ABSORBABLE INTRAMEDULLARY NAIL FOR FIXING FRACTURES OF LONG TUBULAR BONES Russian patent published in 2019 - IPC A61B17/72 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to intramedullary devices used in traumatology and orthopedics, and is intended for combined osteosynthesis of fractures of long tubular bones. Rod is made in the form of tubular structure including wall and inner cavity. Rod is equipped with fixing elements for rod passing through the wall. Ratio of the wall thickness to the inner cavity diameter makes 1:10–1:5. Intramedullary nail wall includes through holes, the diameter of which makes 0.1–0.3 cm. If the holes diameter is 0.1 cm, their number makes 3–5 with the distance between the holes making at least 0.4 cm, with the hole diameter of 0.2 cm their number is 2–4 with distance between holes of not less than 0.6 cm, with diameter of holes of 0.3 cm their number is 1–2 with distance between holes of not less than 0.7 cm per 1 cm² surface area of the rod.

EFFECT: invention provides higher clinical effectiveness in fractures of long tubular bones with complex architectonics.
