Summary:

Objective: to estimate the changes of effective stresses (by Mises) at three types of loads (axial, lateral and twisting) for various types of intramedullary nails synthesizing modeled fractures of A1; A3; B2 types at the level of femur bone middle third. Material and Methods. To solve the preclinical tasks computer simulation of biomechanical systems bone-fixing pin and method of finite elements were employed. Results. The nails developed by SarNIITO excel ChM and Fixion rods in stress-deformed condition, fatigue strength and stability of fixation of the examined types of fractures parameters of 12- 23%. Conclusion. The mechanical characteristics of SarNIITO nails proved to be of clinical use and may be recommended for patients with femur bone diaphysis fractures.

Intramedullary osteosynthesis in the treatment of humerus fracture consequences

Year: 2018, volume 14 Issue: №3 Pages: 523-529

Summary:

Aim: retrospective analysis of surgical treatment results of patients with the consequences of humerus fractures by locking intramedullary constructions. Material and Methods. 69 patients with ununited fractures and false joints of humerus diaphysis (39 females, 56.7±11.5 yrs (56.5%) and 30 males, 52.3±9.8 yrs (43.5%)) comprised observation group. In the course of surgical intervention they were treated by locking intramedullary rods to perform fragment anchorage, this including 12 patients (17%) with ununited humerus diaphysis fractures after conservative treatment, and 57 (83%) with false humerus joints. Clinical (limb functional restoration) and X-ray (integrity signs) methods were applied for the diagnostics and control of integrity restoration in bone structures; for the assessment of treatment outcomes we used standardized system of outcomes of locomotor fractures and their consequences (SOI-1). Results. Consolidation of the fracture up to 6 months postoperatively was observed in all patients with ununited humerus fractures, treatment outcomes by SOI were 85-94% of anatomic and physiological norm. The consolidation of humerus bone occurred in 50 patients with false joints with

Transosseous osteosynthesis technique in treatment of diaphyseal fractures of shin bones

Year: 2012, volume 8 Issue: №1 Pages: 133-136
Heading: Traumatology and Orthopedics Article type: Original article
Authors: Alfimov R.A., Barabash Yu.A., Simeonov N.S.
Organization: Saratov State Medical University, Central Municipal Hospital of Pyatigorsk
Summary:

Objective: The study of bone tissue repair in different conditions of stability of transosseous fixation (techniques of treatment) of injuries of bones of the shin. Material and methods: Analysis of treatment of 74 patients with unstable diaphyseal fractures of bones of the shin, with the use of different methods of osteosynthesis is carried out. Results: An optimal method of combined transosseous osteosynthesis for treatment of victims with unstable fractures of bones of the shin is offered. Conclusion: A complex approach to the decision of the available problems is offered, consisting in a combination of the use of different types of transosseous elements in the external fixation device which allows to improve results of treatment and to reduce disability period
