Fig. 1 The invention relates to medicine, mainly to traumatology, namely to the treatment of tearing fractures of the condyles. A device for reposition and fixation of fractures is known, comprising a housing in which levers are mounted at an acute angle with stop needles fl. The disadvantage of this device is that it is installed on the patient for the entire period of treatment, which creates inconvenience to the patient and limits the use of the device. It is also known a device for reposition and fixation of fractures, containing a bracket on which repairing nodes are placed, including pointed threaded rods, fastening elements 2. However, it is not possible to carry out continuous compression by means of the needles with persistent thickening through intra-articular tear-off condyles. The purpose of the invention is the possibility of fixation of the intraarticular tear-off fractures of the condyles without compression disturbance. This goal is achieved by the fact that in the device for reposition and fixation of fractures, containing a bracket, on which reparation units are placed, including pointed. Threaded rods, fastening elements, reproducing units, are made in the form of a threaded sleeve with a slot, in the channel of which is located the aforementioned hole. rod with a groove under the needle, nut and locking element. FIG. 1 shows the device, a general view; in fig. 2 - repairing node; in fig. 3 - reparation of detachable fragment of condyle; in fig. 4 - holding the spokes. The device consists of a bracket 1 (Fig. 1) with holes 2 in which a repairing unit 3 (Fig. 2) is placed, made of a threaded sleeve 4 with a lock 5, with which it (Fig. 1) is attached to the holes; 2 brackets 1. On sleeve 4 (FIG. 2), a longitudinal slit 6 is made, corresponding to a standard spoke. In the sleeve 4 there is a threaded steribib 7 with an appropriate spine-sided gum / with a corresponding spitephrodol groove 8, one end of the rod is pointed and provided with a fixing nut 9 with a groove 10, and the other end is made in the form of a head 11 with a fixing needle screw 12. The proposed device is used as follows in a way. An epistemological incision of soft tissues is made on both sides no more than 2 cm, not the aponeurosis and the joint capsule are cut. According to the R-gram, retaining nodes 3 are placed in the required amount (2-5) on the bracket 1. Put the proposed device with the pointed ends of the opposing rods 7 on the condyle on both sides. The rods 7 of the repositioning units, placed in the holes 2 of the brackets 1, are set at a given angle and, rotating along the thread, reposition the fragments in its anatomical location, then create a temporary compression. A longitudinal needle 13 is inserted into the longitudinal slot 6 of the sleeve 4 located on the side of the detachable fragment, then it enters the groove 8 of the rod 7 and is fixed on one side with a fixing screw 12, turning her. Then the needle 13 is directed through the tear-off fragment and the bone, fixing the fragment to the bone. Not removing the apparatus and not interrupting the compression, the sleeve 3 is removed from the spoke from the side of its persistent thickening, a lock is put on the sharp end of the spokes and, pulling the needle, the needle is fixed and removed. dosed fragment compression. In addition, the invasiveness of the operation is significantly reduced due to a small incision (no more than 2 cm), preservation of the aponeurosis and the joint capsule. The design of the device is dramatically simplified by using any standard arc with holes and standard needles. This device can be used to reposition and match fragments of long tubular bones with oblique, helical and comminuted fractures, to use as a spoke guide when making the lace and also for treating syndesmosis ( at rupture of the ankle joint and for fractures of the ankle bones.
