[Neurologic and x-ray aspects of osteochondrosis and diskosis (khondrosis) of the spine].

A certain disparity between the neurological and pathomorphological manifestations of osteochondrosis is reviewed. The authors substantiate the necessity of dividing the dystrophic process in the motor lumbar segment into two phases: 1) the involvement of the disk alone ( diskosis or chondrosis ) and 2) the involvement of both disk and adjacent vertebrae (osteochondrosis). The roentgenological diagnosis of these pathological phases is offered. The question of differentiating the mechanical injuries to the intervertebral disk from osteochondrosis is discussed.
