METHOD OF TREATING FALSE JOINTS AND INCORRECTLY KNITTED FRACTURES OF LONG TUBULAR BONES AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: group of inventions relates to fields of medicine and medical equipment, and can be applied in treatment of false joints and incorrectly knitted fractures of long tubular bones. Surgical access is performed. Through holes are made in proximal and distal fragments of damaged bone at 1.5-2 cm distance from their ends in zone of pathology at angle of approximately 90° relative to longitudinal bone axis. Bone marrow canals of damaged bone fragments are opened, installation of rod with upper and lower parts is performed intramedullarily. Upper part of rod has regular cylindrical shape, its lower part representing two similar in geometry opposite fragments. The first fragment is made in one piece with upper part of rod, the second being made as a separate fragment. Approximation of fragments until they contact tightly is carried out by its movement into distal fragment of damaged bone and ensuring placement of place where upper part of rod goes into the lower one above or below zone of pathology. Separate fragment of rod is introduced through distal epiphysis of damaged bone until it contacts with the place where upper part of rod goes into the lower one, ensuring ousting bone marrow content via through holes into paraosseous space. After that, fixer is introduced into the central zone of lower part of rod fragments, between them, ensuring internal blocking in the system "rod-bone".

EFFECT: group of inventions makes it possible to accelerate regeneration processes due to performed transfer of maximal amount of bone marrow content into zone of pathology.
