SU313533A1 - METHOD FOR REPLACING THE DEFECT OF LONG TUBULAR BONE - Google Patents

Description

The invention relates to surgery and relates to methods for replacing a defect of a long tubular bone.

A known method for replacing a long tubular bone defect is that the ends of bone fragments are exposed, a Z-shaped osteotomy of one of the tibial bone fragments is made, two cross spokes are made through the proximal and distal metaphysis, and fixed in the Ilizarov apparatus, and metered stretch.

The proposed method, in contrast to the known, allows one of the fragments of the tibial bone to be lengthened. This is achieved by inserting the curved end of the spoke into the fragment, which, after osteotomy, is fixed in the additional ring of the apparatus.

During the operation, the ends of the fragments in the area of the defect and the area of the fragment to be osteotomy are exposed by a longitudinal incision. Through the fragment, the needle is held in an oblique direction from the side of the central part of its end so that the point of the hole is 2-4 cm from the end. The needle is folded and immersed in the cortical layer of the bone. The second end of the spokes is thus guided through a channel previously drilled at the end of the opposing bone fragment and chipped through soft tissues. Next, produce

Z-shaped osteotomy of the first bone fragment and sutured the wound. The next stage of the operation is to conduct two intersecting spokes through the proximal and distal metaphyses in the plane of the transverse section. The ends of the needles are fixed in the rings of the Ilizarov apparatus. In the additional ring, the end of the spoke is fixed, which is intended to displace the osteotomized bone

fragment. With the help of stretched rods, a dosed stretching of 1.5-2 mm was performed daily by unscrewing the rod nuts by 0.25 turns 6-8 times a day. The cut-off portion of the fragment is gradually shifted towards the defect until it comes into contact with the end of the opposing fragment. Under conditions of stable fixation, a partial or complete defect, formed after displacement of an osteotomized bone fragment, with a newly formed bone tissue, is gradually replaced.
