Embodiment Construction

[0048] The same reference signs are used in the figures for the same functional elements and components.

[0049] according to figure 1 First, the underside of the sliding sleeve plate 1 can be seen, but also with the guide sleeve 2 .

[0050] Between the longitudinal axes of the sliding sleeve plate 1 and the guide sleeve 2 there is a predetermined so-called CCD angle, for example in the range between 115° and 150°.

[0051] The sliding sleeve plate 1 can be combined with a rotor support plate 3 which has a plate head 4 which is preferably configured in the shape of a spoon.

[0052] In the plate head 4, there is a block 6 for fixing the target (see figure 2 ) of the threaded hole 5. In addition, screw holes 7 for fixing bone screws 8 are provided. In the embodiment shown, the screw holes 7 are designed in such a way that an angularly variable, stable fixation is possible. The other recesses 9 are used for fixing wires or for fixing Kirschner pins.

Abstract

The invention relates to a device for fixing a bone fractured in the femoral neck region, consisting of a sliding sleeve plate and a trochanteric stabilisation plate, each of which has recesses for receiving bone screws and wherein the plate head of the trochanteric stabilisation plate has an anatomically adapted shape. In addition, the trochanteric stabilisation plate is designed to be applicable to the sliding sleeve plate and moveable along same. According to the invention, at least at the end oriented towards the plate head, the trochanteric stabilisation plate has a profile guide that engages with the sliding sleeve plate from the rear in such a manner that the section of the sliding sleeve plate that is complementary to the profile guide is received and stabilised in a shoe-like manner.

Description

technical field [0001] The invention relates to a device for fixing a fractured bone in the region of the femoral neck according to claim 1, the device comprising a sliding sleeve plate and a rotor support plate for mounting a force carrier, in particular a screw, the sliding sleeve plate The rotor support plate and the rotor support plate each have a recess for receiving bone screws, and the plate head of the rotor support plate has an anatomically adapted shape and the rotor support plate can be placed on the sliding sleeve plate and is configured to be movable. Background technique [0002] Devices for connecting bones fractured in the region of the femoral neck are known from EP0347874A2 or US Pat. No. 4,988,350. This known device is constructed in two parts and comprises a bone fixation splint and a rotor support plate. The bone fixation splint has an angled bone screw mounting sleeve that passes under the trochanter support surface through a splint-like section connec...
