FIELD: medicine.
SUBSTANCE: invention relates to medicine, in particular to surgery and orthopedics and can be used for surgically treating degenerative diseases and traumatic spinal injuries in patients with spinal osteoporosis. The method consists in using percutaneous transpedicular screws and a bone-and-plastic material. After the percutaneous access is marked at the levels of the screw insertion on two sides through the legs of the vertebrae through the roots of the legs, trepans are introduced. Channels for access to the bodies of the vertebrae are formed. Screws are carried out through prepared channels in the bodies of the vertebrae and the heads of the screws are fixed to the rods. The trepans are embodied in the form of Jamshidi needles, which are used in the bodies of the vertebrae and are embodied in such a way that cannulated dilatators are introduced into the body of the vertebrae through the legs, forming channels for access to the bodies of the vertebrae. The spokes are removed, through the formed channels transpedicularly, using cannulated dilatators as a guide. Bone funnels are installed in the bodies of the vertebrae, cannulated dilatators are removed, bone crumbs are injected into the body of the vertebrae through bone funnels and are compacted, after which bone crumbs of the vertebrae are filled. Cannulated dilatators are installed repeatedly through bone funnels, through which the spokes are reintroduced. Cannulated dilatators are removed, screws are carried out on the spokes with a channel for the spoke to the point of entry of the spoke into the foot of the vertebrae. The spokes are removed and the screws are carried out in the bodies of the vertebrae, whereupon the rods are percutantly carried out and the heads of the screws are fixed to the rods.
EFFECT: method ensures that the risk of compression of the spinal cord and the spines is eliminated, prevents the risk of the development of a cement pulmonary embolism and preserves the possibility of correcting the position of the screws by means of the cement draining of the vertebrate channel.
