  • Patent number: 8533968
    Abstract: A method and a device are for determining the compatibility between an adapter, which is to be inserted into a third-party joint ball type to be replaced, and an outer cone of a prosthesis shaft of a modular joint prosthesis, which is inserted in the femur during revision surgery. A test body of a set of test bodies having various inner cones, comprising a marker and a length measuring scale, is fitted onto the outer cone of the shaft of the joint prosthesis and, subsequently, the adapter fitting on the outer cone of the joint prosthesis is determined by successively testing the inner cones for compliance with an admissible minimum distance between the front faces of the outer cone of the shaft of the joint prosthesis and the inner cone and for compliance with an admissible predefined insertion depth of the outer cone of the shaft of the joint prosthesis in the inner cone of the test body.

  • Patent number: 8518122
    Abstract: The invention relates to modular joint prostheses, comprising a curved head part to the conical pins of which a slip-on joint ball is attached, and comprising a nail which can be inserted into the bone marrow canal of the long bone and has a nail neck, wherein a connecting means is provided between the head part and the nail neck which holds the head part in a non-rotatable manner. The connecting means comprises at least one collar-like module which is located in the axial direction of the nail and has at least two semi-shells, which are divided in the axial direction of the module, are detachably connected to each other, form an axially extending passage for inserting the nail head into the passage and have recesses for receiving a tensioning means, which in the tensioned state fixes the nail head in the passage exclusively by way of factional engagement.

  • Patent number: 8496711
    Abstract: A knee arthrodesis implant has a femur nail inserted in the bone marrow canal of the femur, and a tibia nail inserted in the bone marrow canal of the tibia, the nails being rigidly connected to each other by a connecting means. The problem of providing a knee arthrodesis implant having increased modularity as the result of increased length variability, having a reduced number of parts, and allowing simplified modification is addressed.

  • Publication number: 20130165981
    Abstract: A bone plate system for osteosynthesis comprises a bone plate, a swivel screw, a clamping screw, a swivel hole formed in the bone plate as a through hole for receiving the swivel screw polyaxially, and a clamping hole, which is associated with the swivel hole and is formed in the bone plate as a further through hole for receiving the clamping screw. When the swivel screw and the clamping screw are screwed in, they are fixed with angular stability in multiple dimensions, as the screw heads of the swivel screw and of the clamping screw are secured by one another and by the bone plate against relative movement. The swivel screw and the clamping screw are each designed as a bone screw.

  • Publication number: 20120265320
    Abstract: A joint prosthesis system has a metal shaft, which is implanted in the femur, a throat having an outer cone, a joint ball made of ceramic and an accommodation for the throat. The accommodation has an inner cone, and a sheath-shaped adapter, which is arranged between the shaft and the joint ball in a clamping manner. Due to an exceptional elasticity and a special shaping of an inner and outer wall section of the adapter, the application of force to a narrow surface region on the metal outer cone and the application of the force into the ceramic inner cone is extensively concentrated on a load-bearing region (B) opposite the narrow surface region within the largest mass expansion of the ceramic joint ball.

  • Patent number: 8177820
    Abstract: Disclosed is a bone plate comprising at least one screw that is to be fixed at a stable angle to at least one through-hole and at least one bone screw which is provided with an external thread in the top region. Said external thread tapers more in the screwing direction than a mating thread of the through-hole embodied as an internal thread such that the top of the bone screw is clamped in a stable direction in a torsion-proof manner when the bone screw is screwed in. The bone plate is configured elastically in at least one area adjoining the through-hole such that the material of the bone plate is not deformed in the ductile area because of the expansion resulting from the head of the bone screw being screwed in.

  • Publication number: 20110196503
    Abstract: The invention relates to modular joint prostheses, comprising a curved head part and/or a shaft-like shaped shaft part, to the conical pins of which a slip-on joint ball is attached, and comprising a nail which can be inserted into the bone marrow canal of the long bone and has a nail neck, wherein a connecting means is provided between the head part and the nail neck which holds the head part in a non-rotatable manner. The invention is based on the problem of providing a modular joint prosthesis which increases the modularity of the prosthesis by increased longitudinal variability, enables improved adjustability of the angular position while reducing the number of parts at the same time, and simplifies revision surgeries.
