[Morphological evidence of synovial spaces in the uncovertebral region of cervical discs (author's transl)].

The existence of synovial differentiation at the lateral aspect of cervical discuss fissurations up to the development of joint-like spaces with synovial lining have been proved in all decades with the aid of a special investigation technique. A considerable individual variability as well as variable differentiations within the same cervical spine did not allow any correlation between the development of synovial spaces and pathological alterations or pathological load of the spine. The morphogenesis of the described synovial spaces has been discussed with respect to morphological and functional causal factors.
