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.

A screwdriver includes a body extending longitudinally from a proximal end to a distal end. The distal end includes a distal screw engaging tip. The screwdriver also includes a slot extending through a width of the screw engaging tip and extending proximally a distance into the body. The slot permits opposed portions of the screw engaging tip to spread apart from one another into a locking configuration in which the opposed portions apply a radially outward force against an interior surface of a recess in a head of a screw into which the screw engaging tip has been inserted to releasably lock the screw engaging tip within the recess.

A device includes an outer sleeve of flexible material forming an outer conduit extending longitudinally therethrough for the insertion of a bone treatment device ('BTD') to target sites within a living body. A distal opening of the outer conduit is open so that, when the outer sleeve is in a desired position within the body, BTD is inserted through the outer conduit exits the outer sleeve adjacent to a target portion of a bone. The device also includes an inner sleeve received within the outer sleeve and defining an inner conduit within the outer conduit to form a protective covering. The inner sleeve is split longitudinally. Portions of the inner sleeve on opposite sides of the split are coupled to one another so that a diameter of the inner conduit is adjustable in response to forces exerted thereon by one of BTD and tissues surrounding the outer sleeve.

Device and system for facilitating insertion of a bone treatment device

In a gate turn-off thyristor (GTO) with homogeneous anode, emitter and stop layer, a device which short-circuit the stop layer with the anode is provided in an edge termination region. As a result, in a reverse-biased state, the GTO has a structure of a diode in the edge region and amplification of a reverse current is obviated. With this structure, thermal loading in the edge region is reduced, as the GTO tolerates a higher operating temperature at a predetermined voltage.

Gate turn-off thyristor with stop layer

A two-stage method is proposed for producing a highly transparent anode emitter (2) in a GTO (1). In a first step, an anode emitter (2) is indiffused whose thickness is greater than 0.5 .mu.m and whose doping concentration is greater than 10.sup.17 cm.sup.-3. In a second step, the emitter efficiency of the anode emitter (2) is subsequently reduced to a desired degree by local carrier life setting.
