Method of the nerve root selection in diagnostic and therapeutic process in patients with multilevel nerves entrapment in lumbar spine due to the degenerative process.

This paper presents a method for determining the proper diagnostic techniques and the respective therapy in patients affected with nerve root compression in the lumbar region of the spine based on developing an algorithm that attempts to assess the level of compression and determine the afflicted nerve root. The clinical picture of degenerative disease of the lumbar spine is characterized by symptoms related to the affected nerve root. The diagnosis and respective therapy benefits from the use of minimally invasive techniques, such as selective root blocks or use of the radiofrequency. For instance, with changes on many levels it is necessary to comply with the rules for the selection of the correct nerve roots so there can be referral for proper treatment. The method of selection is dependent on the correlation of the results of the clinical examination, as well as secondary diagnostic studies, of which the gold standard is the MRI. In clinical practice we rely on the results of magnetic resonance imaging to determine the nerve root level in the lumbar spine. This allows the classification of the roots in relation to the frequency of compression occurrence along its course. The morphologic changes resulting in a similar clinical picture may indirectly suggest a degree of exacerbated risk. In addition, we suggest a system of describing the MRI scans, which allows us to retrospectively obtain information on the locations of potential compression of nerve roots.
