167 children with different variants of congenital obstructions of urinary tracts were examined; the causative agents of urinary tracts infections were analyzed in all the cases. The changes of the cytokines levels were determined in those patients which had the more often found causative agents in the analyses. It was mentioned that of the total patients with obstructive uropathy (OU) the fifth part in the absence of bacteriuria had a pathogen in biopsy material (BM) of urinary tracts. In fourth part of cases microorganisms that were detected in BM and urine did not matched. The changes of cytokines levels in urine did not have any species-specific dependence on causative agent

In this article advantages of external fixation are discussed. Authors investigate regional haemodinamics during treatment of patients with femur fractures. Results of this scientific investigation consist of minimal damaging of local blood supply if surgeons chose external fixation

The present report concerns surgical treatment of unstable thoracic and lumbar spine injuries with the use of ventral approach to vertebral bodies. The use of up-to-date ventral correcting systems and endofixators allows to achieve lasting positive result in such kind of traumas

CII arch fractures are divided into groups according not to anatomical localization, but to the instability degree resulted from the trauma. Effendi et al classification became greatly widespread. |t is based on the same stability criteria, but it is simpler, intelligible and gives the plan of treatment. All the fractures according to this classification are divided into three types: the first one consists in stable fractures in which even in functional images there is no any rough deformation at the level of CII segment; the second one consists in damages with significant angular (more than 11°) or shift (more than 3,5 mm) deformations, that indirectly indicates damage of soft tissue structures, and first of all diskoligamentous complex. The services of the authors of the present classification are also that they were the first who had defined fracture-dislocation of CII arch, attributed it to the third type. Choice of surgical procedure in unstable CII-III vertebral fractures is ventral spondylosyndesis of CII-III carried out by submaxillary approach after the preliminary closed elimination of deformation of upper cervical part of spine. The differentiated approach to the implant choice with an allowance for morphometric data allows to receive adequate decompression of nervous - vascular structures and reliable stabilization of the damaged segment

The given article considers the modern view on etiology, pathogenesis, classifications, clinical picture, diagnosis and treatment of spinal hemangiomas. Advantages of vertebroplasty over the other techniques of treatment of studied pathology are presented

Research objective is to estimate stressful remodelling features of bone tissue according to the densitometry data and to the level of biochemical markers of bone resorption and formation in total hip replacement (THR).
Bone tissue mineral density (BTMD), condition of calcium-phosphoric metabolism and biochemical markers of bone formation (osteocalcin and bone isoenzyme of alkaline phosphatase) and resorption (С-terminal bodypeptide of the I type collagen) have been determined in 52 patients with coxarthrosis of ll-lll stages with marked joint dysfunction before and after THR. The control group included 24 donors. The data were considered to be reliable when the probability index was р<0,05.
The reliable (р<0,05) change of BTMD was determined only in 3-6 months after the operation, whereas the change of biochemical markers of remodeling had already been done after 1,5-3 months, allowing to define the group of patients with obvious negative bone balance: strong predominance of resorption processes without compensation of the subsequent adequate osteogenesis, that subsequently could lead to significant bone tissue deficiency in the area adjacent to the endoprosthesis. Changes of indices of calcium-phosphoric metabolism were not certain during the investigation term.
ln conclusion it is to state that biochemical markers of remodeling in comparison with BTMD allow to estimate objectively features of adaptive bone tissue remodeling after THR in earlier periods and to define group of patients with sharp intensification of metabolism and obvious negative bone balance

The given article concerns with revision hip replacement performed by the construction fixed in intramedullary canal of femur, due to the screw thread applied on the surface of the prosthesis. The example of two-phase hip replacement after the removal of such construction is under the study

In this article questions of femur computer models base making for future it using in free patients medicine are discussed. Last allows possibility for educate doctors using computer models, increase their professional level and makes complications decrease. Comparing of fixation properties of DHS and PFN-A was performed

From 1996 to 2008, the population in Saratov region decreased by 5.6%. From 2006 to 2008, injury indices in the region increased by 4.88%: fractures of thoracic and inferior limbs were caused by osteoporosis, taking into account «population aging». To decrease injury and fracture rates among the population of Saratov region is necessary to raise osteoporosis detection

In the work comparison of two methods of pertrochanteric fracture fixation has been carried out: external one, with the help of the transosseous device and immersed one, by the dynamic femoral system. The investigation of the process of dislocation of fragments has been done on biophantomes. The dynamic compression in the external fixation device increases stability of the biomechanical system «bone-fixator» in 3-4 times. The use of single-stage fracture compression with dynamic femoral system allows to create stable fixation of fragments, adequate for early mobilization of patients
