Internal device is actuated by clicker
(lever) after its implanting
Installation of all the necessary
devices is accomplished during one surgery. The actuator for the device
(the clicker) is located under the muscles in the pelvis during the procedure
and is not noticed by the patient.
The clicker is a telescoping
tube that allows itself to be extended as necessary to conform to the patient's
movements.
The clicking process is performed
by the patient using lateral
movements. The patient is usually able to accomplish the clicking by
himself or herself and is a painless process it doesn't require medical
anesthesia.
The device, the clicker and
the screws for their implantation are manufactured of surgical
titanium alloy.
The main functions of the
internal devices are:
-
Firm and durable fixation of
the bone fragments (even without the smallest motions)
-
The Bliskunov device is reliable
for greater extensions than most other devices, and in the case of at least
one patient with a traumatic leg injury provided a 17 cm extension. The
internal device may be compared to a jack (as in an automotive jack). The
device has the heavy construction necessary to overcome the resistance
of the powerful muscles of the extremities. Powerful and reliable devices
are employed by the doctor, which gradually extend the muscle and the bones.
The device may be used to lengthen the bones by 12 cm and more. For instance,
the hip has 28 main muscles; and an effort of dozens of kilograms
is necessary to stretch them. The forces of muscle resistance act constantly
during the lengthening phase and are additional unnatural loads on the
bones and the devices over those naturally imposed by body weight. Therefore,
after the surgery there is need to compensate for these loads with the
use of crutches.
-
Protective function. The Bliskunov
internal devices protect the young bone growth by stabilizing the loads
during the whole lengthening program. Implanting the device inside of the
bone allows a faster recovery and recuperation without the risk of losing
the gains in length achieved due to compressing of the new and soft bone.
The photographs and
the X-rays of the patients before and after the lengthening program are
seen below.
