Examples

An example of osteosynthesis of the humerus from fractures with displacement (Fig. 39; 40; 41; 42.).

The apparatus of D. Sharafiev is decomposed into two parts. The first part (Fig. 37) consists of: a clamping device with twin needles and a first knee of a sliding device attached. Second part: second clamping device with twin needles and

the attached third and second elbow of the sliding device.

The first part is brought to the injured limb and the end of the broken bone is clamped by a clamping device (Fig. 39), twisting the pin (8), which is located inside the hole (17).

The lateral lobes (6) are compressed, the paired needles (3) fixed on them strictly against each other pierce the soft tissues of the limbs (skin, muscles) and, thanks to the ability to displace the needles (Fig. 40), they abut against the bone and fix it (Fig. 39) . The screws 16, 20 and 21 on the first part (Fig. 37) of D. D. Sharafiev’s apparatus relax for the free movement of the paired needles and the clamping device along its axis. Then, the second part of D. D. Sharafiev’s apparatus (Fig. 38) joins the first part, the second knee is pushed into the main, first knee.

The second clamping device is brought to the opposite end of the broken bone of the injured limb and also by twisting the stud (8), which is located inside the hole (17), the side blades (6) with fixed strictly against each other

(identical to the first part of D. D. Sharafiev’s apparatus), the opposite part of the injured bone is fixed with paired needles (Fig. 41). The screws 16, 21 also relax on it.

Less often, if necessary, to align the bone along its axis, the screw 22 on the first knee relaxes as well. And screw 20 is clamped and tightly fixes the first part to the second part of D. Sharafiev’s apparatus. Next, the internal screw 32 is slowly untwisted, the third knee begins to extend, thereby pushing the clamping devices with the ends of the broken bone fixed on them in opposite directions and the bone takes on a natural length. Thanks to the mobility of twin needles, clamping devices and

increasing pressure on the bone of the surrounding soft tissues (skin, muscles), the bone assumes an anatomically correct shape. If necessary, help can reduce and correct broken parts of the bone. After aligning the bone fragments, screws 21, 16 and 22 (if used) are tightened and tightly fix the D. D. Sharafiev apparatus in a stationary state (Fig. 42).

The apparatus of D. D. Sharafiev, with the bone aligned and fixed, remains in this position until the bone heals and heals completely. Or, at the doctor’s discretion, on a straightened and fixed bone, it is possible to apply a plaster cast, plates, pin, knitting needle and other bone fixation devices to the limb, after which D. D. Sharafiev’s apparatus can be removed.

The apparatus of D. D. Sharafiev is also easy to remove, the studs (8) on the clamping devices are untwisted, the needles free the bone and soft tissues. After sterilization, repeated, reusable use is possible. Also by this method using the apparatus

Sharafiev D. D. can adjust the length and any curvature of the bone.
