Abstract

The application of extensible rods while carrying out the intramedullary osteosynthesis minimizes surgical intervention and secures high level of operation and minimum time for the patient’s rehabilitation. Nowadays, medical practice uses the extensible Fixion rod (Israel), which is a circular tube with a guiding and a nipple handipieces and four strengthening ribs. The risk of guiding handipiece damage caused by the peculiarities of its structure, high probability of the bone soft tissue traumas due to the complex kinematics of the ribs movement during the rod usage and high ex-works price limit the application of this rod. Creation of the design eliminating all the above disadvantages is relevant for modern medical industry.

The paper describes the extensible intramedullary rod developed in Togliatti State University in cooperation with Samara State Medical University and the Clinical Hospital №5 of the city of Togliatti.

The rod is a trigonous tube with three welded on strengthening ribs, guiding and nipple handipieces. Before emplacement into the intramedullary (marrowy) canal, the rod is constricted. During the emplacement process, when NaCl solution is being delivered to the rod intracavity under pressure, the rod expands up to its operative condition. A rigid biomechanical system is being formed due to the support of external (contact) surfaces of the ribs as to the mating surfaces of the bone.

The developed rod is secured by the patents and has a number of advantages determined by the structure and proved experimentally. The weight of this rod is on an average 10-15% less than its analogue of the same typical size. The progressive motion of the ribs during the rod expansion process promotes intramedullary tissue minimum traumatization of intramedullary tissue. The risk of guiding handipiece damage is eliminated due to its integral design. The reduction of the number of ribs has caused the reduction of welding seams length and the considerable reduction of the rod production cost.
