Intraosteal block was conducted in 86 patients with pronounced neurolo
gical symptoms of lumbar osteochondrosis. To clarify the role of the i
ntraosteal receptors in pathogenesis of the above symptoms and to eval
uate the efficacy of the blocks, series of experiments were made on 8
cats. The authors studied evoked potentials in the cerebral cortex and
thalamus in response to irritation of the sciatic nerve under the exp
osure of the sciatic receptors to electrostimulation, intraosteal intr
oduction of physiologic salt solution and trimecaine, electrostimulati
on following the introduction of the above substances. The pilot exper
ience has been gained on facilitation of afferent current passage from
the sciatic nerve under conditions of intraosteal receptor irritation
as well as on inhibition of the above effect under anesthetic block o
f intraosteal receptors. Basing on the above findings, the authors exp
lain osteogenic mechanism of radiculopathy and pathogenicity of the in
traosteal blocks.
