Abstract: An aiming jig for a tibia plate, including: a head the interfaces with a head of the tibia plate comprising: screw guide holes corresponding to screw holes in the head of the tibia plate; a fixation protrusion that engages a fixation opening in the head of the tibia plate, wherein an engagement of the fixation protrusion with the fixation opening aligns the head with the head of the tibia plate; and an arm extending from the head including a guide wherein the guide is configured to extend along an anterior portion of a tibia when the aiming jig is fixed to the tibia plate, and the guide includes a support screw guide hole that guides a placement of a support screw into the tibia in a generally anterior to posterior direction so that the support screw avoids interfering with plate screws placed in the head of the tibia plate.

Abstract: A method for treating an articular fracture of a tibia using a tibia plate with an extension arm, including: making an incision to expose the tibia; reducing the articular fracture of the tibia; contouring the tibia plate to fit the tibia; preliminarily fixing the tibia plate to the tibia; placing a screw partially into the tibia through a lateral elongated hole in the tibia plate; applying compression between a plate screw hole in the extension arm and an anterior surface of the tibia; and placing additional plate screws in the tibia through additional screw holes in the tibia plate.

Abstract: A method and a device for monitoring a power supply apparatus of a traffic system. A computer-based model of the power supply apparatus is created inter alia with the aid of predetermined parameters which are relevant for the power supply apparatus. The invention aims to meet changed requirements of modern power supply devices. Current characteristic quantities are determined during the operation of the traffic system and the operation of the power supply device is simulated at least with the aid of the model and the characteristic quantities.

Abstract: Various embodiments relate to a mini cable tensioner for introducing tension on a cable, the mini cable tensioner including a tensioning tube, a tensioning grip, including a collet opener as an internal structure of the tensioning grip, a tensioning unit, including a collet axially positioned in a cone sheath, a tensioning rod having a proximal end connected to an end stop nut and a distal end connected to the cone sheath, a tensioning nut rotatable on the tensioning rod, an inner spring configured to actuate the collet in a first direction, and an outer spring configured to actuate the tensioning rod in a second direction, the second direction being opposite to the first direction.

Abstract: A sacral fixation implant can include at least one implant segment, a guide wire, and at least one locking member that is configured to fix the implant segment to the guide wire. The implant segment can be configured to be secured to an ilium bone, and the guide wire can be configured to be secured to the sacrum. The implant can include first and second implant segments that are configured to be secured to opposed ilium bones, such that a first locking member is configured to fix the first implant segment to the guide wire, and a second locking member is configured to fix the second implant segment to the guide wire.

Abstract: Sacral fixation implants can include first and second implant segments. One of the first and second implant segments is received in the other of the first and second implant segments, and the first and segments can be fixed with respect to movement toward and away from each other, thereby stabilizing a sacral fracture.

Abstract: A device for treating fractures, comprises a plate receiving structure including on a bone facing side thereof a recess sized and shaped to receive a fixation plate anchored in a desired position on a bone and a mating structure sized and located to engage a corresponding structure of the fixation plate to prevent relative movement between the fixation plate and the device in combination with at least one leg projecting laterally away from the recess, a first one of the at least one legs including a first fixation element receiving hole extending therethrough, the first leg being positioned and oriented so that, when the device is received on a fixation plate anchored to the bone in the desired position, the first fixation element receiving hole is aligned to pass a fixation element inserted therethrough into the bone without passing through a longitudinal axis of the medullary canal.

Abstract: A method is for identifying risks as a result of stray currents which flow to ground from a rail which returns a traction current in a track with a DC power supply. In accordance with a first embodiment, in which the voltage between the rail and ground is measured and an increased risk as a result of stray currents is indicated if there is a discrepancy from a voltage reference value, provision is made for the voltage to be measured at a plurality of measurement points along the track and for the measurements to be evaluated in an evaluation center. In accordance with a second embodiment, provision is made for activating a short-circuiter to connect a parallel path to the rail for returning the traction current. The current level in the parallel path is then measured and an increased risk as a result of stray currents is indicated if there is a discrepancy from a current-level reference value.
