transverse to said longitudinal axis.

    摘要: A device to be used in combination with a surgical navigation system for defining the position of a straight line determined by an operating surgeon within a three-dimensional coordinate system in an operating theater. The devices includes a body (1) with a surface (2) and at least three markers (3) which emit waves (19) and the position of which can be determined within a three-dimensional coordinate system by a position detector belonging to the surgical navigation system. A laser (4) mounted on the body (1) emits a laser beam (5), directed away from the body (1), which has a geometrical central beam (6) and a wavelength in the visible range. The laser beam (5) is emitted in a geometrically defined position relative to the markers (3) so that the position of the central beam (6) relative to the three-dimensional coordinate system can be calculated from the previously measured positions of the markers (3) by a computer, which is also part of the surgical navigation system.

    摘要: The invention is related to a method for the determination of reduction parameters for the subsequent adjustment of a reduction device to reduce the fragments of a fractured bonee. The method comprises: measuring points on the surfaces of the corresponding bones of interest at the patient's left and right side of the body; establishing a plane of symmetry containing an anterior-posterior axis and a proximal-distal axis; generating a mirror image of the patient's non-fractured bone symmetrically to the plane of symmetry; and determining the reduction parameters by comparison of the coordinates of the points at the fractured bone with the coordinates of the points within the mirror image. The device according to the invention comprises: a cylindric or prismatic reference bar; clamps displaceable on and fastenable to the reference bar; screws or pins screwable into the bone transversely to the reference bar within the clamps; and an adjustable clamp to fasten a pin capable of being set with its tip to desired points on the surface of the bone.

    摘要: A bone tissue removal and harvesting device is disclosed and includes a cutting tool with a cutting head, a longitudinal shaft attached to the cutting head and a drive element. A container is located on the end opposite the cutting head for collection of the removed bone. The shaft can be made flexible to permit torsion and/or bending around the longitudinal axis without damage to the bone. During the cutting operation, the bone tissue is simultaneously removed and suctioned through an opening of the cutting head and conveyed through an axial shaft bore for collection in the container. The container is detachably mounted to the drive element and connected to the shaft so as to avoid substantial pressure drops from the cutting head to the container.

    摘要: A bone augmentation device for attachment of soft tissue to bone by sutures includes a bone plate having top and bottom surfaces spaced equidistant from a central plane. At least one hole extends between the top and bottom surfaces and the holes preferably have rounded edges to minimize the potential to damage the suture. The central plane includes a longitudinal and a horizontal axis and the plate is curved along the longitudinal and horizontal axes to provide for a secure fit against the bone. The plate is made of a non-resorbable material.

    摘要: A bone plating system for the internal stabilization of a fractured bone is disclosed. The system includes a bone plate having a plurality of conical plate holes tapering toward a bone contact surface and at least two bone screws for anchoring the bone plate to a bone. The screws have a conical head with a textured or structured lateral outside surface which is greater in hardness than the portion of the bone plate which is proximal to the plate holes. The present system provides positive locking between the screw heads and the plate holes.
