Summary:

Objective: based on retrospective outcome review of surgical rehabilitation perform assessment of possible usage for intramedullary locking rod structures meant to treat comminuted fractures of humeral shafts. Material and Methods. The intramedullary cross-locking rods were used to fix the fragments. The structures were inserted into humeral shafts by antegrade or retrograde techniques. In most cases surgical interventions were conducted as fracture closed reductions, at that the length and the axis of the limbs were restored without any additional fixation of separate fragments. Results. The review of outcomes for 33 patients with complicated traumatic destructions of humeral shafts showed high efficiency of intramedullary locking rod structures at managing patients with this type of injuries. Conclusion. Small surgical trauma and solid fixation provide for early functional rehabilitation of injured extremities as well as patients» quick return to everyday routine and activity before the fracture heals completely.

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

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
