[Natural evolution of radiculopathies and myelopathies caused by cervical arthrosis].
OBJECTIVE
From the data available in the literature, to analyse the natural history of acute or chronic radiculopathies and myelopathies linked with degenerative disease of the cervical spine.


METHODS
By means of different electronic and manual search methods, we located original pieces of work dealing with recent objectives and reviews on the subject. We have attempted to take into account any data that might be relevant, regardless of the characteristics or quality of the work in which it was published. The high prevalence of degenerative changes in the cervical region in the general population, the fact that the development of the concept of cervical radiculopathies and myelopathies has gone parallel to the development of their surgical treatment, and that there are few series with a control group and independent evaluation and no trials with random assignation do not allow a systematic approach. The anatomical and radiological aspects of cervical arthrosis are well known, but there is little information available on the causal relation between both processes and their clinical translation or their natural evolution.


CONCLUSIONS
In the present state of knowledge, it is not possible to establish unmistakable relations between cervical disc disease and the radiculopathies and myelopathies it is attributed with. The natural evolution of these neurological syndromes is not known and therefore neither is it known how this could be modified by conservative or surgical treatment. From critical points of view, there is a unanimous claim for clinical trials to be performed with random assignation, which would provide us with an understanding of the natural history of these entities and the role of the different surgical or conservative treatments available
