[Degenerative intervertebral disc processes : Current aspects of diagnosis].

Starting with the smallest functional unit, the spinal segment including the centrally located intervertebral disc, the spine and pelvis including the sacroiliac and hip joints form a functional unit. The discs play an important role in the complex interaction between disc, osseous and ligamentous structures and the adjacent muscles. Disc pathologies are very frequently associated with changes of the adjacent endplates of the vertebral bodies and can be depicted at an early stage using magnetic resonance imaging (MRI). The focus of the diagnostics and assessment of degenerative disc pathologies should be centered on the clinical problem. The basis for this is the use of a uniform terminology between the disciplines involved.
