Intramedullary device for osteosynthesis for comminuted fractures of the proximal femur

摘要

The proposal relates to medicine, namely to traumatology and orthopedics and may be used for the surgical treatment of comminuted (unstable) fractures of the proximal femur. The object of the proposed technical solutions provide a high strength of fixation and rotational stability comminuted (unstable) of the proximal femur. This object, and a positive effect is achieved by the use of intramedullary devices for osteosynthesis in comminuted fractures of the proximal femur, comprising a intramedullary nail with a threaded plug and installed therein distal rotor and locking screws in the bottom part of the rod Intramedullary rod is additionally provided with a proximal rotor, when this on the lateral surface of the intramedullary rod, a groove for installing the locking slide bar and with two holes oval with truncated upper part, and the shape of the groove and moving the locking bar have the same trapezoidal shape with the larger base towards the center of the intramedullary rod, and both rotors formed with stepped abutments for simultaneously locking in corresponding openings of locking the slide bar at a compression threaded plug.
