ABSTRACT
The authors present the data on positive influence of demineralized osteomatrix (DOM) on the osteogenesis in the experimental conditions. On the basis of data received the method of puncture osteoplastic operation with DOM application was developed. Puncture method was applied in 38 children. In 6 months 31 children cyst were liquidated, osteoarchitectonics was reduced, in 7 children rough trabecular picture remains.

The experimental investigation for the purpose of studying the possibility of intervertebral osseous adhesion formation when demineralized osseous sawdust is introduced in the intervertebral disk in case of penetrating fractures of bodies of vertebra has been carried out. In 70% of cases the osseous adhesion is formed at the level of disks which demineralized osseous sawdust was introduced to (adhesion was formed, mainly, as perifocal osseous stratifications). Osseous adhesion, in case of introduction of lekozim to the damaged disk, was noted in 20% of cases (1 animal). Osteogenesis in disks was absent in all observations in the control group. When used in clinics in 12 patients with injuries of vertebral column in 63.6% of them perivertebral osseous connection has been formed during 8-12 months.

The present paper is the result of the next stage of the studies devoted to prolonged intraarterial introduction of drugs into the tissues of the thoracic spine. For the solution of the problems of surgical provision of this task the authors have worked out the operative approaches to the secondary departments of the posterior intercostal arteries and the technique of their retrograde catheterization on 14 cadavers in 31 experimental operations. This method has been used in the complex treatment of 12 patients with acute and inveterate injuries of the thoracic and the thoracolumbar departments of the spinal column and of the spine. The proposed method appears to be prospective and may be used in the treatment of the patients with tumours, inflammatory and other diseases of the thoracic spine.
