Abstract

Usage: in medicine, namely in traumatology, orthopedics in the treatment of fractures of limbs. The goal is to preserve the integrity of soft tissues at the level of insertion of fixatives. An x-ray with radiopaque marks on the limb and with a measuring ruler is performed. The levels of insertion of the rods are determined, the guidelines are stained with the dye on the extremities at the insertion sites of the rods, the size of the bone diameter is measured at the levels of their insertion, the rod is inserted into the outer cortical layer, the bone diameter from the skin is noted on the rod and the rod is inserted on the measured value. Positive effect: reduced trauma.

Description

The invention relates to medicine, namely to traumatology, orthopedics during osteosynthesis.

The aim of the invention is to maintain the integrity of soft tissues at the level of insertion of fixatives.

The method is performed as follows.

X-ray marks are applied to the skin of the limb at the sites of the intended insertion of the rods, focusing on the fracture site and radiographs. A ruler with radiopaque divisions at the bone level is established, and X-rays are taken. On radiographs, rod insertion levels are refined. The distance from the radiopaque landmarks to the refined levels of insertion of the rods is determined, using the radiopaque divisions of the ruler. The obtained distances are measured from the landmarks of the patient's limb and are marked with paint at these levels. At the marked levels, threaded rods will be inserted into the bone.

The sizes of the bone diameter at different levels are measured using radiopaque centimeter divisions of the ruler. A transverse channel is drilled in the bone with a drill through a 0.5 cm skin incision and a channel in soft tissues made with a blunt instrument. The stem is inserted through soft tissues and screwed into the outer cortical layer of the bone. The size of the bone diameter is measured from the skin on the rod. Screw the rod to the measured value. In the same way. screw rods at other levels. Then, transverse fixation apparatus is attached to the rods.

Example. Patient K., 28 years old, was admitted to the clinic about a closed comminuted fracture of the left hip in the middle third with a displacement of fragments, a fracture of the internal epicondyle of the thigh, and hemarthrosis of the knee joint. On the day of the injury held

fracture anesthesia, knee puncture, skeletal extension. Performed transosseous fixation. The rods were introduced by the proposed method. When measuring the femur width at the level of insertion of the rods on the roentgenogram with the help of the radiographic contrast centimeter divisions of the ruler, it turned out that the bone diameter is 31,31,35 and 50 mm. After inserting the rod into the cortical layer of the bone, the obtained value of the bone diameter was measured on the rod from the skin and the rod was screwed on by this value. After 3 weeks, the dosed load on the legs is allowed.

Fusion occurred after 3.5 months. The patient received a massage and physical therapy. Examined 9.5 months after surgery. He walks, loads his leg. Movement in the joints in full. X-rays showed fusion.
