TRANSOSSEOUS OSTEOSYNTHESIS OF DISTAL-THIRD DIAPHYSEAL HUMERAL FACTURES

Odessa National Medical University, Ukraine

Diaphyseal fractures in the humerus lower third among all fractures in the elbow joint make 30 %. Their treatment is characterized by the greatest difficulties in ensuring stable fixation of fragments, and the results are not always favorable. To solve this problem, a closed minimally invasive controlled rod external fixation technique was developed on the basis of G. A. Ilizarov's apparatus and Osteomechanics, having an external stabilizing support as two segments of one quarter of the ring connected by threaded rods, and located on them two semi−hinged brackets that fix the stabilizing screw rods. The repositioning support is a threaded rod on which the clamp in the form of a "cube" with two mutually perpendicular holes is located. A threaded rod passes through it in the transverse direction, which has semi−hinged brackets at the ends for fixing the repositioning screw rods. The supports are connected by threaded rods hinged by means of single−plane brackets connected by a bolt. The use of semi−hinged brackets provides the ability to fix the screw rods at different angles and the implementation of controlled movements in different planes and directions. According to this method, 26 surgeries were performed. In all cases of application of the offered device intraoperative reposition of fragments, fusion of a humerus in optimum terms and a positive result of an assessment of function of an elbow joint by a technique of Mayo clinic is reached. Based on the results of technical capabilities, it was concluded that the device can be recommended as a method of choice in surgical treatment of humeral fractures at the lower third level.

Key words: humerus, lower third, transosseous osteosynthesis.
