Abstract: Disclosed herein are cable plugs for securing surgical cable to a bone plate. The cable plugs each have a cable retaining member and a fastening member. The cable retaining members each have a receiving portion adapted to receive a portion of the surgical cable therein. The cable retaining members are first coupled to the fastening members prior to securing the cable plug to the bone plate. The cable retaining member may rotate with respect to the fastening member about 270° along a longitudinal axis of the cable plug when the cable retaining member is coupled to the fastening member. When securing the surgical cable to the bone plate, the cable retaining member is rotated about the longitudinal axis of the cable plug until an axis of the receiving portion is parallel to an axis of the surgical cable. The surgical cable is then placed within the receiving portion, tightened, and crimped to secure the bone plate to the bone.

Abstract: A fixation clamp, more particularly for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements, has at least one clamping assembly having at least one reception to accommodate a fixation element along the longitudinal axis of the reception and at least one locking element extending through the clamping assemblies for blocking the position of the clamping assemblies in a defined angular position. Between said locking element and said at least one clamping assembly there is arranged a washer. The clamping assembly comprises a first contact surface which is spherical and convex and in that said washer comprises a second contact surface which is spherical and concave, wherein the first contact surface is in contact with the second contact surface.

Abstract: A medical system includes parts used in a method for detachably establishing a spatial orientation between a body implant and an aiming device. A positioning arm being connected to the aiming device and an adaptor device being connected to or integrally formed with a bone stabilizing plate are hooked into each other. This is accomplished by means of an engaging element of the positioning arm, which engaging element is designed such that it may be coupled with an attachment element of the adaptor device. Further, there is provided a snapping mechanism which is designed to automatically engage in an interlocking element of the adaptor device, when the positioning arm, when hooked into the adaptor device, is rotated relative to the adaptor device towards a final angular position.

Abstract: A tensioning device for surgical elements is described. The tensioning device comprises a fixation device, a clamping device, a spring device, and a force deflecting device that interacts with the clamping device. The force deflecting device is designed to convert the spring force exerted by the spring device on the clamping device into a clamping force exerted by the clamping device on the surgical element.

Abstract: A bone fastener for use in orthopedic surgery for fixing an implant to bone has a threaded or unthreaded shaft configured to engage bone and a head having a thread on an outer surface to engage the implant. The thread on the head of the fastener has a profile in cross section that includes peaks with a curved shape.

Abstract: A fixation clamp for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements has at least one clamping assembly having a pair of jaws with at least two different size grooves to accommodate a bone fixation element such as a pin or rod. An alternate clamping assembly has at least three grooves wherein at least two of the grooves have a different size adapted to accommodate a correspondingly sized bone fixation element such as a bone pin. The longitudinal axes of the grooves define a polygon. The jaw pairs can be rotated about a central longitudinal axis to present different size reception cavities towards the pins or rocks depending on their diameter.

Abstract: A tissue protection sleeve for use with a drill alignment assembly for a bone plate includes a tubular body having a first end and a second end. A hole extending from the first end to the second end is formed in the tubular body. The hole has a first center line. An expanded section is formed at the second end, the expanded section has a second center line. A first nose is formed at the first end, the first nose is adapted to fit in a screw hole in the bone plate such that the sleeve is rigidly fixed to the bone plate. The drill alignment assembly further includes an aiming arm adapted to mount to a bone plate and a drill guide insertable in the tissue protection sleeve.
