Description

(54) INTRACTION FIXER

one

The invention relates to medical technology, namely, devices for carrying out osteosynthesis, and can be used for the operative treatment of fractures of tubular bones, clavicle, rib, scapula and pelvic bone.

The intraosseous fixator is known, which contains a rod with a threaded end, a nut mounted on it and a figured washer 1.

However, the known fixative cannot be used to treat fractures of the clavicle, ribs, scapula, pelvic bones (thus, the fixed fixation exerts considerable force on the thin cortical layer, as a result of which the bone tissue is destroyed).

The purpose of the invention is to provide the possibility of treating fractures of the clavicle, ribs, scapula and pelvic bones.

The goal is achieved by the fact that in the intraosseous fixture containing a rod with a threaded end, a nut mounted on it and a figure washer, the other end of the rod is bent at an angle of 20 ° to 90 ° to the axis of the rod, forming a hook.

The drawing shows intraosseous fixative, general view.

The retainer includes a rod 1 with a threaded end 2, a nut 3 mounted on it and a figure washer 4. The other end 5 5 of the rod is bent at an angle of 20-90 ° to the axis of the rod, forming a hook.

The intraosseous fixer is used as follows.

A cut of the skin exposes the Q fracture site in layers and isolates each of the fragments. Using a drill, one of the fragments is drilled in such a way that the drill enters the bone through the medullary canal and leaves the bone at the maximum possible distance from the fracture line. Correspondingly, the skin is cut through the bone out of the drill and the rod 1 is inserted into one of the fragments with its threaded end 2. The fragments are repositioned, after which the rod 1 is inserted with its threaded end 2 2Q into the other fragments so that the retainer is in. crack in the bone-marrow channel of this fragment, and left it at the maximum distance from the fracture line. Through the skin incision made at the exit point of the threaded end 2 of the retainer, first fit the washer 4, and then screw the nut 3, which ensures that the retainer hook engages the bone and reaches the required degree of compression between fragments. Replacing one end of a crk-clamp latch allows it to be successfully used for fractures of long and short tubular bones, collarbone, ribs, shoulder blades, pelvic bones, etc. in the postoperative period. The threaded end of the retainer does not cause trauma to the tissue at its location, since the thread here is intended only to achieve compression between the fragments. Performing a curly washer with a beveled area adjoining directly to the bone at the point of mounting the washer facilitates the use of a fixator with various bone shapes at the point of mounting the washer.

The use of a fixator in clinical conditions, in particular for fractures of the clavicle, reduces the time required for recovery of patients' disability to 1.5 months. instead of 2.5-3.0 months.
