[Use of demineralized bone sawdust in the treatment of spinal injuries]

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.
