METHOD AND CONDUCTOR FOR PERFORMING OSTEOSYNTHESIS IN THE CASES OF KNEE PAN FRACTURES Russian patent published in 2001 - IPC

FIELD: medicine; medical engineering. SUBSTANCE: method involves reducing bone fragments, forming canals transversely with respect to fracture line through the bone fragments and fixing knee pan fragments in assembled state. Entry point and exit point corresponding to it are fixed on the fragments of assembled kneepan after performing reposition of the longitudinal axis of one of the canals to be formed. The entry point is fixed relative to the longitudinal axis and exit point of the longitudinal canal of one of the other canals corresponding to it. Wires are conducted through the entry points and exit points corresponding to them. Canals are produced with their lengths controlled and screws are introduced along the wires. Length of each screw is selected in correspondence to the corresponding canal length. Distance between the canals is selected within the limits of 10 to 25 mm. The conductor unit has guiding support member with a unit for deepening and fixing entry point of the longitudinal axis of the canal to be formed, rod with measuring scale for wire, four cylinders and screw-like spring-loaded fixing member. The guiding support members are interconnected by means of flat hinged mechanism and separated by screw-like spring-loaded fixing member. Two of the mentioned cylinders are coaxially mounted on the working parts of each of the guiding support members with axial spaces allowing the fractured bone to be set. The unit for deepening and fixing exit point of a canal to be formed and a rod with measuring scale for wire are coaxially built-in into the corresponding cylinders of each guiding support member. The wire is provided with self-tapping thread. The screw engageable with it has cannula. EFFECT: enhanced accuracy of osteosynthesis; increased operation reliability; prolonged compression; simplified and accelerated treatment. 3 cl, 5 dwg
