[Treatment of patients with open complicated forearm fractures].

The blocking osteosynthesis is preferable in the case of open forearm fractures of the I degree. The treatment of patients with open comminuted complicated forearm fractures should be reasonable to perform in two stages: at the first stage, healing of soft tissues with fixation in the apparatus of external fixation should be obtained. At the second stage, the conversion of external fixator on interlocking nail with single-stage performance of osteoplasty as needed should be carried out.

[Advantages of blocking intramedullary osteosynthesis in treatment of patients with fractures of the forearm bones].

The blocking intramedullary osteosynthesis (BIO) of the forearm bones possesses quite a number of advantages in comparison with the bone and transosseous methods. The BIO allows the restoration of the anatomy and biomechanics of the forearm, it shortens the term of disability and restores the function of the extremity in proximate terms. The BIO of the forearm bones consists of great number of nuances, each of them is really important.

[Application of compressing mini-screws in treatment of patients with intra-articular fractures].

The authors present an experience with the application of compressing headless mini-screws (Herbert screws) in treatment of intra-articular fractures in 37 patients. The mini-screws were used both singly and in combination with other metallic constructions. Long-term results of the treatment were followed up in 21 patients (6 months), in 14 of them excellent results were noted, in 5--good, in 1--satisfactory and in 1--unsatisfactory results.

[Influence of allogenic and autologic multipotent stromal cells of adipose tissue upon bone tissue regeneration in the rabbit mandible angle defect].

Reconstructive surgery often collides with complicated task of defect recovery in the situation of deficit of maxillofacial skeleton tissues, that leads to necessary search of accessible cells source with osteogenic potentials and proper substrate for cell transplantation. In the study the regeneratory potential of stromal cells of adipose tissue was tested in the rabbit model of mandible through angle defect. Cells of allogenic and autologic nature stimulated reparative osteogenesis but their influence upon bone matrix maturation was different.

[Use of mesenchymal stem cells for reparative processes activation in bone jaw tissue in experimental conditions].

In experiment on 12 Chinchilla rabbits dynamics of reparative regeneration was studied at the terms 2 and 4 months. Bone defect in mandible corner was closed by osteoplastic material Gapkol which was covered from inside by allogenic or autologic stem cells received from rabbit adipose tissue. The results of the ray tracing methods of study were verified by SEM and histological methods.
